Abstract
A control method for a head-mounted visual apparatus, a corresponding computing apparatus, a head-mounted visual apparatus and a computer-readable storage medium. The head-mounted visual apparatus has an infrared transceiver including an infrared light source array and an infrared detector. The control method comprises the steps of: driving each sub-light source to emit coherent infrared light to form an interference enhanced scanning light spot on a face of a user who wears the head-mounted visual apparatus; controlling each phase of the coherent infrared light emitted by each sub-light source respectively to make the scanning light spot move in the local area, including eyes, of the face of the user, to realize a scanning of the local area; and using the infrared detector to receive the infrared light reflected from the local area to generate scanning data.
