Mobile phones as data loggers and sensors

I previously posted an outline of a project I am working on with Will and colleagues from our Geography Department (Duncan Wyatt, Colin Pooley, Marion Moser, and Gemma Davies) which uses mobile and GPS units to both track (recording at 1 second intervals) the journey to school of 30 local children. The Geoblog app alsoallow the pupils to blog their experience along their route to create a richer picture than the route alone. A couple of people have asked me have we got any results so here is a quick taster of what we are producing and likely I will do more at a later date. A mixed methodology is used which links the data from the phones with a modelled pollution surfaces using a GIS system along personal and interviews with the pupils.
The figure below produced on a GIS system shows the journey of 3 pupils (names being pseudonyms chosen by themselves) on their journey to school. Scott cycled while Ella and Louise walked. From this we can ascertain the relative exposure levels to the pupils along the journey. An interesting point to note is the journey of Louise who cuts into the park parallel to the road and when asked in the interview about this she said it was because she didn’t like the traffic noise but was only allowed to do this at certain times in the year for personal safety. This highlights the need for a mixed methodology approach to these types of study and the power of inter-disciplinary research.
Based upon 2004, OS Landline. Map produced on behalf of The Controller of Her Majesty’s Stationary Office © Crown Copyright.
The project is producing some very interesting results and shows what interesting things we can do with our increasingly powerful phones and their potential as a very effective sensor and data gathering tool.
