  • Start date: June, 2010

We evaluate unguided and guided visual search performance for a set of techniques that mitigate occlusion between physical and virtual objects on a tabletop display. The techniques are derived from a general model of hybrid physical/virtual occlusion, and take increasingly drastic measures to make the user aware of, identify, and access hidden objects—but with increasingly space-consuming and disruptive impact on the display. Performance results are markedly different depending on the structure of the display, suggesting a tradeoff between management strength and visual space deformation.
