Vision

A eye gaze tracking library based on computer vision and neural network for NeuralAction.

This repository is part of project NeuralAction.

Current gaze tracking model's mean error is 3.2 cm in 50 cm far without any calibration.

With calibration, mean error is ~1.8 cm.

Demo

  • Gaze tracking with calibrations

TODO
