Idea how to expire gesture steps - in pseudo-pseudo C#/Java code

gistfile1.cs

// Member objects
mTimerTask = new Task(){
    mIsTrackingGesture = false;
};
mIsTrackingGesture = false;

// In the frame_ready

mGestureDetector.detectBeginGesture();

if (mGestureDetector.beginningDetected() )
{
    // Detected a possible gesture
    somehowSetIsTrackIngToTrue();
    // Start counting down the expiration
    TaskSchedule aSchedule = new TaskSchedule();
    aSchedule.registerTask(mTimerTask, inDelaySeconds);

    if( mGestureDetector.detectMidGesture() && mIsTrackingGesture ) {
        // Cancel the expiration
        aSchedule.cancelTask(mTimerTask);
        // Register the expiration again until next gesture key is
        // reached
        aSchedule.registerTask(mTimerTask, inDelaySeconds);

        if( mGestureDetector.detectEndGesture() && mIsTrackingGesture ){
            // Gesture detected !! You win
            doSomething()

            // Clean-up back to normal state
            aSchedule.removeAllTask();
            mIsTrackingGesture = false;
        }
    }
}
