FAQ

What is an eye and head tracking enabled PC application?

An eye and head tracking enabled PC application is an app in which the software can react to head movements, eye movements, or more specifically, where the user is looking at any given time. This includes applications in which the content changes according to the gaze, a vtubing avatar is controlled with your natural head and eye movements, a window can be selected with your eyes, an NPC (non-playing character) reacts when you are looking at them, or even applications that are used to research user experience. The possibilities are endless.

Can I distribute my eye and head tracking enabled application to my end users?

Yes. You may distribute the eye and head tracking enabled app(s) that you have built with the Eyeware Beam SDK license. End-users must have the iOS Eyeware Beam app installed and running with an active subscription to use these functionalities that are integrated within your app.

Do you offer support?

Yes. Our support team is here for you, from Monday to Friday, between 9 am – 5 pm (Central Eastern European Time). We offer timely replies so that you can focus on building your product.

I am interested in conducting eye-tracking studies. Can I record and analyze data with the Beam SDK for that purpose?

Yes. Please let us know if you publish a study with it. We would love to promote it. Please keep in mind that you may not collect data to reverse engineer or replicate Eyeware Beam (e.g. training an AI). That is a breach of license.

What data is available through the API?

The most up-to-date list can be found on the API documentation page, in particular, what is accessible through the `TrackerClient`.

Can I see an example of the API data output?

Yes, please check out the Getting Started section of the documentation, subsection Output.
