ABSTRACT:
A pointing device having a sensor for directing towards an icon displayed on a display screen. The sensor generates a sense signal indicative of an attribute of the icon. An audio generator generates, in dependence on the sense signal, an audio signal for subsequent detection by the microphone of a telephone. Also, a system includes the pointing device, for remote selection of one or more options in a data processing apparatus. The system is capable of receiving a call from a telephone; allocating a teletext page in a television signal in response to the call; associating each option with an icon; writing each icon to the allocated teletext page; associating each icon with an audio signal; and, activating each option on receipt of the corresponding audio signal from the telephone.
