SpaceCat is an elastic desktop 6DOF input device. It has been shown that this could be beneficial to virtual scene navigation.

A growing need for six-degrees-of-freedom (6DOF) input devices is partly due to the rapid development in 3D computer graphics. With 3D computational power at low cost, new software and applications become widespread. These are potentially popular products, such as 3D Internet, 3D window managers, 3D visualisation and animation software, computer games, and interactive television. Already, many input devices offer multiple degrees of input freedom, e.g. data gloves, motion-tracking sensors, and desktop input devices like the SpaceBall from 3DConnexion. However, these devices only fulfil a sub-set of criteria stated as necessary for their success. Pursuing a solution fulfilling more of these criteria, this paper presents SpaceCat, an elastic desktop 6DOF input device offering a) range of motion adapted to the hand's movement, b) elastic suspension providing rich sensory feed-back for fast and precise manipulation, and c) user selection of position or rate control. It has been shown that such devices (offering a-c) are beneficial to virtual scene navigation. Generalising that result, this paper shows that such devices also may benefit 3D object manipulation.
