Abstract:

A multiplicity of pressure-sensitive switching devices are mounted beneath a surface and a selected number are connected by circuit means through a programmer to at least one signal generating apparatus. When a pressure-sensitive switching device is closed, the signal generating apparatus is activated and a particular signal is produced. As a series of pressure-sensitive switching devices are closed as an individual moves across the surface, the signals produced will be coordinated with that movement. The programmer permits any pressure-sensitive switching device to be placed in circuit to generate any identified signal so that each pressure-sensitive switching device can be made to activate a particular signal. The programmer permits the signal generated when a particular pressure-sensitive switching device is closed to be changed. In an alternative embodiment, electronic switching means in the circuit will automatically place the pressure-sensitive switching devices in a different circuit to vary the signal produced when one or all of the pressure-sensitive switching devices are closed.
