A Schematic of the experimental setup with the participant playing a visual feedback balance exercise, while Kinect v2 depth camera and pressure mat information are simultaneously collected. B Schematic of visual feedback training exercises used in the current FES + VFBT system [11]. The red cursor represents the participant’s COP. The participants played through three sets of four VFBT exercises. Within each set, the order of the exercises (e.g., hunting, color matching, etc.) were randomized
