DTLens: Multi-user Spatial Data Exploration on Tabletops

UIST 2005

Supporting groups of individuals exploring large maps and design diagrams on interactive tabletops is still an open research problem. Today's geospatial, mechanical engineering and CAD design applications are mostly single-user, keyboard and mouse-based desktop applications. In this paper, we present the design of and experience with DTLens, a new zoom-in-context, multi-user, two-handed, multi-lens interaction technique that enables group exploration of spatial data with multiple individual lenses on the same direct-touch interactive tabletop. DTLens provides a set of consistent interactions on lens operations, thus minimizes tool switching by users during spatial data exploration.

Toolglass & Magic Lenses: The See-Through Interface

In current interfaces, users select objects, apply operations and change viewing parameters in distinct in distinct steps that require switching attention among several screen areas. Our See-Though Interface system addres this problem by locating tools on a transparent sheet that can be moved over applications with one hand using a trackball, while the other hand controls a mouse cursor.The user clicks through a tool onto application objects, simultaneously selecting an operation and an operand. Tools may include graphical filters, caled Magic Lens filters, that display a customized view of application objects

Gesture Registration, Relaxation, and Reuse for Multi-Point

Freehand gestural interaction with direct-touch computation surfaces has been the focus of significant research activity recently. While many interesting gestural interaction technique have been proposed, their design has been mostly ad-hoc and has not been presented within a constructive design framework. In this paper, we develop and articulate a set of design principles for constructing -- in a systematic and extensible manner -- multi-hand gestures on touch surfaces that can sense multiple points and shapes, and can also accommodate conventional point-based input. To illustrate the generality of these design principles, a set of bimanual continuous gestures that embody these principles are developed and explored within a prototype tabletop publishing application. We carried out a user evaluation to assess the usability of these gestures and use the results and observations to suggest future design guidelines.

We have to admit that the site is a tad old and ready for a refresh, but it is fun to interact with an old friend in a new way…
