Read more on how the project is going here. I will release a video on YouTube that will demo the gesture recognition framework at the end of June. I'm currently working on continuous recognition. I've already done isolated recognition. Continuous recognition is almost like isolated recognition, only that I'm using a two-class gaussian classifier as the end-point detector.
Applications (needs some cleaning)
- Mute audio or suspend when screen is facing down;
- Go to main menu when shaken;
- Volume up/down during call when tilting left/right (still unclear);
- Turning the phone face to the user (not the same as taking it to the
ear) to turn on the backlight
- Automatic portrait/landscape switching for the UI
- Turning the phone screen down to mute sound (and probably turn off the
backlight) or hold call
- Swinging in an O-shape in the air to redial
- Moving the phone in a firm gesture from one ear to the other to switch
between active and held calls
- Scrolling with firm tilts (suggested several times, should see if it's
- Dropping (suggested several times, though it's unclear how to react to
- Shaking to get audio feedback (could e.g. imitate balls rolling inside
to the number of unread messages, or liquid splashing to incdicate the battery level)
- Starting driving in a car (if that's detectable -- probably has other
patterns than walking etc) to switch to some “car mode”
- Stopping e.g. at a traffic light to choose a better time to notify about
new messages than while driving
- Taking off in a plane (should be detectable, but hard to train) to shut
down all RF systems
- Similarly, landing to re-enable RF systems
Vigorous shaking (side to side) while receiving a call could reject it.
A sideways swing (90degres) out of the wrist could mean general Cancel/Esc/Back A long swing could close a app (more a arm swing than wrist. Same G-forces but longer time). These swing moves could be used on two axis and each in two axis for different usage. A firm wrist tilt backside down could mean global OK.
Maybe some basic moves like thsese should have absolute global meaning.
(like left, right, enter, esc)
Mute phone my hitting it on something hard three times with one side.
Face down lying still - lock screen Face up lying still - never lock screen
- holding the moko out & angling the front of it up repeatedly turns up
- angling front down repeatedly turns down volume
- a set of 5 or 10 standard, easily distinguishable gestures that the user
can map to favorite programs
