A Pointer That Gives You Room to MoveThe Loop pointer lets you control your computer without the constraints of wires or surfaces. Time to get animated.

The so-called "air mouse" that supposedly lets you control your laptop and, thus, your sales presentation from anywhere in the room is a tech concept that never really gelled.

By employing the simple principle that a large ring is easier to hold and manipulate in open space than an in-hand mouse, the Loop brings a level of ease of use and sensitivity to controlling a PC from a distance.
