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.
