My project will be the same that I mentioned on assignment 4, the SafeBand. So, It will be a small device connect via Bluetooth to a smartphone app.  The device will have a little button, when the button is pressed, the fit band will send a signal to the smartphone , sending  a e-mail/text message with the user location to a pre-registered list of people informing that the user is in some kind of dangerous situation.

A possible implementation would be to add a sensor that monitor the life signals from the user, and if it’s below a certain value we would alert his contacts as explained above.

The challenges that we might face on this project would be:

• Find a hardware small enough to fit on a fitband. ( Maybe in the prototype we would use something bigger)
• Battery life ( We will have to figure out a way to put the Bluetooth on a sleeping mode or something similar)
