Embodiment Construction

[0019] A correction method for an eye mouse such as figure 1 , including the following steps:

[0020] Step 1. Obtain the corresponding eye image when the user looks directly at the correction points on the display screen; there are at least four correction points;

[0021] When the user looks directly at the different calibration points on the display screen, the user's eyeballs will be in different corresponding positions. When acquiring images of the eyeballs at these positions, in this embodiment, there are 9 calibration points, located at Display the four corners of the screen, the midpoints of the four sides and the center of the display screen;

[0022] In general, the more calibration points, the more accurate the calibration, but in fact, with the increase of calibration points, the user's calibration procedures will become more and more cumbersome, reducing the calibration efficiency, and in the process of acquisition, the user's operation must be standardized , su...

Abstract

The invention provides a method and a device for correcting an eye mouse. The device comprises a photosensitive component and an image processing system. The method comprises the following steps of: 1, acquiring a corresponding eye image when a user directly looks at a correcting point on a display screen; 2, analyzing the eye image to acquire corresponding eyeball characteristic information; and 3, judging whether the corresponding eyeball characteristic information is correct or not according to correcting point positional information and the eyeball characteristic information, and returning to execute the step 1 if the corresponding eyeball characteristic information is incorrect. Before the eye mouse is actually applied, the eye mouse is corrected, errors or faults due to the fact that the user does not look at the correct position or the user looks at other places when the eye image is shot can be avoided, and the positioning accuracy of the eye mouse can be improved.

Description

technical field [0001] The invention relates to the technical field of mice, in particular to an eye mouse calibration method and a device thereof. Background technique [0002] With the development of information technology, computers have become more and more popular. The mouse, as an essential part of the computer, has also entered thousands of households along with the computer. However, the use of the traditional mouse also brings many problems. First of all, the traditional mouse is based on It is designed for hand movement, which obviously makes it impossible for those who cannot move their hands to effectively operate the mouse, and thus cannot effectively operate the computer. In addition, the medical field has also confirmed that using a traditional mouse for a long time will cause physical damage to human wrist muscles, ranging from temporary soreness to severe long-term muscle diseases that cannot be cured. [0003] Like this, a kind of eye mouse based on visual...
