Title:
THREE DIMENSIONAL ORIENTATION AND DIRECTION INDICATOR AND APPARATUS FOR PROVIDING INFORMATION ON A DIRECTION
Document Type and Number:
WIPO Patent Application WO/2010/112877
Kind Code:
A3
Abstract:
A device for indicating a direction or axis in three dimensions to a user, comprises an indicator member (10, 11) configured to indicate a direction in any three dimensional direction,- a static member (12) for mounting the indicator member; and an actuator arrangement (12, 14, 15) configured to urge the indicator member to rotate relative to the static member in any angle about a single point of rotational symmetry. A direction indicating arrangement calculates an angle in three dimensions for indicating a direction and comprises a drive arrangement (13, 14, 15) that drives a pointing device (10, 11) to point in the calculated direction. An apparatus for providing information on a location in a direction comprises a pointing device comprising a mount and a direction indicator moveable by a user to point in a direction in three dimensions; a detection arrangement for detecting the orientation of the direction indicator; a processor programmed to determine the direction using the detected orientation; and a display for displaying information on the direction.
