Virtual reality can transport users anywhere from alien worlds to medical simulations. But adding a growing number of hardware accessories to VR headsets could create an even more realistic experience.

Soon, you might be able to type comfortably in virtual reality or feel bullets in a game with a haptic suit. Researchers at Facebook are working on a virtual floating keyboard that lets you touch any surface to type. Other devices will bring users even closer to virtual worlds, experts say.

“The more input devices VR supports, the more productive VR experiences become,” Edward Haravon, co-founder of VR/AR consultancy Get Real, said in an email interview. “Whether it’s replicating tasks currently reserved for 2D desktop platforms, or reducing friction for something as simple as logging in, the more press-and-play a VR headset can be, the more people will use it to improve their productivity.”

One of the hottest categories in the world of VR accessories involves wearables like flex sensor gloves and even full bodysuits. Teslasuit, for example, is working on a device that looks like a scuba suit and allows you to “feel” bullets when you get shot in a game.
