In this project, we explored how to add haptics to walls and other heavy objects in virtual reality. Our main idea is to prevent the user’s hands from penetrating virtual objects by means of electrical muscle stimulation (EMS). Figure 1a shows an example. As the shown user lifts a virtual cube, our system lets the user feel the weight and resistance of the cube. The heavier the cube and the harder the user presses the cube, the stronger a counterforce the system generates. Figure 1b illustrates how our system implements the physicality of the cube, i.e., by actuating the user’s opposing muscles with EMS.
