MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202641001531 A) filed by Meenakshi Academy Of Higher Education and Research, Chennai, Tamil Nadu, on Jan. 7, 2026, for 'system and method for touch-based audio-spatial mapping of surroundings for blind users.'
Inventor(s) include Dr. A. Josephine; and Dr. V. Sureka Varalakshmi.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a mobile-based assistive system and method for enabling blind and visually impaired users to explore and perceive their surrounding physical environment through touch gestures combined with real-time audio-spatial feedback. The system is implemented on a smartphone comprising a processor, a camera, a LIDAR sensor, a depth sensor, a touchscreen, and an audio output unit. Environmental data captured by the sensors is processed using embedded artificial intelligence and spatial rendering software to generate a three-dimensional spatial representation of detected objects. Finger gestures performed on the touchscreen are interpreted as exploration commands corresponding to directions and proximity within the environment. In response, the system generates spatialized audio cues conveying object identity, distance, and orientation. The system further supports gesture-based zooming, voice query interaction, indoor and outdoor environment adaptation, and dynamic updating of spatial information in response to moving objects. All processing is performed on-device, enabling offline operation with improved privacy and real-time performance."
