TOUCHLESS IMAGE-BASED INPUT INTERFACE

A method for input detection at a computing device includes receiving, from a camera, a plurality of images depicting a user hand. The plurality of images are processed to detect a plurality of user intent parameters, including a predefined activation gesture performed by the user hand. Responsive to the plurality of user intent parameters satisfying a gesture input activation condition, the plurality of images are processed to detect a movement of the user hand consistent with a predefined input gesture. The predefined input gesture is mapped to a computer control action, and the computer control action is performed in response to the predefined input gesture.
