SMARTGUIDE: Revolutionizing the Depth and Dependability of Vision-Impaired Navigation
Bibliographic record
Abstract
Globally, over 2.2 billion people face vision impairment, necessitating innovative solutions for safe, independent navigation. Traditional aids like canes, guide dogs, and GPS offer basic support but lack the sophistication to provide contextual understanding, precise navigation, or real-time hazard alerts. This project presents SmartGuide, a mobile app designed to enhance the independence of visually impaired users through AI-driven features. SmartGuide offers three main functions: (1) Smart Vision, using the GPT-4 Vision API to deliver spoken feedback about surroundings; (2) Navigation, combining QR code detection via YOLO with ZoeDepth for depth estimation, guiding users to destinations through the shortest path calculated by Dijkstra's algorithm; and (3) Obstacle Detection and Alerts, where YOLO identifies obstacles, and ZoeDepth estimates their distance to inform users of potential hazards. By adapting its responses based on user feedback, SmartGuide provides personalized, reliable guidance that empowers visually impaired individuals to navigate with confidence and safety, advancing the field of accessible technology.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
