1. A handheld device (10), having a position sensing means (14) on a rear side (12) of said device (10) for reading position coordinate data (x, y, z) while manually moving said device (10) rear side (12) on a working surface (22), a display screen (20) on a front side (21) of said device (10), said position sensing means (14) controlling a cursor (24) on said display (20), by further comprising:

  • a device-to-cursor position coordinate data (x, y, z) conversion means provided to process the device coordinate data (x, y, z) in accordance to a preset ratio for scaled cursor (24) coordinate data (x, y, z), thus defining a cursor (24) movement which is in scaled correspondence with the device movement; and

    a cursor (24) controller means for a cursor (24) movement across said display according to the scaled cursor (24) coordinate data (x, y, z);

    whereby the cursor (24) moves on the digital display concurrently as the device is manually moved across the surface in scaled correspondence with the movement pattern of the device.
