The Logitech Cube is a wireless input device that assumes the functionality of a regular computer mouse. Numerous intelligent apps expand its range of utilisation: it can, for instance, control presentations when lifted up and held in the hand. When the user strokes along the surface, it scrolls rapidly and fluently through documents and websites. The design is monolithic, compact and geared to mobile use. With its rounded edges and soft surfaces, the device fits comfortably in the hand as well as in any pocket or bag.
