MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202641096646 A) filed by Vellore Institute Of Technology on August 10, 2026, for Swing-Referenced Assistive Cane With Drop-Off Prediction And Acoustic Threat Localization.
Inventors include Charanya; and Arun Roshan E.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The present invention discloses a swing-motion-referenced intelligent assistive cane for visually impaired users, configured for multi-hazard detection and prioritized navigation assistance. The system integrates an inertial measurement unit (101), downward time-of-flight sensor (102), microphone array (103), hazard detection pillars (104, 105), and a hazard fusion pillar (106). The system utilizes cane swing, gait cadence, and tap events as a common kinematic reference to predict negative obstacles and compensate acoustic threat localization during cane movement. A haptic cue module (107) and optional voice guidance module (108) provide intuitive warnings based on time-to-hazard prioritization. A microSD logging module (109) stores synchronized sensor data and learning parameters. The invention operates through low- cost embedded hardware with on-device processing, eliminating dependence on cameras, smartphones, or cloud infrastructure while enabling reliable real-time mobility assistance in indoor and outdoor environments.
