Research On Interactive Experience Evaluation Based On Gesture Recognition VR System

In recent years,with the rapid development of head-mounted VR equipments for the consumer end market,the interactive technologies which are available for head-mounted VR equipments are applied more extensively.The non-contact gesture recognition of intellisense is popular because it is flexible and easy to learn.The head-mounted VR system has become a high potential development direction of close-range interactive scene.This thesis mainly research the evaluation of interactive experience in gesture recognition system and it uses the gesture interaction performance measurement and the subjective and objective evaluation of arm fatigue.Firstly,gesture recognition is the key point of human-computer interaction.In the interactive performance measurement in gesture recognition VR system,it is based on the classification of the common interactive gestures of users and quantitatively evaluates the interaction performance of different interactive gestures by contrasting and testing their recognition efficiency,mistake times and completion time.Secondly,this thesis learns exercise-induced muscle fatigue researches in the field of modern medicine and human-computer interaction.It starts from the biological theories of muscle contraction and fatigue and then determines the research method of combining subjective and objective.Meanwhile,it follows the research idea of bottom-up and user-centered approach and uses real interactive situations to decompose the most common click behavior in gesture interaction.Based on the difference of muscle contractions in static process,it studies the influences of hover operations on hand fatigue.Finally,it is based on the gesture recognition performance measurement of VR system and the subjective and objective evaluation of arm fatigue,proposing the synthetic evaluation model of interactive experience of gesture recognition VR system and testing it.This thesis considers the recognition efficiency constraints of gestures and real interactive situations needs and gets the comparative evaluation results of interactive performance of all kinds of typical interactive gestures,understanding the accumulation of hand fatigue in each steps of the operation.It makes the research results have more universality,applicability and expansibility.It obtains the data of performance measurement gesture recognition and the trend of static fatigue,building the synthetic evaluation model of interactive experience of gesture recognition VR system.It can provide reference for interactive design of gesture recognition VR system.
