A sensing device for interaction with a surface, said sensing device having automatic mode selection, said sensing device comprising: an image sensor for imaging the surface and generating image data; a motion sensor configured for determining one or more relative position changes of the sensing device; a processor configured for: receiving the image data; and automatically selecting, using said image data, either an interaction mode or a cursor mode for said sensing device; and communication means for transmitting either interaction data or cursor data to a computer system, dependent on said selected mode, wherein said processor is configured to: select the interaction mode and generate interaction data from the image data if said image data indicates that said sensing device is interacting with a first surface having a position-coding pattern disposed thereon, said interaction data being indicative of at least one absolute location of the sensing device relative to the surface; and select the cursor mode if said image data indicates that said sensing device is interacting with a second surface lacking a position-coding pattern, said cursor data being indicative of said one or more relative position changes of the sensing device.
