NOxDROID v 0.1

One comment

The NOxDROID was presented today to our teachers and fellow students at ITU. The project paper was also handed in and can hopefully be submitted for CHI 2012

Overall the we are quite content with the outcome, and intend to keep on working on the NOxDROID. It is still in an early alpha version 0.1 with a lot of technical issues to deal with.

First of all we need to look at the recording of data. Currently the locationtracking is using both Skyhook (network and cell towers) and the phoe's own location services (gps, network, cell towers) resuting in redundancy and many identical location readings. Both updateintervals and accuracy need to be tuned to the needs of the application. 

A lot can be done to reduce redundancy by tuning parameters but a better dataprocessing and cleaning is also necessary when generating kml data for the map overlay. The amount of kml data that can be rendered by google maps javascript api is limited. Hence we might need to process the data further to fit the web based visualization. 

Other challendes of the visualization includes overlay of overlapping data for a given time span. This includes averaging over geospatial clusterings of data. This could possibly be done using the GeoModel of the Google's App Engine to do geospatial queries by proximity or the bounding box model.
