For the orientation issue while pointing outward and tracing half circles: i think it’s the magnetometer. I have an old and new ps move that behaves differently. However, when it can’t see the bulb properly, it either jumps up, or move to the body. There is a need to handle that error (when the bulb is obscured or when it’s outside of sensor fov/range) because it does crash the game. The best color i found for calibration was magenta and blue with darkness filter in a low lit room.
Having the kinect360 at 45deg downward at 2.5m height lessen occlusion but bulb tracking is still a bit jerky at long range. Especially when I go beyond 180 because backward is further away from the sensor.
