成果简介	NOVELTY - The system has light detection and ranging (LiDAR) sensors integrated into a footwear to emit laser pulses for performing spatial mapping and obstacle detection. A UWBreceiver (106) interacts with UWBbeacons placed in indoor environments, and enables precise centimeter-level positioning through time-of-flight (ToF) measurements. A feedback unit (112) generates haptic and auditory feedback signals based on obstacle proximity and navigation guidance. A power source comprises a rechargeable lithium-ion battery to provide power to system components and optimize energy usage. The sensors are strategically positioned at front and sides of the footwear to maximize field of view and enhance obstacle detection accuracy. USE - Intelligent navigation footwear system for visually impaired users in enclosed spaces e.g. shopping malls, airports, and office buildings. Uses include but are not limited to a hybrid ultra-wideband (UWB) and a LiDAR-powered smart footwear system. ADVANTAGE - The advanced assistive system enhances navigation and situational awareness for visually impaired individuals. The LiDAR sensors are strategically positioned at the front and sides of the footwear to maximize field of view and enhance obstacle detection accuracy. The UWBreceiver is configured to continuously receive signals from multiple UWBbeacons, enables high-precision indoor navigation in global positioning system (GPS)-denied environments. The user is enabled to personalize feedback settings through a companion mobile application or onboard interface. The feedback unit includes haptic feedback modules, including embedded vibration motors that deliver haptic and auditory feedback signals based on obstacle proximity and navigation guidance and a power source comprising a rechargeable lithium-ion battery configured to provide power to system components and optimize energy usage. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of an intelligent navigation footwear system. 100Smart footwear system 106UWB receiver 108Microcontroller 110Rechargeable power source 112Feedback unit
