Description

BACKGROUND
• Many peripheral devices include both inputs and outputs that are not associated with each other. An application instantiated on a computing system coupled to the peripheral devices may not have access to the association of the input and the output of the peripheral device.
SUMMARY
• Implementations described and claimed herein address the foregoing problems by allowing for association of an output of a peripheral device with an input of that peripheral device in a computing system. The association of the output with the input of the peripheral device provides an ability to link the associated input and output of the peripheral device in a computing system. An application instantiated on the computing system may use the association of the input and output capabilities of the peripheral device.
• In one implementation, for example, descriptor information of a peripheral device is received from a coupled peripheral device. The descriptor information describes attributes of the peripheral device and an association between an input of the peripheral device and an output of the peripheral device. Peripheral device classes of associated input attributes including associated output attributes of the peripheral device are provided and an instantiated application is informed of attributes of the peripheral device through classes.
• In another implementation, an interface layer is provided comprising associated input attributes and output attributes of an associated device. An input logical layer is used to access attributes of an interface layer for an input of the peripheral device including associated output attributes of the peripheral device. An attribute associated with the peripheral device is selected and set.
• In yet another implementation, for example, descriptor information of a peripheral device is received and used to build interface sets including attributes of an input and an associated output of the peripheral device. The interface sets may be used to select and set attributes of the peripheral device.
• In some implementations, articles of manufacture are provided as computer program products. One implementation of a computer program product provides a computer program storage medium readable by a computer system and encoding a computer program. Another implementation of a computer program product may be provided in a computer data signal embodied in a carrier wave by a computing system and encoding the computer program. Other implementations are also described and recited herein.
• This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Other features, details, utilities, and advantages of the claimed subject matter will be apparent from the following more particular written Detailed Description of various embodiments and implementations as further illustrated in the accompanying drawings and defined in the appended claims.

DETAILED DESCRIPTION
• A computing system for associating an output of a peripheral device with an input of that peripheral device is provided.
• FIG. 1 depicts anexample computing system100 that associates output capabilities of aperipheral device102 with input attributes of thatperipheral device102. Thecomputing system100 is coupled to at least oneperipheral device102. Theperipheral device102 comprises at least one input capability and at least one output capability that can be associated with that input capability.
• Theperipheral device102 may comprise any type of peripheral device that may be coupled to thecomputing system100. Theperipheral device102 may comprise, for example, a typical peripheral input device for a desktop or laptop computer, such as a keyboard, a mouse, a joystick, a game controller, a tablet screen, a web camera, a microphone, an external storage device, or other computer input/output peripheral device. Theperipheral device102 may also comprise a peripheral device to any other type of computing system, such as a mobile telephone, a security system, a vehicle or airplane control system, or any other type of computing system. Theperipheral device102 may, for example, comprise a peripheral device to an automobile computing system, such as an identification (e.g., bio-identification or keypad) module, an entry door handle, a button, a touch pad or screen, or any other type of peripheral device that may be coupled to and controlled by thecomputing system100.
• Theperipheral device102 may be coupled to thecomputing system100 in any manner, such as via a wired orwireless link104. Theperipheral device102 may be integral with the computing system100 (e.g., a laptop computer or mobile telephone keyboard) or removably coupled to thecomputing system100 via a wireless or wired connection (e.g., an IEEE 802.11 wireless peripheral device, a Bluetooth wireless peripheral device, a radio frequency wireless peripheral device, a serial peripheral device, a universal serial bus (USB) peripheral device (e.g., a human interface device (HID) such as a keyboard, a mouse, or a joy stick), a camera, an external storage device, a microphone, or the like).
• Aperipheral device102 may include any number of inputs associated with any number of outputs on theperipheral device102. A keyboard peripheral device, for example, may comprise a number of input keys (e.g., a QWERTY, Dvorak, T-9 or other keyboard) that may be associated with any number of outputs that may be controlled by thecomputing system100 under the control of the inputlogical layer110. One or more outputs of the keyboard may be associated with an input of the keyboard.
• In one implementation, for example, a height of a particular key or group of keys may be raised or lowered to raise or lower their profile relative to other keys on the keyboard. On a locked mobile telephone keyboard, for example, keys used to unlock the keyboard may be lowered to reduce the chance of having the keys inadvertently pressed. In another implementation, as one or more modifier keys (e.g., “CTRL,” “ALT,” “FN,” “ALTGR,” or other modifier keys) are pressed, keys that correspond to that particular key may be raised in height and/or keys that do not correspond to a particular modifier key may be lowered in height to indicate which keys are expected to be depressed.
• One or more displays on the peripheral device may also be used to indicate current settings, likely keystroke combinations, or other information. Displays on a keyboard may show current settings for the keyboard (e.g., fonts, colors, uppercase, lowercase). The displays may be located on individual keys of the keyboard or on another portion of the display. Similar to key height outputs described above, the displays may also be used to indicate likely keystrokes (e.g., when a modifier key has been depressed or where an application predicts likely keystroke combinations) or other settings (e.g., a “key lock-out” feature that prevents repetitive otherwise unwanted keystroke combinations).
• Other peripheral devices may also include any number of outputs that may be associated with an input of the device. On a mouse, for example, a button of the mouse may be raised when a cursor controlled by the mouse is over a link that may be selected by use of that button and/or lowered when the cursor is not over such a link.
• An access peripheral device (e.g., a door handle of an automobile or a secured doorway) may be controlled to allow access by controlling one or more output of the peripheral device. When a user is deemed to be an authorized user, a door handle or other access peripheral device, may be controlled to allow access. A door handle may be retracted when access is to be prevented and/or extended to an accessible position when access is permitted. In another implementation, a temperature of a button for a climate control system (e.g., on a house thermostat or an automobile climate control system) may be controlled to indicate to a user if it will increase or decrease a temperature set point of the climate control system.
• An input and/or an output of theperipheral device102 may be static or dynamic. A static input or output, for example, may comprise an input or output that is used for a single purpose, while a dynamic input or output may change functions depending upon one or more conditions of thecomputing system100. A dynamic button in an automobile computing system, for example, may be used to initiate ignition of an engine when the automobile is off, while the same button may be used to control some other aspect of the automobile computing system when the engine is running. Similarly, a dynamic output associated with the button may be changed corresponding to the function of the input button at any given time.
• These implementations of outputs that may be associated with an input of a peripheral device are merely examples. One skilled in the art would readily appreciate from this disclosure that any number of other types of peripheral devices may include any number of types of outputs that may be associated with one or more type of input of a peripheral device.
• Theperipheral device102 is self-aware in that it comprises self-identifier configuration information106 that may be used by thecomputing system100 to associate an output capability of theperipheral device102 with an input capability of theperipheral device102. Theperipheral device102 is coupled to thecomputing system100 via coupling hardware108 (e.g., a port associated with thecomputing system100, such as a serial port, a USB port, a parallel port, a wireless transceiver, or the like).
• The self-identifier configuration information106 may comprise, for example, a logical association between the output capability and the input capability of theperipheral device102, physical attributes of the output or input device (e.g., a screen size, color capabilities, placement capabilities, movement capabilities, or other attributes).
• An inputlogical layer110 is provided in thecomputing system100 for associating an output of theperipheral device102 with an input of that peripheral device. The inputlogical layer110 provides unified access to and control of different elements of theperipheral device102 to an operating system running on thecomputing system100. Where a keyboard peripheral device comprises a number of inputs and corresponding outputs, for example, the inputlogical layer110 may provide an interface for accessing and controlling the inputs and outputs of the keyboard peripheral device.
• In one implementation, for example, the input logical layer may link separate logical representations of devices, such as device classes or other representations. In the implementation shown inFIG. 1, for example, thecomputing system100 comprises device classes for akeyboard112, amouse114, and adoor handle116. In addition, for each class, thecomputing system100 further comprises aninterface set118,120, and122 (e.g., an interface layer) including attributes for the corresponding device class. The interface set may comprise, for example, an application programming interface (API) set that includes attributes for the corresponding device class. API sets are just one example of an interface set that may be used. Other types of interface sets may also be used.
• The inputlogical layer110 may receive the self-identifier configuration information106 from theperipheral device102 and create the logical representations for theperipheral device102. The inputlogical layer110, for example, may receive a peripheral device class and configuration information identifying one or more inputs and outputs of theperipheral device102 and generate an interface associating at least one output with an input of theperipheral device102.
• FIG. 2 depicts anexample data structure200 of an input logical layer for a human interface device (HID) peripheral device that may be used with a computing system for associating output capabilities of a peripheral device with input attributes of that peripheral device. As shown inFIG. 2, theexample data structure200 comprises logical collections for peripheral devices associating inputs and outputs of the peripheral devices. In the implementation shown inFIG. 2, thedata structure200 comprises a logical collection for each input of the peripheral device. A logical collection for a keyboard input “a”202, for example, comprises an input identifier together with example outputs that may be associated with that input. In this example, thelogical collection202 corresponding to an input “a” comprises output identifiers corresponding to a “Display,” a “Height,” and a “Temperature.” Other output identifiers are of course possible. A physical location of the input and/or each associated output may also be provided, such as shown inFIG. 2.
• In this implementation, the input logical layer may utilize thedata structure200 to identify and control one or more outputs corresponding to a particular input of a peripheral device coupled to a computer system. An application may, for example, utilize the logical input layer to control an output on the peripheral device corresponding to a particular input of the peripheral device. An application running on a computing system may, for example, direct the input logical layer to alter a height, temperature, and/or a display associated with an input key “a” of the keyboard peripheral device.
• Thedata structure200 shown inFIG. 2, however, is merely one example of a data structure that may be used. Other data structures, such as an XML schema data structure, may also be used.
• FIG. 3 depicts anexample process300 for associating an output of a peripheral device with an input of that peripheral device in a computing system. In theprocess300, a peripheral device comprising at least one input and at least one output is coupled to the computing system inoperation302. The computing system reads a descriptor for each input and output of the peripheral device inoperation304. The descriptor may, for example, include the capability of each input and output and may further include attributes (e.g., a static or dynamic attribute) for each input and output of the peripheral device. An input logical layer of the computing system separates logical representations of a class or other the top level of a peripheral device (e.g., a keyboard, a mouse, a joy stick, a door handle, or the like) inoperation306. The input logical layer can also build an interface set (e.g., an API layer) associated with each class of the peripheral device inoperation308.Operations302,304,306, and308 may comprise a set-up operation that may or may not be repeated in subsequent operations after the peripheral device has previously been coupled to the computing system.
• Depending on the class or other logical designation of the peripheral device, the input logical layer of the computing system may call the set attribute API of an input attribute logical layer inoperation310. The input logical layer may also determine an attribute associated with an input report inoperation312. The input logical layer may also set an attribute of the peripheral device inoperation314. In one implementation, for example, the input logical layer may send information over a bus, may send a state change request to a cache or other data storage held in the peripheral device, send state information to the peripheral device to prepopulate the cache or other data storage of the peripheral device for a specific application, or set an attribute of the peripheral device via another method. In some various implementations, for example, a keyboard peripheral device may be set for various math sets, music sets, symbol translations for foreign languages and outputs of the keyboard peripheral device may be used to identify the variations of the inputs of the keyboard. The individual keys of the keyboard peripheral device may each comprise a display that may be altered to display various math sets, music sets, or language sets that could be used with the keyboard peripheral device.
• One or more output of a peripheral device may be associated with an input of that peripheral device. In one example, a keyboard modifier key (e.g., “CTRL,” “ALT,” “FN,” “ALTGR,” or other modifier keys) may be associated with outputs identifying acceptable keys of a limited entry set that may correspond to a latched modifier key. The limited entry set, for example, may include keys that correspond to features of a menu. When an “ALT” modifier key is latched in Microsoft® Word, for example, an output for the keys corresponding to selections available in the menu (e.g., “F” for “File,” “E” for “Edit,” and the like) may be activated to identify to a user what keystrokes will perform an identified function. The outputs for the limited entry set of keys may, for example, be highlighted (e.g., displaying a different appearance (e.g., a color), position (e.g., a raised height), feel (e.g., a tactile identifier such as a vibration or bump), and the like). Similarly, outputs corresponding to keyboard shortcuts (e.g., when data has been copied and is available to be inserted or pasted) or predicted keystrokes may also be activated.
• In other examples, a plurality of keys may be grouped together to provide a larger keyset for providing easier input (e.g., in a physical accommodation, a gaming environment, where a full keyset is not required, or the like). Further, outputs (e.g., displays) on the individual keys may display which particular keys are grouped together and what the group collectively represents. A group of keys may be collectively illuminated with a common color, or other representation, to identify the keys as being grouped together. Further, a display may further indicate an input for which the group of keys will collectively represent (e.g., a group of keys may collectively represent a single letter, number, function, command, or other input).
• In a keyboard, font and/or case changes may be directly represented on keys of a keyboard. Displays on the individual keys may show a true representation of how a particular key would be represented in a selected font. Where a Times New Roman font has been selected in an application, for example, keys of a keyboard may show how individual keys would be displayed in that font. Similarly, displays on the keys may show cases of letters depending on whether a “CAPS LOCK” key is activated or if a “SHIFT” key is latched. Also, displays on the keys may indicate functions that may be selected when a “FN” key is latched. Other indications are also possible.
• Where particular keys or combinations of keys are expected or required (e.g., a “CTRL,” “ALT,” “DEL” combination is required), those keys may be highlighted (e.g., through a display, position, feel, or other manner) and/or other keys may be dimmed or otherwise given a lower profile (e.g., retracted).
• “Timeout” or “lockout” sequences may also be indicated through displays on keys of a keyboard. Where repetitive striking of a key is disabled within a time period, for example, one or more displays on the keyboard may be used to indicate that the key is being locked. When a particular key is latched, for example, the key may be highlighted for a predetermined time period to indicate that the key is locked from receiving a further input during that time period. Displays on one or more keys may further be used to indicate that the time out is subsiding (e.g., an initial display indicating that the key is latched and a decay sequence to indicate the time out is subsiding).
• Invalid inputs on a keyboard may also be indicated to a user via one or more output on a keyboard. Outputs of a peripheral device may visually, spatially, tactually, or otherwise indicate that an invalid input has been received from that device.
• Graphic or other representations of particular available function may also be represented on an output of a peripheral device corresponding to a particular input of that peripheral device. A display on a key of a keyboard, for example, may depict a graphical representation (e.g., an icon) that corresponds to a particular function available by activation of a key of the keyboard.
• In a gaming or other environment, outputs of a peripheral device may be used to augment input options of the peripheral device. In one implementation, contextual clues based on a game or educational application may be provided. A “hint” mode in a maze game, for example, may activate displays showing valid navigational inputs (e.g., keys) that may be used to navigate the maze. Similarly, inputs of a peripheral device may be altered depending upon certain situations. In a role playing game, for example, a heightened sense of awareness may be accomplished by making inputs easier while a reduced sense of awareness (e.g., an intoxicated, drugged, or impaired character) may be accomplished by making user inputs of the peripheral device more difficult. Inputs of the peripheral device, for example, may indicate more or less information than would otherwise be provided. Further, layout of inputs may be altered to make input easier or more difficult depending on the conditions present in the game. Keys or other input devices may be raised or lowered in profile, highlighted or hidden, given more or less resistance, moved or assigned different values, or the like depending upon the conditions of the game. Combinations of input entry in a game may also be predicted and highlighted or diminished depending upon the circumstances.
• In an education application, e.g., a typing or musical instrument tutorial application, input devices may be augmented by output capabilities of the peripheral device. Predictive or desired inputs may be identified to aid a user in learning correct inputs or combinations of inputs.
• While particular examples may be given for one or more particular implementation of a peripheral device, such as for a keyboard, similar functionalities or capabilities may also be used with respect to other types of peripheral devices.
• An example of a hardware and operating environment ofFIG. 4 for implementing operations to associate an output of a peripheral device coupled to a computing system with an input of that peripheral device includes a general purpose computing device in the form of acomputer400, including aprocessing unit402, asystem memory404, and asystem bus418 that operatively couples various system components, including thesystem memory404 to theprocessing unit402. There may be only one or there may be more than oneprocessing unit402, such that the processor ofcomputer400 comprises a single central processing unit (CPU), or a plurality of processing units, commonly referred to as a parallel processing environment. Thecomputer400 may be a conventional computer, a distributed computer, or any other type of computer; the invention is not so limited.
• Thesystem bus418 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, a switched fabric, point-to-point connections, and a local bus using any of a variety of bus architectures. Thesystem memory404 may also be referred to as simply the memory, and includes read only memory (ROM)406 and random access memory (RAM)405. A basic input/output system (BIOS)408, containing the basic routines that help to transfer information between elements within thecomputer400, such as during start-up, is stored inROM406. Thecomputer400 further includes ahard disk drive430 for reading from and writing to a hard disk, not shown, amagnetic disk drive432 for reading from or writing to a removablemagnetic disk436, and anoptical disk drive434 for reading from or writing to a removableoptical disk438 such as a CD ROM or other optical media.
• Thehard disk drive430,magnetic disk drive432, andoptical disk drive434 are connected to thesystem bus418 by a harddisk drive interface420, a magneticdisk drive interface422, and an opticaldisk drive interface424, respectively. The drives and their associated computer-readable media provide nonvolatile storage of computer-readable instructions, data structures, program modules and other data for thecomputer400. It should be appreciated by those skilled in the art that any type of computer-readable media that can store data that is accessible by a computer, for example, magnetic cassettes, flash memory cards, digital video disks, RAMs, and ROMs, may be used in the exemplary operating environment.
• A number of program modules may be stored on thehard disk430,magnetic disk432,optical disk434,ROM406, orRAM405, including anoperating system410, one ormore application programs412,other program modules414, andprogram data416. In an exemplary implementation, a method for associating an output of a peripheral device with an input of the peripheral device, may be incorporated as part of theoperating system410,application programs412, orother program modules414.
• A user may enter commands and information into thepersonal computer400 through input devices such as akeyboard440 andpointing device442, for example, a mouse. Other input devices (not shown) may include, for example, a microphone, a joystick, a game pad, a tablet, a touch screen device, a satellite dish, a scanner, a facsimile machine, and a video camera. These and other input devices are often connected to theprocessing unit402 through aserial port interface426 that is coupled to thesystem bus418, but may be connected by other interfaces, such as a parallel port, game port, or a universal serial bus (USB).
• Amonitor444 or other type of display device is also connected to thesystem bus418 via an interface, such as avideo adapter446. In addition to themonitor444, computers typically include other peripheral output devices, such as aprinter458 and speakers (not shown). These and other output devices are often connected to theprocessing unit402 through theserial port interface426 that is coupled to thesystem bus418, but may be connected by other interfaces, such as a parallel port, game port, or a universal serial bus (USB). A media tuner module460 may also be connected to thesystem bus418 to tune audio and video programming (e.g., TV programming) for output through thevideo adapter446 or other presentation output modules.
• Thecomputer400 may operate in a networked environment using logical connections to one or more remote computers, such asremote computer454. These logical connections may be achieved by a communication device coupled to or integral with thecomputer400; the invention is not limited to a particular type of communications device. Theremote computer454 may be another computer, a server, a router, a network personal computer, a client, a peer device, or other common network node, and typically includes many or all of the elements described above relative to thecomputer400, although only amemory storage device456 has been illustrated inFIG. 4. The logical connections depicted inFIG. 4 include a local-area network (LAN)450 and a wide-area network (WAN)452. Such networking environments are commonplace in office networks, enterprise-wide computer networks, intranets and the Internet, which are all types of networks.
• When used in aLAN450 environment, thecomputer400 may be connected to thelocal network450 through a network interface or adapter428, e.g., Ethernet or other communications interfaces. When used in aWAN452 environment, thecomputer400 typically includes amodem448, a network adapter, or any other type of communications device for establishing communications over thewide area network452. Themodem448, which may be internal or external, is connected to thesystem bus418 via theserial port interface426. In a networked environment, program modules depicted relative to thepersonal computer400, or portions thereof, may be stored in a remote memory storage device. It is appreciated that the network connections shown are exemplary and other means of and communications devices for establishing a communications link between the computers may be used.
• In an example implementation, an input logical layer module and other modules may be embodied by instructions stored inmemory422 and/or storage devices429 or431 and processed by the processing unit421. Logical representations, device interface data sets, and other data may be stored inmemory422 and/or storage devices429 or431 as persistent datastores.
• The technology described herein may be implemented as logical operations and/or modules in one or more systems. The logical operations may be implemented as a sequence of processor-implemented steps executing in one or more computer systems and as interconnected machine or circuit modules within one or more computer systems. Likewise, the descriptions of various component modules may be provided in terms of operations executed or effected by the modules.
