Multi-touch interfaces for user authentication, partitioning, and external device control
First Claim
1. A device for user authentication, comprising:
- a multi-touch interface producing input signals in response to multiple points of simultaneous physical contact;
a processor in data communication with the multi-touch interface; and
a memory, in data communication with the processor, configured to store data that represents a pattern of physical contact associated with a user and storing instructions which, when executed by the processor, cause the processor to perform operations comprising;
comparing the input signals to the data that is stored in the memory that represents the pattern of physical contact associated with the user,determining from the comparison whether physical contact represented by the input signals matches the pattern of physical contact associated with the user, andproducing a signal value that indicates a successful authentication of the user and that identifies the user upon determining that the physical contact represented by the input signals matches the pattern of the physical contact associated with the user.

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.

8. A tangible computer readable medium containing instructions which, when executed by a computer, cause the computer to perform acts in conjunction with a multi-touch display, the acts 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 a signal based on which of the multiple points of contact occur within each of the logically separate areas. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for user authentication, comprising:
-
receiving, via a multi-touch interface, input signals in response to multiple points of simultaneous physical contact on the multi-touch interface; comparing the input signals to data that is stored in a memory and that represents a pattern of physical contact associated with a user; determining from the comparison whether 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 represented by the input signals matches the pattern of physical contact associated with the user. - View Dependent Claims (15, 16, 17, 18, 19, 20)
