Research On Interactive Technology Based On Elbow Joint Movement Angle

In recent years,with the development of wearable devices,human body research has received more and more attention.Limb interaction has direct,natural,and sensitive characteristics,which can replace traditional interactive input operations.Using the elbow joint motion angle to input information to control the computer or smart device can increase the intelligence and naturalness in the interaction process.So far,no researchers have systematically studied the control accuracy and comfort zone of human elbow joint motion angle.Therefore,in this paper,the control method,cognitive science,computer science,behavioral science and other theoretical methods are used as guides to evaluate the comfortable area and controllable accuracy of the human arm elbow joint angle.The user's ability to control the angle of motion of the arm elbow.Based on the experimental results,we summarized the comfort zone and control accuracy of the elbow joint motion angle of the arm,and applied the noise reduction function to reduce the jitter of the arm and improve the control performance.We also designed a series of technical prototypes that used elbow joint motion angles as input,and analyzed the interactive use schemes of the technical prototypes.This paper is organized as follows:(1)To evaluate the comfort zone and control accuracy of the elbow joint inclination,first,use a limb detection device to detect the movement of the arm elbow joint inclination,establish a model to realize the real-time observation of the angle value of the elbow joint inclination on the computer,and then write the experimental interface and data Collect functional programs,organize experimenters to conduct experiments,and collect experimental data for statistical analysis to evaluate the comfort zone and control accuracy of the elbow joint inclination.(2)To evaluate the comfort area and control accuracy of the elbow joint swing angle,first,use the limb detection device as a medium to perform motion detection on the arm elbow joint swing angle,plan the detection results by establishing a model,and achieve a stable and accurate display on the computer interface real-time angle value of the elbow joint swing angle,then write the experimental program to realize the visual experimental interface and collect the experimental data,and then conduct the experiment to obtain the experimental data,and analyze the experimental data using statistical methods to evaluate the elbow joint comfort zone and control accuracy of the swing angle.(3)Due to the existence of physiological tremor,we applied two noise reduction functions to improve the control performance and stability.We collected and analyzed experimental data,and analyzed the control performance and stability of the elbow joint motion angle through data comparison.(4)Based on the research conclusions of the elbow joint motion angle,we propose six technical prototypes that use elbow joint angle for interaction to guide how to reasonably select the comfortable area and control accuracy of the human elbow joint angle to design the interaction technology.
