With similar visual angles, larger displays improve spatial performance

Abstract

Large wall-sized displays are becoming prevalent. Although researchers have articulated qualitative benefits of group work on large displays, little work has been done to quantify the benefits for individual users. We ran two studies comparing the performance of users working on a large projected wall display to that of users working on a standard desktop monitor. In these studies, we held the visual angle constant by adjusting the viewing distance to each of the displays. Results from the first study indicate that although there was no significant difference in performance on a reading comprehension task, users performed about 26% better on a spatial orientation task done on the large display. Results from the second study suggest that the large display affords a greater sense of presence, allowing users to treat the spatial task as an egocentric rather than an exocentric rotation. We discuss future work to extend our findings and formulate design principles for computer interfaces and physical workspaces.

Effects of tiled high-resolution display on basic visualization and navigation tasks

“…[2] [4] show advantages of higher resolutions for standard highlevel desktop applications tasks, using up to 3 tiled screens. Studies such as [5] show advantages of large size, but low resolution. [1] shows visualization advantages of a mixed density display that implements focus+context by combining a small and large size display, both at low resolution.…”

Impact of large displays on virtual reality task performance

“…Many applications provide cognitive aids to reduce the gap between users'abilities and those require by devices uses and to increase users' efficiency. In VR, large displays can be considered as a cognitive aids for some kinds of tasks [Patrick et al 2000], [Tan et al 2003]. Many questions about this aid have not yet been answered: do all users take advantage of large displays?…”

“…Their emergence in VR was motivated by the need for collaborative works, visualization of multilevel information and dense scenes. Two main studies, Patrick [Patrick et al 2000] and Tan [Tan et al 2003], show the positive influence of large displays on performances.…”

“…Another research is the comparative study of Tan [Tan et al 2003] between desktop monitors and large displays. The user's DFOV is constant.…”

Multiuser-centered resource scheduling for collaborative display wall environments

“…Large-scale, highresolution display walls are used in scientific disciplines because they are an effective way to provide both context and details when visualizing high-resolution data. Furthermore the expansive size and exquisite resolution of the display has been conclusively shown to positively impact the scientific discovery process by allowing researchers to juxtapose multiple high-resolution visualizations simultaneously [1][2][3][4][5][6][7][8]. A common way to build large-scale display walls is to tile multiple individual displays and connect them to a cluster of computers.…”
