C# samples for The Eye Tribe Tracker

Introduction

This is the C# samples repository for The Eye Tribe Tracker. The implementation provides examples of how to use eye gaze coordinates for simple UI interaction. Furthermore, it contains basic UI elements useful to give feedback to the user and run a calibration.

More samples will be added to the repository in the near future.

Please visit our developer website for more information.

TETControls

Provides example implementations of TrackBox and Calibration UI elements. These are employed in other samples.

Calibration

The calibration sample can be used to perform a user-based calibration on the system.

Scroll

The Scroll sample is a demonstration of how to employ natural scroll interaction while reading information-dense content (e.g., websites). Changing the information content is done with the mouse. A mouse-button down invokes a gaze-sensitive menu with selectable items and a mouse-up signals a selection to the application.

Dependencies

This sample uses the EyeTribe C# SDK.

Build

To build, open solution file in compliant Visual Studio version and build.
