Format of the marker position data (*.csv files):

	First a header with metadata, then in each line comma-separated values
	containing frame index and three positional values (X,Y,Z) for each marker

Types of tracked hand motions:

	General Movements: general hand movements that cover large parts of the
	hand's natural degrees of freedom

		Trial 01: flexion of all fingers simultaneously / closing hand
		Trial 02: abduction / splaying out the fingers
		Trial 03: touching the thumb with every finger
		Trial 04: flexion of the fingers (open -> closed)
		Trial 05: flexion of the fingers (closed -> open)
		Trial 07: miscellaneous movements and gestures
		Trial 08: miscellaneous movements and gestures

	Interaction: movements with object interactions -- grasping motions (power
	grasps, precision grasps), other interaction movements (handling of pens,
	jar lids, paper, smartphone)

		Trial 01: closing a big jar (large twist motion)
		Trial 02: closing a small jar (small twist motion)
		Trial 03: grasp movements (precision grasp und power grasp)
		Trial 04: grasp movements with a small object (power grasp)
		Trial 05: grasp movements with a small object (precision/power grasp)
		Trial 06: grasping and holding of a pen (precision grasp)
		Trial 07: interaction with a smartphone
		Trial 08: folding a piece of paper, flattening with one finger
		Trial 09: folding a piece of paper, flattening with all fingers

	Sign Language: various sybmols from the American Sign Language Alphabet

		Trial 02: N/A
		Trial 03: N/A
		Trial 04: N/A
