How users interact with a 3D geo-browser under time pressure

Abstract

Interactive 3D geo-browsers, also known as globe viewers, are popular, because they are easy and fun to use. However, it is still an open question whether highly interactive, 3D geographic data browsing, and visualization displays support effective and efficient spatio-temporal decision making. Moreover, little is known about the role of time constraints for spatio-temporal decision-making in an interactive, 3D context. In this article, we present an empirical approach to assess the effect of decision-time constraints on the quality of spatio-temporal decision-making when using 3D geo-browsers, such as GoogleEarth, in 3D task contexts of varying complexity. Our experimental results suggest that while, overall, people interact more with interactive geo-browsers when not under time pressure, this does not mean that they are also more accurate or more confident in their decisions when solving typical 3D cartometric tasks. Surprisingly, we also find that 2D interaction capabilities (i.e., zooming and panning) are more frequently used for 3D tasks than 3D interaction tools (i.e., rotating and tilting), regardless of time pressure. Finally, we find that background and training of tested users do not seem to influence 3D task performance. In summary, our study does not provide any evidence for the added value of using interactive 3D globe viewers when needing to solve 3D cartometric tasks with or without time pressure.

When the display matters: A multifaceted perspective on 3D geovisualizations

“…Our results would refer specifically to altitude identification tasks in analogical interactive geovisualizations with particular focus on human perception issues. Although interactive 3D geovisualizations were previously explored by Wilkening and Fabrikant [9] or Bleisch, Dykes and Nebiker [26], in the majority of studies on this topic were used only static stimuli [7,15,17,29,30]. In our study, we present a comparison of different types of 3D geovisualizations in non-interactive and interactive tasks.…”

“…With the growing use of 3D technologies in many areas such as, geology, geomorphology, hydrology, oceanography, meteorology, teaching geography, virtual tourism, documentation and preservation of cultural heritage, urban and transport planning, noise mapping, 3D cadastre [1][2][3][4][5][6][7][8][9][10][11][12] and others, the usability of 3D visualizations is increasingly discussed. The importance of 3D visualization increases also in other fields such as crisis management and air traffic control (ATC), which represent geoscientific areas highly motivated to secure user-friendly ergonomics [13,14].…”

Evaluation in the Crowd. Crowdsourcing and Human-Centered Experiments

“…But clearly, the actual choice of a particular quantitative measure also includes a subjective component and is dependent on the expertise of the experimenter. Furthermore, sometimes difficulties arise, for instance, if the "correct response" cannot sufficiently be specified [27,103].…”

Combining user logging with eye tracking for interactive and dynamic applications

“…The next section details how to transform the screen coordinates to geographic coordinates in the cases of a panning and a zooming operation. These two interaction types are considered because they are most often used (Harrower & Sheesley, 2005;Wilkening & Fabrikant, 2013) Calculating geographic coordinates…”
