Controlling fatigue while lifting objects using Pseudo-haptics in a mixed reality space

In this paper, we aim to compose a mixed reality (MR) weight display system without the use of complex structures. We realize this system by modifying the visual movement of a handled object to evoke the Pseudo-haptic effect. To apply the system to an MR space, we introduce a method to compensate for the difference between the position of the actual object and the position of the presented image that occurs by modifying the visual movement. Furthermore, we investigate how this system affects the physiological reaction of the user by implementing the proposed method to control fatigue during object lifting. The results suggest that the system effectively eliminates the need for excess energy use and reduces fatigue during object lifting.
