“…Hancock et al [13] improve awareness in menu placement for tabletop display by designing menus that detects user handedness. Brandl et al [20] also designed occlusion-aware menus that are positioned around the table so that they are not occluded.…”

Abstract. 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 is different depending on the visual display, suggesting a tradeoff between management strength and visual space deformation.

“…As a result, pie menus naturally emerge as a possible implementation that maximizes the area the user can select from [9] (e.g., compared to say a linear menu). However, due to limitations of the wrist (DG4) and past research on potential hand occlusion with pie menus on touch surfaces [8,35], we designed our context menu based on the menu used in the study, which was implemented as a partial pie consisting of 3 rings × 3 wedges allowing for 9 possible items to be displayed at a time.…”

Context menus, most commonly the right click menu, are a traditional method of interaction when using a keyboard and mouse. Context menus make a subset of commands in the application quickly available to the user. However, on tabletop touchscreen computers, context menus have all but disappeared. In this paper, we investigate how to design context menus for efficient unimanual multi-touch use. We investigate the limitations of the arm, wrist, and fingers and how it relates to human performance of multi-targets selection tasks on multi-touch surface. We show that selecting targets with multiple fingers simultaneously improves the performance of target selection compared to traditional single finger selection, but also increases errors. Informed by these results, we present our own context menu design for horizontal tabletop surfaces.

“…Interaction techniques have been designed with occlusion in mind [2,15,22], but these have no awareness of what is actually being occluded by a particular user. Hancock and Booth [10] and Brandl et al [5] go a step further by demonstrating menu designs which automatically compensate for occlusion based on handedness and which menu positions are typically occluded by most users.…”

We define occlusion-aware interfaces as interaction techniques which know what area of the display is currently occluded, and use this knowledge to counteract potential problems and/or utilize the hidden area. As a case study, we describe the Occlusion-Aware Viewer, which identifies important regions hidden beneath the hand and displays them in a non-occluded area using a bubble-like callout. To determine what is important, we use an application agnostic image processing layer. For the occluded area, we use a user configurable, real-time version of Vogel et al. 's [21] geometric model. In an evaluation with a simultaneous monitoring task, we find the technique can successfully mitigate the effects of occlusion, although issues with ambiguity and stability suggest further refinements. Finally, we present designs for three other occlusion-aware techniques for pop-ups, dragging, and a hidden widget.
