Abstract: Physiologic hand Tremor is a common trait among humans although it varies in amplitude and frequency from individuals to individuals. It is generally unnoticeable as its amplitude is small. The amplitude of hand tremor can worsen due to anxiety, fatigue or use of stimulants like caffeine. However, it is a big factor limiting the effectiveness of microsurgery performed by microsurgeons. Microsurgery is usually performed under the microscope and gave the surgeons no force feedback. A steady hand that moves with high precision is desired for microsurgery. Instruments to compensate for hand tremor have been developed to reduce the tremor and improve the precision of microsurgeons. To effectively compensate for the tremor, a highly accurate tremor measuring device is needed. Thus, an optical based Micro Motion Sensing System (M2S2) has been invented by a graduate student. However, over the years, its performance has deteriorated. This study has been conducted to find out ways to improve the performance of M2S2. In addition, M2S2 is only able to measure 3 dimensional position data. The study also works on devising a new system to capture in total 6 degrees of freedom motion data (3 dimensional position data + Pitch, Yaw & Rotation). The two objectives of the study have been met within the scopes specified.
