Signal Jitter is an impediment that continues to affect many technologies. Its presence in optical tracking devices is manifested in tracking data and affects the device's accuracy and latency. Previous studies have investigated several smoothing techniques to reduce jitter, while accounting for engine vibration as an external source. This paper will delve further into the research by exploring the characteristic behavior of the optical tracking data, so that a more intuitive selection of a smoother can be made. This process will not only justify the suitability of a smoothing technique for SVS, but also lead to increased tracking efficiency.
