1. A relay device for providing communication between a sensing device and a computer system, the relay device including:

  • a first communications module for receiving first indicating data transmitted from the sensing device in a first format, the indicating data being sensed by the sensing device when it is placed into an operative position in relation to first coded data forming part of a first interface disposed on a first surface, the indicating data including a first region identity indicative of an identity of a region associated with the first interface;

    a processor configured to generate second indicating data based on the first indicating data; and

    a second communications module for transmitting the second indicating data in a second format to the computer system,wherein the sensing device is further adapted to store a sensing device identifier which is adapted to distinguish the sensing device from other sensing devices of the same type.
