Eye typing could provide motor disabled people a reliable method of communication given that the text entry speed of current interfaces can be increased to allow for fluent communication. There are two reasons for the relatively slow text entry: dwell time selection requires waiting a certain time, and single character entry limits the maximum entry speed. We adopted a typing interface based on hierarchical pie menus, pEYEwrite [Urbina and Huckauf 2007] and included bigram text entry with one single pie iteration. Therefore, we introduced three different bigram building strategies. Moreover, we combined dwell time selection with selection by borders, providing an alternative selection method and extra functionality. In a longitudinal study we compared participants performance during character-by-character text entry with bigram entry and with text entry with bigrams derived by word prediction. Data showed large advantages of the new entry methods over single character text entry in speed and accuracy. Participants preferred selecting by borders, which allowed them faster selections than the dwell time method.
