Examining the impact of collaborative tagging on sensemaking in nutrition management. In Proceedings of the 2011 annual conference on Human factors in computing systems (CHI ’11).
Collaborative tagging mechanisms are integral to social computing applications in a variety of domains. Their expected benefits include simplified retrieval of digital content, as well as enhanced ability of a community to makes sense of the shared content. We examine the impact of collaborative tagging in context of nutrition management. In a controlled experiment we asked individuals to assess the nutritional value of meals based on photographic images and observed the impact of different types of tags and tagging mechanisms on individuals nutritional sensemaking. The results of the study show that tags enhance individuals’ ability to remember the viewed meals. However, we found that some types of tags can be detrimental to sensemaking, rather than supporting it. These findings stress the importance of tagging vocabularies and suggest a need for expert moderation of community sensemaking.

The continuing epidemics of diabetes and obesity create much need for information technologies that can help individuals engage in proactive health management. Yet many of these technologies focus on such pragmatic issues as collecting and presenting health information and modifying individuals’ behavior. We argue that viewing health management from an identity construction perspective opens new opportunities for research and design in technologies for health.

Medynskiy, Y., Miller, A., Yoo, J.W., Mynatt, E. Temporal Data in a Health Self-Management Application. Presented at the Interacting with Temporal Data workshop at CHI 2009.
In this position paper, we present our initial work in designing and developing Salud!, a web-based platform for supporting health self-management. Salud! will allow its users to track personally-relevant aspects of their everyday life, and provide visualization and analytics tools with which to make sense of the resulting datasets.

Miller, A. and Edwards, W. Give and Take: A Study of Consumer Photo-Sharing Culture and Practice. Proceedings of the SIGCHI conference on Human factors in computing systems, ACM (2007), 356.
In this paper, we present initial findings from the study of a digital photo-sharing website: Flickr.com. In particular, we argue that Flickr.com appears to support—for some people—a different set of photography practices, socialization styles, and perspectives on privacy that are unlike those described in previous research on consumer and amateur photographers.
