Human temperature perception is not simply a thermometer reading, but a complex symphony orchestrated by nerve endings, signal transmission, and brain decoding. Our skin contains different receptors sensitive to cold and heat stimuli. When these receptors are activated simultaneously or sequentially, the signals undergo integration and interference during transmission to the central nervous system, sometimes even producing subjective perceptions that contradict the actual physical temperature, such as "hot/cold illusions." Understanding this phenomenon is the starting point for exploring the subtle gap between perception and reality. Our interactive exhibit, "Knowing Cold and Heat," uses a special metal tube (1200*650*1050mm) integrated with a precise temperature control system to translate this neuroscience principle into a direct sensory experiment. When you touch either end of the tube, you can clearly experience the preset sensations of cold and heat. However, when you try to touch the middle section, a fascinating puzzle arises: at the same point of contact, cold and heat signals seem to intertwine and compete; you might perceive cold first, or heat first, or even an indescribable mixture of temperatures. This sense of contradiction, experienced firsthand, vividly reveals the differences in the speed of neural signal transmission, spatial integration, and the "subjectivity" of the brain's interpretation. Our company is dedicated to transforming the body's internal, invisible mechanisms into interactive experiences that the public can personally explore. The core of designing exhibits like "Knowing Cold and Hot" lies in precisely controlling physical stimulus parameters to trigger specific, reflective perceptual phenomena. If you are also interested in this kind of science installation that guides visitors to "explore inward" and reflect on the reliability of their own perceptions, we can customize an exhibit specifically for you, jointly building a cognitive bridge connecting the objective world and subjective experience.
