Research and Application of Eye Movement Interaction based on Eye Movement Recognition

Abstract

Generally, human-computer interaction is an interaction and operation between users and machine hardware. The user submits instructions to the machine, and the machine outputs the processed data and results to the user after receiving the instructions from the user. Mouse, keyboard, etc. are common input channels. With the maturity of eye tracking technology and the development of equipment miniaturization, turning eye movements into human-computer interaction input channels has become a hot spot in the field of human-computer interaction. Therefore, this paper analysed the physiological characteristics of eye movement, proposed the design principles and framework of eye movement interaction, and designed three kinds of eye movement recognition algorithms of fixation, saccade and blink. On this basis, using Unity 3D cross-platform development engine as a development tool, a children’s attention training game application based on eye movement interaction is designed. The game is designed to combine eye movement interaction technology with attention training mode, simplify the control mode of the game, get attention feedback at the first time, achieve better training effect and improve the efficiency of human-computer interaction.
