MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202621027722 A) filed by Sage University, Indore, Madhya Pradesh, on March 9, for 'system and method for assistive navigation.'
Inventor(s) include Ms. Sakshi Agrawal; Dr. Satyendra Sharma; Prof. Megha Jat; Shivani Mishra; and Shivam Kushwah.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "A system (100) for assistive navigation comprises a pair of imaging devices (102) configured as a stereo camera pair, an inertial measurement unit (104) comprising a three-axis gyroscope and a three-axis accelerometer, a pair of bone conduction audio transducers (106), and a hardware processor (110). The hardware processor (110) computes dense disparity maps from stereo image pairs and converts the dense disparity maps to metric depth maps. The hardware processor (110) fuses the metric depth maps with inertial measurements through visual-inertial odometry to estimate six-degree-of-freedom pose of the system (100). The hardware processor (110) constructs a three-dimensional occupancy grid representation of an environment, identifies a plurality of objects within the three-dimensional occupancy grid representation, and generates binaural audio signals (114) positioning virtual sound sources corresponding to the plurality of objects using head-related transfer functions for delivery through the pair of bone conduction audio transducers (106) to achieve spatial audio feedback."
