For example, one of the keys houses the W, the S, and the X, but with a combination of button presses, users can also access numbers and symbols, such as "2" and "@", all from the same key. Combining multiple functions into a single set of keys means a user's finger has to travel less across the keyboard, translating into faster, more intuitive typing. A combination of magnets, sensing zones, and custom hardware inside each key allows the TextBlade to determine which letter is being pressed.
