Bridging the Gap with On-Device Intelligence

The VisionAId application redefines smartphone utility by integrating six on-device deep learning models, including metric monocular depth estimation, instance segmentation, visual and facial embeddings, face detection, and a custom banknote detector, all running efficiently via ONNX Runtime. This approach ensures real-time performance without constant cloud connectivity, a critical factor for accessibility. For enhanced scene understanding and object labeling, an optional cloud-based Google Gemini Flash model can be leveraged.

Personalized Assistance Through Few-Shot Learning

A core innovation is VisionAId's few-shot pipeline for personal object recognition. Users can train the system to identify specific items by providing a few images from different angles. Subsequently, the application can locate these personalized objects within the environment, guiding the user with augmented-reality markers, spatial audio cues, and distance-proportional haptic feedback. This multimodal feedback system, incorporating Romanian speech synthesis and voice commands, significantly boosts user independence.

Performance Gains and Precision in Real-World Scenarios

On a Samsung Galaxy S21 Ultra, INT8 quantization dramatically reduced depth estimation latency from approximately 1200 ms to 491 ms. The custom banknote detector achieved a remarkable mAP@50 of 0.986, demonstrating high accuracy. Furthermore, metric depth estimation was calibrated to an error of less than 1 cm within a 3-meter range. The strategic integration of on-device models, with optional support from powerful tools like Google Gemini Flash, showcases a robust architecture for practical assistive technology.
