Mechanisms for Collaboration: A Design and Evaluation Framework for Multi-User Interfaces - ToCHI
Contribution & Benefit: Comprehensive conceptual framework for considering design and evaluation dimensions for how multi-user interfaces can best support collaboration in work and play across the range of users.
Abstract » Multi-user interfaces are said to provide new opportunities for users to benefit from
‘natural’ interaction in supporting collaboration, compared to individual and non-colocated
technologies. We identify three mechanisms potentially accounting for the
success of such interfaces: high levels of awareness of others, high levels of control
over interface and high levels of transparency of background information. We
challenge the idea that interaction over such interfaces is necessarily ‘natural’ and
argue that everyday interaction involves constraints on awareness, control and
transparency. These constraints support smoother interaction. We present a
framework characterizing the design of multi-user interfaces in terms of how
constraints can be best used to promote collaboration, based on how these
mechanisms support transparent and salient interactions. We use this framework first
to explain successes and failures of existing designs, then apply it to three case
studies, and finally derive criteria for use in designing multi-user interfaces for
Diversity among Enterprise Online Communities: Collaborating, Teaming, and Innovating through Social Media - Paper
Community: management
Contribution & Benefit: We describe different types of enterprise online communities, with implications for community success metrics, tools to support those communities, organizational design, and theories of online communities and virtual teams.
Abstract » There is a growing body of research into the adoption and use of social software in enterprises. However, less is known about how groups, such as communities, use and appropriate these technologies, and the implications for community structures. In a study of 188 very active online enterprise communities, we found systematic differences in size, demographics and participation, aligned with differences in community types. Different types of communities differed in their appropriation of social software tools to create and use shared resources, and build relationships. We propose implications for design of community support features, services for potential community members, and organizations looking to derive value from online groups.
Homeless Young People on Social Network Sites - Paper
Community: design
Contribution & Benefit: Contributes to the HCI literatures on homelessness and social network sites. Provides implications for social intervention and technical design related to social network sites and homeless young people.
Abstract » This paper reports on the use of social network sites (MySpace and Facebook) by homeless young people, an extraordinary user population, made so in part by its vulnerability. Twenty-three participants of diverse ethnicities, 11 women and 12 men (mean age, 21.7 years), were interviewed in same-sex discussion groups of four participants each. The interviews consisted of questions about the uses, benefits, and harms of social network sites and how people present themselves online. Qualitative analysis of the discussion group transcripts shows how young people explore their identities, cultivate and exploit social ties, experience interpersonal tensions, manage incompatible audiences, and respond to shifting affiliations and transitions. From this analysis, implications for social intervention and technical design are presented, focused on maintaining ties with pro-social family and friends and with maintaining separation between communication spheres of incompatible audiences. This work contributes to the growing literature on vital, deeply human experiences that have become associated with social network sites.
Supporting the Social Context of Technology Appropriation: On a Synthesis of Sharing Tools and Tool Knowledge - Paper
Community: management
Contribution & Benefit: We introduce a holistic appropriation support approach, using Eclipse as an example. We address especially the entanglement of social aspects (learning, trust) and technical aspects (tailoring, configuring, installing) of appropriation.
Abstract » There is an increasing spread of flexible software applica-tions that can be modified by adding components (some-times called plug-ins or add-ons). A popular example in the software development domain is Eclipse, a flexible devel-opment environment that can be extended with literally thousands of different plug-ins. However, searching, in-stalling and configuring new plug-ins requires complex overhead work that is only weakly addressed by existing support mechanisms. Recent research has highlighted the related practices of learning about new plug-ins and tailor-ing software tools as being highly cooperative, situated, socially embedded, and often connected to particular work situations. Based on an empirical study in small software enterprises, we develop an understanding of appropriation as a social and collaborative activity. We then suggest de-sign principles for appropriation support that are grounded in the practices we have found in the field, and present a prototypical implementation of the concept that extends existing mechanisms of sharing tools and tool-knowledge.
