- ItemOpen AccessSharing Digital Photographs in the Home by Tagging Memorabilia (Video)(2008-10-20T22:07:31Z) Greenberg, Saul; Nunes, MichaelPeople now easily share digital photos outside the home via web publishing and gift-giving. Yet within the home, digital photos are hard to access and lack the physical affordances that make sharing easy and opportunistic. To promote in-home photo sharing, we designed Souvenirs, a system that lets people link digital photo sets to physical memorabilia tagged with RFID markers. These memorabilia trigger memories and create opportunities that serve as social instruments for sharing. A person can show photos by moving the physical memento close to their large television screen, and the associated photos are immediately displayed. Alternately, they can bring a mobile computer to the souvenir, which shows the photos there. Using pick and drop, photos appearing on the mobile device can be quickly displayed on the large television.
- ItemOpen AccessSharing Digital Photographs in the Home through Physical Mementos, Souvenirs, and Keepsakes(2007-08-08) Nunes, Michael; Greenberg, Saul; Neustaedter, CarmanPeople now easily share digital photos outside the home via web publishing and gift-giving. Yet within the home, digital photos are hard to access and lack the physical affordances that make sharing easy and opportunistic. To promote in-home photo sharing, we designed Souvenirs, a system that lets people link digital photo sets to physical memorabilia. These mementos trigger memories and serve as social instruments; a person can enrich their storytelling by moving the physical memento close to their largeformat television screen, and the associated photos are immediately displayed. We implemented Souvenirs, and then reexamined our design premises through contextual interviews with 20 households. Families described their current practices of photo sharing and memento use, and also reacted to the Souvenirs design. Based on these interviews, we redesigned Souvenirs to better fit the real practices of photo and memento use in the home
- ItemOpen AccessUsing Physical Memorabilia as Opportunities to Move into Collocated Digital Photo Sharing(2009-02-27T22:55:29Z) Nunes, Michael; Greenberg, Saul; Neustaedter, CarmanThe uptake of digital photos vs. print photos has altered the practice of photo sharing. Print photos are easy to share within the home, but much harder to share outside of it. The opposite is true of digital photos. People easily share digital photos outside the home, e.g., to family and friends by email gift-giving, and to social networks and the broader public by web publishing. Yet within the home, collocated digital photo sharing is harder, primarily because digital photos are typically stored on personal accounts in desktop computers located in home offices. This leads to several consequences. 1) The invisibility of digital photos implies few opportunities for serendipitous photo sharing. 2) Access control and navigation issues inhibit family members from retrieving photo collections. 3) Photo viewing is compromised as digital photos are displayed on small screens in an uncomfortable viewing setting. To mitigate some of these difficulties, we explore how physical memorabilia collected by family members can create opportunities that encourage social and collocated digital photo sharing. First, we studied (via contextual interviews with 20 households) how families currently practice photo sharing and how they keep memorabilia. We identified classes of memorabilia that can serve as memory triggers to family events, trips, and times when people took photos. Second, we designed SOUVENIRS, a photo-viewing system that exploits memorabilia as a social instrument. Using SOUVENIRS, a family member can meaningfully associate physical memorabilia with particular photo sets. Later, any family member can begin their storytelling with others through the physical memento, and then enrich the story by displaying its associated photos simply by moving the memento close to the home's large-format television screen. Third, we re-examined our design premises by evoking household reactions to an early version of SOUVENIRS. Based on these interviews, we redesigned SOUVENIRS to better reflect the preferences and real practices of photo and memorabilia use in the home.
- ItemOpen AccessWhat Did I Miss? Visualizing the Past through Video Traces(2007-04-16) Nunes, Michael; Greenberg, Saul; Carpendale, Sheelagh; Gutwin, CarlAlways-on media spaces broadcast video between collaborators to provide mutual awareness and to encourage casual interaction. This video can be easily recorded on the fly as a video trace. Ostensibly, people can review this video history to gain a better idea of the activities and availability of their collaborator. Such systems are obviously highly contentious, as they raise significant privacy concerns. However, the ease of capturing video means that video trace systems will appear in the near future. To push the boundaries and encourage debate about video trace technologies within the CSCW community we created TIMELINE, a highly effective visualization system that combines ideas in slit scanning as used in interactive art to allows people to easily and rapidly explore a video history in detail. We describe its design and implementation, and begin the debate by offering preliminary reflections on how it can be used and misused. To encourage this debate, TIMELINE is freely available for others to try.
