We propose a patterns-based approach to evaluating data visualization: a set of general
and reusable solutions to commonly occurring problems in evaluating tools, techniques, and …

Multitouch surfaces are becoming prevalent, but most existing technologies are only
capable of detecting the user's actual points of contact on the surface and not the identity …

Pervasive interfaces can present relevant information anywhere in our environment, and
they are thus challenged by the non rectilinearity of the display surface (eg circular table) …

In this paper, we address the challenges of occlusion created by physical objects on
interactive tabletops. We contribute an integrated set of interaction techniques designed to …

Selecting and positioning objects in 3D space are fundamental tasks in 3D user interfaces.
We present two new techniques to improve 3D selection and positioning. We first augment …

When introducing interactive tabletops into the home and office, lack of space will often
mean that these devices play two roles: interactive display and a place for putting things …

We investigate how users managed physical and digital objects during the longitudinal field
deployment of a tabletop in a biology laboratory. Based on the analysis of 15 hours of video …

The screen of a tabletop computer is often occluded by physical objects such as coffee cups.
This makes it difficult to see the virtual elements under the physical objects (visibility) and …

Emerging research and growing use of mobile projectors reveal a need for better
understanding of how to design interaction with such devices. This paper examines key …

In a world of data, pervasively-displayed interfaces (also referred to as" displays
everywhere") will be essential to provide access to data anytime and anywhere. The vision …
