In February 2006, one of Gapminder’s founders Hans Rosling gave a TED talk that demonstrated the most effective aspect of Gapminder’s data visualisation, that is, how data changes over time. In a graph that displayed UN statistics of the number of children per family juxtaposed with life expectancy for a number of countries, Rosling takes us through the changes from 1962 to 2003 like a sportscaster calling a horse race as countries represented by animated, colour-coded dots that grow and shrink as they move across the axes.

The Gapminder site offers both static and dynamic materials in the form of PDFs and clickable flash presentations/applications, but the main draw is Gapminder World, where you can create your own animated data-visualisation by investigating whichever countries and using whatever parameters that interest you.

As the user goes about their day, the bio sensors capture real-time information on their physical states, including pulse, movement, skin temperature and galvanic skin response. At the end of the day, when the user syncs the collection devices to the tablet, the software interprets the bio data and represents the user’s emotional and physical states as colourful body shapes in positions ranging from fully reclined to upright. The colour of the shapes represent emotional states, with blue for the calm/rested end of the scale, red for the other aroused/agitated extreme, and gradations of purple for the states in between. Whether the shapes are more horizontal or vertical indicates that the user is moving around a lot or a little, respectively. Text messages that the user has received throughout the day, and photos they have taken are also uploaded to the diary from their mobile phone. All this bio and social data is then overlaid on a timeline of the user’s day.

The user can then navigate their diary by scrolling through this timeline and looking at sections of their day and the data associated with it. Photos they have taken are displayed in stacks according to their timestamp, and circular symbols that represent text messages received can be clicked on to reveal their contents. The user also has the ability to write or draw on these sections – perhaps notes on where they were, who they were talking to – adding another layer of narrative.

High-res screen captures can be viewed here and there is a video with more information on how to use the system here.

Affective Diary was developed in the Interaction Lab at the Swedish Institute of Computer Science (SICS) in cooperation with Microsoft Research. Participants in the project are: Kristina Höök, Martin Svensson, Anna Ståhl, Petra Sundström and Jarmo Laaksolathi, SICS, Marco Combetto, Alex Taylor and Richard Harper.

Since the start in 1998, their work has been characterized by not only conducting traditional academic research but also exploring the borders between art, design and technology, industry and academy, etc. The institute has about 60 employees organized in a number of research studios/groups located in Kista/Stockholm, Piteå, Eskilstuna, Norrköping, Växjö and Göteborg. Each research group has its own focus area that relates to the overall focus of combining technology with art and design.

The Interactive Institute has a number of research groups within it such as Digital Cultural Heritage Centre which looks at issues such as cultural knowledge transfer in new media and technologies, The Design Research Centre which seems concerned with developing big-picture research strategies, Sound Studio and SoundSpace groups working in interactive sound design, NVISION working with visualisation techniques and Mobility Studio which looks at, well, developments in the use of mobile technologies.

The Mobile Life Centre at Stockholm University has a research focus that spans from social and entertainment and work aspects of mobile technologies, affective engagement and ubiquitous computing. Set up as a 10 year funding project by VINNOVA – (The Swedish Governmental Agency for Innovation Systems), which is a State authority that aims to ‘promote growth and prosperity throughout Sweden’ through funding ‘innovations linked to research and development’. The Centre names the Interactive Insitute and the Swedish Insitute of Computer Science as collaborative partners, and also list a number of industry partners including Sony Ericsson, Microsoft Research and Stockholm Innovation and Growth. The centre lists around 20 PhD students and Professorial staff on its list of researchers and lsome of the more interesting research projects include:

Mobile Eco-System

The future mobile eco-system – who pays for what? And what does it feel like? A future mobile service eco-system where we explore alternative universes for infrastructure, business models and the industry’s new role.

Embodied Affective Interaction

Interact emotionally with your whole body. New mobile and ubiquitous services in areas such as pervasive games, social, emotional and bodily communication and new mobile media.

There is also an interesting list of seminars on topics such as the following:
Beyond representations: Towards an action-centric perspective on tangible interaction

Mobile Collaborative Live Video Mixing

Affective Loops : research agenda for bodily persuasion through a design approach we name affective loops is outlined. Affective loop experiences draw upon physical, emotional interactions between user and system.

Whilst this begins to appear quite the complex web of tangled connections, it seems that one common link and hence potentially a good interview subject might be Professor Kristina Hook . She is Professor at Mobile Life, as well as Lab Manager at Swedish Institute of Computer Science, and Professor of Human-Machine Interaction at the Dept of Computer and Systems Science (a joint venture between Stockholm University and Royal Institute of Technology, Kristina Hook lists research projects in embodied interaction and ‘affective computing’ among her interests. Particularly notable is the research project which has involved Microsoft Research called Affective Diary, which investigates techniques data-mapping diary of galvanic skin response via mobile technologies, and seems to have spawned collaborative projects such as a sound design project which looks at sonification techniques using the data sets generated by Affective Diary.
