Abstract

The invention discloses an eyeball tracking method, device and a system applied to a terminal device. The method comprises the following steps: acquiring image information; Extracting eye feature information from image information, wherein the image information includes eye feature information, and forming an eye feature information set; Sending eye feature information set to the server; Receivingand parsing gaze feedback from the server. The invention solves the technical problem that the eyeball tracking algorithms of the prior art all run at the device end, which leads to large resource consumption of the device end.

Description

technical field [0001] The present invention relates to the technical field of eye tracking, in particular, to an eye tracking method, device and system applied to a terminal device. Background technique [0002] As an innovative way of interaction, eye tracking technology is more and more known to the public, and has been widely used in people's work and study. Among them, the processing flow of the eye tracking technology mainly includes the following three steps: [0003] Step S1, the eye tracking device acquires the facial image of the user using a collection device, where the collection device can be an optical device, an electrical device, etc.; [0004] Step S2, the eye tracking device processes the user's facial image, and extracts the user's eye feature information; [0005] In step S3, the eye tracking device processes the user's eye feature information to obtain the user's gaze direction and gaze point position. [0006] Currently, the above three steps are all...
