<p>An interfacing device and method for controlling and accessing information and communication services and applications are described (10, 11, 12, 17, 18). The method relates to a common virtual canvas linking the display space of a large, central public display (17) with the private work and display spaces of ambulatory, high-resolution touch-activated devices, such as lap-top controllers (10). Instead of actually transferring information from one lap-top controller (10) to another or to the public space, with a lap-top controller (10) the users are actually controlling the permission of others to access certain information transmitting the information to the set-top box (10, 11, 12, 17, 18). Therefore, the user is actually controlling the state of their collective virtual canvas by manipulating permissions which determine each user's view (17) of multimedia information stored in central network-based servers.</p> |
