This disclosure relates generally to Information Handling Systems (IHSs), and more specifically, to systems and methods for managing text settings based upon user distance with heterogeneous computing platforms.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store it. One option available to users is an Information Handling System (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated.
Variations in IHSs allow for IHSs to be general or configured for a specific user or specific use, such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Historically, IHSs with desktop and laptop form factors have had full-fledged Operating Systems (OSs) (e.g., WINDOWS, LINUX, MAC OS, etc.) executed on “x86” processors. Other types of processors, such as ARM processors, have been associated with smartphones and tablet devices, which typically carry thinner, simpler, or mobile OSs (e.g., ANDROID, iOS, WINDOWS MOBILE, etc.). In recent years, however, IHS manufacturers have started releasing desktop and laptop IHSs equipped with ARM processors, and newer OSs (e.g., WINDOWS on ARM) can now provide users with a more quintessential OS experience on those IHSs.
The inventors hereof have recognized that the IHS industry's transition from x86 to ARM-based processors has created new management, customization, optimization, interaction, servicing, and configuration opportunities for IHS users, Information Technology Decision Makers (ITDMs), and Original Equipment Manufacturers (OEMs).
Systems and methods for managing text settings based upon user distance with heterogeneous computing platforms are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include a heterogeneous computing platform and a memory coupled to the heterogeneous computing platform, where the memory comprises a plurality of sets of firmware instructions, where each of the sets of firmware instructions, upon execution by a respective device among a plurality of devices of the heterogeneous computing platform, enables the respective device to provide a corresponding firmware service, and where at least one of the plurality of devices operates as an orchestrator configured to: receive an indication of a distance between a user and the IHS based, at least in part, upon context or telemetry data; and modify a text setting in a host Operating System (OS) or application executed by the IHS based, at least in part, upon the indication.
For example, the heterogeneous computing platform may include at least one of: a System-On-Chip (SoC), a Field-Programmable Gate Array (FPGA), or an Application-Specific Integrated Circuit (ASIC). The orchestrator may include at least one of: a sensing hub, an Embedded Controller (EC), or a Baseboard Management Controller (BMC).
The orchestrator may be configured to receive a message from a firmware service executed by a selected one of the plurality of devices via an Application Programming Interface (API) without any involvement by any host Operating System (OS) to receive the context or telemetry data. The selected device may include at least one of: a camera or controller, an infrared sensor or controller, a time-of-flight sensor or controller, or a User Presence Detection (UPD) sensor or controller.
To receive the indication, the orchestrator may be configured to request that another device among the plurality of devices calculate the distance based upon the context or telemetry data, where the other device comprises: a high-performance AI device, a low-power AI device, or an audio Digital Signal Processor (aDSP), and where to request that the other device calculate the distance, the orchestrator may be configured to send a message to a firmware service executed by the other device via an API without any involvement by any host OS.
The text setting may include at least one of: a typeface, a font size, a font weight, a font width, or a font color. For instance, in response to an indication that the distance has increased, the orchestrator may be configured to trigger an increase in the font size. Additionally, or alternatively, in response to an indication that the distance has decreased, the orchestrator may be configured to trigger a reduction in the font size. Additionally, or alternatively, in response to an indication that the distance has increased, the orchestrator may be configured to trigger an increase in the font weight. Additionally, or alternatively, in response to an indication that the distance has decreased, the orchestrator may be configured to trigger a reduction in the font weight. Additionally, or alternatively, in response to an indication that the distance has increased, the orchestrator may be configured to trigger an increase in the font width. Additionally, or alternatively, in response to an indication that the distance has decreased, the orchestrator may be configured to trigger a reduction in the font width.
To modify the text setting, the orchestrator may be configured to send a command to the host OS.
The orchestrator may also be configured to: determine that the distance stays constant for a selected period of time; and modify the text setting, at least in part, based upon the determination. The orchestrator may be further configured to: determine that the user's gaze is directed at a display coupled to the IHS for a selected time period; and modify the text setting, at least in part, based upon the determination.
To modify the text setting, the orchestrator may be further configured to receive a policy from an Information Technology Decision Maker (ITDM) or Original Equipment Manufacturer (OEM). The policy may associate the distance with at least one of: the text setting, or the modification to the text setting.
In another illustrative, non-limiting embodiment, a memory device may have a plurality of sets of firmware instructions, where each of the sets of firmware instructions is executable by a respective device among a plurality of devices of a heterogeneous computing platform of an IHS to enable the respective device to provide a corresponding firmware service, and where a given one of the plurality of sets of firmware instructions, upon execution by a given device, cause the selected device to: receive an indication of a distance between a user and the IHS based, at least in part, upon context or telemetry data; determine that the distance stays constant for a selected time period; and modify a text setting in a host OS or application executed by the IHS based, at least in part, upon the determination.
In another illustrative, non-limiting embodiment, a method may include receiving, at an orchestrator from a heterogeneous computing platform of an IHS, context or telemetry data received from one or more of a plurality of devices integrated into the heterogeneous computing platform; determining, by the orchestrator, that distance between a user of the IHS and the IHS stays constant for a selected period of time; and triggering, by the orchestrator, a modification of a text setting in a host OS or application executed by the IHS based, at least in part, upon the determination.

An IHS may also include one or more buses operable to transmit communications between the various hardware components.
The terms “heterogeneous computing platform,” “heterogeneous processor,” or “heterogeneous platform,” as used herein, refer to an Integrated Circuit (IC) or chip (e.g., a System-On-Chip or “SoC,” a Field-Programmable Gate Array or “FPGA,” an Application-Specific Integrated Circuit or “ASIC,” etc.) containing a plurality of discrete processing circuits or semiconductor Intellectual Property (IP) cores (collectively referred to as “SoC devices” or simply “devices”) in a single electronic or semiconductor package. Each device in the platform has different processing capabilities suitable for handling a specific type of computational task. Examples of heterogeneous processors include, but are not limited to: QUALCOMM's SNAPDRAGON, SAMSUNG's EXYNOS, APPLE's “A” SERIES, etc.
ITDM/OEM service(s) 102 may be provided on premises, along with one or more of managed IHSs 101A-N, or may be remotely located with respect to managed IHSs 101A-N. For example, one or more of managed IHSs 101A-N may be deployed within an enterprise, business, or corporation having an ITDM in charge of managing the usage, operation, servicing, configuration, and other aspects of IHSs 101A-N.
Particularly, an ITDM may use one or more management tools executed by ITDM service(s) 102 to establish management channel 104 with managed IHSs 101A-N. Examples of management tools may include, but are not limited to, WINDOWS Admin Center, MICROSOFT Endpoint Configuration Manager, System Center Configuration Manager (SCCM), AZURE, INTUNE, VMWARE WORKSPACE ONE, etc.
ITDM/OEM service(s) 102 may include an ITDM or OEM database. Such a database may include, for instance: an identification of managed IHSs 101A-N (e.g., by service tag, serial number, etc.), an inventory of IHS components installed in managed IHSs 101A-N (e.g., components integrated into managed IHSs 101A-N, peripheral devices coupled to managed IHSs 101A-N, etc.), an identification of a heterogeneous computing platform 300 installed in managed IHSs 101A-N, a list of authorized users, usernames, passwords, logon credentials, cryptographic keys, digital certificates, Operating System (OS) installation or update packages, software application installation or update packages, firmware installation or update packages, hardware policies, software policies, telemetry collected from managed IHSs 101A-N, customer/client support information, etc.

The term “device driver” or “driver,” as used herein, refers to program instructions that operate or control a particular type of device. A driver provides a software interface to hardware devices, enabling an OS and other applications to access hardware functions without needing to know precise details about the hardware being used. When an application invokes a routine in a driver, the driver issues commands to a corresponding device. Once the device sends data back to the driver, the driver may invoke certain routines in the application. Generally, device drivers are hardware dependent and OS-specific.
Still referring to environment 100, any of managed IHSs 101A-N may be in communication with any other one of managed IHSs 101A-N and/or with another, third-party IHS 106, which is not necessarily managed by ITDM/OEM service(s) 102, over network(s) 103.

As depicted, IHS 200 includes host processor(s) 201. In various embodiments, IHS 200 may be a single-processor system, a multi-processor system including two or more processors, and/or a heterogeneous computing platform. Host processor(s) 201 may include any processor capable of executing program instructions, such as a PENTIUM processor, or any general-purpose or embedded processor implementing any of a variety of Instruction Set Architectures (ISAs), such as an x86 or a Reduced Instruction Set Computer (RISC) ISA (e.g., POWERPC, ARM, SPARC, MIPS, etc.).
IHS 200 includes chipset 202 coupled to host processor(s) 201. Chipset 202 may provide host processor(s) 201 with access to several resources. In some cases, chipset 202 may utilize a QuickPath Interconnect (QPI) bus to communicate with host processor(s) 201.
Chipset 202 may also be coupled to communication interface(s) 205 to enable communications between IHS 200 and various wired and/or wireless networks, such as Ethernet, WiFi, BLUETOOTH (BT), cellular or mobile networks (e.g., Code-Division Multiple Access or “CDMA,” Time-Division Multiple Access or “TDMA,” Long-Term Evolution or “LTE,” etc.), satellite networks, or the like.
Communication interface(s) 205 may also be used to communicate with certain peripherals devices (e.g., BT speakers, microphones, headsets, etc.). Moreover, communication interface(s) 205 may be coupled to chipset 202 via a Peripheral Component Interconnect Express (PCIe) bus, or the like.
Chipset 202 may be coupled to display/touch controller(s) 204, which may include one or more or Graphics Processor Units (GPUs) on a graphics bus, such as an Accelerated Graphics Port (AGP) or PCIe bus. As shown, display/touch controller(s) 204 provide video or display signals to one or more display device(s) 211.
Display device(s) 211 may include Liquid Crystal Display (LCD), Light Emitting Diode (LED), organic LED (OLED), or other thin film display technologies. Display device(s) 211 may include a plurality of pixels arranged in a matrix, configured to display visual information, such as text, two-dimensional images, video, three-dimensional images, etc. In some cases, display device(s) 211 may be provided as a single continuous display, or as two or more discrete displays.
Chipset 202 may provide host processor(s) 201 and/or display/touch controller(s) 204 with access to system memory 203. In various embodiments, system memory 203 may be implemented using any suitable memory technology, such as static RAM (SRAM), dynamic RAM (DRAM) or magnetic disks, or any nonvolatile/Flash-type memory, such as a solid-state drive (SSD) or the like.
Chipset 202 may also provide host processor(s) 201 with access to one or more Universal Serial Bus (USB) ports 208, to which one or more peripheral devices may be coupled (e.g., integrated or external webcams, microphones, speakers, etc.).
Chipset 202 may further provide host processor(s) 201 with access to one or more hard disk drives, solid-state drives, optical drives, or other removable-media drives 213.
Chipset 202 may also provide access to one or more user input devices 206, for example, using a super I/O controller or the like. Examples of user input devices 206 include, but are not limited to, microphone(s) 214A, camera(s) 214B, and keyboard/mouse 214N. Other user input devices 206 may include a touchpad, trackpad, stylus or active pen, totem, etc.
Each of user input devices 206 may include a respective controller (e.g., a touchpad may have its own touchpad controller) that interfaces with chipset 202 through a wired or wireless connection (e.g., via communication interfaces(s) 205). In some cases, chipset 202 may also provide access to one or more user output devices (e.g., video projectors, paper printers, 3D printers, loudspeakers, audio headsets, Virtual/Augmented Reality (VR/AR) devices, etc.).
In certain embodiments, chipset 202 may further provide an interface for communications with hardware sensors 210.
Sensors 210 may be disposed on or within the chassis of IHS 200, or otherwise coupled to IHS 200, and may include, but are not limited to: electric, magnetic, radio, optical (e.g., camera, webcam, etc.), light (e.g., Ambient Light Sensor or “ALS”), infrared, thermal (e.g., thermistors, etc.), force, pressure, acoustic (e.g., microphone), ultrasonic, proximity (e.g., User Presence Detection or “UPD” sensor, infrared, time-of-flight or “ToF” sensor, etc.), position, deformation, bending, direction, gaze, eye tracking, body movement, velocity, rotation, gyroscope, Inertial Measurement Unit (IMU), acceleration sensor(s), etc.
Upon booting of IHS 200, host processor(s) 201 may utilize program instructions of Basic Input/Output System (BIOS) 207 to initialize and test hardware components coupled to IHS 200 and to load host OS 400 (
The Unified Extensible Firmware Interface (UEFI) was designed as a successor to BIOS. As a result, many modern IHSs utilize UEFI in addition to or instead of a BIOS. As used herein, BIOS 207 is intended to also encompass a UEFI component.
Embedded Controller (EC) or Baseboard Management Controller (BMC) 209 is operational from the very start of each IHS power reset and handles various tasks not ordinarily handled by host processor(s) 201. Examples of these operations may include, but are not limited to: receiving and processing signals from a keyboard or touchpad, as well as other buttons and switches (e.g., power button, laptop lid switch, etc.), receiving and processing thermal measurements (e.g., performing fan control, CPU and GPU throttling, and emergency shutdown), controlling indicator LEDs (e.g., caps lock, scroll lock, num lock, battery, power, wireless LAN, sleep, etc.), managing PMU/BMU 212, alternating current (AC) adapter/Power Supply Unit (PSU) 215 and/or battery/current limiter 216, allowing remote diagnostics and remediation over network(s) 103, etc.
For example, EC/BMC 209 may implement operations for interfacing with power adapter/PSU 215 in managing power for IHS 200. Such operations may be performed to determine the power status of IHS 200, such as whether IHS 200 is operating from AC adapter/PSU 215 and/or battery 216.
Firmware instructions utilized by EC/BMC 209 may also be used to provide various core operations of IHS 200, such as power management and management of certain modes of IHS 200 (e.g., turbo modes, maximum operating clock frequencies of certain components, etc.).
In addition, EC/BMC 209 may implement operations for detecting certain changes to the physical configuration or posture of IHS 200. For instance, when IHS 200 as a 2-in-1 laptop/tablet form factor, EC/BMC 209 may receive inputs from a lid position or hinge angle sensor 210, and it may use those inputs to determine: whether the two sides of IHS 200 have been latched together to a closed position or a tablet position, the magnitude of a hinge or lid angle, etc. In response to these changes, the EC may enable or disable certain features of IHS 200 (e.g., front or rear facing camera, etc.).
In some cases, EC/BMC 209 may be configured to identify any number of IHS postures, including, but not limited to: laptop, stand, tablet, tent, or book. For example, when display(s) 211 of IHS 200 is open with respect to a horizontal keyboard portion, and the keyboard is facing up, EC/BMC 209 may determine IHS 200 to be in a laptop posture. When display(s) 211 of IHS 200 is open with respect to the horizontal keyboard portion, but the keyboard is facing down (e.g., its keys are against the top surface of a table), EC/BMC 209 may determine IHS 200 to be in a stand posture.
When the back of display(s) 211 is closed against the back of the keyboard portion, EC/BMC 209 may determine IHS 200 to be in a tablet posture. When IHS 200 has two display(s) 211 open side-by-side, EC/BMC 209 may determine IHS 200 to be in a book posture. When IHS 200 has two displays open to form a triangular structure sitting on a horizontal surface, such that a hinge between the displays is at the top vertex of the triangle, EC/BMC 209 may determine IHS 200 to be in a tent posture. In some implementations, EC/BMC 209 may also determine if display(s) 211 of IHS 200 are in a landscape or portrait orientation.
In some cases, EC/BMC 209 may be installed as a Trusted Execution Environment (TEE) component to the motherboard of IHS 200.
Additionally, or alternatively, EC/BMC 209 may be configured to calculate hashes or signatures that uniquely identify individual components of IHS 200. In such scenarios, EC/BMC 209 may calculate a hash value based on the configuration of a hardware and/or software component coupled to IHS 200. For instance, EC/BMC 209 may calculate a hash value based on all firmware and other code or settings stored in an onboard memory of a hardware component.
Hash values may be calculated as part of a trusted process of manufacturing IHS 200 and may be maintained in secure storage as a reference signature. EC/BMC 209 may later recalculate the hash value for a component may compare it against the reference hash value to determine if any modifications have been made to the component, thus indicating that the component has been compromised. In this manner, EC/BMC 209 may validate the integrity of hardware and software components installed in IHS 200.
In various embodiments, IHS 200 may be coupled to an external power source (e.g., AC outlet or mains) through an AC adapter/PSU 215. AC adapter/PSU 215 may include an adapter portion having a central unit (e.g., a power brick, wall charger, or the like) configured to draw power from an AC outlet via a first electrical cord, convert the AC power to direct current (DC) power, and provide DC power to IHS 200 via a second electrical cord.
Additionally, or alternatively, AC adapter/PSU 215 may include an internal or external power supply portion (e.g., a switching power supply, etc.) connected to the second electrical cord and configured to convert AC to DC. AC adapter/PSU 215 may also supply a standby voltage, so that most of IHS 200 can be powered off after preparing for hibernation or shutdown, and powered back on by an event (e.g., remotely via wake-on-LAN, etc.). In general, AC adapter/PSU 215 may have any specific power rating, measured in volts or watts, and any suitable connectors.
IHS 200 may also include internal or external battery 216. Battery 216 may include, for example, a Lithium-ion or Li-ion rechargeable device capable of storing energy sufficient to power IHS 200 for an amount of time, depending upon the IHS's workloads, environmental conditions, etc. In some cases, a battery pack may also contain temperature sensors, voltage regulator circuits, voltage taps, and/or charge-state monitors. For example, battery 216 may include a current limiter, or the like.
In some embodiments, battery 216 may be configured to detect overcurrent or undervoltage conditions using Limits Management Hardware (LMH). As used herein, the term “overcurrent” refers to a condition in an electrical circuit that arises when a normal load current is exceeded (e.g., overloads, short circuits, etc.). Conversely, the term “undervoltage” refers to a condition (e.g., “brownout”) where the applied voltage drops to X % of rated voltage (e.g., 90%), or less, for a predetermined amount of time (e.g., 1 minute).
Power Management Unit (PMU) 212 governs power functions of IHS 200, including AC adapter/PSU 215 and battery 216. For example, PMU 212 may be configured to: monitor power connections and battery charges, charging batteries, control power to other components, devices, or ICs, shut down components when they are left idle, control sleep and power functions (On and Off), managing interfaces for built-in keypad and touchpads, regulate real-time clocks (RTCs), etc.
In some implementations, PMU 212 may include one or more Power Management Integrated Circuits (PMICs) configured to control the flow and direction or electrical power in IHS 200. Particularly, a PMIC may be configured to perform battery management, power source selection, voltage regulation, voltage supervision, undervoltage protection, power sequencing, and/or charging operations. It may also include a DC-to-DC converter to allow dynamic voltage scaling, or the like.
Additionally, or alternatively, PMU 212 may include a Battery Management Unit (BMU) (referred to collectively as “PMU/BMU 212”). AC adapter/PSU 215 may be removably coupled to a battery charge controller within PMU/BMU 212 to provide IHS 200 with a source of DC power from battery cells within battery 216 (e.g., a lithium ion (Li-ion) or nickel metal hydride (NiMH) battery pack including one or more rechargeable batteries). PMU/BMU 212 may include nonvolatile memory and it may be configured to collect and store battery status, charging, and discharging information, and to provide that information to other IHS components, such as, for example devices within heterogeneous computing platform 300 (
Examples of information collected and stored in a memory within PMU/BMU 212 may include, but are not limited to: operating conditions (e.g., battery operating conditions including battery state information such as battery current amplitude and/or current direction, battery voltage, battery charge cycles, battery state of charge, battery state of health, battery temperature, battery usage data such as charging and discharging data; and/or IHS operating conditions such as processor operating speed data, system power management and cooling system settings, state of “system present” pin signal), environmental or contextual information (e.g., such as ambient temperature, relative humidity, system geolocation measured by GPS or triangulation, time and date, etc.), and BMU events.
Examples of BMU events may include, but are not limited to: acceleration or shock events, system transportation events, exposure to elevated temperature for extended time periods, high discharge current rate, combinations of battery voltage, battery current and/or battery temperature (e.g., elevated temperature event at full charge and/or high voltage causes more battery degradation than lower voltage), etc.
In some embodiments, power draw measurements may be conducted with control and monitoring of power supply via PMU/BMU 212. Power draw data may also be monitored with respect to individual components or devices of IHS 200. Whenever applicable, PMU/BMU 212 may administer the execution of a power policy, or the like.
IHS 200 may also include one or more fans 217 configured to cool down one or more components or devices of IHS 200 disposed inside a chassis, case, or housing. Fan(s) 217 may include any fan inside, or attached to, IHS 200 and used for active cooling. Fan(s) 217 may be used to draw cooler air into the case from the outside, expel warm air from inside, and/or move air across a heat sink to cool a particular IHS component. In various embodiments, both axial and sometimes centrifugal (blower/squirrel-cage) fans may be used.
In other embodiments, IHS 200 may not include all the components shown in
For example, in various embodiments described herein, host processor(s) 201 and/or other components of IHS 200 (e.g., chipset 202, display/touch controller(s) 204, communication interface(s) 205, EC/BMC 209, etc.) may be replaced by discrete devices within heterogeneous computing platform 300 (
In various implementations, each device 301-315 in platform 300 may include its own microcontroller(s) or core(s) (e.g., ARM core(s)) and corresponding firmware. In some cases, a device in platform 300 may also include its own hardware-embedded accelerator (e.g., a secondary or co-processing core coupled to a main core).
Each device 301-315 in platform 300 may be accessible through a respective Application Programming Interface (API). Additionally, or alternatively, each device in platform 300 may execute its own OS. Additionally, or alternatively, one or more of devices in platform 300 may be a virtual device.
In certain embodiments, at least one device 301-315 in platform 300 may have updatable firmware which, upon installation, operates to change the performance, available features, settings, configuration options, API, drivers, and/or services provided by that device. For example, each update may be delivered to platform 300 as a system-wide firmware installation package having a plurality of firmware components, and each firmware component may be distributed to its respective device 301-315 (or corresponding memory space).
In some implementations, the latest system-wide firmware installation package received by platform 300 may be installed at every boot of IHS 200.
In the example of
CPU clusters 301A-N are coupled to memory controller 302 via main bus or interconnect 303. Memory controller 302 is responsible for managing memory accesses for all of devices connected to interconnect 303, which may include any communication bus suitable for inter-device communications within an SoC (e.g., Advanced Microcontroller Bus Architecture or “AMBA,” QPI, HyperTransport or “HT,” etc.). All devices coupled to interconnect 303 can communicate with each other and with a host OS executed by CPU clusters 301A-N through interconnect 303.
GPU 304 is a device designed to produce graphical or visual content and to communicate that content to a monitor or display, where the content may be rendered.

Audio Digital Signal Processor (aDSP) 306 is a device designed to perform audio and speech operations and to perform in-line enhancements for audio input(s) and output(s). Examples of audio and speech operations may include, but are not limited to: noise reduction, echo cancellation, directional audio detection, wake word detection, muting and volume controls, filters and effects, etc.
In operation, input and/or output audio streams may pass through and be processed by aDSP 306, which can send the processed audio to other devices 301-315 on interconnect 303 (e.g., CPU clusters 301A-N). aDSP 306 may also be configured to process one or more of platform 300's sensor signals (e.g., gyroscope, accelerometer, pressure, temperature, etc.), low-power vision or camera streams (e.g., for user presence detection, Onlooker Detection, etc.), or battery data (e.g., to calculate a charge or discharge rate, current charge level, etc.). To that end, aDSP 306 may be coupled to BMU 212.
In some cases, aDSP 306 may execute a firmware service configured to: retrieve raw battery data from PMU/BMU 212, preprocess the raw data, and prepare features or attributes (e.g., select, reduce, concatenate, group, etc.) for subsequent processing. Furthermore, to change a PMU/BMU 212 setting, aDSP 306 may communicate with EC/BMC 209 and/or PMU/BMU 212 to request a change to that setting. Examples of PMU/BMU 212 settings may include, but are not limited to: a charge rate ‘C’ (e.g., 0.5 C for slow charges, 0.3 C for trickle charging, 2.5 C for fast charging, etc.), a sustained or average peak power (SPP) parameter, a maximum peak power (MPP) parameter, a maximum charge current (MCC) parameter, etc.

In various implementations, fan controller 315 may be used to operate fan(s) 217. For example, fan controller 315 may be provided to regulate the speed of the fan(s) 217.
Fan controller 315 may receive periodic sensor readings from one or more sensors of the chassis 104 and dynamically adjust the speed of fan(s) 217 using a proportional-integral-derivative (PID) controller algorithm that is fed with sensor data such as, for example: outlet ambient temperature, CPU temperature, Dual In-line Memory Module or “DIMM” temperature, IHS power consumption, etc.
In case of sensor or fan controller failure, fan(s) 217 may be configured to operate at their maximum speed. Additionally, or alternatively, EC/BMC 209 or other platform device (e.g., sensor hub and low-power AI device 307) may send control signals to fan controller 315 to operate fan(s) 217.

Applications 412-414 (and/or host OS 400 components) may use AI models executed by devices within platform 300 for various reasons, ranging from video/audio processing to system optimization tasks. Additionally, or alternatively, ITDMs/OEMs may direct a selected device within platform 300 to act as orchestrator 501A (
Particularly, OS agent(s) 413 may include an OS agent or client configured to communicate with service(s) provided by ITDM/OEM server 102 to establish management channel 104. Moreover, other application(s) 414 may include or be a part of any workload executable by heterogeneous computing platform 300. For example, other application(s) 414 may include productivity, collaboration, streaming, multimedia, or gaming applications executable by host OS 400.
Optimization/customization application(s) 412 may include any host OS 400-level application configured to intelligently optimize the performance of IHS 200 (e.g., DELL OPTIMIZER), for example, by using AI models to dynamically configure IHS 200's settings and/or to optimize the performance of other applications 414. In operation, optimization/customization application(s) 412 may improve the productivity, performance, and user experience through system usage analysis and learning. For example, optimization/customization application(s) 412 may be invoked, within host OS 400, to learn how a selected application 414 is used. Optimization/customization application(s) 412 may identify optimization opportunities, classify users, and automatically apply appropriate settings (e.g., storage, memory, and/or CPU) to improve a selected application 414's performance.
At least one of applications 412-414 may be configured to utilize one or more devices, features, or services exposed, surfaced, enumerated, or otherwise made available by user-mode drivers 407-409, for example, through a Human Interface Device (HID) interface and/or an HID report provided by host OS 400, or the like. In some cases, one or more of applications 412-414 may operate as orchestrator 501A (
In various implementations, host OS 400 may be configured to receive a firmware installation package or executable file containing at least one extension driver (e.g., a setup information or “INF” text file in a driver package) from ITDM/OEM service(s) 102 via management channel 104. The installation package may be processed by a UEFI UpdateCapsule process when distributed as part of an OS update, as a system-wide and/or device-specific firmware update, and/or it may be distributed by OEM update applications such as DELL COMMAND UPDATE, integrated with remote deployment and update management tools.
Firmware components of each extension driver may be loaded, attached, or extended onto user-mode platform drivers and services 407, and may be communicated by user-mode platform drivers and services 407 to respective devices of heterogeneous computing platform 300 through kernel-mode platform drivers 406 for installation, update, or execution of such firmware components in those devices.
As such, the deployment of extension drivers by host OS 400 as OEM drivers 408 provides value-added features or services to user-mode platform drivers (e.g., base drivers) 407 and/or applications 412-414. Particularly, OEM drivers 408 may expose custom services and routines provided by any one of devices 301-315 upon execution of their corresponding firmware components. In some cases, OEM driver 408 may also operate as orchestrator 501A (
Each of APIs 502A-N provides access to firmware 503A-N executed by a corresponding device 501A-N. In operation, each firmware component 503A-N may exchange data and commands directly with each other using APIs 502A-N. Through APIs 502A-N, one or more of devices 501A-N may be configured to enable, disable, or modify firmware services provided by other devices 503A-N. For example, in some embodiments, one or more of devices 501A-N may be designated as orchestrator 501A (
In various embodiments, firmware services resulting from the execution of firmware 503A-N may be provided by their respective device 501A-N to other devices 501A-N within heterogeneous computing platform 300 autonomously and/or independently of the operation of host OS 400. Communications between executing firmware 503A-N and applications 412-414 may take place through OEM drivers 408. In some cases, executing firmware 503A-N may be identified by or exposed to host OS 400 and/or applications 412-414 as part of HID reports.
Firmware service(s) 601A-N and/or corresponding OEM drivers 408 may be installed, modified, updated, and/or removed from IHS 200 upon each installation of a firmware installation package for the entire heterogeneous computing platform 300, for example, at each boot of IHS 200. For example, each firmware component 503A-N providing a respective firmware service(s) 601A-N may be delivered to a respective device 501A-N as an extension driver.
Upon execution, firmware service(s) 601A-N may provide additional controls over the management, deployment, customization, and/or configuration of IHS 200 to the ITDM or OEM that are independent of updates to host OS 400 and/or applications 412-414.
In other embodiments, any given one of devices 501A-N may be rebooted or reset independently of the other devices to perform a local installation, update, or modification of that given device's firmware service(s) 601A-N without having to reboot the entire heterogeneous computing platform 300 and/or IHS 200. Additionally, or alternatively, one or more of devices 501A-N may have its firmware service(s) 601A-N at least partially installed or updated without rebooting or resetting the device.
Orchestrator 501A may be configured to provide firmware service(s) 601A through the execution of firmware 503A. Similarly, each of devices 501B-N may be configured to provide their own firmware service(s) 601B-N through the execution of firmware 503B-N. Moreover, each of firmware service(s) 601A-N may operate independently of host OS 400.
Firmware service(s) 601A of orchestrator 501A may be configured to facilitate the communication of data, commands, AI models, scripts, and/or routines among firmware service(s) 601B-N of devices 601B-N via APIs 502B-N. Additionally, or alternatively, firmware service(s) 601B-N may exchange data and commands with each other using APIs 502B-N.
For example, in some cases orchestrator 501A may be implemented by sensor hub and low-power AI device 307 and/or by EC/BMC 209. GPU 304 may execute firmware service(s) 601B, high-performance AI device 308 may execute firmware service(s) 601C, aDSP 306 may execute firmware service(s) 601D, display 309 may execute firmware service(s) 601E, and other devices 501F-N (e.g., modem 313, peripherals 314, etc.) may execute respective ones of firmware service(s) 601F-N. Firmware service(s) 601A-N may be performed through the execution of firmware components 503A-N previously distributed as extension drivers in a heterogeneous computing platform 300-wide firmware installation package.
Orchestrator 501A may be configured to operate a plurality of devices 501B-N and to receive context and/or telemetry data therefrom. In this manner, orchestrator 501A may be configured to enable IHS users, ITDMs, and/or OEMs to manage, deploy, customize, and/or configure IHS 200 and/or applications 412-414, for example, based upon contextual and/or telemetry-based rules.
As used herein, the terms “context data” or “contextual data” refer broadly to any relevant, background information that can provide a broader understanding of an entity or event. Generally, context data may come from various sources, and it may be used to provide insights into an IHS's operation and/or of a user's behavior patterns, thereby improving their experience.
Examples of context data accessible by orchestrator 501A (
For instance, context data may be used to identify presence hint(s) and/or user engagement cue(s). As used herein, the term “presence hints” refers to any information usable to characterize whether a user is present or absent before IHS 200 and/or a distance between the user of IHS 200. For example, presence hints may include (or be derived from) data received from presence or proximity sensors 210, camera 310, peripheral devices 314 (e.g., whether the user is typing at a keyboard or moving a mouse), etc.
The term “user engagement cue” refers to any user's action, such as utterances, movements, stances, gestures (e.g., fingers, hand, arm, head, body, etc.), or other behavior indicative of whether and/or to what degree a user is engaged with aspects of IHS 200 and/or applications 412-414.
In various implementations, to identify a user engagement cue, one or more devices in heterogeneous computing platform 300 may be configured to perform speech and/or gesture recognition operations based on audio and/or video data streams captured with microphone(s) 214A and/or camera(s) 214B. Moreover, to determine a level of engagement of a user, orchestrator 501A may keep track of one or more engagement cues and calculate an engagement score based upon the number, frequency of occurrence, and/or weight of the detected cue(s).
The term “telemetry data,” as used herein, refers to information resulting from in situ collection of measurements or other data by devices 301-315, or any other IHS device or component, and its transmission (e.g., automatically) to a receiving entity, such as orchestrator 501A (
For instance, telemetry data may include, but is not limited to, measurements, metrics, logs, or other information related to: current or average utilization of devices 301-315 or other IHS components, CPU/core loads, instant or average power consumption of devices 301-315 or other IHS components, instant or average memory usage by devices 301-315 or other IHS components, characteristics of a network or radio system (e.g., WiFi vs. 5G, bandwidth, latency, errors, etc.), keyboard, mice, trackpad, or trackball usage data, transaction times, latencies, response codes, errors, data collected from sensors 210, etc.
It should be noted that, in some implementations, there may be overlap between context data and telemetry data and/or sources. In other implementations, however, context data, telemetry data, and/or their respective sources may be distinct from each other.
In various embodiments, systems and methods described herein may enable an ITDM or OEM to manage, deploy, customize, and/or configure aspects of IHS 200 through orchestrator 501A based, at least in part, upon context and/or telemetry data. For example, ITDM/OEM service(s) 102 may provide one or more devices 501A-N with firmware components 503A-N that, upon execution by their respective devices, add, remove, or modify services accessible to one or more application(s) 412-414 based upon the context and/or telemetry data.
Particularly, orchestrator 501A may receive message(s), file(s), command(s), script(s), and/or ITDM/OEM management polic(ies) 602 (e.g., an Extensible Markup Language or “XML”, a JavaScript Object Notation or “JSON” file, etc.) from ITDM/OEM service(s) 102 via OS agent(s) 413 (i.e., in-band).
When management channel 104 is an OOB channel between EC/BMC 209 and ITDM/OEM service(s) 102, OS agent(s) 413 may be replaced with EC/BMC 209.
In some cases, along with polic(ies) 602, OS agent(s) 413 may also receive one or more AI models and/or AI model parameters for use by a device within platform 300, such as high-performance AI device 308 and/or sensor hub and low-power AI device 307. AI models and/or parameters may be provided to OS agent(s) 413 by ITDM/OEM service(s) 102 or by third-party service(s) 105.
Polic(ies) 602 may contain commands, program instructions, routines, and/or rules that conform to APIs 502A-N. Alternatively, or alternatively, orchestrator 501A may interpret polic(ies) 602 and issue commands conforming to APIs 502A-N. Using APIs 502B-N, orchestrator 501A may be configured to enable, disable, or modify firmware service(s) 601B-N based upon instructions conveyed in polic(ies) 602 (e.g., in response to changes in context, telemetry, etc.) without the involvement of host OS 400.
For example, based upon polic(ies) 602, orchestrator 501A may install, update, modify, enable or disable any of firmware service(s) 601A-N in each of devices 501A-N in response to the detection of one or more of: an IHS location, an IHS posture (e.g., lid closed, etc.), an IHS identification (e.g., service tag, serial number, etc.), a type of IHS (e.g., manufacturer, model, etc.), an identification or type of heterogeneous computing platform 300, an IHS battery (dis)charge level or rate, an identity or type of connected or available IHS peripherals, a security posture of IHS 200 (e.g., connected to VPN, disposed in a trusted or secure location, etc.), an identity or type of applications 412-414 executed by host OS 400, an identity or type of one of applications 412-414 requesting firmware service(s) 601A-N (e.g., via OEM driver 408), an identification of a user of the IHS, an identification of a user group or role, a user's proximity to the IHS, a user's level of user engagement, detected onlooker(s), a user's personal information (e.g., languages spoken, video or audio preferences, etc.), calendar events or data (e.g., type, time, and duration of a collaboration session, priority or importance of the session, role of the user in the session, recurring status, identities and roles of other participants in the session, etc.), messaging (e.g., email, text messages, etc.) data (e.g., subject, date sent and received, number of related messages, priority, names and roles of addressees, etc.), environmental conditions (e.g., weather, background noise levels, lighting level or quality, etc.), etc.
In some cases, polic(ies) 602 may specify that orchestrator 501A select one or more of a plurality of different AI models (or different instances of the same AI model) to be used for a given operation in response to the IHS being at a certain geographic location, network location, type of audio environment, etc. Any of the contextual and/or telemetry information described herein may be used to create different sets of conditions for rules outlined in polic(ies) 602.
For example, polic(ies) 602 may specify that high-performance AI device 308 be used to apply a more computationally costly AI model (or a larger number of models) under a favorable set of conditions (e.g., if battery level is above a first threshold level, if IHS 200 is connected to AC power, if a certain application or type of application is in execution, if a level of utilization of high-performance AI device 308 and/or sensor hub and low-power AI device 307 is below a threshold level, etc.).
Under a set of less favorable conditions (e.g., if battery level is below a second threshold level, if a certain application or type of application is not in execution, if a level of utilization of high-performance AI device 308 is above a threshold level, etc.), however, polic(ies) 602 may specify that sensor hub and low-power AI device 307 be used to apply a less computationally costly AI model (or fewer models).
In some cases, polic(ies) 602 may also determine whether or under what conditions the user many manually override its rules and settings (e.g., turn a camera or microphone on or off, enable or disable a filter or effect, etc.). Moreover, for different types of users (e.g., engineer, customer support, executive, etc.) who tend to interact with their IHSs 101A-N in different ways, ITDM/OEM service(s) 102 may deploy different rules, AI models, and/or parameters by selecting and deploying different polic(ies) 602.
In many scenarios, systems and methods described herein may enable the collection and management of context and/or telemetry data from one or more of devices 501A-N, host OS 400, and/or applications 412-414.
In that regard,
At 701, orchestrator 501A may receive polic(ies) 602. Polic(ies) 602 may be selected by ITDM/OEM service 102 (e.g., based upon the identities of IHSs 101A-N, service tags, network addresses, user IDs, etc.) and may include rules and/or parameters usable by orchestrator 501A to manage context and/or telemetry data collection operations autonomously and/or independently of host OS 400.
For example, polic(ies) 602 may identify one or more of: context and/or telemetry data to be collected, devices to collect the context and/or telemetry data from, context and/or telemetry data collection parameters (e.g., collection frequency or sampling rate, collection start and end times, a duration of the collection, a maximum amount of telemetry data to be collected, etc.), context and/or telemetry data collection routines, scripts, and algorithms to process and/or produce the context and/or telemetry data, etc. In some cases, each individual piece or set of context and/or telemetry data may include a common clock time stamp (e.g., if requested by polic(ies) 602).
At 702, orchestrator 501A may select one or more devices (e.g., among devices 301-315 of heterogeneous computing platform 300) to collect context and/or telemetry data from, based upon polic(ies) 602. In some cases, selected devices may be dynamically chosen by orchestrator 501A based upon previously collected context and/or telemetry data, as also outlined in polic(ies) 602.
At 703, firmware service(s) 601A of orchestrator 501A may send message(s) to one or more of firmware service(s) 601B-N of selected devices 501A-B with instructions about how to collect any identified context and/or telemetry data and/or how to deliver the collected context and/or telemetry data. For example, such message(s) may inform a given context and/or telemetry collection device which other device(s) to deliver the collected data to, acceptable data format(s) or protocol(s), the manner and/or frequency of data delivery, etc. Moreover, these message(s) may be transmitted between firmware services(s) 601A-N without any involvement by host OS 400.
Firmware service(s) 601A may transmit context and/or telemetry collection messages to any given one of firmware service(s) 601B-N executed by devices 501B-N using a respective one of APIs 502A-N. Conversely, firmware service(s) 601B-N of devices 501B-N may send messages (e.g., acknowledgement, device status, context and/or telemetry data collected, etc.) to firmware service(s) 601A orchestrator 501A using API 502A, again without any involvement by host OS 400. Then, at 704, firmware service(s) 601A of orchestrator 501A receives context and/or telemetry data from selected devices 501B-N following API 502A.
In various implementations, the collected context and/or telemetry data may be used by orchestrator 501A to enforce a wide variety of management decisions based upon polic(ies) 602. Additionally, or alternatively, the collected context and/or telemetry data may be input into AI model(s) executed by device(s) 501A-N.
In some cases, method 700 may be performed at the request of applications 412-414. By maintaining all context and/or telemetry collection routines in firmware 503A-N, method 700 addresses concerns associated with the excessive consumption of IHS resources by OS-level telemetry collection software. When orchestrator 501A serves as the only point of contact for all context and/or telemetry requests targeting devices 501A-N, it may output a stream of context and/or telemetry data to host OS 400.
At 801, orchestrator 501A may receive polic(ies) 602 selected by ITDM/OEM service 102 (e.g., based upon the identities of IHSs 101A-N).
At 802, orchestrator 501A may initiate and/or manage context and/or telemetry data collection operations autonomously and/or independently of host OS 400, as shown in method 700 (
At 803, orchestrator 501A may select device(s) 301-315 onto which to deploy selected AI model(s) and/or AI model parameters as a function on context and/or telemetry data collected at 802 based upon polic(ies) 602. Non-limiting examples of AI model parameters that can be modified and/or influenced during runtime include weights (w) and biases (b).
A “weight” is a type of model parameter that controls a signal (or the strength of the connection) between two neurons (e.g., it determines how much influence the input will have on the output). Conversely, a “bias” is another type of model parameter that provides an additional input into the next layer with a constant value, which is not influenced by the previous layer, but rather has an outgoing connection (with its own weight). In some cases, a bias value of ‘1’ may guarantee that, in a neural network, even when all the inputs are zeros, a particular neuron is activated; whereas a bias value of ‘0’ deactivates that neuron.
Modifying weights or biases may change the structure of a neural network, which in turn modifies an AI model's performance, power consumption, inference accuracy, and/or speed of execution.
In some cases, orchestrator 501A may use at least a subset of context and/or telemetry information—and/or it uses AI mode inferences produced based upon the subset of context and/or telemetry information—to enforce the execution of AI models following rules indicated ITDM/OEM polic(ies) 602. In that regard, it should be noted that an ITDM/OEM may set use polic(ies) 602 to enforce unique rules, triggers, and/or thresholds for selecting AI processing settings for different ones of IHSs 101A-N (or groups of IHSs) with different levels of granularity, based on context and/or telemetry data.
For example, at 803, orchestrator 501A may enforce a policy rule which dictates that a particular device within heterogeneous computing platform 300 be selected to execute a specific AI model (or type of AI model) with certain parameter(s) in response to different context and/or telemetry data, such as, for example: when an IHS is on battery power (or when the battery charge drops below or rises above a minimum value), when the IHS 200 is in a certain location (e.g., at work, at home, within a distance from selected coordinates, etc.), based on hardware utilization (e.g., a level of utilization of one or more of the devices in platform 300 reaches a maximum or minimum value), if the user of IHS 200 belongs to a selected group of users (e.g., “managers,” “engineers,” etc.), when IHS 200 is manipulated into a given posture, when the user is present or within a selected distance from IHS 200, etc.
At 804, orchestrator may deploy the selected AI model(s) and/or AI model parameters onto selected device(S) 301-315. Generally, an AI model may be executed or deployed as a service. In some cases, a container system (e.g., DOCKER, KUBERNETES, etc.) may operate as a “box” for an AI model that creates reproducible, scalable, and isolated environments where users can set up dependencies so the AI model can work in any desired execution environment, such as, for example, a selected one of the plurality of devices in heterogeneous computing platform 300 (
At 805, orchestrator 501A may determine if there are any context and/or telemetry data changes (e.g., if the latest data has a value different than a previously collected data value by an amount greater than or equal to a threshold value). If not, control stays with 805. If so, control returns to 803, where orchestrator 501A may select different device(s), AI model(s), and/or parameter(s) to initiate new AI processes or give continuance to ongoing AI processes (e.g., AI model migration).
As such, method 800 provides a mechanism for orchestrator 501A to dynamically modify the provisioning of AI services by heterogeneous computing platform 300 autonomously and/or independently of host OS 400.
In various embodiments, workload characterization AI model(s) may be provisioned and deployed with firmware service(s) 601A and executed by high-performance AI device 308. The output(s) of these workload characterization AI model(s) may include the detection and determination of system state, usage, and/or workloads (and their intensities), and delivered to firmware service(s) 601A.
Other firmware service(s) 601B-N (e.g., aDSP 306, display 309, camera 310, etc.) may receive configuration commands from firmware service(s) 601A to modify IHS settings based upon outputs from the workload characterization model(s), for example, as prescribed by polic(ies) 602. In some cases, host OS 400 may include its own service configured to provide certain configuration modifications (e.g., outside of driver configuration load/mechanisms) and manage and interface with HID input to alert a user of selected operations, and to direct management interfaces to remote services.
At 901, firmware service(s) 601A executed by orchestrator 501A receives polic(ies) 602 selected by ITDM/OEM service 102 (e.g., based upon the identities of IHSs 101A-N). At 902, orchestrator 501A may select one or more of devices 501A-N to deploy usage or workload characterization model(s) with parameter(s) selected based upon instructions or rules included in polic(ies) 602. For example, a workload characterization model may be trained to receive context and/or telemetry data as inputs and to identify one or more workloads (or types of workloads) in execution.
In some cases, block 902 may also include collecting context and/or telemetry data, for example, as described in method 700 (
Block 902 may further include deploying workload characterization AI model(s) in selected device(s). For instance, orchestrator 501A may send message(s) to firmware service(s) provided by selected device(s) (e.g., high-performance AI device 308), without any involvement by host OS 400 to load and execute the workload characterization model(s).
In some implementations, polic(ies) 602 may identify at least one of: the context or telemetry data to be collected, the subset of the plurality of devices from which to collect the context and/or telemetry data, the one or more selected devices for executing one or more selected AI models, or an identification of the one or more AI models. Polic(ies) 602 may also include one or more rules that associate at least one of: (a) the one or more selected devices, or (b) the one or more AI models with predetermined context or telemetry data. In such implementations, orchestrator 501A may be configured to enforce rules, at least in part, based upon a comparison between current context and/or telemetry and the predetermined context and/or telemetry data.
At 903, the selected device(s) may characterize one or more workload(s) of IHS 200 using the workload characterization model(s). In some cases, a workload characterization model may identify patterns of utilization (e.g., core, memory, battery, network, peripherals, etc.) by certain devices 501A-N that are indicative of an ongoing collaboration session, a video game session, a productivity session (e.g., document processor, spreadsheets, presentations, email client, etc.), etc.
Additionally, or alternatively, a workload characterization model may identify patterns of utilization of different types of workloads (e.g., productivity, collaboration, browsing, streaming, video games, etc.) and/or their intensity. In some cases, such workload characterization results may indicate that X % of available IHS resources are executing a first type of workload and Y % of those resources are executing a second type of workload, concurrently. The selected device(s) may then send an indication of workload characterization results to orchestrator 501A without any involvement by host OS 400.
At 904, orchestrator 501A may change one or more IHS settings based, at least in part, upon the characterization results, as instructed by polic(ies) 602. For instance, polic(ies) 602 may include rules that indicate, for each characterized workload, what one or more settings should be. Additionally, or alternatively, polic(ies) 602 may require orchestrator 501A to execute another type of AI model that receives characterization results and/or other context and/or telemetry data as inputs, and that infers the appropriate settings for a given workload.
Examples of IHS settings may include, for at least one of the plurality of devices 501A-N, at least one of: a power state, a maximum power consumption, a clock speed, a turbo frequency, a multithreading feature, the availability of an accelerator, or a memory allocation. Additionally, or alternatively, IHS settings may include at least one of: a display's brightness, a display's resolution, a display's color depth, a display's refresh rate, a microphone's gain, or a speaker's volume, a camera's capture resolution, or a camera's refresh rate. Additionally, or alternatively, IHS settings may include, for at least one of the characterized one or more workloads, at least one of: a network bandwidth, or a connection priority.
At 905, orchestrator 501A may notify at least one of: host OS 400, any of applications 412-414, or a user of IHS 200 about the characterization of the one or more workloads and/or the settings referred to in 904.
At 906, orchestrator 501A may determine if the context and/or telemetry data has changed (e.g., by an amount greater than a threshold value). If so, control returns to 902 where new device(s), AI model(s), and/or parameters may be selected and deployed based upon the application of polic(ies) 602 to the changed context and/or telemetry data. If not, control passes to 907.
At 907, orchestrator 501A determines if there have been changes to one or more workload(s). If not, control returns to 906. If so, control passes to 903, where the new or changed workloads may be (re)characterized.
In some scenarios, a user may be working from home while attending a meeting via a conferencing application, when at some point during the meeting they may stand up to stretch their legs, for example. As their eyes move farther away from the display, the font size of the content presented in the meeting may appear smaller and difficult to read. In other scenarios, the user may be finished with the meeting and may approach the display to work on a document editor, such that a typical font size now appears larger; yet could be made smaller to effectively increase the display area productivity purposes. In yet other scenarios, a particular user may operate IHS 200 in a public location (e.g., a library) where font sizes are displayed for an average user, but which may be too small for this particular user, thus resulting in reading difficulties.
More generally, there is no firmware-based mechanism to contextually change host OS and/or application settings for fonts, for example, based upon what the user is doing (e.g., to help reduce eye strain).
To address these, and other concerns, systems and methods described herein may provide tools for managing text settings based upon user distance in heterogeneous computing platforms. In various cases, these systems and methods may use contextual and/or telemetry data to modify text settings (e.g., a typeface, a font size, a font weight, a font width, a font color, etc.) used by host OS and/or any individual application (e.g., an application in the foreground), for instance, based upon polic(ies) 602. Moreover, these systems and methods may provide a firmware service set configured to modify text settings, in co-operation with host OS 400, based upon indications of user distance from an IHS's display.
In some implementations, firmware service(s) 601A running in orchestrator 501A may be responsible for modifying text settings based, at least in part, upon context or telemetry data received from other devices (e.g., user distance or proximity to IHS 200 and/or display device(s) 211), for example, as prescribed by polic(ies) 602. In addition, firmware service(s) 601A may notify any suitable OS service within OS 400 for user notification and OS-level actions.
In some cases, polic(ies) 602 may be received and processed by firmware service(s) 601B executed by EC/BMC 209 (e.g., out-of-band through management channel 104), and, in cases where orchestrator 501A is implemented by sensor hub 307, EC/BMC 209 may transmit polic(ies) 602 or portions thereof to sensor hub 307 for enforcement of rule(s) related to text settings.
Firmware service(s) 601C running on camera controller 310 and/or sensors 210 may be configured to detect a user's distance from IHS 200 and to transmit user distance indications to firmware service(s) 601A. In other cases, however, user distance indications may be provided by a Human Presence Detect (HPD) stacked implemented within host OS 400.
Additionally, or alternatively, firmware service(s) 601C running on camera controller 310 and/or sensors 210 may be configured to detect the user's gaze and/or track the user's eyes and to transmit user gaze (e.g., detected or lost) and/or eye tracking indications (e.g., direction of sight) to firmware service(s) 601A. In some cases, firmware service(s) 601A may also be configured to correlate the user's gaze with a particular application window rendered on display device(s) 211 using contextual or telemetry data received from display controller 309, and/or Graphical User Interface (GUI) data received from host OS 400.
Host OS 400 may receive user distance indications from firmware service(s) 601A and/or instructions to modify a text setting, in host 400 itself and/or any application in execution. Examples of other host OS 400's behaviors may include, but are not limited to, updating firmware service(s) 601A with user settings and/or modifying ITDM's policy settings and configurations.
In some cases, application service(s) (e.g., 408, 413, etc.) in host OS 400 may receive user presence and/or distance data from firmware service(s) 601A (or an HPD stack in host OS 400), examine metadata associated with these notifications to determine if the user's distance stays constant for a specific duration, and configure host OS 400 and/or an application (e.g., 414) to set text settings (e.g., font size) according to that distance, as per polic(ies) 602.
ITDM/OEM service(s) 102 may provide a remote management console responsible for configuring system policy and settings configurations to manage system thresholds and policy settings. In other implementations, however, such management console may be provided locally. Polic(ies) 602 may be implemented through host OS 400 or through remote management via firmware service(s) 601B of EC/BMC 209.
To illustrate the foregoing,
Particularly, method 1000 may be performed, at least in part, through the execution of firmware instructions 503A by orchestrator 501A within heterogeneous computing platform 300 (
At 1001, firmware service(s) 601A executed by orchestrator 501A may receive polic(ies) 602 selected by ITDM/OEM service 102 (e.g., based upon identities of IHSs 101A-N).
At 1002, orchestrator 501A may instruct one or more of devices 501B-N to collect context and/or telemetry data, as previously described. Polic(ies) 602 may identify the context and/or telemetry data to be collected (e.g., user presence, distance, gaze, etc.), and/or the set of devices from which to collect the context and/or telemetry data (e.g., camera controller 310, sensors 210, etc.).
Polic(ies) 602 may also include one or more rules, such that each rule associates a user distance, a time that the user distance has been maintained, a user gaze, and/or a time that the user gaze has been maintained—collected as context or telemetry data—with at least one of: a text setting, a modification to a text setting, an application or type of application to which the text setting or the modification to the text setting applies.
At 1003, orchestrator 501A may determine whether the distance of the user to IHS 200 and/or display 211 matches a policy rule. Additionally, or alternatively, at 1003, orchestrator 501A may determine whether the user distance has remained constant for a preset amount of time. Additionally, or alternatively, at 1003, orchestrator 501A may determine whether the user's gaze matches a policy rule. Additionally, or alternatively, at 1003, orchestrator 501A may determine whether the user's gaze has remained constant for a preset amount of time. If not, control returns to 1002 (or 1001).
If so, at 1004, orchestrator 501A may modify (or trigger the modification of) one or more text settings, for example, by communicating the modification to host OS 400 and/or application 414.
For instance, in response to an indication that the user distance has increased, orchestrator 501A may trigger an increase in the font size. Additionally, or alternatively, in response to an indication that the distance has decreased, orchestrator 501A may trigger a reduction in the font size. Additionally, or alternatively, in response to an indication that the distance has increased, orchestrator 501A may trigger an increase in the font weight (e.g., bold). Additionally, or alternatively, in response to an indication that the distance has decreased, orchestrator 501A may trigger a reduction in the font weight. Additionally, or alternatively, in response to an indication that the distance has increased, orchestrator 501A may trigger an increase in the font width (e.g., a space between characters, words, and/or sentences). Additionally, or alternatively, in response to an indication that the distance has decreased, orchestrator 501A may trigger a reduction in the font width.
After 1004, control returns to 1002 (or any preceding operation).
As such, systems and methods described herein may enable firmware-based management of text settings based upon user distance, using user preferences and IT policies. In various embodiments, these systems and methods may reduce the user's eye strain and/or enhance user wellness.
To implement various operations described herein, computer program code (i.e., program instructions for carrying out these operations) may be written in any combination of one or more programming languages, including an object-oriented programming language such as Java, Smalltalk, Python, C++, or the like, conventional procedural programming languages, such as the “C” programming language or similar programming languages, or any of machine learning software. These program instructions may also be stored in a computer readable storage medium that can direct a computer system, other programmable data processing apparatus, controller, or other device to operate in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the operations specified in the block diagram block or blocks.
Program instructions may also be loaded onto a computer, other programmable data processing apparatus, controller, or other device to cause a series of operations to be performed on the computer, or other programmable apparatus or devices, to produce a computer implemented process such that the instructions upon execution provide processes for implementing the operations specified in the block diagram block or blocks.
Modules implemented in software for execution by various types of processors may, for instance, include one or more physical or logical blocks of computer instructions, which may, for instance, be organized as an object or procedure. Nevertheless, the executables of an identified module need not be physically located together but may include disparate instructions stored in different locations which, when joined logically together, include the module and achieve the stated purpose for the module. Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices.
Similarly, operational data may be identified and illustrated herein within modules and may be embodied in any suitable form and organized within any suitable type of data structure. Operational data may be collected as a single data set or may be distributed over different locations including over different storage devices.
Reference is made herein to “configuring” a device or a device “configured to” perform some operation(s). This may include selecting predefined logic blocks and logically associating them. It may also include programming computer software-based logic of a retrofit control device, wiring discrete hardware components, or a combination of thereof. Such configured devices are physically designed to perform the specified operation(s).
Various operations described herein may be implemented in software executed by processing circuitry, hardware, or a combination thereof. The order in which each operation of a given method is performed may be changed, and various operations may be added, reordered, combined, omitted, modified, etc. It is intended that the invention(s) described herein embrace all such modifications and changes and, accordingly, the above description should be regarded in an illustrative rather than a restrictive sense.
Unless stated otherwise, terms such as “first” and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. The terms “coupled” or “operably coupled” are defined as connected, although not necessarily directly, and not necessarily mechanically. The terms “a” and “an” are defined as one or more unless stated otherwise. The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “including”) and “contain” (and any form of contain, such as “contains” and “containing”) are open-ended linking verbs.
As a result, a system, device, or apparatus that “comprises,” “has,” “includes” or “contains” one or more elements possesses those one or more elements but is not limited to possessing only those one or more elements. Similarly, a method or process that “comprises,” “has,” “includes” or “contains” one or more operations possesses those one or more operations but is not limited to possessing only those one or more operations.
Although the invention(s) is/are described herein with reference to specific embodiments, various modifications and changes can be made without departing from the scope of the present invention(s), as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of the present invention(s).
