Cosley, Dan, Baxter, Jonathan, Lee, Soyoung, Alson, Brian, Nomura, Saeko, Adams, Phil, Sarabu, Chethan and Gay, Geri (2009): A tag in the hand: supporting semantic, social, and spatial navigation in museums. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 1953-1962.

“Designers of mobile, social systems must carefully think about how to help their users manage spatial, semantic, and social modes of navigation. Here, we describe our deployment of MobiTags, a system to help museum visitors interact with a collection of "open storage" exhibits, those where the museum provides little curatorial information. MobiTags integrates social tagging, art information, and a map to support navigation and collaborative curation of these open storage collections. We studied 23 people's use of MobiTags in a local museum, combining interview data with device use logs and tracking of people's movements to understand how MobiTags affected their navigation and experience in the museum. Despite a lack of social cues, people feel a strong sense of social presence -- and social pressure -- through seeing others' tags. The tight coupling of tags, item information, and map features also supported a rich set of practices around these modes of navigation.”

Cosley, Dan, Akey, Kathy, Alson, Brian, Baxter, Jonathan, Broomfield, Mark, Lee, Soyoung and Sarabu, Chethan (2009): Using technologies to support reminiscence. In: Proceedings of the HCI09 Conference on People and Computers XXIII 2009. pp. 480-484.

“This paper is about the evolution of a system prototype called Pensieve whose goal is to support people's reminiscing practices. A number of technologies exist to manage memory-related content; however, these technologies tend to take a model of memory as information that leads to a focus on capture and access. Pensieve is instead based on reusing memory-laden content people already create in social media services. This idea is supported by theories of autobiographical memory, insights from interviews with eight subjects, and experiences with two prototypes deployed to ten users. These interviews and experiences suggest that people value even simple tools that support reminiscence, as well as providing both design goals and research questions around the design of tools that support people in reminiscing.”
