<p>The input device comprises a support (1) and a movable, hollow handle (2). A column (3) extends from the support into the handle (2), and an elastic coupling comprising a plurality of springs (5a, 5b, 5c) is arranged between the upper end of the column (3) and the handle (2). The position of the handle is determined by a measurement of the inductances of the springs (5a, 5b, 5c). The springs (5a, 5b, 5c) and measuring circuitry are fully enclosed by the handle and thereby protected by it. A plurality of stops within the handle restrict the movements in all degrees of freedom. <IMAGE></p> |
