Usability study of auditory feedback and visual feedback in an immersive virtual assembly system

Abstract

In this paper, we evaluate the usability of auditory feedback and visual feedback in an immersive virtual assembly system which is designed for mechanical engineering teaching. We choose task accomplished or not, rate of task accomplishment, time of task accomplishment, lostness, and user subjective satisfaction as the usability measurement indicators. Usability tests are carried out under four conditions: no feedback, visual feedback, auditory feedback and multichannel feedback. Experimental results show that multichannel feedback and visual feedback are more effective to virtual assembly system. Furthermore, we select multi-channel feedback in learning effect experiments, and compare the immersive virtual assembly training with real assembly environment training. The experimental results show that virtual assembly training with multi-channel feedback has obvious learning effect. but is significantly worse than real assembly training, and the time of virtual assembly training is significantly higher than that of real assembly training. The research results of this paper have certain guiding effect on the design and application of virtual assembly system.
