From: A compact solution for vibrotactile proprioceptive feedback of wrist rotation and hand aperture
The results obtained by 4 amputee participants using Compact and Conventional feedback. Left panels show the performance for each block of trials, to assess the potential learning effect, while the right panels represent the average across blocks. HA indicates aperture, and WR represents wrist rotation. Different colours are associated to different participants (P1-P4). The horizontal dashed lines in the right pannels indicate the mean performance of able-bodied subjects. Bn in the left plots denote different testing blocks
