Abstract
A Multiscale Interaction Technique for Large, High-Resolution Displays

Sarah M. Peck

Abstract

The decreasing price of displays has enabled exploration of ever-larger high-resolution displays. Previous research has shown that as the display grows larger, users prefer to physically navigate, which has proven benefits. However, increasing the display size so radically creates a new difficulty in interaction. The paradigm has changed from sitting at a desktop computer to taking users’ physical navigation into account and designing more mobile interactions.

Currently, when users move, they change the scale at which they are viewing information without changing the interaction scale. This is a problem because tasks change at different levels of visual scale. Mulitscale interaction aims to exploit users’ movement by linking it to interaction, changing the interaction scale depending on users’ distance from the display.

This work accomplishes three things: first, we define the design space of multiscale interaction; secondly, through a case study, we explore the design issues for a specific area of the design space; lastly, we evaluate one application through a user study that compares it to two other interaction types. We wanted to know, do users in fact benefit from the linkage of physical navigation with interaction?

Results show a trend of a natural link between user distance and interaction scale, even with the other techniques that did not enforce this link. In addition, multiscale interaction benefits from the link by having more consistent performance. They also show that while participants using multiscale interaction tend to move more, they benefit from this additional movement, unlike with the other interaction types.
