Abstract
This UCF invention introduces wearable eyewear that integrates two LiDAR channels and an IR
thermal sensor to deliver real-time audible guidance for blind and low-vision
users. The system scans forward and downward fields of view, computes distance
to obstacles, and modifies audio cues when thermal power exceeds
thresholds—signaling people/animals versus inert objects—via on-device or
wireless audio. This extends perception beyond ground contact to reduce
collisions and improve mobility confidence.
Technical Details: The eyewear integrates two compact LiDAR modules and an IR thermal sensor into a polycarbonate frame, enabling simultaneous forward and downward scanning for obstacle detection. The forward LiDAR projects a beam nearly parallel to the walking surface to detect mid-height obstacles, while the downward LiDAR scans to identify ground-level hazards; both measure distance using pulsed time-of-flight returns processed by onboard circuitry. Thermal emissions captured by the IR sensor are compared against a threshold to indicate live objects, prompting modified auditory cues. A processor fuses LiDAR distance data and thermal readings, converting them into tonal audio patterns where pitch increases as proximity decreases and additional modulation signals the presence of heat-emitting obstacles. Audio outputs are delivered through an integrated speaker or wirelessly to hearing aids or earbuds
Benefit
3D awareness: Detects overhangs, signs, branches and floor obstacles—beyond the reach of canes alone.Prioritization: Thermal cues distinguish people/animals from walls/furniture to guide safer path choices.Hands-free, familiar form factor: Eyewear reduces stigma and preserves hand use.Scalable build: Uses off-the-shelf compact LiDAR/IR; minimal moving parts via scanned beams.Market Application
Assistive mobility: Everyday navigation for blind/low-vision users at home, work, transit, and outdoors.Rehab/O&M training: Complement to cane/guide dog programs for orientation & mobility.Elder safety: Fall-risk and hazard awareness in senior-living environments.Consumer electronics: products for the visually impaired community.
