Hi @ommr and thanks for your query. A number of clients have in the past managed to operate with ARM processors using the Stream Engine under Linux for which you can download the alpha @ https://developer.tobii.com/consumer-eye-trackers/stream-engine/getting-started/
Please not the software is still in early development and little support is provided, but should you wish to take a look, we would be more than happy to hear about your experiences! Kindly let us know if we can be of any further assistance.
