Method and apparatus for sensing spontaneous changes in a localized electromagnetic field and method for use

A method for sensing, detecting and using spontaneous changes in a localized electromagnetic field, comprising:

• (a) providing a sensor configured to sense and detect a change in an ambient electromagnetic field and generate a change detection signal in response thereto;
• (b) sensing a momentary and localized change in an ambient electromagnetic field and (c) generating an Electro-Magnetic Field change detection signal in response thereto;
• (d) providing an Electromagnetic Peripheral Adapter or Electro-Magnetic Field typewriter interface circuit configured to detect the 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;
• (e) detecting said Electro-Magnetic Field change detection signal and generating a selected plurality of momentary communication state-change signals and an Electro-Magnetic Field typewriter Pointer signal encoded for communication with a computer.

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 spontaneously, wherein said sensor has at least four pre-defined Electro-Magnetic Field threshold levels;
• (b) an Electromagnetic Peripheral Adapter or Electro-Magnetic Field typewriter interface circuit configured to receive and process said Electro-Magnetic Field change detection signal and generate a selected plurality of momentary communication state-change signals encoded within an Electro-Magnetic Field typewriter Pointer signal encoded for communication with a computer;
• (c) a computer programmed to receive said Electro-Magnetic Field typewriter Pointer signal and generate momentary communication prompts for playback or display 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.
