GLANCE: Gaze-Led Attention Network for Compressed Edge-inference

Real-time object detection in AR/VR systems faces critical computational constraints, requiring sub-10,ms latency within tight power budgets. Inspired by biological foveal vision, we propose a two-stage pipeline that combines differentiable weightless neural networks for ultra-efficient gaze estimation with attention-guided region-of-interest object detection. Our approach eliminates arithmetic-intensive operations by performing gaze tracking through memory lookups rather than multiply-accumulate computations, achieving an angular error of 8.32circ with only 393 MACs and 2.2 KiB of memory per frame. Gaze predictions guide selective object detection on attended regions, reducing computational burden by 40-50% and energy consumption by 65%. Deployed on the Arduino Nano 33 BLE, our system achieves 48.1% mAP on COCO (51.8% on attended objects) while maintaining sub-10,ms latency, meeting stringent AR/VR requirements by improving the communication time by × 177. Compared to the global YOLOv12n baseline, which achieves 39.2%, 63.4%, and 83.1% accuracy for small, MEDium, and LARGE objects, respectively, the ROI-based method yields 51.3%, 72.1%, and 88.1% under the same settings. This work shows that memory-centric architectures with explicit attention modeling offer better efficiency and accuracy for resource-constrained wearable platforms than uniform processing.
