Test procedure
Online survey (SelectSurvey.NET)
Computer lab
5 Atlas GUI layouts varying in layout density and tool arrangement
5 typical use cases for atlases
4
Mouse click coordinates captured (max. 10 clicks per task)
Times captured (max. 20 seconds per task)
Overall rating of the five layouts (attractiveness, usability)

Tasks
1) Change theme: Switch from “Geology” to “Raw materials”
2) Find legend: Resolve the meaning of map colors and symbols in the map
3) Map query: Determine the name of the settlement and the underlying geological structure in the center of the map
4) Map info: Access additional media (e.g. text, images)
5) Spatial orientation: Find out where the displayed map region is located within Switzerland

Conclusions
Atlas GUIs with a large map panel and a slim interface are not preferred by Digital Natives
Digital Natives performed significantly better in Atlas GUIs with a medium tool density
Recommendations:
Functions/Tools should be grouped, not distributed
GUI elements should be tested for ambiguity
The use and effect of a tool should be easily recognizable
