HRI researchers interested in social robots have made large investments in humanoid robots. There is still sparse evidence that peoples' responses to robots differ from their responses to computer agents, suggesting that agent studies might serve to test HRI hypotheses. To help us understand the difference between people's social interactions with an agent and a robot, we experimentally compared people's...
The Internet is widely valued for distributing control over information to a lateral network of individuals, but it is not clear how these networks can most effectively organize themselves. This paper describes the distributed networks of volunteers that emerged online following Hurricane Katrina. Online communities responded to the disaster by facilitating the distribution of donated goods from ordinary...
What role can social networking Websites play in supporting large-scale group action and change? We are proposing to explore their use in supporting individual reduction in personal energy consumption. In this we summarize some existing uses of social networking on the Web and propose an approach that integrates feedback about ecological footprint data into existing social networking sites and Internet...
Prior research suggests people have trouble juggling effort across multiple projects with multiple partners. We investigated this problem, with an experiment where groups of four participants enacted the roles of police detectives. Each detective was assigned two homicide cases, each case with a different partner. To solve each case, detectives read their case documents and discussed relevant information...
Eastern and Western cultures differ along several dimensions affecting computer-supported collaborative work. We consider one such dimension, low context (requiring little situational information) or high context (requiring substantial situational information) communication style. Specifically, we report on a laboratory study comparing communication and performance of low-context American dyads, high-context...
Hospital surgery environments are dynamic and high risk. They require coordination across multiple groups whose incentives, cultures, and routines can conflict. In this paper, we describe a field study of multi-group coordination in the operating room (OR) environment. We studied work trajectories from the perspective of each group involved. Coordination breakdowns at group boundaries involving patients,...
Coordinating activities in many settings can require people to manage conflict, potential and actual. Conflict arises from resource limitations, high-stakes consequences, uncertainty, goal conflict among stakeholders and hierarchical organizational structures. To understand coordination in such systems, we conducted a field study of management of surgical operating rooms. While coordinating interdependencies,...
