I wonder if anybody has any ideas that might help me as I stuck on a uni project.
Basically, I need to create (only theoretically) a device which is basically a push button tool that detects where you are (GPS of course) and then displays emergency contact information for your area (i.e. a list of doctors, dentists, chemists, etc...)
The data will ofcourse be stored on a database on a server elsewhere and can be sent to the device via SMS, GPRS, 3G, anything really... but anyway... this thing can't be a phone, or a PDA. It has to be just a tool that provides the described purpose alone.... Help... please... does something like this exist already? Will it need a whole mobile OS to work? Where do I start with what hardware will be required??
Thanks in advance for any ideas.
