Abstract

Data processing apparatus comprises an array of user-operable controls, the controls being adjustable by movement of a user's hand while touching a control; a detector for detecting when a user's hand is touching a control; a display screen for displaying respective screen icons associated with the controls; and a display processor, responsive to a detection that a user's hand is touching one of the controls, for altering the screen icon associated with that control.

We claim:  
     
         1 . Data processing apparatus comprising: 
 (i) an array of user-operable controls, said controls being adjustable by movement of a user's hand while touching a control;    (ii) a detector for detecting when a user's hand is touching a control;    (iii) a display screen for displaying respective screen icons associated with said controls; and    (iv) a display processor, responsive to a detection that a user's hand is touching one of said controls, for altering said screen icon associated with that control.    
     
     
         2 . Apparatus according to    claim 2   , said apparatus being audio processing apparatus and said array of controls relating at least in part to the control of audio processing parameters.  
     
     
         3 . Apparatus according to    claim 2   , in which said screen icon relating to a control displays, at least in part, an audio processing parameter associated with that control.  
     
     
         4 . Apparatus according to    claim 1   , in which said display processor is operable to change a display colour of at least a part of said icon associated with a touched control.
