Patent ID: 8432366

Claim:
A system comprising: one or more processors; one or more computer-readable storage media including instructions executable by the one or more processors; a touch input component to: obtain touch point information from at least one surface in a surface computing environment, and determine a vector of incidence based on the touch point information; one or more sensors that collect information related to a surrounding environment of the at least one surface that is used by a plurality of users; a touch discrimination component to: infer an association between a user of the plurality of users and a touch point based on at least one of the touch point information, accelerometer information obtained from a user device associated with the user, or environmental information, and distinguish input received from the user relative to other users of the plurality of users; a biometric sensor to identify a fingerprint based on the touch point information, to determine whether the fingerprint is associated with the user, and to associate the fingerprint with a new user when the fingerprint is unassociated with the user; an overhead sensor analysis component to use overhead optical sensors to acquire overhead environmental information, and ascertain movements of at least one user of the plurality of users based on the overhead environmental information; a facial analysis component to use one or more optical imaging sensors to determine a line of sight of at least one user of the plurality of users; and a threshold component to apply one or more thresholds to an image when the image is included in the touch point information; a fusion component to apply, based on a context of the surface, weightings to the touch point information and to the environmental information.
