C# SDK for the EyeTribe Dev Kit

Introduction

This is the C# library implementation for the EyeTribe Dev Kit. This reference implementation provides a simple C# interface for communicating with the EyeTribe Server through our open TET API. This allows developers to easily get started and focus their energy on creating innovative and immersive apps using our eye tracking technology.

This version is to be considered beta. Feedback and bug fix submissions are welcome.

Please visit our developer website for documentation and tutorials. Please use our public forum for questions and support.

Dependencies

The implementation is .NET 3.5 compliant for backwards compatibility and Unity support. The library uses Json.NET for JSON parsing.

Build

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

Note that building for .Net 3.5 compliance may require the installation of .Net Framwork 3.5 SP1

Tutorials

A simple guide to using this C# SDK is found in the tutorials section of our developer website. More tutorials will be provided in the near future.

Samples

Open source samples for windows are available through GitHub. These samples shows how to calibrate the EyeTribe Server and give examples of how unique user experiences can be created using eye tracking.

Documentation

Find documentation of this library at EyeTribe C# Doc.

API Reference

The complete API specification used by the C# SDK to communicate with the server is available on our developer website.
