Eye movement as an indicator of users'involvement with embodied interfaces at the low level
Chunling Ma, Helmut Prendinger, Mitsuru Ishizuka · 2005
In this paper, we motivate an approach to evaluating the utility of animated interface agents that is based on human eye movements rather than questionnaires. An eye tracker is employed to obtain quantitative evidence of a user’s focus of attention. The salient feature of our evaluation strategy is that it allows us to measure important properties of the user’s interaction experience on a moment-by-moment basis. We describe an empirical study in which we compare attending behavior of participants watching the presentation of an apartment by three types of media: an animated agent, a text box, and speech only. Users ’ eye movements may also shed light on their involvement in following a presentation. 1
