# OpenGaze: Open Source Toolkit for Camera-Based Gaze Estimation and Interaction
Appearance-based gaze estimation methods that only require an off-the-shelf camera have significantly improved and promise a wide range of new applications in gaze-based interaction and attentive user interfaces. However, these methods are not yet widely used in the human-computer interaction (HCI) community.
To democratize their use in HCI, we present OpenGaze, the first software toolkit that is specifically developed for gaze interface designers. OpenGaze is open source and aims to implement state-of-the-art methods for camera-based gaze estimation and interaction.
## Functionality
The toolkit is capable of performing the following gaze-related tasks:
* **Gaze Estimation**
Show estimated gaze on the screen given screen-camera relationship.

* **Gaze Visualization** Show gaze direction inital from the center of faces in the input image. [](https://youtu.be/8yMTvvr0rRU "Gaze visualization demo")
* **Personal Calibration** Perform personal calibration and remapped the gaze target on the screen. [](https://youtu.be/ntBv1wcNGAo "Gaze visualization demo")
