Abstract
As reported by a recent survey, over half of large display purchases are conducted for productivity purposes, while the remainder are purchased for a variety of purposes such as gaming and advertising. These large displays have advanced visibility, scalability, and accessibility
characteristics and thus benefit perceived usability. However, usability issues such as the difficulties in precisely accessing distal information on large displays while on the move are still of concern. Therefore, in this paper, we investigate the influence of moving distance
on perceived usability in interactions with large displays. Comparative study results show inconsistent perceived usability throughout a range of distances, which differs from standard usability conventions. Moreover, the results show a correlation between distance and perceived
usability in that, as the distance from commonly visited ranges increases, the perceived usability level decreases, and vice versa. The study demonstrates that distance is an effective interaction modality in large-display interactions, although it has weaknesses such as limited
input channels.
