Patent attributes
A cab having a human-machine interface to generate a holographic image in order to control comfort equipment installed in the cab. The human-machine interface includes: a camera capable of capturing images representing a gaze of an occupant, one image generation unit having (a) a computer capable of calculating the position of the location of the occupant's gaze from the captured images, the computer being adapted to generate the digital holographic image according to the position of the occupant's gaze, (b) a spatial light modulator receiving the generated digital holographic image, and (c) a light source illuminating the spatial light modulator. The human-machine interface also includes a reflector reflecting the light beams emitted by the spatial light modulator into a visualizing window to form a holographic image positioned between the windscreen and the seat.
