Embodiment Construction

[0040] Such as figure 1 , the present invention relates to an interactive method of eye movement signal control. This method does not need any language and action, and directly realizes the control of the digital interface through the eye movement signal of the icon. Crowds, in some occasions where hand coordination is inconvenient, such as astronauts operating computers in spacecraft or space capsules, driving cars, surgical procedures, etc., can also use human-machine interfaces based on eye movement information to perform actions or communicate. First, pre-process the icon, including:

[0041] (1) Get the function icon

[0042] Obtain function icons in PNG format from the system files of any open source software, that is, the function identification symbols in the user interface. It is agreed that the total number of function icons of an open source software shall not exceed 108, and the control of eye movement signals for function icons with more than 108 functions metho...

Abstract

The invention discloses an interaction method for eye movement signal control. The method comprises the following steps of: (1) preprocessing obtained function icons; (2) digitally encoding eye movement signals; (3) storing an eye movement signal array of the function icons; (4) acquiring, outputting, calculating and recognizing the eye movement signals; and (5) confirming an eye movement instruction by a testee, wherein the step of preprocessing the icons comprises digitally encoding the function icons according to using frequency m of the function icons, each function icon corresponds to a unique digital number i, a digit w of the digital number i is an integer in an interval [1, 4], and when w is greater than or equal to 2, numbers adjacent to the digital numbers are not repeated. According to the method, eye movement signals, for different icon pictures, of users are directly acquired, and eye-machine interaction, for digital interfaces, of icons is realized according to differenteye movement signals, so that the interaction efficiency of the digital interfaces is improved.

Description

technical field [0001] The invention relates to an interaction method, in particular to an interaction method controlled by eye movement signals. Background technique [0002] With the rapid development of computer technology and artificial intelligence, interactive methods that conform to human's natural cognitive habits have become the mainstream of the development of human-computer interaction technology. In the way of channel interaction, the signal input device has also changed from mouse and keyboard to body movements, voice, eye movements and brain waves. According to Berger's research, the information obtained by the eyes accounts for about 80% of the five major sensory systems. Human beings can freely and flexibly control the movement of the eyeballs to look at different objects without special learning and training. Eye tracking technology is natural And intuitive advantages, become the common focus of many disciplines. [0003] Eye-computer interaction is a tech...
