AI Technical Summary
Technical Problem
In existing technologies, the distance measurement from the waveguide sheet to the user's pupil is not accurate enough, which affects the display effect of AR or VR glasses.
Method used
By determining the angle between the user's pupil position and the electronic device position, and combining ultrasonic ranging technology, the distance between the waveguide plate and the pupil is calculated. A pupil tracking module, an angle calculation module, and a distance measurement module are used for precise measurement.
Benefits of technology
It improves the accuracy of distance measurement between the waveguide sheet and the pupil, thus enhancing the display effect of AR or VR glasses.
