In this work, we aim to tackle this issue by investigating a system concept that allows for the deployment of remote eye-trackers for mobile devices. We describe a toolkit that supports eye-tracking in mobile apps based on a simple phone, PC, and remote eye tracker setup. We evaluate our approach through a technical evaluation of accuracy and precision in various user contexts important for mobility (sitting, standing, walking, lying). Our results show that eye-trackers can be easily used with high accuracy, and how it is impacted through body posture and motions of the user. Our work paves the way for enabling easy-to-use eye-tracking studies on mobile devices.}, note = {}, institution = {Universität der Bundeswehr München, Fakultät für Informatik, INF 5 - Institut für Anwendungssicherheit, Professur: Alt, Florian}, }
