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)
medium to create a peripheral display. Our goal is to leverage these natural abilities and create an interface that enriches the physical world without being distracting. The information we provide via Audio Aura is designed to be serendipitous. You appreciate it when you hear it, but you do not rely on it in the same way that you rely on receiving an email(More)
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)
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)
/ 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 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)
Reading is part of how we understand the world, how we share knowledge, how we play, and even how we think. Although reading text is the dominant form of reading, most of the text we read letters, numbers, words, and sentences is surrounded by illustrations, photographs, and other kinds of symbols that we include as we read. As dynamic displays migrate into(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)
What does a student need to know to be a designer? Beyond a list of separate skills, what mindset does a student need to develop for designerly action now and into the future? In the excitement of the cognitive revolution, Simon proposed a way of thinking about design that promised to make it more manageable and cognitive: to think of design as a planning(More)
