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

Ultimately
