Description

BACKGROUND

The variety of configurations of computing devices is ever increasing. For example, computing devices may be found in an ever increasing variety of form factors, such as from traditional personal computers to game consoles and mobile communications devices such as tablets, smartphones, portable game devices, and so on.

Additionally, the functionality that is made available by each of these devices is also ever increasing. For example, productivity applications such as spreadsheets and word processors have expanded from traditional personal computers to tablets, gaming applications have expanded from dedicated game consoles to mobile computing devices, and so forth. However, these different uses may encounter complications when used on computing devices having configurations that were not originally designed for those uses.

SUMMARY

Input device configurations are described. In one or more implementations, an input device includes a connection portion, protective case, and one or more controls. The connection portion is configured to provide a removable physical connection to a computing device. The protective case is coupled to the connection portion and configured to support rotational movement of the protective case in relation to the computing device when the connection portion is physically connected to the computing device. The one or more controls are disposed on the protective case such that at least one control is accessible to a user when the protective case is positioned behind the computing device and the computing device and the input device are grasped by one or more hands of a user.

In one or more additional implementations, an apparatus includes a protective case configured to at least partially encompass a housing of a computing device. One or more controls are disposed on a surface of the protective case and configured to provide one or more inputs to the computing device. At least one of the controls is positioned to be accessible by a thumb of a user's hand when holding the protective case having the computing device disposed therein and positioned on a side of the protective case that corresponds to a display device of the computing device.

In one or more implementations, an input device is rotated to assume a first position in relation to a computing device, the input device removably connected to the computing device using magnetism, the first position causing a protection portion of the input device to substantially cover a display device of the computing device. The input device is also rotated to assume a second position in relation to the computing device, the second position causing the protection portion to be disposed at a rear of a housing of the computing device that is opposite to the display device and exposure of at least one control that is configured to provide one or more inputs to the computing device.

DETAILED DESCRIPTION

Overview

As previously described, computing devices may assume a variety of configurations and be employed for a variety of different uses. However, some of these configurations were conventionally less suited for some uses than other configurations. For example, conventional gaming devices employed dedicated hardware gaming controllers via which a user could interact with the game. These controllers typically included hardware configured to support intuitive interaction with a game. As games continued to expand to mobile communications devices such as tablets and mobile phones, however, limitations encountered through use of a touchscreen as the sole input device could limit a user's interaction with the games, especially when compared with dedicated devices.

Input device configurations are described. In one or more implementations, an input device is designed for use with a computing device such as mobile communications device having a slate form factor, e.g., a mobile phone, tablet, and so on. The input device may assume a variety of configurations to expand the functionality of the computing device.

For example, the input device may be configured as part of a protective cover for a mobile communications device that assumes a slate form factor, e.g., mobile phone, tablet, and so on. The protective cover may include one or more controls that are disposed on a surface of the protective cover to initiate functions of the computing device. Additionally, these controls may be arranged such that the controls are accessible while a user is grasping the device using one or more hands. In this way, a user may be provided with an expanded range of functionality for these device configurations.

The protective cover may be configured in a variety of ways. For instance, the protective cover may be configured as a shell that substantially encompasses the display device. In another example, the protective cover may be configured to be removably coupled to the computing device, such as through use of one or more magnets. Accordingly, the protective cover may be rotated to cover a display device of the computing device or be rotated for positioning at a rear of the computing device, such as to enable a user to view the display device.

When positioned at the rear of the computing device, the protective cover may be configured such that one or more controls are made available for interaction with the computing device. Continuing with the previous example, a user may grasp the computing device and operate the controls positioned at a front of the protective cover using their thumbs, controls positioned at the rear of the protective cover using their fingers, and so on. In this way, a user may grasp and hold the device and yet have access to controls that may be utilized to interact with the device, such as controls to interact with a game. A variety of other configurations are also contemplated, including configurations that do not involve games, further discussion of which may be found in relation to the following sections.

In the following discussion, an example environment is first described that may employ the techniques described herein. Example procedures are then described which may be performed in the example environment as well as other environments. Consequently, performance of the example procedures is not limited to the example environment and the example environment is not limited to performance of the example procedures.

Example Environment

FIG. 1 is an illustration of an environment 100 in an example implementation that is operable to employ the techniques described herein. The illustrated environment 100 includes an example of a computing device 102 having an input device 104 that is communicatively and physically attached to the computing device 102.

The computing device 102 may be configured in a variety of ways. For example, the computing device 102 may be configured for mobile use (e.g., handheld), such as in a slate configuration. Examples of slate configurations may be found in mobile phones, a tablet computer as illustrated, portable game devices, music players, and so on. Thus, the computing device 102 may range from full resource devices with substantial memory and processor resources to a low-resource device with limited memory and/or processing resources.

The computing device 102 and the input device 104 are illustrated as being grasped in the hands 106, 108 of a user. Thus, as illustrated the thumbs of the user's hands 106, 108 are positioned to interact with a front surface of the input device 104 and computing device 102 that includes a display device 110 of the computing device 102. The display device 110, for instance, may include touchscreen functionality that is configured to detect proximity of an object (e.g., one or more fingers of the user's hands 106, 108) to interact with a user interface displayed by the display device 110.

The input device 104 may also be configured to support interaction in this scenario. In the illustrated example, the input device 104 includes control portions 112, 114 that are configured to be disposed at a front of the computing device 102, e.g., to be viewable simultaneously with the display device 110. In the illustrated example, the control portions 112, 114 of the input device 104 include controls that are configured for interaction with the thumbs of the user's hands 106, 108 while grasping the computing device 102 and the input device 104. Other controls may also be included on a back of the input device 104 as further described in the below discussion. In one or more implementations, the controls 112, 114 may be configured to support feedback such as haptics.

The illustrated configuration shows a close proximity between the display device 110 of the computing device 102 and controls 116 of the input device 104. As previously stated, the display device 110 may also support touch functionality. Therefore, a user may interact with a user interface output by the display device 110 and controls 116 of the input device 104 in an efficient manner due to this close proximity.

In the illustrated example, the controls are configured for use in conjunction with a game. As such, the controls may be configured to mimic controls found on a game controller. Other configurations are also contemplated, however, as further described in relation to FIG. 9. The input device 104 may assume a variety of different configurations, an example of which is described as follows and shown in a corresponding figure.

FIG. 2 depicts an example of a system 200 in which the input device 104 is configured as a protective shell. The system 200 of FIG. 2 includes the computing device 102 that assumes a slate configuration as described in relation to FIG. 1. The input device 104 is configured as a protective case configured as a shell 202 that is configured to at least partially encompass a housing of the computing device 102. For example, the input device may be configured to cover a back, sides, and bezel of the computing device 102 and yet include an opening via which a user may view the display device 110 of the computing device 102.

The shell 202 may be configured in a variety of ways for assembly around the computing device 102. The shell 202, for instance, may include a slot 204 via which the computing device 102 is slid through. In another instance, the protective shell 202 may be configured to “snap together” from two or more separate parts around a housing of the computing device 102. A variety of other configurations are also contemplated, such as through configuration as part of a cover of the computing device 102, an example of which is described as follows and shown in a corresponding figure.

FIG. 3 depicts a system 300 in an example implementation in which the input device 104 is configured as a cover for use with the computing device 102. The input device 104 in this example is removably attached to the computing device 102, which may be accomplished in a variety of ways as described in relation to FIG. 8. The input device 104 in this example includes a flexible hinge 302 via which the input device 104 and the computing device 102 may rotate in relation to each other.

The flexible hinge 302 is flexible in that rotational movement supported by the hinge is achieved through flexing (e.g., bending) of the material forming the hinge as opposed to mechanical rotation as supported by a pin, although that embodiment is also contemplated. Further, this flexible rotation may be configured to support movement in one or more directions (e.g., vertically in the figure) yet restrict movement in other directions, such as lateral movement of the input device 104 in relation to the computing device 102. This may be used to support consistent alignment of the input device 104 in relation to the computing device 102, such as to align sensors used to change power states, application states, and so on.

This rotational movement may result in different orientations of the input device 104 in relation to the computing device 104. These different orientations may be detected using sensors of the computing device 104 and/or input device 104, such as accelerometers, magnetometers, inertial measurement units, gyroscopes, Hall Effect sensors, and so on. The detected orientations may then be used to change a state of the computing device 102 (e.g., applications executed by the device) and/or the input device 104.

Opening of the input device 104 from a closed orientation to an open orientation as shown in FIG. 4, for instance, may cause an application (e.g., game) to resume a previous state at which point at which the input device 104 and the computing device 102 were “closed.” Closing of the input device 104 may further cause a history to be deleted or saved. In another example, resuming of the open configuration may cause the application and input device 104 to enter a play mode for output of media. For example, the play mode may cause reconfiguration of a user interface output on the display device (e.g., resizing) such that portions of the display device 110 covered by the control portions are not used to display the UI. The flexible hinge 106 may be configured to support this movement in a variety of ways, further discussion of which follows.

The flexible hinge 106, for instance, may be formed using one or more layers of fabric and include conductors formed as flexible traces to communicatively couple the input device 104 to the computing device 102 and vice versa. This communication, for instance, may be used to communicate a result of a key press to the computing device 102, receive power from the computing device, perform authentication, provide supplemental power to the computing device 102, and so on. The flexible hinge 106 may be configured in a variety of ways, further discussion of which may be found in relation to FIG. 8.

The input device 104 is illustrated as including an input portion 304. The input portion in this example includes a keyboard having a QWERTY arrangement of keys and track pad although other arrangements of keys are also contemplated. Thus, the input device 104 and keys incorporated by the input device 104 may assume a variety of different configurations to support a variety of different functionality. For example, the input device 104 may be configured to assume a form factor of a thickness of one millimeter or less, e.g., 0.65 millimeters. This may be performed in a variety of ways, such as through use of pressure sensitive switches that include a flexible contact layer having a force sensitive ink configured to contact shunts to initiate inputs. In another example, triggers may be employed that support a tactile experience (e.g., through a mechanical spring or foam) to provide tactile feedback, e.g., such as in an implementation employing a thickness of four millimeters or less. These techniques may be employed for the keys of the input device 104 and controls 116, including controls that may be disposed at a rear of the device as shown in FIG. 4.

The input device 104 is further illustrated as including control portions 112, 114 that are attached to the input portion 304 to support rotation movement, which are illustrated in phantom in this instance. The control portions 112, 114 include the controls 116 as previously described that are configured to initiate operations of the computing device 102, such as to provide interaction in a game or other application. The controls 116, for instance, may be configured to support pressure sensitivity, such as through use of force-sensitive inks and shunt geometries as described above.

Thus, in this example the input portion 304 of the input device 104 may be rotated behind the computing device, e.g., at a rear portion of the computing device 102 that opposes the display device 110. When in such a configuration, the control portions 112, 114 may each be rotated over a respective side of the housing of the computing device 102 to assume the configuration as shown in FIG. 1. Therefore, when in such a configuration the computing device 102 and the input device 104 may be grasped and supported by one or more hands 106, 108 of the user.

Further, the controls 116 of the input device 104 are accessible to the user for interaction with the computing device 102. In this way, a portable configuration may be supported for use with a slate computer yet still provide increased functionality of dedicated hardware controls 116. In one or more implementations, the control portions 112, 114 may be removably secured to the computing device 102. For example, the computing device 102 and/or the control portions 112, 114 may include magnets such that when the control portions 112, 114 are “flipped” onto the front of the computing device, these portions “snap” onto the device. This may promote an improved look and feel when interacting with these portions.

FIG. 4 depicts an example of a top view 400 of the computing device 102 and input device when assuming the configuration as shown in FIG. 1. As shown, the input portion 304 is positioned at a rear of the computing device 102. The control portions 112, 114 are then rotated around the sides of the computing device 102 to coincide with the display device 110. In this way, controls included on the control portions 114, 112 may also be viewed and interacted with when in this configuration.

Further, rear controls 402 may also be made assessable by the input device 104. This may include use of dedicated controls to provide operations such as triggers that are found on game controllers. In another example, keys of the input portion 304 may be repurposed. For instance, one or more the keys of the QWERTY keyboard may be accessed by fingers of the user's hands 106, 108 when grasping the input device 104. Thus, in one or more implementations a portion of the keys of the input portion 304 may be disabled when in this configuration (e.g., keys located in a center of the input portion 304 such as letter keys) with another portion of the keys used to support interaction when grasping and supporting the input device 104, e.g., shift, backspace, tab, and so on, such as when in a game mode as described above.

FIG. 5 depicts a side view 500 of the input device 104 of FIG. 3 as covering a display device 110 of the computing device 102. In this example, the input portion 304 is rotated to substantially cover the display device 110 of the computing device 102. This may be performed in a variety of ways, such as through use of the flexible hinge 302 and a connection portion 502 that is configured to removably connect the input device 104 to the computing device 102, e.g., through magnetism. The control portions 112, 114 may be positioned in a variety of ways to support this arrange.

FIG. 6, for instance, depicts an example of top view 600 of the input device 104 of FIG. 5 in which the control portions 112, 114 are positioned at a rear of the computing device 102. Like FIG. 4, the control portions 112, 114 may be rotated around the sides of the computing device 102. In this example, however, the control portions 112, 114 are positioned at a rear of the computing device 102. Further, the control portions 112, 114 may also be secured in this configuration, such as through use of magnets or other retention devices.

FIG. 7 depicts another instance of a top view 700 of the input device 104 of FIG. 5. In this example, the control portions 112, 114 are positioned over the input portion 304 when covering the display device 110. Accordingly, the input portion 304 covers the display device 110 and the control portions 112, 114 are positioned such that the input portion 304 is located between the display device 110 and the control portions 112, 114. A variety of other examples are also contemplated without departing from the spirit and scope thereof.

FIG. 8 depicts an example implementation 800 of the input device 104 of FIG. 3 as showing the flexible hinge 302 in greater detail. In this example, a connection portion 802 of the input device 104 is shown that is configured to provide a communicative and physical connection between the input device 104 and the computing device 102. The connection portion 802 as illustrated has a height and cross section configured to be received in a channel in the housing of the computing device 102, although this arrangement may also be reversed without departing from the spirit and scope thereof.

The connection portion 802 is flexibly connected to the input portion 304 of the input device 104 that includes the keys through use of the flexible hinge 302. Thus, when the connection portion 802 is physically connected to the computing device the combination of the connection portion 802 and the flexible hinge 302 supports movement of the input device 104 in relation to the computing device 102 that is similar to a hinge of a book.

Through this rotational movement, a variety of different orientations of the input device 104 in relation to the computing device 102 may be supported as previously describe. For example, rotational movement may be supported by the flexible hinge 106 such that the input device 104 may be placed against the display device 110 of the computing device 102 and thereby act as a cover as shown in the example orientation of FIG. 5. Thus, the input device 104 may act to protect the display device 110 of the computing device 102 from harm.

As shown in the example orientation of FIG. 3, a typing arrangement may be supported. In this orientation, the input device 104 is laid flat against a surface and the computing device 102 is disposed at an angle to permit viewing of the display device 110, e.g., such as through use of a kickstand disposed on a rear surface of the computing device 102.

In the example orientation of FIG. 4, the input device 104 may also be rotated so as to be disposed against a back of the computing device 102, e.g., against a rear housing of the computing device 102 that is disposed opposite the display device 110 on the computing device 102. In this example, through orientation of the connection portion 802 to the computing device 102, the flexible hinge 106 is caused to “wrap around” the connection portion 202 to position the input device 104 at the rear of the computing device 102. Thus, in this orientation the user may access touchscreen functionality of the display device 110 from a front of the device and keys of the input device 104 from a rear of the device.

Naturally, a variety of other orientations are also supported. For instance, the computing device 102 and input device 104 may assume an arrangement such that both are laid flat against a surface as shown in FIG. 1. Other instances are also contemplated, such as a tripod arrangement, meeting arrangement, presentation arrangement, and so forth.

Returning again to FIG. 8, the connection portion 802 is illustrated in this example as including magnetic coupling devices 804, 806, mechanical coupling protrusions 808, 810, and a plurality of communication contacts 812. The magnetic coupling devices 804, 806 are configured to magnetically couple to complementary magnetic coupling devices of the computing device 102 through use of one or more magnets. In this way, the input device 104 may be physically secured to the computing device 102 through use of magnetic attraction. The connection portion 802 also includes mechanical coupling protrusions 808, 810 to form a mechanical physical connection between the input device 104 and the computing device 102.

The mechanical coupling protrusions 808, 810 are configured to be received within complimentary cavities within a channel of the computing device 102. When so received, the mechanical coupling protrusions 808, 810 promote a mechanical binding between the devices when forces are applied that are not aligned with an axis that is defined as correspond to the height of the protrusions and the depth of the cavity.

The connection portion 802 is also illustrated as including a plurality of communication contacts 812. The plurality of communication contacts 812 is configured to contact corresponding communication contacts of the computing device 102 to form a communicative coupling between the devices. Although a physical communicative coupling is illustrated, wireless implementations are also contemplated without departing from the spirit and scope thereof. The input device 104, for instance, may include a battery and wireless communication system to support wireless communication between the devices. In the previous examples, the input device 104 is illustrated as configured for use with a game. Other implementations are also contemplated, an example of which is described and follows and shown in a corresponding figure.

FIG. 9 depicts a system 900 in an example implementation in which another configuration of the input device 104 is shown. In this example, the input device 104 is also communicatively coupled to the computing device 102 and configured to act as a cover similar to the input device 104 of FIG. 3.

In this example, however, a single control portion 902 is configured to extend around a side of the computing device 102. The control portion 902 includes controls that are configured for use in navigating through a presentation. As such, the computing device 102 may display sides involved in the presentation in a user interface which may be selected using one or more fingers of the user's hand 108. Additionally, the controls 904 may be operated with a thumb of the user's other hand 106. A variety of other configurations and controls are also contemplated, such as to include controls configured for use in a browser to surf the Internet, controls configured to support interaction with a social network, and so forth.

Example Procedures

The following discussion describes input device techniques that may be implemented utilizing the previously described systems and devices. Aspects of each of the procedures may be implemented in hardware, firmware, or software, or a combination thereof. The procedures are shown as a set of blocks that specify operations performed by one or more devices and are not necessarily limited to the orders shown for performing the operations by the respective blocks. In portions of the following discussion, reference will be made to FIGS. 1-9.

FIG. 10 depicts a procedure 1000 in an example implementation in which the input device assumes different positions relative to a computing device. An input device is rotated to assume a first position in relation to a computing device, the input device removably connected to the computing device using magnetism, the first position causing a protection portion of the input device to substantially cover a display device of the computing device (block 1002). As shown in FIGS. 5, 6, and 7, for instance, the input portion 304 may act as a protection portion to protect the display device 110. As should be readily apparent, this may also be performed with a “plain” protection portion that does not include keys.

The input device is also rotated to assume a second position in relation to the computing device, the second position causing the protection portion to be disposed at a rear of a housing of the computing device that is opposite to the display device and exposure of at least one control that is configured to provide one or more inputs to the computing device (block 1004). As shown in FIGS. 1 and 4, for instance, the input portion 304 may be disposed at a rear of the computing device 102 yet still remain physically and communicatively coupled to the computing device 102. Control portions 112, 114 may then be used to expose controls 116 with which interaction may be performed using the thumbs of the user's hands 106, 108. A variety of other examples are also contemplated.

Example System and Device

FIG. 11 illustrates an example system generally at 1100 that includes an example computing device 1102 that is representative of one or more computing systems and/or devices that may implement the various techniques described herein. The computing device 1102 may be, for example, be configured to assume a hand held configuration through use of a housing formed and size to be grasped and carried by one or more hands of a user, illustrated examples of which include a mobile phone, mobile game and media device, and tablet computer although other examples are also contemplated.

The example computing device 1102 as illustrated includes a processing system 1104, one or more computer-readable media 1106, and one or more I/O interface 1108 that are communicatively coupled, one to another. Although not shown, the computing device 1102 may further include a system bus or other data and command transfer system that couples the various components, one to another. A system bus can include any one or combination of different bus structures, such as a memory bus or memory controller, a peripheral bus, a universal serial bus, and/or a processor or local bus that utilizes any of a variety of bus architectures. A variety of other examples are also contemplated, such as control and data lines.

The processing system 1104 is representative of functionality to perform one or more operations using hardware. Accordingly, the processing system 1104 is illustrated as including hardware element 1110 that may be configured as processors, functional blocks, and so forth. This may include implementation in hardware as an application specific integrated circuit or other logic device formed using one or more semiconductors. The hardware elements 1110 are not limited by the materials from which they are formed or the processing mechanisms employed therein. For example, processors may be comprised of semiconductor(s) and/or transistors (e.g., electronic integrated circuits (ICs)). In such a context, processor-executable instructions may be electronically-executable instructions.

The computer-readable storage media 1106 is illustrated as including memory/storage 1112. The memory/storage 1112 represents memory/storage capacity associated with one or more computer-readable media. The memory/storage component 1112 may include volatile media (such as random access memory (RAM)) and/or nonvolatile media (such as read only memory (ROM), Flash memory, optical disks, magnetic disks, and so forth). The memory/storage component 1112 may include fixed media (e.g., RAM, ROM, a fixed hard drive, and so on) as well as removable media (e.g., Flash memory, a removable hard drive, an optical disc, and so forth). The computer-readable media 1106 may be configured in a variety of other ways as further described below.

Input/output interface(s) 1108 are representative of functionality to allow a user to enter commands and information to computing device 1102, and also allow information to be presented to the user and/or other components or devices using various input/output devices. Examples of input devices include a keyboard, a cursor control device (e.g., a mouse), a microphone, a scanner, touch functionality (e.g., capacitive or other sensors that are configured to detect physical touch), a camera (e.g., which may employ visible or non-visible wavelengths such as infrared frequencies to recognize movement as gestures that do not involve touch), and so forth. Examples of output devices include a display device (e.g., a monitor or projector), speakers, a printer, a network card, tactile-response device, and so forth. Thus, the computing device 1102 may be configured in a variety of ways to support user interaction.

The computing device 1102 is further illustrated as being communicatively and physically coupled to an input device 1114 that is physically and communicatively removable from the computing device 1102. In this way, a variety of different input devices may be coupled to the computing device 1102 having a wide variety of configurations to support a wide variety of functionality. In this example, the input device 1114 includes one or more keys 1116, which may be configured as pressure sensitive keys, mechanically switched keys, and so forth.

The input device 1114 is further illustrated as include one or more modules 1118 that may be configured to support a variety of functionality.

Various techniques may be described herein in the general context of software, hardware elements, or program modules. Generally, such modules include routines, programs, objects, elements, components, data structures, and so forth that perform particular tasks or implement particular abstract data types. The terms “module,” “functionality,” and “component” as used herein generally represent software, firmware, hardware, or a combination thereof. The features of the techniques described herein are platform-independent, meaning that the techniques may be implemented on a variety of commercial computing platforms having a variety of processors.

An implementation of the described modules and techniques may be stored on or transmitted across some form of computer-readable media. The computer-readable media may include a variety of media that may be accessed by the computing device 1102. By way of example, and not limitation, computer-readable media may include “computer-readable storage media” and “computer-readable signal media.”

“Computer-readable storage media” may refer to media and/or devices that enable persistent and/or non-transitory storage of information in contrast to mere signal transmission, carrier waves, or signals per se. Thus, computer-readable storage media refers to non-signal bearing media. The computer-readable storage media includes hardware such as volatile and non-volatile, removable and non-removable media and/or storage devices implemented in a method or technology suitable for storage of information such as computer readable instructions, data structures, program modules, logic elements/circuits, or other data. Examples of computer-readable storage media may include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, hard disks, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other storage device, tangible media, or article of manufacture suitable to store the desired information and which may be accessed by a computer.

“Computer-readable signal media” may refer to a signal-bearing medium that is configured to transmit instructions to the hardware of the computing device 1102, such as via a network. Signal media typically may embody computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as carrier waves, data signals, or other transport mechanism. Signal media also include any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared, and other wireless media.

As previously described, hardware elements 1110 and computer-readable media 1106 are representative of modules, programmable device logic and/or fixed device logic implemented in a hardware form that may be employed in some embodiments to implement at least some aspects of the techniques described herein, such as to perform one or more instructions. Hardware may include components of an integrated circuit or on-chip system, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a complex programmable logic device (CPLD), and other implementations in silicon or other hardware. In this context, hardware may operate as a processing device that performs program tasks defined by instructions and/or logic embodied by the hardware as well as a hardware utilized to store instructions for execution, e.g., the computer-readable storage media described previously.

Combinations of the foregoing may also be employed to implement various techniques described herein. Accordingly, software, hardware, or executable modules may be implemented as one or more instructions and/or logic embodied on some form of computer-readable storage media and/or by one or more hardware elements 1110. The computing device 1102 may be configured to implement particular instructions and/or functions corresponding to the software and/or hardware modules. Accordingly, implementation of a module that is executable by the computing device 1102 as software may be achieved at least partially in hardware, e.g., through use of computer-readable storage media and/or hardware elements 1110 of the processing system 1104. The instructions and/or functions may be executable/operable by one or more articles of manufacture (for example, one or more computing devices 1102 and/or processing systems 1104) to implement techniques, modules, and examples described herein.
