               p Our add-ons give your AR/VR Headset eye tracking super-powers. Eye videos are transferred to your host via USB 2.0. 
               p The hardware is easily attached and removed. Eye cameras can run up to 120hz and have a latency of 5.7ms. Fast enough for interaction applications and detection of saccades and quick fixations.

              p Our goal is to work with and support a community of researchers and developers in creating reusable open source software for eye tracking in HMDs. 
              p Many researchers and developers have already thought of, or implemented eye tracking software HMDs. Instead of continuing to reinvent the wheel, we have formed a community with the goal of sharing knowledge and tools.
              p Fork the hmd-eyes code on  #[a(href="https://github.com/pupil-labs/hmd-eyes" rel="noopener") Github]. Chat with the hmd-eyes community on #[a(href="https://gitter.im/pupil-labs/hmd-eyes" rel="noopener") Gitter].
