I have always wondered about uses for an always-available camera such as what Nokia Samsung etc. supply in just about any cellphone on the planet.
What about putting the cellphone in a cradle when driving, so the cellphone camera can look out in front. Then, a Java applet that is activated with the
touch of a key at the beginning of a drive will record the last minutes of what happens in front of me.
If there is a minor accident, I archive the last minutes of what happened in the road by pressing a button.
The recorded material could be used to prove who caused the accident. That is, if police accept it as evidence.
If there is a major crash, after which I'm unable to do anything, hmm... ...I guess archiving the last minutes would have to be triggered by a sudden-deceleration-sensor. That is, if the phone survives the crash. OK, leave it for V 2.0.
