The goal of this research is to build upon the work of capturing data in structured and planned settings to develop socially appropriate ways to archive important life experiences during unexpected, unstructured, and sometimes informal situations. This ...

Widespread adoption of collaborative authoring tools (such as Wikis) by online communities has fostered new ways of storing, sharing, maintaining, and using community knowledge. My dissertation research examines the effect and potential use of these ...

The objective of this paper is to set the research agenda for a workshop focusing on novel approaches to supporting trust, collaboration, and compliance in social systems. Suggested approaches are: self-awareness, reparative and social recommender ...

We summarize the motivation and aims for this workshop on usability research challenges for cyberinfrastructure and tools, and outline workshop preparations and program.

Cyberinfrastructures bring together distributed resources to support scientific discoveries. Cyberinfrastructures currently under development are intended to enable the cooperative work of diverse users over long periods of time. We analyze the ...

We developed a set of visualization techniques to portray multiple threads or trajectories of events and activities to provide awareness support. Visualizing the historical and projected temporal patterns of trajectories may provide support to ...

The sharing of network-based information is a key component of recreational and professional interaction, from email attachments to P2P networks. However, people need to accommodate technical challenges in successful and secure content sharing. In ...

We present a computer-based tool for the support of collaborative sketching activities in design: Public Social Private Design (PSPD). We provide an overview of the empirical studies that have informed the development of PSPD. We present the current ...

This paper presents an on-going investigation on interruptions in the office caused by face-to-face interactions between knowledge workers. The study aims to identify opportunities for interactive solutions that will support both, the interrupters and ...

Aggregate pointers, a new type of telepointer, can be used to support the collaboration of many people in interactive environments. An aggregate pointer can make it easy for people to understand the overall direction of others' intentions or interests, ...

Recent years have seen an increasing use of collaboratories in distributed scientific work. This study examines the role of collaboratories in informal scientific communication. Hypotheses relating to potential opportunities for informal communication ...

Although a lot of systems provide co-located collaboration support, few existing technologies provide support for fluid knowledge sharing. To fluidly share our knowledge in co-located environments, each person's digital experience should be merged and ...

We describe innovative new work in the development of an "animated architecture." Specifically, we describe our early research aimed at the creation of intelligent, programmable, physical spaces supporting working life. Our research takes advantage of ...

We present a visualization system for reviewing the turn-taking patterns in a face-to-face meeting. Without the need to directly observe a group, a user can use the system to gain insight into the interaction dynamics of a meeting. We evaluated the ...

This work in progress reports a study of cross-cultural collaboration mediated by board-based collaborative systems. American-Chinese and American-American pairs performed collaborative design tasks either face-to-face or remotely. Survey data, video ...

A comparison of the accuracy of comprehension of Instant Messaging (IM) messages composed using a keyboard, handwriting recognition and speech recognition was performed. The participants in the study were shown text messages either containing no errors ...

Online health communities provide a means for patients and their families to learn about an illness, seek and offer support, and connect with others in similar circumstances. They are supported by a variety of technologies (e.g., email lists, forums, ...

This paper presents research on a collaborative learning environment in an urban elementary science classroom. The application, called RoomBugs, simulates a dynamic ecosystem of insects within the physical space of a classroom. Using table-mounted ...

In this paper we describe the design behind the Bloom Diagram, a tool to visualize the evolution of individual participants' code and comment contributions to open source software projects. The design blends techniques such as concentric pie charts, ...
