Pearl: living media enabled by interactive photo projection

Abstract

Abstract:People capture more and more photographs leading to large personal photo collections that require much time and effort to organize. A lack of organization can have a negative effect on photo retrieval and photo sharing. In this user-centred design case study we have explored new possibilities for organizing and sharing photographs. To organize photographs the concept Living Media was created; automatic positive selection based on which photographs are viewed more often and viewed for a longer time. These photographs are apparently more interesting and therefore they will keep their appearance; less popular photographs will slowly fade to black over time. To share Living Media away from the computer the device Pearl was designed. Pearl has an integrated pico projector that projects an interactive collage of Living Media in a living room.Interaction with the collage, such as deleting unwanted photographs from the collage, gives input to the selection procedure of Living Media. Placing Pearl at a distance creates a larger projection size, suitable for sharing photographs with a group of people. Our design is evaluated in two small user studies, where we found benefits and challenges of using a combination of positive selection and pico projectors for photowork and photo sharing.

From PhotoWork to PhotoUse: exploring personal digital photo activities

“…Re-used with permission from ACM. (Jansen, Hoven, and Frohlich 2014), which projects multiple photos on the wall, allowing participants to select, favour, and organise the content while viewing. Despite these efforts, there is as yet insufficient understanding on how to design photo retrieval solutions that reduce the workload of curation, and focus on pleasurable photo activities.…”

Making memories

“…Many designs have been made to explore ways to interact with the cues that we currently own. Photohelix [20], Pearl [27] and NeverFadeAway [38], for instance, explore the interactive display of photos in the home environment. Caraclock [41], Cueb [16] and 4Photos [4] are also based on digital photos, but have a very social focus: photos are presented in certain combinations to spark conversations.…”

Supporting intergenerational memento storytelling for older adults through a tangible display: a case study

“…Second, organizing and archiving personal mementoes. Given the temptation to capture as much as possible results in vast personal collections scattered over disparate sources [1], applications mostly employ interactive devices, such as an interactive multi-touch tabletop [30], and a projector [31], both aiming to better organizing and retrieving personal digital content. Third, displaying and sharing personal mementoes, which are the most relevant direction to our study, and will be highlighted in this section.…”

“…Unlike digital mementoes were archived on the computer in disorganized collections of virtual folders [56], older participants carefully organized their mementoes. Maybe one reason is that prints go through a tougher selection than digital ones, while the young do not need to make a strict selection with digital photos [31]. Moreover, we could infer that older adults strongly cherished mementoes from the following detail: adding notes, theme tags, and even objects related to the photos.…”

“…Third, facilitate retrieval by building links between physical mementoes and related audios. Prior research suggests that people like to augment their mementoes with spoken stories, and physical mementoes are logical access points to the digital collection [31]. Therefore, to make easy accessing to digital collections, building links between physical mementoes and related audios could be one option, as discussed in Sect.…”
