Abstract

The invention relates to a virtual reality interaction method and device based on eye movement tracking, being characterized in that eyeball movement is tracked in real time by measuring the positionsof visual attention focuses of eyes; and an infrared light source and an infrared camera are adopted for collecting eye movement information, and the positions of pupils are measured by tracking andcalculating the center positions of the pupils in an eye image, and the movement track of the pupils is established. Furthermore, the virtual reality interaction device based on eye movement trackingcan monitor the physiological or cognitive state and emotional changes, such as frightening and stimulation, of a user in real time by monitoring the changes of pupils, and can monitor eye movement tracks and the changes, such as the corresponding degree of dilation or reduction, of the pupils and feed the changes back to the main control module.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, and more specifically, to an eye-tracking-based virtual reality interaction method and device. Background technique [0002] Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. It is a system simulation of multi-source information fusion, interactive three-dimensional dynamic vision and entity behavior. Provide users with an immersive interactive environment in the virtual three-dimensional space. [0003] In the field of virtual reality, due to the advantages of price and convenience, head-mounted virtual reality devices are mainly oriented to ordinary consumers in the market. Users can use the display of the head-mounted virtual reality device Watch the virtual scene on the screen. The current virtual reality devices in the prior art, such as head-mounted virtual real...
