IF Lab is designed to help creatives to produce and develop their online factual interactive stories.Interactive factual stories can be any creative project that uses digital interactive media to portray factual issues: online journalism, i-docs (interactive documentaries), serious games, historical graphic novels for the iPad, media rich NGO websites, museum installations or locative and educational apps (see http://docubase.mit.edu/ for some examples).At the moment interactive factual narratives are exploding online, and on mobile media, but very little methodologies are known (let alone implemented, used, refined and re-used) to work in this new field at the intersection between documentary, journalism, social communication and web design. A safe space for experimentation is needed where project are followed during their production so that a new breed of creative technologist and digital storytellers can grow stronger and start spreading their know-how to others. At the moment many interactive projects seem to be initiated by storytellers (film directors, documentary makers or writers) and yet most of them never manage to be produced because multi-disciplinary teams are hard to form (they belong to different networks) and people are not used to work together in a collaborative and agile way. Matching skills from different sectors for a sustainable creative industry seem to us to be key in the present industry.IF Lab offers 3 x 4 days booster sessions, focussing on story, design and code. These sessions are linked to a documentary festival in Belgium, an innovation conference in Sweden and a tech & code happening in London. We aim for a group of 20 people participating the Lab. Besides we create webinars about the booster sessions for another 200 people being able to join online.
