In this article the complexity of the construct engagement and three theories on this topic are discussed. Csikszentmihalyi's theory of flow is taken as starting point for the measurement of engagement. The measurement of each of its eight aspects is discussed, including its pros and cons. Regrettably, no overarching computational model is available. This article ends with a concise discussion.

This report summarizes progress to date on an ongoing joint research project between the HIT Lab at the University of Washington and the Molecular Graphics Lab at The Scripps Research Institute (TSRI). The goals of this research are to develop and evaluate novel interface tools for teaching and conducting research in the field of molecular biology. These interface tools are integrated within TS...

Good holograms are bewitching. They command our eyes to their images, to search the marvelous realness of surfaces, textures, and minute detail for some aberration, some visual clue that will dissuade us from seeing as real what we know is not. Yet while they seem to assemble the very molecules of physical matter for us to ponder, they also present a conundrum: The objects they render appear fr...

Tangible interfaces allow physical control and representation of digital information. When designing such interfaces one needs to take into consideration the potential conflicts between the hardware of the artifact and the form of the user control. The design problem is a search for an appropriate fitness (or effortless coexistence) between these two aspects. This problem makes tangible interfa...

Mary Lou Maher is a design researcher with an interest in novel user interfaces to support designing and computer support for collaborative design; she is the Professor of Design Computing at the University of Sydney. Mi Jeong Kim is a design researcher with an interest in designers' cognition while using tangible user interfaces; she is a PhD student in theABSTRACT Most studies on tangible use...

3D puzzles provide valuable opportunities for both individuals and groups of people to explore, learn, and create in a natural way. In educational settings, learners using these tools can benefit from occasional intervention by a knowledgeable “guide on the side”. In our project, Tangible Interfaces for Collaborative Learning Environments (TICLE), we are exploring innovative ways of enabling a ...

This paper presents a new circular tangible interface where one or multiple users can collaborate and interact in real time by placing and moving passive wooden pucks on a transparent tabletop in order to create music. The design encourages physical intuition and visual feedback on the music being created. An arm with six optical sensors rotates beneath a transparent surface, triggering sounds ...

Tangible augmented reality interfaces offer a hands on approach for examining objects and exploring the associated information. We describe two tangible augmented reality interfaces that can expose the adaptation of information presented to users about objects in augmented reality environments.
