I would like to see cell phones that have a panic button that could be activated if someone was being attacked. The button would be textured so that it could be identified by feel even if it couldn't be seen. It would have a depress-and-slide mechanism so it couldn't be set off accidentally (and there would be a hefty fine if it were set off "accidentally" more than once). On activation, the phone would sound a loud siren, and 911 would be dialed automatically, with the phone going to loudspeaker mode so the attacker would know that 911 had been called. The GPS in the phone would permit the police to locate the attack. The 911 dispatcher would know that the call was from a phone panic button and would send help even if the person calling could not respond.

This may well exist already as a stand-alone device, but people are far more likely to be able to reach their cell phones quickly. In fact, they're probably walking along talking on their phones already, which is why they didn't notice that someone was sneaking up on them in the first place!

Reward: 1. The satisfaction of knowing that some muggings and rapes had been thwarted. 2. Free phones for my family.

Most people don't know this mainly because nobody tells us: Almost all phones with actual keys(like a razor, not like an iphone) will allow you to dial 911 without unlocking the keypad. try it out some time. I figured this out 10 years ago when I had a nokia 5160 and it's worked on every phone I've tried it on since then.

I think you have a great idea and in no way am I suggesting that this is an equal alternative. I just think that everyone should know how they can dial 911 faster given our current technology.

This could be great technology for those who have GPS on their phone. I think every phone has 911 number saved on it which be use in case of emergency. You just have to press a fast dialing button on which 911 is saved and your call lands to 911. Correct me if I am wrong.

Already exists, I had a cellphone where I had to press both the volume up and down at the same time for three times and it would call 911.
