3D navigation device for navigation in 3D representation of display device e.g. computer monitor, includes scanning unit for detecting translatory movement of housing over substrate in two dimensions

摘要

A device for 3D navigation has a housing (1) provided on the bottom face with a first scanning device (2) for detecting a translatory movement of the housing over the substrate in two dimensions, and a first input unit (4) with two degrees of freedom, the two units being arranged on the surface so that they are movable during guiding of the housing over the substrate by the fingers of the hand. A second scanning unit spaced from the first on the bottom face of the housing is provided for detecting translatory movement of the housing over substrate in two dimensions. An Independent claim is given for a method for 3D navigation in a 3D representation of a display device.
