Fig. 1: Specific examples of price to walk curves for different conditions.
From: The economic value of augmentative exoskeletons and their assistance
a Representative price to walk curves for the walking-no-exo condition (teal) and the exo-powered condition (purple) from different subjects. The marginal value (MV, the value of the exoskeleton assistance) is given by the area between the curves. In actual trials, the price to walk curves are estimated by fitting first-order exponentials to subject bids. Circles denote winning bids, while squares denote losing bids. The participant in (b) shows a clear benefit from the device, the one in (c) shows a clear detriment, and the one in (d) is more ambiguous.
