Comparison between the new automatic training method and the previous training method

	New Automatic Training	Traditional Training
Connection to external device	A laser distance sensor and an IMU are required, which are both portable, and can be integrated into the prosthesis system in the future	An external computer is required.
Requirement of extra manpower	No.	A professional experimenter is required.
Total training time	30 s calibration time for measuring a few parameters; 225 s for performing movement tasks; 0.11 s for the rest training process;	225 s for performing movement tasks; 24 s for offline processing of training algorithm; At least 10 minutes for interacting with the experimenter, and manual data labeling
Is the system easy to follow?	User-driven: The training can be easily operated by a 'naïve user' unaided. The user only needs to perform all the movement tasks, and the training will be immediately done.	Experimenter driven: The user needs to follow the guidance from the experimenter. The user needs to pause and wait when the experimenter is processing the data.
The way to switch the prosthesis control mode	Automatic switch; Driven by user's motion	Manual switch; Controlled by experimenter
