Typing with a virtual reality headset is about to get easier thanks to a new invention that analyses the vibrations in your bones.

Using a keyboard in VR is tricky because you can’t really see where your fingers are landing. The new TapID gadget is a wristband with two motion sensors, one worn on each wrist, according to researchers who recently published a paper on their invention. The device detects taps from each of the user’s fingers individually.

“Right now, most VR users use a handheld controller that works a bit like a laser pointer,” Scott Camball, a telecommunications and teleconferencing enthusiast, said in an email interview. “They have to point at each letter on the virtual keyboard, and it can take a really long time to type things. That works for video games, but not for work-related tasks. TapID would allow users to have a virtual workspace with large screens without the bulk of a desktop computer.”

TapID works by analyzing the vibrations through your skeletal system using a machine learning algorithm. In VR environments, users can type on a virtual keyboard or interact with virtual objects on a surface using their fingers.
