Summary
This paper investigated the effects of visual separation in the context of Mobile Multi-Display Environments (MMDEs) and contrasts these with fixed MDE results, while highlighting the design factors for Mobile MDEs. The study focuses on a novel eye-tracking methodology for measuring switches in visual context between displays and identifies that MMDEs offer increased design flexibility over traditional MDEs in terms of visual separation.
Opinion
A key question in designing collaborative applications for any platform is whether to use single or multiple displays. This has become an important consideration as the emergence of projector phones – cell phones with built-in projectors – potentially enable new forms of collaboration around mobile devices. On the other hand applications of eye-tracking in the research of collaborative tasks have been minimal to date. The visual-separation system setup presented in this paper can be considered specific to the field of the collaborative programming, and could be a viable starting point for future designs. Nevertheless, I believe the main challenges of the collaborative visual attention analysis are related to inconsistencies in the data analysis.
