Abstract

The invention discloses an eye tracking data processing method and system. The method includes: a terminal device sends an eye tracking calibration parameter to a server, and the eye tracking calibration parameter includes at least a first parameter value of a first parameter type, and a device with the terminal device The first degree of confidence corresponding to the model; the server judges whether the saved value of the first parameter type and the second degree of confidence corresponding to the saved value are stored; if the server stores the saved value of the first parameter type and the second degree of confidence corresponding to the saved value confidence level, the server judges whether the second confidence level is less than the first confidence level; if the second confidence level is less than the first confidence level, the server replaces the saved value and the second confidence level with the first parameter value and the first confidence level respectively . The invention can solve the problem that low-precision terminal equipment cannot obtain high-precision calibration parameter values ​​in the prior art.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an eye tracking data processing method and system. Background technique [0002] Eye tracking technology is a technology with broad application prospects. It has received widespread attention as a means of human-computer interaction and improving user experience. It is not only used in mobile Internet terminal devices, but also in the field of VR (Virtual Reality, virtual reality). Key technologies deemed unavailable in the future. [0003] Eye tracking technology collects user's eye data to achieve eye movement tracking, and generally requires initialization, such as calibration operations before each use, to obtain calibration parameter values ​​(such as KAPPA angle, corneal refractive index, etc.). These initialization tasks are generally completed on the user's terminal equipment, such as mobile phones, VR all-in-one machines, computers, etc., which depend on the c...
