Precision Pointing for Ultra-High-Resolution Wall Displays

Abstract : Ultra-high-resolution wall displays have proven useful for displaying large quantities of information, but lack appropriate interaction techniques to manipulate the data efficiently. We explore the limits of existing modeless remote pointing techniques, originally designed for lower resolution displays, and show that they do not support high-precision pointing on such walls. We then consider techniques that combine a coarse positioning mode to approach the target's area with a precise pointing mode for acquiring the target. We compare both new and existing techniques through a controlled experiment, and find that techniques combining ray casting with relative positioning or angular movements enable the selection of targets as small as 4 millimeters while standing 2 meters away from the display.
