SeeSo Eye Tracking Demo is an Android app developed by VisualCamp. This free app lets you try a simple and easy eye-tracking demo from your Android device. The app's main feature is the real-time gaze path that follows where you are looking at. The app also provides a quick 5-point calibration process that you can load later without having to redo the process. It's important to note that only 'portrait mode' is supported for this demo.

Overall, the SeeSo Eye Tracking Demo is a useful app that provides accurate eye-tracking data. The app is perfect for those who want to experience eye-tracking technology without having to spend money. If you like this demo, you can download the SeeSo SDK and develop your own eye-tracking app. The SeeSo SDK is available on their website and includes helpful documentation to get you started.

It's worth mentioning that SeeSo provides business inquiries and development inquiries through their email addresses. However, these are not necessary for using the SeeSo Eye Tracking Demo.
