This paper borrows ideas from social science to inform the design of novel "sensing" user-interfaces for computing technology. Specifically, we present five design challenges inspired by analysis of human-human communication that are mundanely addressed by traditional graphical user interface designs (GUIs). Although classic GUI conventions allow us to(More)
We describe a new approach to information retrieval: algorithmic mediation for intentional, synchronous collaborative exploratory search. Using our system, two or more users with a common information need search together, simultaneously. The collaborative system provides tools, user interfaces and, most importantly, algorithmically-mediated retrieval to(More)
While predictions abound that electronic books will supplant traditional paper-based books, many people bemoan the coming loss of the book as cultural artifact. In this project we deliberately keep the affordances of paper books while adding electronic augmentation. The Listen Reader combines the look and feel of a real book - a beautiful binding, paper(More)
People can help other people find information in networked information seeking environments. Recently, many such systems and algorithms have proliferated in industry and in academia. Unfortunately, it is difficult to compare the systems in meaningful ways because they often define collaboration in different ways. In this paper, we propose a model of(More)
We describe Cerchiamo, a collaborative exploratory search system that allows teams of searchers to explore document collections synchronously. Working with Cerchiamo, team members use independent interfaces to run queries, browse results, and make relevance judgments. The system mediates the team members’ search activity by passing and reordering search(More)
The modern workplace is inherently collaborative, and this collaboration relies on effective communication among co-workers. Many communication tools -- email, blogs, wikis, Twitter, etc. -- have become increasingly available and accepted in workplace communications. In this paper, we report on a study of communications technologies used over a one year(More)
/ The physical world can be augmented with auditory cues allowing passive interaction by the user. By combining active badges, distributed systems, and wireless headphones, the movements of users through their workplace can trigger the transmission of auditory cues. These cues can summarize information about the activity of colleagues, notify the status of(More)
The expressiveness of touch input can be increased by detecting additional finger pose information at the point of touch such as finger rotation and tilt. PointPose is a prototype that performs finger pose estimation at the location of touch using a short-range depth sensor viewing the touch screen of a mobile device. We present an algorithm that extracts(More)
Sound design for large interactive systems poses unique challenges, many of which are illustrated in the complex set of instmments and games that were built for the interactive installation/perfortnance Brain Opera. Three design and differentiation processes for these interactive artifacts sre deseribed: conceptual design system design, and acoustic(More)
