The space-time cube represents a particular area or events over space and time. The base of the cube shows the geographical space, while time is presented on the vertical axis.
This visualization shows spatial growth of the Royal Castle in Warsaw, Poland. In the cube I placed historical buildings surrounding the castle from 1330 – 2015. Users can move the timeline, click on the buildings and get information about them from the pop-up box.
I interviewed 21 users and asked them to play around with the cube to answer four questions about the history of the castle. With the eye-tracker I registered the gaze concentrations (shown as circles) and gaze movements (lines between circles).
Participants had different strategies to answer the questions:
• some users were looking at the cube from the top to the bottom (#1),
• another were also reading the information in the pop-up boxes (#2).
• some users kept looking in one place (#3),
• while another were quickly changing their object of interest (#4),
• few users stayed with the default view of the cube (#5),
• some changed their point of view and location in time (#6).
Based on those insights I created a set of rules for the use of the spacetime cube in representing historical landscape.
