<DIV></DIV>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><BR>-Kyle<BR><BR><BR>

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><BR>--<BR>Alexey Feldgendler <<A
