“…Participants were informed about this choice. To minimize possible influences due to the presence of bezels [4,11], objects were drawn fully within a wall tile on a black background. For Length, objects were oriented horizontally.…”

Fig. 1. Two viewers analyzing data visualizations from different viewpoints in front of a large high-resolution wall display (a). A participant conducting a trial during our first experiment (b).Abstract-We present the results of two user studies on the perception of visual variables on tiled high-resolution wall-sized displays. We contribute an understanding of, and indicators predicting how, large variations in viewing distances and viewing angles affect the accurate perception of angles, areas, and lengths. Our work, thus, helps visualization researchers with design considerations on how to create effective visualizations for these spaces. The first study showed that perception accuracy was impacted most when viewers were close to the wall but differently for each variable (Angle, Area, Length). Our second study examined the effect of perception when participants could move freely compared to when they had a static viewpoint. We found that a far but static viewpoint was as accurate but less time consuming than one that included free motion. Based on our findings, we recommend encouraging viewers to stand further back from the display when conducting perception estimation tasks. If tasks need to be conducted close to the wall display, important information should be placed directly in front of the viewer or above, and viewers should be provided with an estimation of the distortion effects predicted by our work-or encouraged to physically navigate the wall in specific ways to reduce judgement error.

“…Similarly the presence of interior bezels, may influence user behaviour on and around large public displays. For example, while research suggests that bezels have little impact on visual search performance [3,18], they may impact where users stand or choose to place content [4].…”

We explore how users approach and define personal space on large, public displays. Our results show that users of public displays use one of two strategies for visual search tasks: minimizers create a small window and work up close to the display, and maximizers expand content to its full resolution and work at a distance. We show that these interaction styles match predicted 'personal' and 'subtle' interaction zones, characterize typical width and height requirements for these interactions, and show that these requirements are independent of the onscreen content's dimensions. Finally, we suggest practical guidelines for defining workspaces during personal and subtle interaction on large, public displays.

“…The Stallion display at the University of Texas 4 is also constructed using 30-inch displays, with a resolution of 307 million pixels. NASA 5 have a Powerwall constructed of 128 20-inch panels, with a total resolution of 245 million pixels.…”

“…A flaw in this design is a set of unavoidable horizontal and vertical bezels between each of the monitors. While this does not hinder target selection [5], users generally prefer not to work across bezels where possible [14], and visual search errors are lower when data points do not cross bezels [5]. Therefore, a common method of interacting with multi-window environments on large displays is to house each window inside its own monitor.…”

High-resolution, wall-size displays often rely on bespoke software for performing interactive data visualisation, leading to interface designs with little or no consistency between displays. This makes adoption for novice users difficult when migrating from desktop environments. However, desktop interface techniques (such as task-and menu-bars) do not scale well and so cannot be relied on to drive the design of large display interfaces. In this paper we present HiReD, a multiwindow environment for cluster-driven displays. As well as describing the technical details of the system, we also describe a suite of low-precision interface techniques that aim to provide a familiar desktop environment to the user while Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.

We hope that these techniques, as well as the implementation of HiReD itself, can encourage good practice in the design and development of future interfaces for high-resolution, wall-size displays.
