I think your examples are very possible. "Kind of reaching" would be something like trying to detect the type of jacket the person is wearing based on how much the fibers stretch during each step...or whether their jacket is open, by measuring the horizontal swinging motion. If the acceleration curve is very crisp, then the phone is prolly in their pant pocket. ;-) but I still say these things are not *impossible*, just require some very intuitive software.<br>

* I mentioned this in another thread, but if the device:<br>
- goes from 60km+ to 0 in short order, e.g. high g stop<br>
- while traveling horizontally<br>
- over a road<br>
- an on-screen alert/countdown is not stoped<br>
Then it's likely a vehicular accident so auto-call/sms for help with<br>
some kind of countdown to disable. Only really possible to do that with<br>
a phone + GPS + acell.<br>
<br>
* Sense when the owner is in a car by keying on the vibration signature<br>
and acceleration, possibly with gps data, and automatically bring up the<br>
assigned travel/map application.<br>
<br>
* Use acell data to charecterize person carrying the phone (as many<br>
couples out there will share phones, or give to children) and tie into<br>
user profile.<br>
<br>
* Detect when phone has dropped out of ones pocket, short fall by aprupt<br>
stop, beep three times loudly. (that's kind of reaching..)<br>

Subject: Accelerometer brainstorming<br>
<br>
<br>
Just like my recent post about using GPS to enhance the phone, I'll try<br>
to<br>
explore the synergy opportunities for the accelerometers that Neo has.<br>
Once again, some of this might have already been discussed.<br>
<br>
* Intuitive mute: put the ringing phone on a flat horizontal surface<br>
(table) with its screen facing down to stop the ringing. Intuitive for<br>
the<br>
user and easy to detect with the accelerometers. Could also be used to<br>
hang up the current call. The gesture is very distinguishable and is<br>
hard<br>
to misinterpret because there aren't many situations when the user would<br>
<br>
normally put the phone on the table screen down.<br>
<br>
* Vibration control: when the phone is lying flat, either with its<br>
screen<br>
up or down, don't vibrate, so as to not produce the annoying loud noise.<br>
<br>
Ring instead, or do something else. Maybe make a weaker vibration, if<br>
the<br>
vibrator can do that.<br>
<br>
* Step counter: use the accelerometers to count steps when walking or<br>
running. Some people use dedicated devices for that.<br>
<br>
* GPS power saving: you can't move if you don't accelerate, so don't do<br>
<br>
power-expensive location detection until acceleration is detected. Once<br>
<br>
it's detected, start monitoring the location and keep doing it. Stop<br>
monitoring once the position stops changing for a while.<br>
<br>
