Suppose I have an array of cell phones, each having:
- an accelerometer
- a clock
- a GPS receiver
- Windows Phone 7 (WP7)
How hard would it be to write a program so that synchronizes the phones to a common clock (preferably a GPS clock)?
How hard would it be to write a program that starts recording accelerometer readings when it receives text message? I would want it to collect for a duration specified in the text message, and then forward the collected data (including location) back to an address specified in the text message.
How hard would it be to write a program (on a PC or a cell phone) that recieves the data, processes it to compute a "fix" (ellipse) on the source signal location, then sends that fix back to each cell phone as a text message?
Alternatively, could I record audio spectrograms instead of accelerometer readings?
