BACKGROUND The subjects in EEG-Brain computer interface (BCI) system experience difficulties when attempting to obtain the consistent performance of the actual movement by motor imagery alone. It is necessary to find the optimal conditions and stimuli combinations that affect the performance factors of the EEG-BCI system to guarantee equipment safety and(More)
Using an instrumented surgical tool, high-precision recordings of hand tremor were taken during vitreoretinal microsurgery in a rabbit model in vivo. The data obtained using a compact, custom six-degree-of-freedom inertial sensing module were filtered and analyzed to characterize the physiological hand tremor of the surgeon. Tremor during the most delicate(More)
