USER INTERFACE ENABLED BY 3D REVERSALS

摘要

A method and system are provided where a user can imitate a tap gesture with a fingertip in space without a physical surface to tap on and, if the trajectory of the fingertip is tracked in the course of movement, the tap gesture is performed by a 3D reversal. In a 3D reversal, the trajectory becomes substantially reversed.

主权项

1. A computer implemented method for generating reversal events in a user interface, the method comprising:
creating a sampled trajectory of an object, wherein the object is at least a portion of a body of a user of the user interface, receiving a position event, the position event including position information of the object, updating the sampled trajectory with the position information in response to receiving the position event, performing reversal recognition on the updated sampled trajectory to identify a reversal, and upon identifying the reversal, generating a reversal event in the user interface.
