Alpha 2 Release (14 Aug 2008) for Neo FreeRunner
Remark: Please watch the video, so that you'd know what to expect out of the Alpha 2 Release.
Alpha 2 Release: The Quick Way
SSH Neo FreeRunner:
wget http://accelges.googlecode.com/files/accelges_0.1.0-svnr204-r2_armv4t.ipk opkg install accelges_0.1.0-svnr204-r2_armv4t.ipk
On The Neo FreeRunner
Over SSH you must use
DISPLAY=:0 /etc/init.d/gesl start
(otherwise screen orientation won't work):
You're ready: make a gesture, make Neo change its screen orientation (if you did watch the video, you'll know what to do).
Training: The Quick Way
OPTIONAL: Stop the gesture recognizer, and listener:
/etc/init.d/gesd-neo2 stop /etc/init.d/gesl stop
Home > Gestures
Select a gesture, press Train, and follow instructions.
REQUIRED: Start/restart the gesture recognizer, and listener:
/etc/init.d/gesd-neo2 start (from SSH, or from Neo) /etc/init.d/gesl start (only from Neo)
Alpha 2 Release Details
- You can use any distribution you like; I would suggest using the Om 2008.8 for now. You'll need these dependencies:
dbus, dbus-glib, libxrandr, libnotify, notification-daemon, libcurl, and gtk+
- On the Om 2008.8, you'll be missing:
libnotify, notification-daemon, libsexy2, libwnck-1-18, libstartup-notification-1-0, and libglade-2
opkg install libnotify notification-daemon libsexy2 libwnck-1-18 libstartup-notification-1-0 libglade-2.0-0
Remark: On the 2008.8, your missing dependencies will be downloaded automatically by the installer.
Preparing Om 2008.8 for Gestures
- Turn off Suspend:
Home > Settings > Suspend > off
- Make sure Neo has Web Access (use SSH):
echo "nameserver xxx.xxx.xxx.xxx" > /etc/resolv.conf
- Install Terminal:
Home > Installer > Development > openmoko-terminal2
- Create a shell script that will start the gesture listener daemon (use SSH):
echo "exec /etc/init.d/gesl start" > /usr/bin/gesl-begin chmod +x /usr/bin/gesl-begin
- Restart Neo!
- Download the Alpha 2 Release Package, or (use SSH):
echo "nameserver xxx.xxx.xxx.xxx" > /etc/resolv.conf wget http://accelges.googlecode.com/files/accelges_0.1.0-svnr204-r2_armv4t.ipk
opkg install accelges_0.1.0-svnr204-r2_armv4t.ipk
- Launch the Gesture Manager:
Home > Gestures
- Select a gesture and click the first icon on the toolbar; Follow the instructions. Do the same for all the gestures!
- Step 1: Launch Gesture Manager
- Step 2: This is the Gesture Manager
- Step 3: Select a gesture, and click Train (first icon from the toolbar)
- Step 4: Make the gesture (this step creates the gesture)
- Step 5: Make the gesture again (this step trains the gesture)
- Step 6: Select another gesture, and do the same
- Step 1: Launch Gesture Manager
- Restart the Gesture Recognizer (use SSH):
Remark: You have to restart the Gesture Recognizer, so that it will re-read the newly trained gestures. Every time you train one or more gestures, restart the recognizer!
- Use the script you have created before; be sure to run the script from the Neo, no SSH or VNC:
- There are 12 gestures available (once, you make one, a notification will pop up):
||Z gesture: |
||Down gesture: |
||Down-up gesture: |
Remark: If you don't start the Gesture Listener from the Neo, screen orientation won't work
How To Improve Recognition Accuracy
- Check to see which gesture gets recognized most often. Try training those gestures again.
- Determine which gestures don't get recognized at all. Try training those gestures again.
Alpha 2 Development Details
Gesture Recognizer (gesd) sends signals on:
org.openmoko.accelges /org/openmoko/accelges/Recognizer org.openmoko.accelges.Recognizer.Recognized
Try (on FSO distribution)
mdbus -s -l
and make a gesture for more information on DBUS.
The configuration file for Neo is:
# Paul-Valentin Borza <email@example.com> # gestures configuration file for Neo/Wii # classes and probabilities for classifier # sclass\tFILE static acceleration class # dclass\tFILE dynamic acceleration class # sclassp\tVALUE probability for static acceleration class # dclassp\tVALUE probability for dynamic acceleration class sclass s.class dclass d.class sclassp 0.4 dclassp 0.6 # classes for recognizer (add more than one) # class\tid\tFILE static acceleration class class screen_zzp screen_zzp.class class screen_zzn screen_zzn.class class screen_zpz screen_zpz.class class screen_znz screen_znz.class class screen_pzz screen_pzz.class class screen_nzz screen_nzz.class class screen_npp screen_npp.class class screen_nnp screen_nnp.class class screen_pnp screen_pnp.class class screen_ppp screen_ppp.class # models for recognizer (add more than one) # model\tid\tFILE dynamic acceleration model model left left.model model left, and return left-and-right.model model right right.model model right, and return right-and-left.model model up up.model model up, and return up-and-down.model model down down.model model down, and return down-and-up.model model shake, shake shake-shake.model model horizontal circle horizontal-circle.model model forward, backward forward-backward.model model z z.model
Again, if you modify the configuration file, you'll have to restart the gesture recognizer (gesd).
Gesture Recognizer that uses the top accelerometer (/dev/input/event2):
Gesture Listener that switches screen orientation, and notifies the user of recognized gestures on the screen:
Remark: Start the recognizer first, and after that the listener (obvious, but important)
Try playing with:
gesd (gesture recognizer) gesl (gesture listener) gesm (gesture manager)
- One, or both accelerometers might not work. Try:
hexdump /dev/input/event2 (for top accelerometer) hexdump /dev/input/event3 (for bottom accelerometer)
Remark: The Alpha 2 Release uses the TOP accelerometer
- After a while, the accelerometers might stop working.
Restart your Neo!
- After a while, the accelerometer send bogus values (values that are lower than what they should be). If this happens, the classifier won't be able to classify dynamic/static acceleration, and nothing will work - nor the gesture training, nor the gesture recognition.
Restart your Neo!
- Mute audio or suspend when screen is facing down; - NO SUPPORT FOR MUTE/UNMUTE AUDIO IN NEO FOR NOW
- Go to main menu when shaken; - NO SUPPORT YET
- Volume up/down during call when tilting left/right (still unclear); - NO SUPPORT YET
- Turning the phone face to the user (not the same as taking it to the ear) to turn on the backlight - BACKLIGHT HAS A BUG, CAN'T BE USED YET
- Automatic portrait/landscape switching for the UI - Done
- 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 usable)
- Dropping (suggested several times, though it's unclear how to react to it)
- 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
- This is a bad idea - you need to do that way before it lifts off the ground
- Similarly, landing to re-enable RF systems
- Similarly, you shouldn't turn them back on until way after the wheels touch the tarmac
- 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 these 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 volume
- 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
