A touchless interaction with a computer is desirable as augmented reality devices become more of a reality. A user gesture may be recognizable using a built-in camera. A processor identifies a user pre-gesture based on digital images from the camera. The processor associates a point of interest on the display according to one of a shape and a position of the user pre-gesture. The processor identifies a change from the user pre-gesture to a user gesture based on the digital images from the camera, and the processor executes an appropriate action or program based on the user gesture.
