Abstract

Multi-touch interfaces allow user interaction with multiple points of contact to control external devices such as game consoles, authenticate users, partition the interface for multiple users, and so forth. The multi-touch interface may provide graphical representations that are manipulated by users through multiple points of contact to participate in games running on an external game console. Additionally, user authentication may occur through multiple points of contact with the multi-touch interface where each user has a unique contact pattern that includes points of contact, location of points of contact, rhythm of points of contact, and so forth. The graphical representations may be customized based on the authentication of a user, and the multi-touch surface may be partitioned based on the number of users present.

Claims

1. A computer readable medium containing instructions for performing acts in conjunction with a multi-touch interface, the acts comprising:

receiving input signals in response to multiple points of simultaneous physical contact on the multi-touch interface;

comparing the input signals to data this is stored in a memory and that represents a pattern of physical contact associated with a user;

determining from the comparison whether the physical contact represented by the input signals matches the pattern of physical contact associated with the user; and

producing a signal value that indicates a successful authentication of the user and that identifies the user upon determining that the physical contact matches the pattern of the physical contact associated with the user.

2. The computer readable medium of claim 1, wherein the memory stores data representing a unique pattern of physical contact for a plurality of users and wherein the acts comprise producing signal values for each user that are authenticated by the pattern of physical contact.

3. The computer readable medium of claim 2, wherein the acts further comprise partitioning the multi-touch interface into a separate area for each user who is successfully authenticated.

4. The computer readable medium of claim 1, wherein the pattern of contact comprises a number and location of the points of contact.

5. The computer readable medium of claim 4, wherein the pattern of contact further comprises a rhythm from at least one of the points of contact, wherein the acts further comprise supplemental physiological sensing and considering information from the supplemental physiological sensing in addition to the pattern of physical contact.

6. The computer readable medium of claim 1, wherein the acts further comprise generating a display that is unique to the user identified by the signal.

7. The computer readable medium of claim 6, wherein generating the display comprises generating a display of a game controller, and wherein the acts further comprise generating control signals based on interaction with the game controller and outputting the control signals to a game console as control signals.

8. A device for generating external control signals, comprising:

a multi-touch interface that produces input signals in response to multiple points of simultaneous physical contact;

a processing device in data communication with the multi-touch interface, that analyzes the input signals to produce instructions to manipulate an aspect of an electronic game; and

an output interface for sending game control signals to a gaming console, the output interface receiving the instructions from the processing device and generating the game control signals based on the instructions.

9. The device of claim 8, further comprising memory storing data representing a pattern of physical contact in association with a user, wherein the processing device receives the input signals in response to the physical contact and compares at least a portion of the input signals to the stored data representing the pattern of physical contact to determine if the physical contact represented by the input signals matches the pattern of physical contact associated with the user, and that produces a signal value that indicates successful authentication of the user and that identifies the user upon determining that the physical contact represented by the pattern of physical contact matches the pattern of physical contact associated with the user.

10. The device of claim 9, wherein the processing device displays graphical controls on the multi-touch interface and wherein the processing device accesses information from memory specifying at least one characteristic of the displayed graphical controls that is associated with the user that has been successfully authenticated, and wherein physical contact by a user with the graphical controls causes the multi-touch interface to produce the input signals.

11. The device of claim 9, wherein the electronic game has a plurality of players, wherein the processing device defines an area of the multi-touch display that is dedicated for the identified user and wherein the processing device produces instructions in response to input signals stemming from physical contact within the defined area that specify manipulations of aspects of the electronic game associated with a particular player of the plurality.

12. The device of claim 8, wherein the processing device displays graphical controls on the multi-touch interface and wherein physical contact by a user with the graphical controls causes the multi-touch interface to produce the input signals.

13. A method of providing defined areas of interaction with a multi-touch display, comprising:

defining physical areas of the multi-touch display as logically separate areas without regard to content being displayed on the multi-touch display;

receiving multiple points of simultaneous physical contact on the multi-touch display;

determining which of the multiple points of simultaneous physical contact occur within each of the logically separate areas; and

producing at least one signal based on which of the multiple points of contact occur within each of the logically separate areas.

14. The method of claim 13, wherein a first signal corresponds to multiple points of physical contact within a first area of the multi-touch display and wherein a second signal different that the first signal corresponds to multiple points of physical contact within a second area of the multi-touch display.

15. The method of claim 14, wherein the first area of the multi-touch display corresponds to a control of a first external device and wherein the second area of the multi-touch display correspond to a control of a second external device.

16. The method of claim 13, further comprising receiving a first set of multiple points of physical contact on the multi-touch display and wherein defining the physical areas comprises basing a first of the physical areas on where the first set of multiple points of physical contact occurs on the multi-touch display.

17. The method of claim 16, further comprising:

detecting from the first set of multiple points of contact whether a pattern is present that matches a pattern stored in association with the identification of a first user; and

upon detecting that the pattern is present that matches the pattern stored in association with the first user, applying subsequent physical contact occurring within the first area as input to applications of the multi-touch interface that are associated with the first user.

18. The method of claim 16, wherein a first application of the multi-touch interface that is associated with the user is control information for an external game console.

19. The method of claim 18, further comprising displaying a game controller within the first area, and wherein the subsequent physical contact occurring within the first area is interaction with the game controller.

20. The method of claim 19, wherein displaying the game controller comprises displaying a game controller that is customized for the first user according to game controller customization data stored in association with the identification of the first user.
