The cross-sensory experience of
torso sex dolls relies on the integration of the head. When the temperature sensing system transmits a body temperature of 36.5?C, the
sex doll head must synchronize its exhalation: exhaling 35?C moist air (98% humidity), matching the vibration frequency of the vocal cords to the rise and fall of the chest, and even synchronizing the fluttering of eyelashes with breathing. Any error in this multi-channel synchronization greater than 0.3 seconds can trigger cognitive dissonance in the brain. The latest solution uses quantum cascade lasers to monitor the entire body, with the head acting as a central processor to adjust each module in real time, creating an immersive, closed-loop illusion.
