In dataset1, nine FSR strips were located in the socket so that it was covered by sensors as much as the physical shape of the socket allowed as shown in Figure 2. Figure 2. For dataset2, four strips were located on the extensor and flexor muscles to cover the muscle bellies.
The six grips used in this protocol: (A) relax, (B) open, (C) force, (D) tripod, (E) finger point, (F) key.
