MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202631123433 A) filed by Birla Institute Of Technology, Mesra on October 15, 2026, for Haptic Navigation System For Assisting Visually Impaired Users Using Ultrasonic Sensing And Haptic Navigation Language.
Inventors include Mr. Sahil Agrawal; Mr. Vivek Kumar Rai; Mr. Aryan Raj; and Dr. Debomita Ghosh.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A haptic navigation system (100) comprises a wearable belt apparatus (102), ultrasonic sensors (104) oriented toward the front, left, right, and ground, a control unit (106), and a vibration actuator array (108). A user device (110) receives a spoken destination, retrieves walking directions, and transmits encoded route commands to the control unit. The control unit evaluates sensor distance data to identify hazard conditions. A priority arbitration module (112) suppresses route-guidance vibration output when a hazard condition is detected and permits its resumption when the condition clears. A haptic navigation language module (114) associates route instructions and hazard indications with respective vibration patterns. A directional clearance evaluation module (116) compares lateral distances to recommend an avoidance direction. The belt delivers guidance through vibration without generating auditory or visual guidance output.
