1. A method for developing different audible signals for different associated contacts made by a pointing device with a touch-sensitive surface of a computer input and cursor manipulation device, said computer input and cursor manipulation device having a non-mechanical electronic switch, actuated by contact of a pointing device with the touch-sensitive surface, to thereby emulate an audible mechanical switch, said method comprising the steps of:

  • (a) developing an electrical signal in response to contact by the pointing device with the touch-sensitive surface, the electrical signal indicating actuation of the non-mechanical switch;

    (b) storing associated electrical signals for subsequent sequential recall from a memory which stores said electrical signals as a touch function sequence;

    (c) comparing a touch function sequence stored in the memory with a plurality of preselected touch function sequences, to identify which preselected sequence matches the stored touch function sequence, each of which is associated with a certain audible response signal;

    (d) transmitting to a sound producing device the audible response signal associated with the identified preselected touch function sequence; and

    (e) activating said sound producing device by the audible response signal to cause the sound producing device to generate a corresponding audible response.
