Is past research on desktop-sized displays still relavent?
Advantages:
The size of the data-set is the primary reason users want to move off of a desktop
Virtual navigation imposed by a desktop interface can be disorienting, and the overhead of constantly
navigating the data set, e.g. with pan-and-zoom, can distract users and increase their cognitive load.
Results suggest that large displays facilitate tasks with multiple windows and rich information
because they offer a more immersive experience, with enhanced peripheral awareness
Larger displays promote physical navigation and improve user performance for search, navigation
and pattern-finding tasks
Even so, physical locomotion is more time-consuming and tiring than virtual navigation, and
manipulating data with well-known devices and widgets may be more efficient
Variables
Reasons for choosing the variables
Exp 1:
Three hypothesis:
Wall performs better than Desktop for smaller labels
Wall performs better than Desktop for harder tasks
Desktop performs better than Wall for larger labels and simpler tasks
Exp 2:
Analysis
[2x3x2] within-participants design with three factors: (display, labelsize, and difficulty)
Results:
For large labels, Desktop is faster than Wall for both Easy and Hard difficulty
For Medium labels there is no significant difference for Easy, but Wall is faster than Desktop for Hard
For Small labels, Wall is faster than Desktop for both Easy and Hard
