Controlling file systems with gaze

In recent years, free and open-source gaze tracking systems have become available, making the traditionally expensive technology affordable. Such systems have a range of applications, from research in fields as diverse as psychology, neuroscience and advertisement, to the development of a new interaction modality to reduce the physical strain in mundane activities, to providing control of a computer to severely disabled people. Despite that, gaze tracking technology remains largely unknown to the general public. This thesis discusses some reasons for the lack of popularity of gaze tracking systems, and proposes that developing a fully gaze-controllable operating system and developing gaze-added interfaces are two good paths to spread the technology. This discussion is enriched by a review of techniques developed to overcome the shortcomings of gaze tracking systems. In order to make a small contribution to the goal of developing a gaze-controlled operating system, this thesis provides four different file manager designs, which are evaluated in an experiment with the help of twelve participants. The results indicate that a Dasher-like interface may be a poor choice for a file management environment, while a gesture-activated may be a more popular choice. Asiasanat:gaze tracking, file managin
