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

摘要

A method of enabling a device to be controlled via a printed control interface is provided. The method includes the steps of: positioning an optical sensing device in an operative position relative to the control interface; sensing coded data on the control interface; generating indicating data in the sensing device 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 transmitting the indicating data to a computer system, thereby enabling the computer system to identify a parameter relating to the control instructions and control the device accordingly.
