Spending time in virtual worlds is lots of fun. With haptic feedback, you get an even more amazing experience. Haptics for VR Walls explores the idea of adding haptics to heavy objects in virtual reality. For instance, when you push an object, your muscles are electrically stimulated to create a counter force.
The system consists of a laptop that runs the VR experience and a muscle stimulator in a backpack. Pedro Lopes, Sijing You, Lung-Pan Cheng, Sebastian Marwecki, and Patrick Baudisch at the Hasso Plattner Institute are behind this project. The virtual environment had walls, gates, boxes, and projectiles that all had haptic EMS effects.
