CSCW research examples:From ethnographic studies to working prototypes John C. Tang October 30, 2007
NEEDS DESIGN EVALUATE IMPLEMENT Research: Using video to support collaboration • My research focuses on supporting collaboration (CSCW) • Uses ethnographic studies for need-finding • Example of design process, differences from popular trends
Popular: High fidelity video conferencing • Cisco Telepresence • HP Halo • Polycom Real Presence Experience High fidelity video and audio
Cisco Telepresence • Target audience: Company Executives • Rules of Telepresence • Present far end participants life size • Provide virtual eye contact • Do not pollute visual display with distractions Are these the main needs for successful everyday collaboration?
Apple iChat AV • Integrated into all Macintosh computers • Very easy to use • Attractive graphical presentation Are these the main needs for successful everyday collaboration?
Awareness cues for remote collaboration • Hard part is social problem • Gracefully sharing a workspace • Cues for negotiating interaction lost among remote collaborators (i.e., phone) • Review research prototypes for remote collaboration • VideoDraw • VideoWhiteboard Innovation in mediated support for collaboration
Ethnography Branch of anthropology that deals with the scientific description of specific human cultures • Typically applied to study of foreign cultures • More recently applied to work cultures or simply users of technology
Ethnographic studies of collaboration activity • Studying pairs and teams of people working together
Shared workspace • Creating an engaging, interactive shared workspace among remote collaborators • Sharing awareness cues that enable collaborators to negotiate • Graceful turn-taking • Gestures with respect to drawings • Showing the process of creating drawings • Sharing space • Building on each others’ work
VideoDraw shared drawing space • Based on empirical studies of teams engaged in conceptual design • Series of video-based prototypes for creating a shared drawing surface • Table-sized VideoDraw • Whiteboard-sized VideoWhiteboard • Built in a Media Space environment Xerox PARC Scott Minneman and Media Space team
VideoDraw circa 2007 • Recently announced Microsoft Surface • Research prototype application http://www.popularmechanics.com/blogs/technology_news/4213259.html
Ethnography in HCI design • Identifying user needs • Sharing workspace • Design implications for innovative technology Enabling doing new things in familiar ways
