What is "body sensation"?

Somatosensory, or somatosensory, is a general term for touch, pressure, temperature, pain, and proprioception (feelings about muscle and joint position and movement, body posture and movement, and facial expressions).

Somatosensory is a concept opposite to special sensations. These different somatosensory patterns arise from different types of receptors. In mammals, the ascending neural pathways of somatosensory originate from receptors in different parts of the body;

The receptors pass through the posterior column, medial lemniscus pathway, anterior spinothalamic tract, anterior spinal cortical tract, and posterior spinal cortical tract, and finally Somatosensory cortex of the postcentral gyrus of the cerebral cortex.

Somatosensory can be classified into: skin sensation, motor sensation and visceral sensation. Among them, the first two are the types that are relatively well understood at present. Visceral sensation conveys information about the inside of a body cavity, such as abdominal pain.

Extended information:

Somatosensory technology generally requires the use of somatosensory devices such as handles, foot straps, sensor caps, etc. to capture human body movements and expressions, such as the most well-known Wii game.

Just by moving your hands and feet, the human body's movement threads can be captured through the recognizer, such as human body motion tracking and analysis technology, which can directly capture people's facial expressions and body movements from ordinary web cameras.

The current somatosensory technology is still in the development stage, but it has been widely used in games, film and television, medical care, etc. With the changes of the times and the development of science and technology, the application fields of somatosensory technology will also be further expanded. .
