FeetBack system on the user and its components. FeetBack system remaps the foot rolling sensation under the user’s feet (lateralized feedback on the stance) onto the skin of the back. It includes two main parts: a wearable gait measurement system and a torso-worn vibrotactile display. The wearable gait measurement system detects the user’s step. It consists of pressure-sensitive insoles under the user’s feet, two ankle boxes, and the main control board attached to the participants’ lower back. The two force-sensitive sensors that are located at the heel (specified with dashed circles) were used to detect heel-strike. The vibrotactile display provides moving sensations (i.e., VAM) on the participant’s back and includes two vertical vibrator arrays attached to foam, a torso-worn vest, and the controller board. Feedback on the stance was provided from down to up (solid black arrows)
