Abstract

The invention discloses an eye control auxiliary input method based on a depth camera. According to the method, the sight line direction and the coordinates of the sight line and the screen fixation point can be determined according to eyeballs and eye features of a person; according to the method and the device, the required words can be selected in the eye gaze selection process, and the input can be realized by directly clicking the space key, so that the movement selection of a mouse or the clicking of number keys is omitted. The use convenience degree of the user is improved, and the friendly degree of human-computer interaction is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent input, and more specifically relates to an eye control auxiliary input method based on a depth camera. Background technique [0002] At present, typing input is a very important and frequently used input method in the process of using an electronic device. Among the input methods used in daily life, the most commonly used input method is to use pinyin for input. During the input process, the input method will give priority to the user according to the meaning of the phrase, the frequency of use of the fixed phrase and the user's habit. The user has the greatest possibility of choice. , the words with higher frequency of use and greater possibility of selection will appear in the front position. If the word that appears in the first position of the input panel is the word that the user needs, just click A blank space can be selected for entry. [0003] However, due to the frequency of...
