Abstract
A wearable display apparatus includes a control unit, a display unit, a light transmission unit, a semi-transparent photodetector unit and a signal processing unit. The display unit includes multiple light-emitting elements and is controlled by the control unit and outputs an optical image; the light transmission unit delivers the optical image to human eyes; the semi-transparent photodetector unit converts the light reflected from the human eyes to an electrical signal which includes information regarding the health status and gazing direction of the human eyes; the signal processing unit extracts information through analyzing the electrical signal and transmits the information to the control unit; the control unit adjusts an output image of the display unit in real time according to the information; and the light transmission unit and the semi-transparent photodetector unit propagate the external light beams to the human eyes.
