Optimization Design Of Temporal And Spatial Dimension Of Eye Control System Based On Blink

Eye control interaction,as one of the natural interaction characteristics,is gradually expanding the audience and serving more and more people.This paper organizes and summarizes the domestic and foreign various eye point the advantages and disadvantages and limitations of the human-computer interaction system,based on the blink of an eye control system of the existing research,the blink of an eye blink of the eye control system trigger actions to carry on the study of time dimension and space dimension,further puts forward the composite interaction based on gaze with the blink of an eye movements in the eyes of the control system controls the locking time optimal parameters,And the scope and direction of blink eye drift in spatial dimension.In this paper,the locking time triggered by blinking is studied.The optimal locking time of the control in the eye control system is 650ms by ergonomics experiments.At the same time,subjective evaluation experiment was conducted on the subjects,and the results of subjective evaluation were consistent with the results of ergonomics experiment.Secondly,the spatial characteristics of blink triggering are studied.The eye drift direction and distance of blinking action are studied by adding a variety of locking range to the control.According to the analysis of the experimental results,it is found that the main drift direction of the blinking movement is the upper right corner in the blinking eye control system.At the same time,according to the results of ergonomics experiment and subjective evaluation,the system can produce a certain drift distance when blinking,and the system has the highest success rate when the Angle of view corresponding to the locking range is 21.074°.Finally,this paper proposes a design scheme of blink control system based on flexible sensor.The system includes the blink detection system and the control system.The blink detection system mainly realizes the collection of blink signals and the recognition of once or twice blink commands,while the control system controls the switch of LED lamp belt and the color change by signal output.This system mainly realizes the following functions:blink signal acquisition function,blink detection function,LED lighting function.This paper provides theoretical support for the application of blinking in eye control system by studying the relevant time and space parameters of blinking trigger action.And improves the experience of using blinking trigger in eye control system.Based on the multiaction interaction combination,the system flow design of blinking trigger interaction is further refined.
