A month ago, Overwolf, SteelSeries and Tobii announced the Sentry development Challenge 2014. The challenge is currently in progress so it is too late to sign up. However, you can still use the Overwolf SDK if you want to use your Tobii EyeX compatible eye tracker to build game overlay apps with Tobii EyeX functionality.

The JavaScript API available in Overwolf offers a small subset of the Tobii EyeX Engine API , but there is still a lot of awesome things you can do. On the Overwolf developer section, you can read more about how to get started or the available API functionality.

If you want to discuss the Tobii EyeX API available in Overwolf, you are welcome to use the forums. You may also contact [email protected] for more support related issues regarding the Overwolf integration.
