specific Embodiment approach

[0082] Optionally, in another embodiment of the present invention, a specific implementation manner of step S302 includes:

[0083] It is judged whether the line-of-sight information of the user tracked by the first type falls within the tracking range of the second type of device.

[0084] Wherein, if it is determined that the user's line of sight information tracked by the first type of device does not fall within the tracking range of the second type of device, it is determined that the user's line of sight information tracked by the second type of device cannot be obtained. Since the tracking range of the second type of device is relatively small, only when the user's line of sight information falls within the tracking range of the second type of device can the second type of device track the user's line of sight information and obtain the second type of line of sight information. The user's gaze information tracked by the device. Therefore, when it is judged that the use...

Abstract

The invention provides a sight line tracking method. The sight line tracking method comprises the steps: user sight line information tracked by first-type equipment is obtained, and whether user sightline information tracked by second-type equipment can be obtained or not is judged; the sight line tracking range and / or the sight line tracking precision of the first-type equipment and the second-type equipment are different; if it is judged that the user sight line information tracked by the second-type equipment cannot be obtained, the user sight line information tracked by the first-type equipment is output; and if it is judged that the user sight line information tracked by the second-type equipment can be obtained, the user sight line information tracked by the second-type equipment isobtained and output. Through mutual cooperation of the first-type equipment and the second-type equipment, the defects of the two types of equipment are compensated, thus large-range sight line tracking can be conducted, and the accurate user sight line information can be obtained at needed positions.

Description

technical field [0001] The present invention relates to the technical field of gaze tracking, in particular to a gaze tracking method, device and system. Background technique [0002] With the development of human-computer interaction technology, eye-tracking technology has received extensive attention. Gaze tracking technology is a method that uses eye movement measurement equipment to capture the user's eye image at the millisecond level, and estimates the relative position of the user's eyes by analyzing the relative positions of the pupil contour, iris contour, pupil center, iris center, and the reflection point of the external light source on the cornea. The technology of the line of sight direction or line of sight. [0003] Nowadays, people have begun to try to apply eye-tracking technology in cars to assist driving, for example, monitoring the driver's driving status, controlling the central control screen through eyesight, and so on. Since the driver's line of sig...
