Eye gaze and speech for data entry: a comparison of different data entry methods

In this paper we present a multimodal interface that employs speech recognition and eye gaze tracking technology for use in data entry tasks. The aim of this work is to compare the usability of this multimodal system against other data entry methods (handwriting, mouse and keyboard and speech only) when carrying out the data entry task of filling a form. Discussions regarding the relationships between efficiency, effectiveness, ergonomic quality, hedonic quality, naturalness, familiarity and users preference are presented. The experimental results show that the majority of the users prefer using the proposed eye and speech system compared to the other form-filling methods even though such a method is neither the fastest nor the most accurate.
