Design Of Smooth Pursuit In Eye Control System And Visual Representation Of Interface Elements Research

With the advent of the Internet era,human-computer interaction is no longer limited to the traditional WIMP interaction mode.The application of a variety of new interactive methods has gradually entered people's daily lives.Eye-controlled interaction,as one of the interaction methods that has natural interaction characteristics and fits people's daily life and operating habits,is gradually expanding the audience and serving more and more people.The field of eye control interaction is very pioneering and has broad prospects for development.This topic analyzes the characteristics,advantages,and disadvantages of the eye control system at home and abroad,sorts out the application scenarios of the eye control system,and summarizes and analyzes the corresponding design principles of the eye control system.Combining the physiological characteristics of smooth tracking with user behavior analysis,combining the physiological characteristics of the tracking process with specific scenes,forming a semantic mapping,and determining the numerical adjustment as the task purpose,thus completing an eye-control interaction framework based on smooth tracking.At the same time,through the basic framework of the eye control interactive system,we perfected and built an eye control interactive platform with Unity as the visualization medium and the Tobii eye tracker as the line-of-sight input.At the same time,the technical route of the development process was summarized.In order to further explore the interactive performance of smooth tracking as an interactive action in the eye control system,firstly,based on the optimal size of the interactive controls in the gaze state,combined with Fitz's law to infer the appropriate size of the interface elements used in smooth tracking,and then go further Explore the influence of the arrangement of interface elements on the interactive performance of the eye control system.After two rounds of experiments,a preliminary conclusion can be drawn that can be used as a theoretical reference for subsequent experiments,that is,the overall interaction efficiency of the system when the slider moves at a speed of 36 degrees per second and the orbital arrangement is left minus right plus form Higher.At the same time,when the adjustment value of the numerical value is in the center of the interface,the overall interaction efficiency of the system is higher.Subsequently,on the premise that the action design is complete and smooth,and can basically meet the interaction requirements,the experimental verification for the visual representation of the interactive interface elements was carried out.Finally,through analysis of variance,combined with SUS scale evaluation and standardized user interviews,the experimental results were further explained,and finally a new type of eye-controlled interactive action based on smooth tracking was summarized,and the visual interface elements of the interactive action The characterization was optimized and designed,and finally,under the premise of ensuring the efficiency of interaction,a parameter design of interface elements that more in line with the user's habits was obtained.
