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. With the Beam SDK license you can distribute the eye and head tracking enabled apps that you have built. For the end-users to be able to use these functionalities that are integrated within your app they need to :

  • have the iOS Eyeware Beam app installed and running;
  • they need to have an active subscription for the iOS Eyeware Beam app
Is there a free trial before committing to a subscription?

Almost. You can get most of the experience for free. Just go ahead and download the Eyeware Beam app from the App store (free while in Beta), and you will get a good feeling on the overall eye and head tracking experience. You can also download the SDK and inspect what’s in the package, check the documentation and study the samples.

What’s missing is that you won’t be able to access the eye and head tracking data in real-time, unless you have an active subscription. We promise that the code samples work, nevertheless!

Are you offering support?

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

Are there currently any apps built by the community using the Beam API?

Not yet, but we promise to share with you a list of the apps we find out about. If you’ve built an app with the Beam SDK and want to promote it within the community, please let us know about it in the #Beam-API-integration channel on our Discord server and we will do our best to help out.

Why should I use Eyeware Beam as a head and eye tracking app instead of buying a classic eye and head tracking hardware device?

With Eyeware Beam you can reach a wider audience. It’s more likely that the end-user of your app has a TrueDepth enabled iOS device (eg. iPhone 12) than a single-purpose eye tracker device at home. 

Both the head and eye tracking run entirely on the iOS device. This means that the end-user won’t have to worry about wasting CPU/GPU resources. This makes it ideal for gaming or streaming experiences, amongst others.

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

Definitely. Let us know if you publish a study with it. We would love to promote it.

(The only restriction is that you are not allowed to collect data with the purposes of reverse engineering or replicating Beam (e.g. training an AI). That would be a breach of license.)


What are the minimum hardware requirements (iPhone X, Windows, etc.)?

You need to have the following:

  • An iPhone or an iPad with Face ID – check the list of devices here
  • A Windows PC or laptop (Windows 10). The PC app is lightweight, but you do need around 1GB of space in your hard drive.
Are you building an app for Android & Mac, too?

It is part of our roadmap, but we don’t have a specific date at which we will deliver this.  Please send us an email to [email protected] with your ideal setup and what you want to use Beam for.

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.

Do you offer discounts for multiple licenses?

If you are interested in buying multiple licenses please contact our sales team at [email protected]

Are end-user licenses transferable?

Unfortunately, this can’t be achieved easily through the App Store. If you have special requests, please contact our sales team at [email protected]

Can I get eye tracking data for interaction with the mobile device itself?

No. Beam was designed to transform your iOS device into an eye and head tracking peripheral for a Windows PC. If you have special requests, contact our sales team at [email protected]
