ELECTRICAL MUSCLE STIMULATION HAPTICS for Virtual Reality
Virtual Reality using electrical muscle stimulation. The main idea is to prevent the user’s hands from penetrating virtual objects by means of electrical muscle stimulation (EMS).
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 counter force the system generates.
Exporing how to add haptics to walls and other heavy objects in virtual reality.
When a user tries to push such an object, our system actuates the user’s shoulder, arm, and wrist muscles by means of electrical muscle stimulation, creating a counter force that pulls the user’s arm backwards.
The devices accomplishes this in a wearable form factor.
In theur first user study, participants wearing a head-mounted display interacted with objects provided with different types of EMS effects. The repulsion design (visualized as an electrical field) and the soft design (visualized as a magnetic field) received high scores on “prevented me from passing through” as well as “realistic.”
In a second study, they demonstrate the effectiveness of their approach by letting participants explore a virtual world in which all objects provide haptic EMS effects, including walls, gates, sliders, boxes, and projectiles.

“We believe that computer science and mechanical engineering are about to unite. In the future, users will solve mechanical problems by digitizing the involved objects using 3D scanners, solving the problem in the digital domain using the means of computer science, and converting the result back to the mechanical domain using a 3D printer. This will allow solving mechanical problems with the effectiveness and efficiency of computer science, including the ability to scale massively.
This will not only change mechanical engineering, but also allow computing to reach its next phase, which is to merge into matter itself, where the physical matter of objects will also perform the computation, rather than separate micro controllers.”
