Wearable display device and method for determining gaze positions

A method for determining gaze positions, applicable to a wearable display device, wherein the wearable display device comprises:

• a display panel, comprising a display region and a peripheral region surrounding the display region;
• a plurality of light-emitting elements, configured to emit light to be irradiated to eyes of a user;
• a plurality of photoelectric sensor assemblies, disposed in the peripheral region, wherein each of the photoelectric sensor assemblies is configured to receive optical signals, reflected via the eyes of the user, of the plurality of light-emitting elements, and convert the optical signals into electric signals, the electric signals being configured to determine a gaze position of the eyes of the user on the display panel;
• and
• an optical structure, disposed on a side, distal from the display panel, of the photoelectric sensor assembly, an orthographic projection of the optical structure on the display panel being within the peripheral region, and the optical structure comprises a light shielding region and a plurality of light transmitting regions, wherein the plurality of light transmitting regions are in one-to-one correspondence to the plurality of photoelectric sensor assemblies, each of the light transmitting regions at least being configured to transmit the optical signal to a corresponding photoelectric sensor assembly;
• and the method comprises:
• receiving optical signals, reflected via eyes of a user, of a plurality of light-emitting elements;
• converting the optical signals into electric signals;
• and
• determining a gaze position of the eyes of the user on a display panel based on signal values of the electric signals and a position of at least one of the photoelectric sensor assemblies.
