The processor may receive input data. The processor may enhance the image based upon the angle and the depth information. The processor may determine “directional saliency”, “saliency at rest” and “saliency in motion” of the enhanced image of the scene to provide situational awareness and generate a virtual graph with a grid of nodes. The processor may probe each node in order to check whether or not the point corresponding to said node is on a floor and determine the shortest path to a destination in the virtual graph by only considering the points on the floor. The processor may convert the description of the shortest path and the scene into one or more of audio or Braille text instruction to the user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for indoor situational awareness and navigational aid for the visually impaired user","description":"A system and method for providing indoor situational awareness and navigational aid for the visually impaired user, is disclosed.
