Can manipulating control-display ratio dynamically really work in changing pseudo-haptic weight?

Abstract

Due to the limited hardware available in virtual reality, such as VR controllers or simple motion capture devices, users will need more tactile feedback, like the weight of virtual objects. Pseudo-tactile feedback, such as the control display (C/D) ratio manipulation method, is considered a standard method to simulate weight perception. In past studies, this method was basically used in a static environment, and the C/D ratio was usually determined initially. Can this method still work if the C/D ratio changes in dynamic usage scenarios? In a series of experiments, we tried to answer this question. We proved that the dynamic change of C/D ratio could simulate the weight change and improve the sense of embodiment through another hand redirection method.
