Problems solved by technology

Although this method is simple and easy to understand, it requires additional calibration steps. Once a new user is replaced or the user's characteristics change, it needs to be re-calibrated. Therefore, this calibration method is not a good user experience.

Embodiment Construction

[0052] The structural features and operation methods of this case are explained in conjunction with the diagrams, which will be described later for review and reference.

[0053] Please refer to " figure 1 ", which is a block diagram of the eye tracking system, as shown in the figure:

[0054] The present invention is a correction module 70 for eye tracking. The correction technology described above is applied to the eye tracking system 100. By displaying a sliding cursor graphic animation on the display screen 30, the user's movement can be tracked. The gaze direction of the eyes is calibrated with the correction samples in the database 25, and then the correction between the gaze direction of the eyes and the 30-pixel matrix of the display screen is completed.

[0055] The eye tracking system 100 is used to capture the user's eye image, and perform image analysis on the eye image, so as to convert the user's line of sight to the position relative to the display screen 30, t...

Abstract

The present invention discloses a correction module for eye tracking comprising an image generator, an image acquisition adjuster, and an operator. The image generator is used to display a cursor animation for the user's attention on a correction path, and the cursor on the cursor animation moves along the correction path. When the cursor is moved, the image acquisition adjuster captures the eye image of the user continuously through an image pickup device, thereby recording a plurality of eye gaze directions of the user. The operator forms a correction information coordinate sequence through the plurality of eye gaze directions of the user, and establishes a plurality of UI eye movement distribution ranges on the UI eye movement data table through a conversion function by the correction information coordinate sequence, and the UI eye movement distribution range on the UI eye movement data table is mapped to the corresponding position on the display screen. The present invention also discloses a correction method for eye tracking and a computer-readable recording medium.

Description

technical field [0001] The present invention relates to a calibration module for eye tracking, in particular to a calibration module that provides sliding image animations to correct a user's gaze direction. Background technique [0002] The way to control the computer has gradually changed with the improvement of computer performance. Traditionally, using the mouse, keyboard, and drawing pen to input signals to the computer system is convenient and fast, but in special cases, such as gradual freezing For people who are physically incomplete, disabled after injury, and who cannot simply and quickly operate the mouse, keyboard, drawing board, etc., this simple input method has been unable to meet their needs for computers or related electronic peripheral products. Use experience. [0003] Based on the above, the eye tracking technology has gradually been paid attention to, and gradually applied to related auxiliary applications. The main content of this technology is to use...
