<p>A communication system and method comprises endpoint devices (10, 11), each of which has one or more audio transducers and a touch screen. The devices (10, 11) are connected by a network (12) providing non-dedicated communication paths to servers (14, 15). An application (16, 17) is resident in each of the servers (14, 15) and has the ability to affect the image displayed on at least part of the screen. The server (14, 15) performs signaling for controlling an audio connection between the devices (10, 11). The touch screen is interactive and is able to initiate the audio connection. The application (16, 17) allows the screen or each screen of devices (10, 11) participating in the audio connection to display the path of consecutive measured positions of a pointer on the screen from one or more of the connected devices (10, 11). The touch screen is able to display an image supplied by a remote server or other apparatus after the audio connection has been initiated.</p> |
