Cellphone location coasters

Paper mats that alter cellphones' behaviour

It is useful to have one's cellphone behave differently in different locations - e.g. ring loudly when outdoors, softly in the office, or vibrate when in a pocket.

GPS can be used for some of these situations, but isn't as useful indoors or for very small changes in location.

Small, clearly marked paper mats could be left in various locations - office desk, office drawer, car cubbyhole, bedside table. The cellphone's built-in camera could identify which mat it had been placed on by reading a special pattern printed thereon. The cellphone could then be instructed on how to behave on each mat:

Office desk --> ring quietly if called

Office drawer --> keep quiet

Car cubbyhole --> look for bluetooth car kit, or take a message

Bedside table --> wake me up in time for my first meeting

       [+] good spot for inductive charging too.

       This would be good, although I guess it wouldnt be long before it would be used for advertising.   

       This may not be a bad thing though, especially if merged with wireless charging: "Put your phone here to charge and download information about the new coors extra light - so light it tastes like crisp clean yellow snow."
