Near-by - Implement throw gesture

[jkrumow]

• see throw gesture implementation in https://github.com/hoccer/android-hoccer-client
• try to reuse the Hoccer Classic code

See evaluation on iOS side #102, if helpful.

Checked out Android client implementation and found what is necessary:

package com.hoccer.android.gesture;

• MotionInterpreter
• MotionGestureListener
• Detector, ThrowDetector
• FeatureHistory, FeaturePattern, LineFeature
• Gestures

Dependencies:

The android client uses toxic library 2D and 3D vectors. But they can be replaced.

• toxi.geom.Vec2D
• toxi.geom.Vec3D

Looks similar to iOS implementation.

Next steps:

• SensorManager API has been updated
• Use replacement for toxic.geom.Vec2D and toxic.geom.Vec3D

[jkrumow]

Corrected usage of deprecated APIs. Added replacement for Vec2D and Vec3D classes.

Motion detection works.

How to use it:

// implement MotionGestureListener interface
@Override
public void onMotionGesture(int pType) {
    String gestureName = Gestures.GESTURE_NAMES.get(pType);
    LOG.debug("Received gesture of type: " + gestureName);
}
// instantiate MotionInterpreter with gesture type, context and MotionGestureListener
// for gesture type you can choose:
// SHARE = throw detection
// RECEIVE = catch detection
// SHARE_AND_RECEIVE = throw and catch detection
mMotionInterpreter = new MotionInterpreter(Gestures.Transaction.SHARE, this, myMotionGestureListener);
// activate the MotionInterpreter when you want to receive gesture events
mMotionInterpreter.activate();

Is it already coupled to the send button in ChatView? If so make a test apk and upload it to Hockey APP for the testers

[jkrumow]

Didn't know this was part of the task. But no problem, I can do that tomorrow.

ok I will put it on the test sheet for the next version!
