Velvet texture

Interacting through models to understand that human tactile perception of the outside world is relative. The exhibit features three sets of circular wire mesh with different densities designed. When we put our hands together and gently rub the steel wire mesh with our palms, we will have a feeling similar to touching velvet. Through experiencing the exhibit, everyone can realize that human tactile perception of the outside world is relative, and understand the phenomenon of tactile illusions. Target audience: Adolescents aged 6-15 years old. Display format interactive model device operation instructions (audience experience) 1 Close your eyes, hold the wire mesh with both hands, and touch the metal mesh with different forces and speeds; 2. Search for a smooth and silky feeling, and understand the phenomenon of tactile illusions. Description of the internal connections between storylines and exhibits, including the human body's operating system and tactile illusions.

Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Touch refers to the perception of temperature, humidity, pain, pressure, vibration, and other sensations that are received by nerve cells distributed throughout the body's skin. Everyone has many nerve cells on their fingers, and when their hands come into contact with steel wire, a pressure is generated. After the contact, the pressure has not completely disappeared. Then, when the hand slides, another wave of pressure is transmitted, creating a tactile illusion. Even touching the steel wire can feel a feather like smoothness. Reference materials.
