(A) Prosthetic emulator set-up for trigger control with dual-site electrodes (top) and pattern recognition with eight pairs of dome-shaped electrodes (bottom). The prosthesis was attached to the emulator socket such that it was below the right anatomical limb when the forearm was in a neutral position in front of the body. There was a 2-cm lateral gap between the emulator socket and the prosthesis using two bolts to allow movement of the anatomical right hand, which was necessary to control the prosthesis. (B) Set up of the Coffee Task. Participants interacted with the task objects that were placed in their designated area on the placemat. The height of the table with the placemat was aligned with their greater trochanter. (C) Individual segments of the Coffee Task. Participants were asked to complete the task both continuously and in segments
