Patent Application
20200084858
The present application relates generally to an improved data processing apparatus and method and more specifically to mechanisms for automatically providing a user-sensitive amount of light for a specific task.
Lamps, light fixtures, and other lighting devices come in many shapes and sizes. Each of these lighting; devices is provided to accomplish a specific undertaking such as lighting the side of a building or flag, lighting a room or office, or lighting a specific task, commonly referred to as task lighting. Task lighting refers to increasing illuminance to better accomplish a specific activity. However, the illuminance level is not the only factor governing, visibility. Contrast is also important, and a poorly positioned light source may cause contrast reduction, resulting in loss of visibility. The most important purpose of task lighting in the office is not increasing illuminance, but improving contrast. General lighting may be reduced because task lighting provides focused light where needed. Different strategies for task lighting exist. The three, main approaches are:
There are also other approaches to task lighting, for example under-shelf luminaires. Other instances of task lighting are in machinery, where a specific work area needs illumination, and in workshops, where a task light may illuminate the actual working area. Special instances of task lighting are examination and operation lights for medicine and surgery, as well as the dentist's lamp. Task lamps are also used for many home tasks such as sewing, reading, small repairs, model construction, crafts, writing, and many other activities. The actual task may range from very small up to about as far as you may reach with your hands or available tools.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described herein in the Detailed Description. This Summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
In one illustrative embodiment, a method, in a data processing system, is provided for automatically providing a user-sensitive amount of light for a specific task. Responsive to detecting an object being lit by a task-lighting device, the illustrative embodiment identifies a set of lighting conditions associated with lighting the object. The illustrative embodiment utilizes a first set of parameters to adjust an amount of light being emitted by a light emitting device of the task lighting device to light the object. Responsive to a user manually adjusting the amount of light being emitted by the light emitting device thereby forming a current amount of light being emitted by the light emitting device, the illustrative embodiment identifies current lighting condition parameters and the current amount of light being emitted by the light emitting device. The illustrative embodiment stores the current lighting condition parameters and the current amount of light being emitted by the light emitting device as a second set of parameters. The illustrative embodiment utilizes the second set of parameters for adjusting the amount of light being emitted by the light emitting device to light the object when changes to the object occurs,
In other illustrative embodiments, a computer program product comprising a computer useable or readable medium having a computer readable program is provided. The computer readable program, when executed on a computing device, causes the computing device to perform various ones of, and combinations of, the operations outlined above with regard to the method illustrative embodiment.
In yet another illustrative embodiment, a system/apparatus is provided. The system/apparatus may comprise one or more processors and a memory coupled to the one or more processors. The memory may comprise instructions which, when executed by the one or more processors, cause the one or more processors to perform various ones of, and combinations of, the operations outlined above with regard to the method illustrative embodiment.
These and other features and advantages of the present invention will be described in, or will become apparent to those of ordinary skill in the art in view of, the following detailed description of the example embodiments of the present invention.
The invention, as well as a preferred mode of use and further objectives and advantages thereof, will best be understood by reference to the following detailed description of illustrative embodiments when read in conjunction with the accompanying drawings, wherein:
As noted previously, task lighting increasing illuminance and/or contrast to better accomplish a specific activity. While task lighting may provide localized average lighting, freely adjustable task lighting, or asymmetric task lighting, the amount of illuminance and/or contrast provided for a specific task is dependent on the user that is benefiting from the task lighting. Since a user's eyesight changes over the user's lifetime, task lighting for one user may not be the same as task lighting for another user.
Thus, the illustrative embodiments provide a user-sensitive automatic task lighting mechanism for task-lighting devices. The user-sensitive automatic task lighting mechanism detects an object for which task lighting is being utilized and uses feedback, such as luminescence, white-balancing, contrast, or the like, to adjust the amount of light that is being provided by the task-lighting device to light the object. Utilizing a default and/or personalized lighting preferences, the user-sensitive automatic task-lighting mechanism adjusts the lighting behavior provided by the task-lighting device to a comfortable, personalized level to achieve the task being performed by the associated user.

It should be appreciated that once the computing device is configured in one of these ways, the computing device becomes a specialized computing device specifically configured to implement the mechanisms of the illustrative embodiments and is not a general purpose computing device. Moreover, as described hereafter, the implementation of the mechanisms of the illustrative embodiments improves the functionality of the computing device and provides a useful and concrete result that facilitates a user-sensitive automatic task-lighting mechanism.

In some illustrative examples, data processing system 200 may be a portable computing device that is configured with flash memory to provide non-volatile memory for storing operating system files and/or user-generated data, for example. Essentially, data processing system 200 may be any known or later developed data processing system without architectural limitation.
Again, the illustrative embodiments provide a user-sensitive automatic task-lighting mechanism. The user-sensitive automatic task-lighting mechanism utilizes a set of sensors and/or detectors to determine an object that is being lit by the task-lighting device. The set of sensors and/or detectors also detect one or more of a luminescence, white-balancing, contrast, or the like, associated with the object that is being lit. Based on the detected information, the user-sensitive automatic task-lighting mechanism adjusts the lighting being provided by the task-lighting device. That is, the user-sensitive automatic task-lighting mechanism adjusts the light intensity or brightness provided by the task-lighting device to a preferred setting for the user that is using the object and thus, the task-lighting device that is lighting the object Thus, the user-sensitive automatic task-lighting mechanism provides an amount of light that is personalized to the person and/or task involved.
However, if object recognition engine 304 detects that object 322 is present, lighting conditions recognition engine 306 performs a set of operations to determine a light intensity associated with lighting object 322. For example, using lighting condition sensors 324 such as, for example, a luminosity or lux sensor, a contrast detection sensor, a white-balancing detection sensor, optical character recognition sensor, or the like, lighting conditions recognition engine 306 may determine the amount of light that is being displayed on object 322. If a set of user preference parameters 316 is not yet established, light intensity adjustment engine 308 utilizes default parameters 314 to adjust the amount of light being emitted by light-emitting device 318 to a level to achieve the task for which task-lighting device 300 is being utilized.
Once light intensity adjustment engine 308 adjusts the amount of light being emitted by light-emitting device 318, light intensity adjustment engine 308 may determine whether the user manually adjusts the amount of light being emitted by light-emitting device 318 to a user-preferred level. If the user manually adjusts the amount of light being emitted by light-emitting device 318, light intensity adjustment engine 308 stores the current parameters of lighting condition sensors 324 and the amount of light being emitted by light-emitting device 318 as user preference parameters 316. Then the next time light intensity adjustment engine 308 adjusts the amount of light being emitted by light-emitting device 318, light intensity adjustment engine 308 will utilize user preference parameters 316 to adjust the amount of light being emitted by light-emitting device 318. If the user does not make any adjustments to the amount of light being emitted by light-emitting device 318 based on default parameters 314 or after storing the current parameters as user preference parameters 316, object recognition engine 304 continues to detect changes in object 322 that is being lit by light-emitting device 318 of task-lighting device 300.
As a further embodiment, object recognition engine 304 may determine whether object 322 is changing from a first period to a second time period as well as a time interval between the first and second time periods, and facilitate a change in the amount of light being emitted by light-emitting device 318 through light intensity adjustment engine 308 if the interval is longer or shorter than a predetermined time interval threshold. For example, is a user reading a book has been turning pages every 5 minutes, but then next page turn takes 7 minutes, then object recognition engine 304 may send a signal to light intensity adjustment engine 308 to increase the lighting level as the pages may be harder for the user to read. As another example, if a user chopping vegetables was chopping at one speed but then slows down in their chopping, object recognition engine 304 may send a signal to light intensity adjustment engine 308 to increase the lighting level as the surface on which the vegetables are being chopped may be harder for the user to see. While the examples use an increase in the lighting level output by light-emitting device 318, the illustrative embodiment may recognize that a decrease in the lighting level output by light-emitting device 318 may be necessary in other instances without departing from the spirit and scope of the invention.
In order to determine a change in object 322 from a first period to a second time period as well as a time interval between the first and second time periods, object recognition engine 304 may capture a set of images utilizing image capture engine 326, each image having an associated time stamp. Object recognition engine 304 compares images and if there is no movement of the object in a first image as compared to the same object in a second image and the time interval between the time stamp of the first image and the time stamp of the second image is longer or shorter than the predetermined time interval threshold, then object recognition engine 304 signal light intensity adjustment engine 308 to adjust the amount of light being emitted by light-emitting device 318.
In order to exemplify the operations performed by user-sensitive automatic task-lighting mechanism 302, consider the following examples. In a first example, a user is reading a book and utilizes a reading lamp to light the pages of the book. The components of the user-sensitive automatic task-lighting mechanism 302 identify the book as the object for which the reading lamp is being utilized and detect reflected light as a basis for how much extra light is needed. The components of the user-sensitive automatic task-lighting mechanism 302 adjust its intensity of the light being emitted based on where the book is, because a person could change positions while sitting. That is, user-sensitive automatic task-lighting mechanism 302 may be equipped with both movement control mechanism 328 and aperture control mechanism 330. Thus, when a user changes position, such as leaning from a right side of a chair to a left side of a chair, when user-sensitive automatic task-lighting mechanism 302 detects such a movement of the book, movement control mechanism 328 repositions task-lighting device 300 such that the beam position is adjusted based on whether the book is. Similarly, user may move the book either closer or further away from a starting position. Thus, when user-sensitive automatic task-lighting mechanism 302 detects such a movement of the book, the beam of light emitted by light-emitting device 318 may need to be narrowed or widened. Therefore, aperture control mechanism 330 narrows or widens an aperture of task-lighting device 300 such that the beam of light emitted by light-emitting device 318 is narrowed or widened. Further, if the user puts down the book, then the user-sensitive automatic task-lighting mechanism 302 may turn task-lighting device 300 off or, utilizing voice detection mechanism 332, detect a conversation taking place and change the intensity of the beam of light emitted by light-emitting device 318 to an ambient lighting level to produce enough light to create a social atmosphere.
In another example, a user is looking in a vanity mirror that is surrounded by light bulbs. Since some people are taller than others, since some people stand closer to the mirror than others, and/or since some people's facial color is different than others, user-sensitive automatic task-lighting mechanism 302 may control each light bulb around the mirror at a different level so as to light the object, i.e. the user's face, so that, based on the position of the user's face, top light bulbs may be brighter than the bottom light bulbs in order to make the facial appearance better. In yet another example, a user is preparing a meal but more specifically is using a knife to prepare the vegetables for the meal. In this example, the knife, the vegetables, and the user's hands are the objects of concern. Depending to position of these objects, user-sensitive automatic task-lighting mechanism 302 increases or decreases the emitted light using reflected light on the knife, the vegetables, and the user's hands.
Thus, the user-sensitive automatic task-lighting mechanism 302 utilizes a set of sensors and/or detectors to determine an object that is being lit by the task-lighting device and detects one or more of a luminescence, white-balancing, contrast, or the like, associated with the object that is being lit. Based on the detected information, the user-sensitive automatic task-lighting mechanism 302 adjusts the light intensity or brightness provided by the task-lighting device to a user-preferred setting that is personalized to the person and/or task involved.
The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.
Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart, illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
If at step 404 the object recognition engine detects an object, a lighting conditions recognition engine of the user-sensitive automatic task-lighting mechanism performs a set of operations to determine a light intensity associated with lighting the object (step 408). For example, the lighting conditions recognition engine uses a set of lighting condition sensors such as, for example, a luminosity or lux sensor, a contrast detection sensor, a white-balancing detection sensor, optical character recognition sensor, or the like, to determine the amount of light that is being displayed on the object. Once the amount of light that is being displayed on the object is determined, a light intensity adjustment engine of the user-sensitive automatic task-lighting mechanism determines whether a set of user preference parameters has been established (step 410). If at step 410 the set of user preference parameters has not been set, then the light intensity adjustment engine utilizes default parameters to adjust the amount of light being emitted by the light-emitting device to a level to achieve the task for which the task-lighting device is being utilized (step 412).
Once the light intensity adjustment engine adjusts the amount of light being emitted by the light-emitting device using the default parameters, the light intensity adjustment engine determines whether the user manually adjusts the amount of light being emitted by the light-emitting device to a user-preferred level (step 414). If at step 414 the user manually adjusts the amount of light being emitted by the light-emitting device, the light intensity adjustment engine stores the current parameters of the lighting condition sensors and the amount of light being emitted by light-emitting device as user preference parameters (step 416), with the operation returning to step 402 thereafter. If at step 414 the user manually fails to adjust, the amount of light being emitted by the light-emitting device, the operation returns to step 402.
If at step 410 the set of user preference parameters have been set, then the light intensity adjustment engine utilizes the user preference parameters to adjust the amount of light being emitted by the light-emitting device to a level to achieve the task for which the task-lighting device is being utilized (step 418). Once the light intensity adjustment engine adjusts the amount of light being emitted by the light-emitting device using the user preference parameters, the light intensity adjustment engine determines whether the user manually adjusts the amount of light being emitted by the light-emitting device to a user-preferred level (step 420). If at step 420 the user manually adjusts the amount of light being emitted by the light-emitting device, the light intensity adjustment engine utilizes the current parameters of the lighting condition sensors and the amount of light being emitted by light-emitting device to update the user preference parameters (step 422), with the operation returning to step 402 thereafter. If at step 420 the user manually fails to adjust the amount of light being emitted by the light-emitting device, the operation returns to step 402.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or early out combinations of special purpose hardware and computer instructions.
Thus, the illustrative embodiments provide mechanisms for automatically providing a user-sensitive amount of light for a specific task. The user-sensitive automatic task lighting mechanism detects an object for which task lighting is being utilized and uses feedback, such as luminescence, white-balancing, contrast, or the like, to adjust the amount of light that is being provided by the task-lighting device to light the object. Utilizing a default and/or personalized lighting preferences, the user-sensitive automatic task-lighting mechanism adjusts the lighting behavior provided by the task-lighting device to a comfortable, personalized level to achieve the task being performed by the associated user.

The memory may be of various types including, but not limited to, ROM, PROM, EPROM, EEPROM, DRAM, SRAM, Flash memory, solid state memory, and the like.
Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, etc.) can be coupled to the system either directly or through intervening wired or wireless I/O interfaces and/or controllers, or the like. I/O devices may take many different forms other than conventional keyboards, displays, pointing devices, and the like, such as for example communication devices coupled through wired or wireless connections including, but not limited to, smart phones, tablet computers, touch screen devices, voice recognition devices, and the like.
