Abstract:
1. A system for sensing and detecting spontaneous or localized changes in an electromagnetic field and generating an indication or message in response thereto, comprising: (a) a sensor configured to sense and detect a momentary and localized change in an ambient electromagnetic field and generate an Electro-Magnetic Field change detection signal in response thereto; (b) an Electromagnetic Peripheral Adapter or Electro-Magnetic Field typewriter interface circuit configured to detect said Electro-Magnetic Field change detection signal and generate a selected plurality of momentary communication state-change signals and an Electro-Magnetic Field typewriter Pointer signal encoded for communication with a computer; (c) a computer programmed to generate momentary communication prompts for playback or display and to receive said Electro-Magnetic Field typewriter Pointer signal in response to detecting said momentary and localized change; and (d) wherein said computer is further programmed to correlate a momentary communication state-change signal encoded in said Electro-Magnetic Field typewriter Pointer signal with a momentary communication prompt to identify a sensed indicia or command from said Electro-Magnetic Field change detection signal.
