displays can result in better performance than panning and zooming on smaller displaysRobert Ball and Chris North. Effects of tiled high-resolution display on basic visualization and navigation tasks.
Motivation: ViewportIs bigger (viewport) better? Is there a display that is too big?
More detailed data & more context at once
(3072 x 10,240)
Physical navigation using eye, head, and body movement
Motivation: CurvatureWhat happens if we curve the display?
Reduce time physically navigating
Change physical navigation to less strenuous turning rather than walking
Motivation: Curvature
All pixels are resolvable using only head and eye movements
(2.75 times more resolvable pixels on our 24 monitor display)
