A sensing device for sensing a region provided on or in a surface having at least one region. The at least one region having printed therein or thereon coded data indicative of an identity of the at least one region, and visible information at least some of the information being at least partially related to the at least one region. The sensing device includes a sensor for sensing at least some of the coded data when the sensing device is placed in an operative position relative to the at least one region and generating indicating data. The indicating data is at least partially indicative of the identity of the at least one region and at least one of movement and a position of the sensing device relative to the at least one region. The sensing device includes a communicator configured to communicate the indicating data to a computer system.
