Thanks. This package's guts might work as a starting point for gesture recognition. Prob some other fos out there sw does similar things. http://www.risujin.org/cellwriter ________________________________

"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. -Kyle On Fri, Mar 28, 2008 at 12:59 PM, Crane, Matthew <[EMAIL PROTECTED]> wrote: * I mentioned this in another thread, but if the device: - goes from 60km+ to 0 in short order, e.g. high g stop - while traveling horizontally - over a road - an on-screen alert/countdown is not stoped Then it's likely a vehicular accident so auto-call/sms for help with some kind of countdown to disable. Only really possible to do that with a phone + GPS + acell. * Sense when the owner is in a car by keying on the vibration signature and acceleration, possibly with gps data, and automatically bring up the assigned travel/map application. * Use acell data to charecterize person carrying the phone (as many couples out there will share phones, or give to children) and tie into user profile. * Detect when phone has dropped out of ones pocket, short fall by aprupt stop, beep three times loudly. (that's kind of reaching..)

Once again, some of this might have already been discussed. * Intuitive mute: put the ringing phone on a flat horizontal surface (table) with its screen facing down to stop the ringing. Intuitive for the user and easy to detect with the accelerometers. Could also be used to hang up the current call. The gesture is very distinguishable and is hard to misinterpret because there aren't many situations when the user would normally put the phone on the table screen down. * Vibration control: when the phone is lying flat, either with its screen up or down, don't vibrate, so as to not produce the annoying loud noise. Ring instead, or do something else. Maybe make a weaker vibration, if the vibrator can do that. * Step counter: use the accelerometers to count steps when walking or running. Some people use dedicated devices for that. * GPS power saving: you can't move if you don't accelerate, so don't do power-expensive location detection until acceleration is detected. Once it's detected, start monitoring the location and keep doing it. Stop monitoring once the position stops changing for a while. -- Alexey Feldgendler <[EMAIL PROTECTED]> [ICQ: 115226275] http://feldgendler.livejournal.com _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
