For the City Velocities – Body Speeds project, we needed to measure the speed of trams that move through the city.

Because a smart phone has a couple of sensors built-in and is capable of uploading data to a remote server, we chose Android as a base platform to work with. However, we needed to find out which phone had the best sensors to do this, i.e. which phones had sensors that were most accurate.

By making a call for help where we asked people to run a program on their phones and send us back the information on the sensors in the phone that the program reported, we got a reasonable overview of which sensors are in which phone, and their accuracy.

The results are listed in the two pdf’s down here:
