Is digital
photography improving our ability of keeping and enjoying memories of our
past, or are we losing something with respect to the old printed pictures? How
should technology change to make digital pictures more useful and fun for
people?

I’ve discussed
about these issues with Siân Lindley, who is part of the Socio-Digital Systems Group at
Microsoft Research, Cambridge (UK). At CHI
2008, she is primary organizer of the workshop on Collocated social practices
surrounding photos, which is taking place today.

Digital photography is a very popular
subject. What aspects of it are you
discussing in your workshop today?
“We are discussing how photos reflect
social relationships and drive social activity. The social aspects of photos
are most evident when they are used as prompts for conversation, but they are
also manifest in the way that friends and families work together during
editing, or in how they make choices about which photos to display and which to
store out of sight. At the workshop we are thinking about how
technology can be designed to make it easier to talk about and edit digital
photos in a social context. We  also explore some new possibilities for
displaying photos, and discuss what the social implications of these might be.”

What are the major limitations of the
current devices and tools used to take, store or share digital pictures?
“The major limitations of current devices
are probably familiar to most users! People tend to have difficulties with
storing digital photos – they find it time-consuming and uninspiring
creatively, they find it hard to organize their photos in a meaningful way, and
are often concerned about how best to back them up. Often one family member is
responsible for uploading the photos, meaning that other family members can
find it difficult to understand the way the information is organised. When
sharing photos, technology is associated with a lack of intimacy. Even digital
photo displays have their problems. Daniela Petrelli and Steve Whittaker (who
will be presenting today) have found that digital frames are perceived as being too
ephemeral: they suggest that the point of displaying photos is that one chooses
special images that are worthy of display rather than having images appear at
random.”

Could you give me a few examples of
particularly interesting work that will be presented at your workshop today?
“There is a number of presentations
on how people share photos, either in different cultures (e.g. China, presented
by Connor Graham and Mark Rouncefield) or by using technologies such as mobile
phones. These obviously open up new possibilities for sharing immediately after
the event and in public places, and this has implications for how easy it is to
have a discussion around the images. A couple of presentations  also touch
on how we might support the serendipitous discovery of photos as a way of
making photo sharing more spontaneous, something which is often reported as
lacking when photos are displayed on screens.
Mobile phones and digital cameras have
also obviously had a massive influence on the way that photos are taken, and
have allowed for the emergence of the ‘snapshot video’ (so-called by Risto
Sarvas et al.). These are short video clips that sit somewhere between photos
and home movies, and which allow for a new approach to the use of video in a
social context. The workshop also includes a presentation of a mobile
photo-conferencing system (Kharsim Yousef), which supports photo sharing and
voice calls across mobile devices to bridge the gap between collocated and
remote speakers. It also allows for the joint creation of photo albums, with
friends being able to contribute, select and organise images from their own
mobiles to create a single album.
The workshop also includes two
presentations about how a sense of community can be supported through the
public display of digital photos: one in a UK village and one in a USA
workplace. The first piece of work involves a study of a public photo display
that was placed in a village hall, which resulted in villagers uploading photos
in the hope that this would help integrate new members of the community (Nick
Taylor et al.). The second was a study of a display situated in a workplace
communal area, which displayed photos from the Flickr streams of those present
(their mobile phones were detected using a Bluetooth connection). This was
found to have a positive impact on personal relationships within the
workplace.”

What sorts of new applications do you
imagine for the future, thanks to the research that is being discussed today at your
workshop?
“A good deal of research is ongoing to
support the development of tables with interactive touch screens, and a common
application of these is photo sharing and editing. Two tabletop interfaces for
the collocated sharing of photos will be discussed at the workshop, PhoTable
(Trent Apted and Judy Kay) and Photohelix (Otmar Hilliges). PhoTable allows for
users to browse and edit their photos on an interactive table, and also creates
an audio recording of the stories that are told to allow the photos to be
annotated – these annotations can then be used as a basis for tags to support
future sorting and searches. Photohelix [see illustration above] incorporates a physical device, or
‘helix’, that is placed on top of the table to support interaction. Collections of photos are arranged in a
circle from oldest to newest around the helix, which can then be spun to allow
easy access to individual images. It seems likely that on the back of work such
as this, and with current advances in tabletop technologies, interactive tables
will be used to edit and share photos in the future.
Other possibilities for the future
include applications to support the joint editing and archiving of photos, and
digital photo frames that are more sensitive to the social connotations of how
and why images are displayed.
