Patent US6506148B2, "Nervous system manipulation by electromagnetic fields from monitors," describes a method for influencing the human nervous system by using weak electromagnetic fields emitted by computer monitors or TV sets. Pulsed images on screens can create frequencies (around ½ Hz or 2.4 Hz) that induce sensory resonance.
Key Aspects and Effects:
-Purpose: The patent claims that, by pulsing images on a monitor, the electromagnetic fields emitted can cause physiological effects.
-Effects on Nervous System: Observed effects include eyelid ptosis, relaxation, drowsiness, pressure on the brow, visual patterns (dark purple/greenish-yellow), a tonic smile, stomach tension, diarrhea, and sexual arousal, depending on the frequency.
-Mechanism: The technology relies on exciting a "sensory resonance" in the viewer through modulated, pulsed video or RF signals.
-Application: The technique can be implemented through a simple computer program to pulse images on a display.
This 2003 patent by Hendricus G. Loos has often been cited in discussions regarding user experience and, in some contexts, conspiracy theories surrounding mind control.
