Abstract
An interactive system, comprising a local controller (8) operable to control data flow to and from at least two local handsets (11,22) for generating data. The local controller (8) includes a memory (28) for storing data and a processor. A central controller (1) is connectable to the local controller, and a display (12) is provided for displaying data locally from the central controller and the local controller. The local controller (8) stores data generated by each local handset and selectively transfers stored data to the central controller (1). A handset for use in the system comprises a transmitter and a receiver (9) for transfer of data between the handset (11,22) and the local controller and input means to input data for controlling the output of the display via the local controller is input to the local controller by means of a cursor control (33) laterally movable over a plane (36) and a sensor (38,41) for sensing a position of the cursor control within the plane (36) and causing a cursor on the display (12) to take up a similar position. A method of operating the system comprises broadcasting first data from the central controller to which the local controller responds by …
