Abstract: A computer input device is disclosed, including a base element arranged for resting on a surface, detecting device for detecting movement of the base element relative to the surface, communication device for communicating information about the movement to a computer, and a grip element connected to the base element in the direction of a connection axis. The base element is provided with a recess, and the grip element extends into the recess, where it is pivotably arranged relative to the base element and where it is prevented from rotating relative to the base element round its connection axis. There is also disclosed a base element, arranged for resting on a surface and connectable to a grip element to form a computer input device in conjunction therewith. The base element is provided with a recess adapted for receiving the grip element pivotably therein such that the grip element is prevented from rotating relative to the base element round a connection axis thereof.
