摘要:
A touch sensor provides frames of touch sensor data, as the touch sensor is sampled over time. Spatial and temporal features of the touch sensor data from a plurality of frames, and contacts and attributes of the contacts in previous frames, are processed to identify contacts and attributes of the contacts in a current frame. Attributes of the contacts can include, whether the contact is reliable, shrinking, moving, or related to a fingertip touch. The characteristics of contacts can include information about the shape and rate of change of the contact, including but not limited to a sum of its pixels, its shape, size and orientation, motion, average intensities and aspect ratio.

Techniques for assigning a gesture dictionary in a gesture-based system to a user comprise capturing data representative of a user in a physical space. In a gesture-based system, gestures may control aspects of a computing environment or application, where the gestures may be derived from a user's position or movement in a physical space. In an example embodiment, the system may monitor a user's gestures and select a particular gesture dictionary in response to the manner in which the user performs the gestures. The gesture dictionary may be assigned in real time with respect to the capture of the data representative of a user's gesture. The system may generate calibration tests for assigning a gesture dictionary. The system may track the user during a set of short gesture calibration tests and assign the gesture dictionary based on a compilation of the data captured that represents the user's gestures.
