看看这个图片，有人用脚开飞机，用几个踏板去控制，在游戏中，开飞机的操作比较简单，上升，下降，加减油门，方向左，方向右。

 android设备中，使用模拟点击就可以实现这个功能，在操作踏板的时候发送对应的touch事件，具体可以参考frameworks/base/cmds/input/src/com/android/commands/input/Input.java

209    private void sendTap(int inputSource, float x, float y) {
210        long now = SystemClock.uptimeMillis();
211        injectMotionEvent(inputSource, MotionEvent.ACTION_DOWN, now, x, y, 1.0f);
212        injectMotionEvent(inputSource, MotionEvent.ACTION_UP, now, x, y, 0.0f);
213    }


298    private void injectMotionEvent(int inputSource, int action, long when, float x, float y, float pressure) {
299        final float DEFAULT_SIZE = 1.0f;
300        final int DEFAULT_META_STATE = 0;
301        final float DEFAULT_PRECISION_X = 1.0f;
302        final float DEFAULT_PRECISION_Y = 1.0f;
303        final int DEFAULT_EDGE_FLAGS = 0;
304        MotionEvent event = MotionEvent.obtain(when, when, action, x, y, pressure, DEFAULT_SIZE,
305                DEFAULT_META_STATE, DEFAULT_PRECISION_X, DEFAULT_PRECISION_Y,
306                getInputDeviceId(inputSource), DEFAULT_EDGE_FLAGS);
307        event.setSource(inputSource);
308        Log.i(TAG, "injectMotionEvent: " + event);
309        InputManager.getInstance().injectInputEvent(event,
310                InputManager.INJECT_INPUT_EVENT_MODE_WAIT_FOR_FINISH);
311    }
