Auditory and visual technologies have been fully developed and utilized, while as an emerging field, tactile sense is a research direction with great potential. As a type of unique human sensory channel, tactile sense has unique advantages. It can convey information about maximum joints in physiological structure of human body, such as hardness, texture, shape, size, and temperature, which cannot be transmitted by visual and auditory senses. Additionally, the tactile sense is fast and accurate, thus, it performs well in some special situations, such as supergravity scenarios, high-speed rotating scenarios, or very noisy environments. The design of vibrational tactile coding is an important way to develop tactile devices and achieve a better human computer interaction. Haptic coding has several defects. It is used in narrow application scenes and conveys unclear meaning. Compared with the mature development of vision and hearing, it is necessary to further design the vibration haptic coding patterns to overcome these defects. Research on information transmission of tactile sense is very meaningful, for example, it offers convenience for special groups such as people with visual impairment or workers engaged in their education. It provides a navigation service for visually impaired people by changing the vibration frequency and vibration intensity of a blind vest.
