Abstract. This project aims to overcome the access barriers to virtual worlds
for motor- and speech-impaired users by building a gaze-controlled interface
for Second Life that will enable them to interact with the virtual world by just
moving their eyes. We have conducted a study to assess (1) the facilitation of
gaze-controlled text input using word prediction technique to speed up chat-
style text input in virtual worlds, (2) the influence of screen layout on the
efficiency of text input, (3) the effect of the maximum number of suggested
