We are in the midst of an explosion of emerging human-computer interaction techniques that redefine our understanding of both computers and interaction. We propose the notion of <i>Reality-Based Interaction</i> (RBI) as a unifying concept that ties together a large subset of these emerging interaction styles. Based on this concept of RBI, we provide a(More)
In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users’ knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research(More)
This paper introduces a paradigm for describing and specifying tangible user interfaces (TUIs). The proposed Token and Constraints (TAC) paradigm captures the core components of TUIs while addressing many of the conceptual challenges unique to building these interfaces. The paradigm enables the description of a broad range of TUIs by providing a common set(More)
We are in the midst of an explosion of emerging human-computer interaction techniques that have redefined our understanding of both computers and interaction. We propose the notion of <i>Reality-Based Interaction</i> (RBI) as a unifying concept that ties together a large subset of these emerging interaction styles.

Tangible interaction shows promise to significantly enhance computer-mediated support for activities such as learning, problem solving, and design. However, tangible user interfaces are currently considered challenging to design and build. Designers and developers of these interfaces encounter several conceptual, methodological, and technical difficulties.(More)
We present G-nome Surfer 2.0, a tabletop interface for fostering inquiry-based learning of genomics. We conducted an experimental study with 48 participants that compared students' learning of genomic concepts using existing bioinformatics tools and using two alternative implementations of G-nome Surfer: a collaborative multi-mouse GUI and a tabletop(More)
In this paper we introduce the <i>Tangible Video Editor</i> (TVE), a multi-user, tangible interface for sequencing digital video. We present a new approach to tabletop interaction by using multiple handheld computers embedded in plastic tokens. Drawing from the rich physical experience of tradition film editing techniques we designed the TVE to engage(More)
Molecular and computational biologists develop new insights by gathering heterogeneous data from genomic databases and leveraging bioinformatics tools. Through a qualitative study with 17 participants, we found that molecular and computational biologists experience difficulties interpreting, comparing, annotating, sharing, and relating this vast amount of(More)
Multi-touch and tangible interfaces provide unique opportunities for enhancing learning and discovery with big data. However, existing interaction techniques have limitations when manipulating large data sets. Our goal is to define novel interaction techniques for multi-touch and tangible interfaces, which support the construction of complex queries for big(More)
We created Smart Blocks, an augmented mathematical manipulative that allows users to explore the concepts of volume and surface area of 3-dimensional (3D) objects. This interface supports physical manipulation for exploring spatial relationships and it provides continuous feedback for reinforcing learning. By leveraging the benefits of physicality with the(More)
