Researching and development for blind navigation service based on Haptic are helpful with visually impaired in auxiliary guidance and improving quality of life. Firstly

the theory which is a set of spatial cognition model are compared

trying to quote a framework about spatial cognition to explain the blind cognitive status at meso-small scale. And then

summarized the latest research progress of blind navigation service based on Haptic

it is found that the currently blind navigation system is developing vigorously

the visually impaired needs to travel have to solved from the technical level

However

it still faces great challenges both at the theoretical level and in the practical application

the navigation service with the blind has a certain gap between existing technology and actual demand.
