“How wide should paragraphs be formatted for optimal reader retention and ease of reading? While everyone is familiar with the narrow, multi-column formatting in newspapers and magazines, research on the issue is not consistent. Early work using printed media favored narrow formatting, while more recent work using computer monitors has favored wider formatting. In this paper, we approach this issue by using eye tracking analysis of users reading material on instructional web pages. In our experimental system, subjects read the material using an instrumented browser that records all HTML content and browser actions, and their eye gaze is recorded using a nonobtrusive, "remote" eye tracker. Comparing the wide and narrow formatting conditions, our analysis shows that for narrow formatting, subjects (a) read slightly faster, (b) have fewer regressions, (c) retain more information in a post-test of the material, but (d) tend to abandon the ends of longer paragraphs.”

“We developed and studied an experimental system, RealTourist, which lets a user to plan a conference trip with the help of a remote tourist consultant who could view the tourist's eye-gaze superimposed onto a shared map. Data collected from the experiment were analyzed in conjunction with literature review on speech and eye-gaze patterns. This inspective, exploratory research identified various functions of gaze-overlay on shared spatial material including: accurate and direct display of partner's eye-gaze, implicit deictic referencing, interest detection, common focus and topic switching, increased redundancy and ambiguity reduction, and an increase of assurance, confidence, and understanding. This study serves two purposes. The first is to identify patterns that can serve as a basis for designing multimodal human-computer dialogue systems with eye-gaze locus as a contributing channel. The second is to investigate how computer-mediated communication can be supported by the display of the partner's eye-gaze.”
