System and method for utilizing fingerprints as user inputs

## Abstract

An information handling system includes a tablet computer, which in turn includes a touch sensor, a sensor detector, and a processor. The sensor detector is configured to communicate with the touch sensor, and to detect a first fingerprint on the touch sensor. The processor is configured to communicate with the sensor detector, to determine that the first fingerprint is within a first zone of the touch sensor, to match the first fingerprint to a stored fingerprint for the first zone of the touch sensor, to determine a first input function associated with the first fingerprint based on the first fingerprint matching the stored fingerprint for the first zone, and to execute the first input function.

## Background
FIELD OF THE DISCLOSURE
This disclosure generally relates to information handling systems, and more particularly relates to utilizing fingerprints as user inputs to an information handling system.
BACKGROUND
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
An information handling system, such as a tablet computer, can include a virtual keyboard for receiving input functions to be performed by the tablet computer. For example, a user can utilize a virtual keyboard presented on a display screen of the tablet computer to compose an electronic mail message, compose a word processing document, perform actions during a video game application, or the like.

For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, entertainment, or other purposes. For example, an information handling system may be a personal computer, a PDA, a consumer electronic device, a network server or storage device, a switch router, wireless router, or other network communication device, or any other suitable device and may vary in size, shape, performance, functionality, and price, The information handling system may include memory, one or more processing resources such as a central processing unit (CPU) or hardware or software control logic. Additional components of the information handling system may include one or more storage devices, one or more communications ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.
FIGS. 1 and 2 show an information handling system in the form of a tablet computer 100. The tablet computer includes a front panel 102 and a display screen 104. The tablet computer 100 internally includes a processor 130, a sensor detector 132, a memory 134, and an input/output interface 136, In an embodiment, the memory 134 can be any type of non-volatile memory, such as flash memory, The input/output interface 136 can be any combination of a dock interface, a Bluetooth module, a wired or wireless Internet Protocol module, or the like. The processor 130 is in communication with the sensor detector 132, the memory 134, and the I/O interface 136. The sensor detector 132 is also in communication with the I/O interface 136.
As shown in FIG. 2, the tablet computer 100 also includes a back surface 202, a first group of touch sensors 210, 212, and 214, and a second group of touch sensors 220, 222, and 224. Each of the touch sensors 210-214 and 220-224 can be any type optical sensor capable of scanning a fingertip place on the touch sensor, and thereby receiving or detecting a fingerprint. The sensor detector 132 is in communication with each of the touch sensors 210-214 and 220-224. However, for simplicity the communication channels connecting the sensor detector 132 to the touch sensors 210-214 and 220-224 have not been shown. The sensor detector 132 can identify each of the touch sensors 210-214 and 220-224 as an individual zone of that touch sensor. For example, a fingerprint detected anywhere in touch sensor 210 can be identified by sensor detector 132 as being located in a zone of touch sensor 210.
The tablet computer 100 can be placed in a training mode to set user fingerprints to input functions for the tablet computer, Once the training mode is initiated, the user can place one of his or her fingers on one of the touch sensors, such as touch sensor 210, which in turn can scan the fingerprint and send the detected fingerprint to the sensor detector 132. Upon receiving the fingerprint, the sensor detector 132 can determine what touch sensor, such as touch sensor 210, the fingerprint was received from and then send the fingerprint along with a touch sensor identifier to the processor 130. The processor 130 can then determine whether the detected fingerprint is already associated with the determined touch sensor and stored in the memory 134. For example, the processor 130 can access memory 134 and determine whether the detected fingerprint is already associated with touch sensor 210.
If the fingerprint is already associated with touch sensor 210, the processor can determine the input function to be performed when the fingerprint is detected on that touch sensor. In an embodiment, the input function can be an alphanumeric key input of a keyboard, a space key input, any other input key from a keyboard, an action in a video game application running on the tablet computer 100, a sequence of actions, or the like. The processor 130 can then provide a message, on display screen 104, to the user indicating that the fingerprint is already associated with touch sensor 210, and to identify the current input function to be performed when the fingerprint is detected in the touch sensor 210. The processor 130 can also provide the user with a graphical user interface (GUI) on the display screen 104 to enable the user to change the input function to be performed when the fingerprint is detected in touch sensor 210. Upon the user either re-saving the current input function or saving anew input function for the fingerprint in touch sensor 210, the processor 130 can provide a message to the user indicating that a new fingerprint can be received, and the substantially same process can be performed or the user can exit the training mode.
However, if the fingerprint is not already associated with or mapped to touch sensor 210, the processor 130 can provide the GUI on the display screen 104 to enable the user to select an the input function to be performed when the fingerprint is detected in touch sensor 210. Upon the user selecting and saving an input function for the fingerprint in touch sensor 210, the processor 130 can provide a message to the user indicating that a new fingerprint can be received, and the substantially same process can be performed or the user can exit the training mode. In an embodiment, the user can repeat this process until the user has stored a desired number of fingerprints for any combination of the touch sensors 210-214 and 270-224.
In an embodiment, the training mode can be universal across every application executed in the tablet computer 100, such that the same fingerprint detected in the same touch sensor can be the same input function for all applications executed in the tablet computer. In another embodiment, the training mode can be different for each application or can include an option to select particular applications to assign the detection of a fingerprint in a touch sensor to a particular input function to be performed, such that one fingerprint in the same touch sensor can be different input functions depending on the application executing in the tablet computer 100. For example, the user can select that a particular fingerprint detected in touch sensor 220 is the alphanumeric character ‘a’ while the tablet computer 100 is executing a word processing application, a text messaging application, an electronic mail application, or the like. However, the same fingerprint detected in the touch sensor 220 is a jump input function while the tablet computer 100 is executing a video game application.
During normal operation, a user can hold the tablet computer 100 in such a way that the user's fingers wrap around the tablet computer and rest near the touch sensors 210-214 and 220-224 on the back surface 202. The user can also hold the front surface 102 of the tablet computer 100 with his or her thumbs to securely hold the tablet computer. The user can then use his or her fingerprints on the touch sensors 210-214 and 220-224 to perform different actions in an application running on the tablet computer 100. For example, the tablet computer 100 may be executing an electronic mail application and the user can utilize each of his or her fingerprints in the different touch sensors 210-214 and 220-224 to input different alphanumeric character while composing an electronic mail message.
A touch sensor, such as touch sensor 212, can detect a fingerprint and can provide the fingerprint to the sensor detector 132, which in turn can determine that the fingerprint was detected at touch sensor 212. The sensor detector 132 can then provide the fingerprint and touch sensor identification, such as an identification of touch sensor 212, to the processor 130, and the processor can determine an input function to perform based on the fingerprint and the touch sensor identification. The processor 132 can access memory 13.4 to determine the input function to perform by correlating the fingerprint with the touch sensor 212, For example, the processor 130 can determine that the detected fingerprint in touch sensor 212 is associated with the alphanumeric character ‘t’, and the processor can then perform the input function by outputting the letter ‘t’ in the electronic mail application. The processor 130, sensor detector 132, memory 134, and touch sensors 210-214 and 220-224 can continue to communicate while the user is pressing his or her fingertips to the touch sensors to determine different input functions to execute as described above until the user exits the application, such as an email application, executing in the tablet computer 100.
FIG. 3 shows a rear view of another embodiment of the tablet computer 100. As shown in FIG. 3, the rear surface 202 includes touch sensors 302 and 304, and each of the touch sensors include one or more zones. For example, touch sensor 302 includes zones 310, 312, and 314, and touch sensor 304 includes zones 320, 322, and 324. The sensor detector 132, shown in FIG. 1, is in communication with each of the touch sensors 302 and 304. However, for simplicity the communication channels connecting the sensor detector 132 to the touch sensors 302 and 304 have not been shown.
The touch sensors 302 and 304 can be different touch sensors that each has continuous zones without any gaps in the touch sensor, In an embodiment, the size of each of the zones of a touch sensor can dynamically vary between uses of the tablet computer 100. For example, zone 312 can always be in between zones 310 and 314 of touch sensor 302, but the size of each of the zones can vary based different factors, such as the size of the user's hands, how the user holds his or her hands on the tablet computer 100, or the like.
In an embodiment, the user can provide a multiple touch event 350 as an input on one of the touch sensors, such as touch sensor 302. For example, as shown in FIG. 3, the multiple touch event 350 can be two or more fingerprints detected at substantially the same time on the touch sensor 302. The sensor detector 132 can receive the multiple touch event 350 from the touch sensor 302 and determine the location of the multiple touch event on the touch sensor. The sensor detector 132 can then assign or set different zones in the touch sensor 302 based on the location of the multiple touch event 350. In an embodiment, the sensor detector 132 can set zone 312 to have a vertical orientation within touch sensor 302 and to include the location of the multiple touch event 350. The sensor detector 132 can then assign or set zone 310 to include a region of the touch sensor 302 in between zone 312 and an edge of the touch sensor toward an edge of the back surface 202, and can assign or set zone 314 to include the remaining region of the touch sensor 302, such as in between zone 312 and an edge of the touch sensor toward the middle of the back surface. The sensor detector 132 can also receive a multiple touch event 350 on the touch sensor 304 and assign or set the zones for touch sensor 304 in substantially the same manner, such that zone 322 is centered around the location of the multiple touch event, and zones 320 and 324 are located on opposite sides of zone 322 within touch sensor 304.
The tablet computer 100 can then be placed in a training mode or normal operation mode. In training mode, the user can place one of his or her fingers on one of the touch sensors, such as touch sensor 304, which in turn can scan the fingerprint and send the detected fingerprint to the sensor detector 132. Upon receiving the fingerprint, the sensor detector 132 can determine what zone of a touch sensor, such as zone 320 of touch sensor 304, the fingerprint was received from and then send the fingerprint along with a touch sensor zone identifier to the processor 130. The processor 130 can then determine whether the detected fingerprint is already associated with the determined touch sensor zone and stored in the memory 134. For example, the processor 130 can access memory 134 and determine whether the detected fingerprint is already associated with zone 320 of touch sensor 304.
If the fingerprint is already associated with touch sensor 210, the processor can determine the input function to be performed when the fingerprint is detected on that touch sensor. The processor 130 can then provide a message, on display screen 104, to the user indicating that the fingerprint is already associated with zone 320 of touch sensor 304, and to identify the current input function to be performed when the fingerprint is detected in zone 320 of touch sensor 304. The processor 130 can also provide the user with the GUI on the display screen 104 to enable the user to change the input function to be performed when the fingerprint is detected in zone 320 of touch sensor 304. Upon the user either re-saving the current input function or saving anew input function for the fingerprint in zone 320 of touch sensor 304, the processor 130 can provide a message to the user indicating that a new fingerprint can be received, and the substantially same process can be performed or the user can exit the training mode.
However, if the fingerprint is not already associated with or mapped to zone 320 of touch sensor 304, the processor 130 can provide the GUI on the display screen 104 to enable the user to select an the input function to be performed when the fingerprint is detected in zone 320 of touch sensor 304. Upon the user selecting and saving an input function for the fingerprint in zone 320 of touch sensor 304, the processor 130 can provide a message to the user indicating that a new fingerprint can be received, and the substantially same process can be performed or the user can exit the training mode. In an embodiment, the user can repeat this process until the user has stored a desired number of fingerprints for any combination of the zones 310-314 of touch sensor 302 and zones 320-324 of touch sensor 304.
During normal operation, a user can hold the tablet computer 100 in such a way that the user's fingers wrap around the tablet computer and rest near the touch sensors 302 and 304 on the back surface 202. The user can also hold the front surface 102 of the tablet computer 100 with his or her thumbs to securely hold the tablet computer. The user can then perform a multiple touch event 350 on both touch sensors 302 and 304 to cause the sensor detector 132 to assign or set the zones within the touch sensors. The assigned zones can continue to be mapped to the input functions selected during the training mode no matter where the current boundaries for the zones are assigned. For example, if the multiple touch event 350 results in the sensor detector 132 shifting zone 312 left or right on the touch sensor 302, the processor 130 will continue to map the same input functions to the zone, because the sensor detector can provide the zone and touch sensor identification to the processor.
A touch sensor, such as touch sensor 302, can detect a fingerprint and can provide the fingerprint to the sensor detector 132, which in turn can determine that the fingerprint was detected at zone 314 of touch sensor 302. The sensor detector 132 can then provide the fingerprint along with the touch sensor identification, such as an identification of zone 314 of touch sensor 302, to the processor 130, and the processor can determine an input function to perform based on the fingerprint and the touch sensor identification. The processor 132 can access memory 134 to determine the input function to perform by correlating the fingerprint with zone 314 of touch sensor 302. For example, the processor 130 can determine that the detected fingerprint in zone 314 of touch sensor 302 is associated with a jump action in a video game application executing in tablet computer 100, and the processor can then perform the input function.
FIGS. 4 and 5 show respective front and rear views of the tablet computer 100 and a dock 400. As shown in FIG. 4, the dock 400 includes a cradle 402, and handles 402 and 404. The cradle 401 includes a bottom rail 405 and a top rail 502 (shown in FIG. 5). The handle 402 includes a loop 406 and control inputs 408. The handle 404 includes a loop 406, a control input 408, and touch sensors 410 and 412. The tablet computer includes a front panel 102 and a display screen 104. The tablet computer 100 internally includes a processor 130, a sensor detector 132, a memory 134, and an input/output interface 136. The dock 400 internally includes an I/O interface 440 to communicate with the I/O interface 136 of the tablet computer 100. The input/output interfaces 136 and 440 can be any combination of a dock interface, a Bluetooth module, a wired or wireless Internet Protocol module, or the like. As shown in FIG. 5, the handle 402 includes touch sensors 510, 512, and 514, the handle 504 includes touch sensors 520, 522, and 524, and the tablet computer 100 includes aback surface 202 in physical communication with top rail 502 of the cradle 401. The I/O interface 440, shown in FIG. 4, is in communication with each of the control inputs 408, and with each of the touch sensors 410, 412, 510-514, and 520-524. However, for simplicity the communication channels connecting the I/O interface 440 with each of the control inputs 408, and with each of the touch sensors 410, 412, 510-514, and 520-524 have not been shown.
The tablet computer 100 and dock 400 can be placed in a training mode to set user fingerprints on the touch sensors 410, 412, 510-514, and 520-524 of the dock to input functions for the tablet computer. Once the training mode is initiated, the user can place one of his or her fingers or thumbs on one of the touch sensors, such as touch sensor 410, which in turn can scan the fingerprint and send the detected fingerprint to the sensor detector 132 via the I/O interfaces 440 and 136. As used herein, a fingerprint can be both the unique print on the tip of one of the fingers on either hand or can the print on the tip of one of the thumbs on either of the individual's hands. Upon receiving the fingerprint, the sensor detector 132 can determine what touch sensor, such as touch sensor 410, the fingerprint was received from and then send the fingerprint along with a touch sensor identifier to the processor 130. The processor 130 can then determine whether the detected fingerprint is already associated with the determined touch sensor and stored in the memory 134. For example, the processor 130 can access memory 134 and determine whether the detected fingerprint is already associated with touch sensor 410.
If the fingerprint is already associated with touch sensor 410, the processor can determine the input function to be performed when the fingerprint is detected on that touch sensor. The processor 130 can then provide a message, on display screen 104, to the user indicating that the fingerprint is already associated with touch sensor 410, and to identify the current input function to be performed when the fingerprint is detected in the touch sensor 410. The processor 130 can also provide the user with the GUI on the display screen 104 to enable the user to change the input function to be performed when the fingerprint is detected in touch sensor 410. Upon the user either re-saving the current input function or saving a new input function for the fingerprint in touch sensor 410, the processor 130 can provide a message to the user indicating that a new fingerprint can be received, and the substantially same process can be performed or the user can exit the training mode.
However, if the fingerprint is not already associated with or mapped to touch sensor 410, the processor 130 can provide the GUI on the display screen 104 to enable the user to select an the input function to be performed when the fingerprint is detected in touch sensor 410. Upon the user selecting and saving an input function for the fingerprint in touch sensor 410, the processor 130 can provide a message to the user indicating that a new fingerprint can be received. In an embodiment, the user can repeat this process until the user has stored a desired number of fingerprints for any combination of the touch sensors 410, 412, 510-514, and 520-524.
In an embodiment, the training mode for the touch sensors 410, 412, 510-514, and 520-524 of dock 400 can be universal across every application executed in the tablet computer 100, such that the same fingerprint detected in the same touch sensor can be the same input function for all applications executed in the tablet computer. In another embodiment, the training mode can be different for each application or can include an option to select particular applications to assign the detection of a fingerprint in a touch sensor to a particular input function to be performed, such that one fingerprint in the same touch sensor can be different input functions depending on the application executing in the tablet computer 100.
During normal operation, a user can hold the handles 402 and 404 of dock 400 in such a way that the user's fingers wrap around the tablet computer and rest near the touch sensors 510-514 and 520-524 on the back surface 202, and one of his or her thumbs to be near touch sensors 410 and 412. For example, the user can rest the loops 406 of the handles 402 and 404 on the user's hands to allow him or her to move his or her fingers without risk of dropping the dock 400 and tablet computer 100. The user can then use his or her fingerprints on the touch sensors 410, 412, 510-514, and 520-524 to perform different actions in an application running on the tablet computer 100. For example, touch sensor 524 can receive a fingerprint and can provide the fingerprint to sensor detector 132 via the I/O interfaces 440 and 135. The sensor detector 132 and processor 130 can then operate as described above to perform an input function associated with the detected fingerprint in touch sensor 524.
As shown in FIG. 5, touch sensor 510-514 and 520-524 are separate touch sensors. However, in an embodiment, touch sensors 510-514 can be individual zones of a single touch sensor, and touch sensors 520-524 can be individual zones of another touch sensor substantially similar to the touch sensors described above with respect to FIG. 3. In this embodiment, the sensor detector 132 can utilize a multiple touch event to assigned or set the different zones of the touch sensors on the handles 402 and 404 as described above.
FIG. 6 shows a flow diagram of a method 600 for executing a training mode to associate fingerprints to an input function. The flow begins at block 602, during which an information handling system, such as a tablet computer, enters a training mode. In an embodiment, the training mode can be selected via a soft button on the tablet computer, by voice prompt, or the like. Additionally, the training mode can be entered into while the tablet computer is both connected to and not connected to a dock. At block 604, a fingerprint is detected at a touch sensor. In an embodiment, the touch sensor can be located on a rear panel of the tablet computer, on a rear panel of the dock connected to the tablet computer, on a front panel of the dock, or the like. The flow continues at block 606, and a particular zone of the touch sensor, which the fingerprint is detected, is determined. For example, the touch sensor can have three separate zones, and the fingerprint can be located in the third zone.
At block 608, a determination is made whether the fingerprint matches a stored fingerprint for the particular zone. In an embodiment, fingerprints that were previously received/detected during a training mode can be associated with the different zones of the touch sensor and can be stored in a memory of the tablet computer. In an embodiment, the same fingerprint can be associated with a different input function depending on which zone of the touch sensor the fingerprint is detected. In an embodiment, a processor can compare the detected fingerprint to each of the fingerprints, if any, that are stored in the memory and that are associated with the particular zone in which the fingerprint was detected. If the fingerprint matches a stored fingerprint for the particular zone, the flow continues as described above at block 604. However, if the fingerprint does not match a stored fingerprint for the particular zone, a prompt is provided to the user of the tablet computer requesting that the user select an input function for the fingerprint when detected in the particular zone. In an embodiment the input function can be an alphanumerical character of a keyboard, an action in a video game application, a sequence of actions in the videogame application, or the like. At block 610, the fingerprint is stored, in a memory, as being associated with the selected input function when the fingerprint is detected in the particular zone of the touch sensor.
FIG. 7 shows a flow diagram of a method 700 for performing an input function in response to a detected fingerprint. In an embodiment, the method 700 can be used in conjunction with the method 600 described above, For example, method 600 can be executed prior to method 700 been executed, at any point white method 700 is being executed, or the like.
At block 702, a multiple touch event is detected. In an embodiment, the multiple touch event can be registered on a touch sensor and detected by a sensor detector of the of a tablet computer. The multiple touch event can detected when more than one fingerprint is received at the touch sensor. In an embodiment, the touch sensor can be located on the rear panel of a tablet computer, a rear panel of a dock connected to the tablet computer, a front panel of the dock, or the like. At block 704, the touch sensor can be divided into multiple zones the based on the location of the multiple touch event. In an embodiment, the touch sensor can be divided into three separate zones, and the center zone can be located in a vertical orientation along the touch sensor where the multiple touch event was detected. An additional zone can be identified/defined on each side of the center zone. In this embodiment, the multiple touch event and location thereof can set a resting place for the user's hands on the touch sensor so that the touch sensor can be optimized for the user and the center zone of the touch sensor is located at the resting location of the user's hands. Thus, depending on the size of the user's hands, the center zone of the touch sensor can be adjusted closer to or further away from an edge of the tablet computer.
At block 706, a fingerprint is detected on the touch sensor. The flow then proceeds to block 708, and a zone that the fingerprint is detected in is determined. An input function for the fingerprint is determined based on the zone of the touch sensor at block 710. In an embodiment, the same fingerprint can be associated with a different input function depending on which zone of the touch sensor the fingerprint is detected. In an embodiment, a processor can compare the detected fingerprint to each of the fingerprints, if any, that are stored in a memory and that are associated with the zone in which the fingerprint was detected. At block 712, the determined input function is performed.
