Method of enabling a device to be controlled via a printed control interface

A system for enabling at least one function of a device to be controlled, the system including

• a printed control interface control interface comprising user control instructions relating to the device and coded data indicative of an identity of the control interface and of coordinates of a plurality of locations on the control interface;
• and
• an optical sensing device for initiating an operation relating to at least one parameter of the control instructions, the sensing device being configured to:
• sense at least some of the coded data when placed in an operative position relative to the control interface;
• generate indicating data using the sensed coded data, the indicating data being indicative of the identity of the control interface and the position of the sensing device relative to the control interface;
• and
• transmit the indicating data to a computer system, thereby enabling the computer system to identify the at least one parameter relating to the control instructions and control the device accordingly.
