Today’s VR systems rely heavily on goggle-generated visual displays to transport users to simulated worlds. But superthin, shape-shifting sheets worn as sleeves or built into other garments could provide gamers with tactile feedback that makes virtual realities more immersive.

The new device, described April 5 at the Materials Research Society spring meeting, contains a grid of tiny, inflatable bubbles, sandwiched between two soft, stretchy silicone films. When one of these bubble wrap–like sheets is placed against a user’s skin, inflating different air pockets by different amounts at different speeds can make a gamer feel like she’s been grabbed around the wrist or patted on the back. Some previously developed hand- or finger-worn devices have allowed wearers to feel or manipulate virtual objects.

But clothing embedded with smart silicone skins could make VR gaming more of a full-body experience. Each air pocket on the sheet is coated with a liquid metal sensor that tracks how much that bubble is distended, which helps regulate the device’s shape-shifting.

Those sensors also detect indentations in the bubbles, so these sleeves could work as touch pad game controllers, too, says study coauthor Matthew Robertson, a roboticist at École Polytechnique Fédérale de Lausanne in Switzerland. Currently, plastic tubes feed air into the device from an external pump. Read more from sciencenews.org…
