Problems solved by technology

In the prior art, head-mounted virtual reality or augmented reality equipment is mainly based on the dark pupil technology, and uses the corneal reflective point as a reference point to calculate the pupil-corneal reflective point vector to track the line of sight of the human eye. Corresponding to one eye tracking module, and the same light source is used in both eye tracking modules, resulting in the light emitted by the light sources in the two eye tracking modules will interfere with each other during calibration or use, increasing the error of the calculation result

Abstract

The invention discloses an eyeball-tracking device, comprising two eyeball-tracking modules used for tracking the sight of a user; each of the two eyeball-tracking modules is disposed to correspond with one eye; each of the two eyeball-tracking modules comprises a light source component and at least one image sensor component; the light source components face to the direction of eyes of the user and can form at least one corneal reflective spot on eye corneas of the user; the at least one image sensor component is used for continuously capturing images of the eyes of the user; and the image sensor component in each of the eyeball-tracking modules can only receive light emitted by the light source component in the corresponding eyeball-tracking module. The invention also discloses head-mounted virtual reality equipment and head-mounted augmented reality equipment by use of the eyeball-tracking device. According to the eyeball-tracking device, the head-mounted virtual reality equipment and the head-mounted augmented reality equipment by use of the eyeball-tracking device, the problem that the light source components interfere with each other when calibration or in use can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of eye tracking, in particular to an eye tracking device, a head-mounted virtual reality device and a head-mounted augmented reality device using the eye tracking device. Background technique [0002] Head-mounted virtual reality devices (also known as VR glasses, or VR helmets) and head-mounted augmented reality devices (also known as AR glasses, or AR helmets) are virtual reality and augmented reality products that are currently developing and popularizing rapidly. [0003] The mainstream technology of eye tracking is eye tracking and sight detection technology based on image processing, which calculates and records the position of the eyes in real time. In the prior art, head-mounted virtual reality or augmented reality equipment is mainly based on the dark pupil technology, and uses the corneal reflective point as a reference point to calculate the pupil-corneal reflective point vector to track the line ...
