META UNVEILS WRISTBAND FOR CONTROLLING COMPUTERS WITH HAND GESTURES

Summary from the TLDR newsletter

Meta's wristband reads the electrical signals that pulse through the muscles when people move their fingers. It uses a technique called electromyography to gather electrical signals from muscles in the forearm. These signals can reveal what people are about to do even before they do it. With enough practice, people using the wristband can control devices simply by producing the right thought.
