Facebook is working on a wearable wrist sensor linked to augmented reality glasses that would allow you to type on any surface with a simple tap or snap of your fingers The social media giant said the device would be able to control its augmented reality glasses - currently in development and expected to be launched this year WHAT'S THE DIFFERENCE BETWEEN AR AND VR? Virtual reality is a computer-generated simulation of an environment or situation It immerses the user by making them feel like they are in the simulated reality through images and sounds For example, in VR, you could feel like you're climbing a mountain while you're at home In contrast, augmented reality layers computer-generated images on top of an existing reality AR is developed into apps to bring digital components into the real world For example, in the Pokemon Go app, the characters seem to appear in real world scenarios The device, currently without a brand name, is a big step up for Facebook, in what is expected to become a hotly contested market for augmented reality devices. Wearers of the wrist band would be able to interact with the virtual world through finger movements, the company said in a blog post on the new technology The AR-supporting wearable device will also be capable of detecting nerve signals to interpret complex hand gestures and moves, providing full control of displays EMG: ELECTROMYOGRAPHY Electromyography, also known as EMG, involves the interpreting of nerve signals in the arm.
