Abstract:
1. A man-machine interface method executed by an interactive device comprising a display, a camera, and an image analyzing means, the method comprising: (a) capturing an image with the camera; (b) analyzing the image to detect at least one human face; (c) determining a measurement parameter associated with the human corresponding to the human face; (d) displaying on the display a visual representation of the human face where the human face was detected; (e) defining a plurality of interactive zones, each interactive zone being associated with a command to the device, each interactive zone being placed at a distance from the human face based on the measurement parameter and representing a distance accessible by the arm of the human corresponding to the human face; (f) detecting an activation movement in one of the plurality of interactive zones; (g) executing the command associated with the interactive zone in which the activation movement was detected by the device; and (h) iteratively repeating steps (a) though (d) in order to maintain a constant ratio between the human face and the interactive zones in order to allow a constant user behavior while entering commands to the interactive device as a user moves relative to the camera.
