description	This invention relates to a navigation tool for connecting to a display device, comprising at least two sensor elements having known positions relative to each other, each sensor element being coupled to detector means for recording a change in a predetermined parametre and timing means for determining the time of change at each sensor element and calculating means for calculating the direction and speed of the recorded changes based on the relative positions of the sensor elements and the duration between the recorded changes.
