Abstract
The present invention relates to a device (20) for providing haptic effects on a haptic surface. To enable a simple but accurate determination of the position, orientation and/or pose of an object positioned on the haptic surface the proposed device comprises a haptic surface (22), a number of haptic actuators (24) provided in or close to the haptic surface, a control means (26) for controlling said haptic actuators to provide a haptic effect in their proximity on the haptic surface, a sensing means (28) for sensing the actuator current and/or actuator voltage per actuator or group of actuators, and a processing means (30) for processing the sensed actuator current signals and/or actuator voltage signals by separately determining a characteristic of said actuator current signals and/or actuator voltage signals and generating pressure indications from the determined characteristic, said pressure indications indicating the amount of pressure at the respective actuator or group of actuators.
