In my field research on The mobile phone in urban Kenyan everyday-life, I have developed a qualitative media research method that was used to collect empirical data from the field. A fully developed article on how the MediaMap exactly works as well as its theoretical and methodological framing has now been published as a book chapter:
Waltinger, Michael (2017): Die MediaMap – Eine explorative Forschungsmethode zur Entwicklung einer kontextualisierten Mediennutzungsperspektive. [The Media Map – An explorative method for researching media usage in context.] In: Knaus, Thomas (ed.): Forschungswerkstatt Medienpädagogik. Projekt – Theorie – Methode [Media Pedagogy Research Workshop: Projects – Theories – Methods.] . München: kopaed, pp. 253 – 286.
There is also an accompaniying micro-website on the MediaMap, containing a short description of the method as well as images of the development of the method, the research-setup and some examples of MediaMaps as produced by participants in my field research in Nairobi (Kenya): www.thinkbeyondborders.org/mediamap.
