HapticWave, an Oculus research project, uses a metal plate on a ring of electromagnet actuators to send vibrations to your hand to let you feel virtual objects. A headset and audio help the illusion along, says Ravish Mehra, a research scientist at Oculus.
With this tech, your hand would stand in for your entire body, says Ravish Mehra, a research scientist at Oculus. If someone in a video game is creeping up behind you, you might feel vibrations at the base of your palm. If you're in an educational experience exploring the world of dinosaurs, your entire hand might vibrate with each step. "Our hope around this project was being able to generate this extrasensory input so users can be more perceptive and more believable of virtual objects," Mehra says.
There has been some recent demos created to showcase this new tech and will be showcased later this month at the Siggraph computer graphics and interaction conference. http://s2016.siggraph.org/
