Claim:
A method of enabling at least one function of a telephone to be controlled, the telephone being operative to perform the at least one function in response to at least one command from a computer system, the method including the steps of: providing a control interface containing information relating to the at least one function, the control interface including coded data indicative of an identity of the control interface and of at least one reference point of the control interface; receiving, in the computer system, indicating data from a sensing device regarding the identity of the control interface and at least one of a position and a movement of the sensing device relative to the control interface; and effecting, in the computer system and from the indicating data, at least one operation relating to the at least one command, wherein the sensing device comprises: (a) an image sensor adapted to capture images of at least some of the coded data when the sensing device is placed in an operative position relative to the control interface; and (b) a processor adapted to: (i) identify at least some of the coded data from one or more of the captured images; (ii) determine an orientation, within the captured images, of at least some of the coded data; (iii) decode at least some of the coded data; and (iv) generate the indicating data using at least some of the decoded coded data.
