Asmr (autonomous sensor meridian response), translated as "spontaneous perceptual meridian response" in Chinese, is a new word used to describe perceptual phenomena, which is characterized by a unique and pleasant feeling on the skull, scalp, back or other parts of the body through visual, auditory, tactile, olfactory or perceptual stimulation.

The anchor uses ASMR voice controller to induce sound through sleep aid sound effect. Through the live broadcast, it can be clearly seen that many videos and sounds will be recorded in the recording and recording equipment by the creators in the form of whispering or gentle conversation.

For example, a descriptive dialogue is conducted in a way similar to intention guidance, and scenes such as haircut, massage, seeing a doctor, and ear plucking are experienced. Although these virtual scenes are played by video creators, people who watch or listen to videos will trigger the ASMR effect: relieving insomnia, anxiety, or stabilizing restless emotions.

Some online discussion groups, such as Perception Paradise established on Yahoo platform in 2008 and Unknown Perception Blog founded by Andrew MacMuiris in 20 10, aim to provide a platform for learning more about perception by sharing opinions and personal experiences.
