Multisensory Interaction Design And User Experience Of Virtual Reality Exercise Bike System

With the continuous development of technology,virtual reality is gradually integrating with various fields.In the field of sports,the characteristics of virtual reality immersive sports experience are increasingly attracting people to participate.However,in the virtual reality environment,the design of the multisensory channel is closely related to the user experience factors such as immersion and vertigo,and it is necessary to analyze and design the multisensory channel reasonably.Aiming at the problem of multisensory channel interaction design and its influence on user experience(UX)in virtual reality sports situation,through studying the latest theoretical achievements of visual,auditory and tactile design in virtual reality by domestic and foreign scholars are studied.,the characteristics of multisensory channels in virtual reality are summarized.In this way,the design scheme of visual,auditory and haptic channels are proposed to be used as the theoretical basis for design,and in order to evaluate the UX of sports in virtual reality sports,a model framework for its UX evaluation is proposed,which provides a new method to analyze the effects of multisensory channel.Taking the multisensory channel interaction design of virtual reality exercise bike system as case to carry out specific research.Using data mining,questionnaires and user interviews to understand the emotional orientation characteristics of users on traditional exercise bikes,and to discover the problems and experience deficiencies encountered by users when using exercise bikes,as well as to analyze the design points in designing multisensory channel interaction to achieve functional requirements.According to the functional requirements,the information architecture of the system is established,and the interaction process is analyzed.Combined with the design principles of multisensory channels,the visual,auditory and tactile channels of the system are designed.The prototype of virtual reality riding system is designed and implemented by using Unity3 D engine and sensor technology,and the proposed multisensory interaction channel design method was implemented.Record ECG and power data of participants in real time using physiological feedback device and pedal power meter during the experiment,and the different effects of visual,auditory,and airflow haptic channels on the UX are analyzed.The experimental results show that the overall user experience of the virtual reality exercise bike prototype system is well,the multisensory channel feedback method with visual,auditory and airflow touch can significantly enhance the presence of the system,improve emotional immersion and reduce anxiety,meets the design requirements of the virtual reality exercise bike system for multisensory channels,also verifies the availability of the multichannel interaction mode of the system.
