Abstract

The present invention provides a final reading position display method and system based on eye tracking. The method comprises the following steps: detecting that lines of sight leave a reading window; calculating a final reading position; displaying the final reading position; detecting that the lines of sight return to the reading window; and canceling display of the final reading position. The present invention further provides a system for implementing the method provided by the present invention. The system comprises the following modules: an eye-tracking data receiving module, used for establishing a connection with an external eye-tracking system and acquiring eye-tracking data; a ''lines of sight leave the reading window'' detecting module, used for detecting whether lines of sight of a user leave a current reading window; a final reading position calculating module, used for calculating a final reading position of the user in the current reading window; a final reading position display module, used for displaying the final reading position in the reading window; a ''lines of sight return to the reading window'' detecting module, used for detecting whether the lines of sight of the user return to the original reading window; and a final reading position display canceling module, used for canceling a display effect of the final reading position in the current reading window.

Description

technical field

[0001] The invention relates to the fields of human-computer interaction, visual cognition, etc., and in particular to a method and system for displaying the last reading position based on eye movement tracking. Background technique

[0002] In the process of reading on electronic devices such as computers, people often pause reading, for example, they need to temporarily interrupt reading to deal with other tasks, or switch to other program windows for operation. And when the user starts reading again, it often takes a while to find the last reading position. The process of recalling and searching for the last reading position significantly reduces the user's reading efficiency and experience level, especially when the user often needs to pause and resume reading.

[0003] Eye tracking technology can calculate the position of the user's gaze on the screen in real time, and then calculate the last reading position. However, there is currently a lack of prec...
