The effects of limb position and grasped load on hand gesture classification using electromyography, force myography, and their combination
Fig 2
The reaching positions, standing zones, and hand gestures.
(a) The reaching positions and standing zones for the experiment [42]. The subject would reach to positions 1-4 while standing at zone A and positions 5-8 while standing at zone B. The participant’s elbow was bent at 90 degrees at position 2, between 90 degrees and fully extended for positions 1, 3, and 4, and fully extended for positions 5-8. (b) The 4 hand gestures used for the experiment along with the 3D printed manipulandum. The manipulandum was made of two parts which allowed it to be top loaded and grasped with a variety of hand gestures. The weights used for the experiment consisted of a no weight condition (the weight of the manipulandum, 53 g), 250g, 500g, 750g, and 1000g.
