Abstract

The invention discloses a target positioning method and device based on visual line tracking technology, and relates to the electron information technical field; according to a precision changing rule of an ocular fixation point captured by the visual line tracking technology, offset compensation can be carried out for a visual line coordinate position in a mobile direction interaction interface edge area in a visual line mobile direction, thus improving measuring precision of an edge area ocular fixation point, more effectively positioning interaction targets in the edge area, and man-machine interaction is more natural and harmonious.

Description

technical field [0001] The present invention relates to the field of electronic information technology, in particular to a target positioning method and device based on gaze tracking technology. Background technique [0002] With the improvement of eye-tracking technology, eye-tracking interaction technology, as a new interaction mode, is increasingly adopted by various electronic products. [0003] At present, eye-tracking technology is mainly realized through the "pupil-corneal reflection method", which uses the theoretically invariable characteristics of Purchin's spots in the eye movement process to locate the pupil position on the eye image in real time, calculate the corneal reflection vector, and estimate the user's line of sight direction. However, in practical applications, when the line of sight moves to the edge of the screen, it will be accompanied by certain disturbances such as head movement, resulting in the highest measurement accuracy of the line of sight t...
