{{:pradeep_etal_navigation.png?1000| Navigation System}}

The goal of the navigation system is to recognize the location of the current user, create a path to a specified goal location, and guide the visually impaired user through obstacles and traversing paths.


vision processing algorithms



This is accomplished by a stereoscopic camera, which are used to create a map of the environment using the S.L.A.M. (Simultaneous Localization And Mapping) technique.
In addition, the system also creates a traversability map for the user local surrounding, to ensure safe passage.

The system then activates a tactile interface consisting of micro-vibration motors to provide cues for taking evasive action.
