An experimental prototype of a hand-gesture controller for computing devices from Meta Platforms. Introduced in 2025, the wristband enables a person to open an application, control the cursor and literally "write in the air" instead of using a mouse. Even thoughts are said to be able to move the cursor, as amazing as that sounds. See
neural interface.

Meta is expected to add this feature in the coming years and hopes it will be used to command its smart glasses as well. (Image courtesy of Meta Platforms, Inc.)
