USER POSITIONING WITHIN AN EYE-BOX OF A HEAD-UP DISPLAY

원문 (중국어)

A head-up display method includes determining a first intensity for a first target image based on a distance between a first viewing position and a reference viewing position; and illuminating a first hologram corresponding to the first target image to holographically reconstruct the first target image at the first intensity; then, determining a second intensity for a second target image based on a distance between a second viewing position different to the first viewing position and the reference viewing position; and illuminating a second hologram corresponding to the second target image to reconstruct the second target image at the second intensity; wherein the second intensity is different to the first intensity, and a difference between the first intensity and the second intensity indicates whether the second viewing position is closer to or further from the predetermined reference viewing position compared to the first viewing position.
