Abstract
A device comprises a first part (1) which has user input means (10) and comprising a three-degrees-of-freedom orientation sensing system (11) for determining a three-degrees-of-freedom orientation (01) of the first part (1) with respect to a reference coordinate frame (XYZ) defined by the earths gravity field (Fg) and magnetic field (Fm). A second part (2) comprises a display (20) for displaying orientation information (OI) on a three-degrees-of-freedom orientation (02) of the second part (2), and sensing means (21) for sensing an one-degree-of-freedom or a two-degrees-of-freedom orientation of the second part (2). Further, are provided means (5) for calculating the three-degrees-of-freedom orientation (02) of the second part (2) from the three-degrees-of-freedom orientation (01) of the first part (1) and the one-degree-of-freedom or the two-degrees-of-freedom orientation of the second part (2), and means (6) for generating the orientation information (01) in response to the calculated three-degrees-of-freedom orientation (02) of the second part (2) to obtain correct display of the orientation information (01) independent on an orientation of the second part (2) with respect to the first part (1).
