Figure Legend: From: Eidolons: Novel stimuli for vision research Journal of Vision. 2017;17(2):7. doi:10.1167/17.2.7 Figure Legend: Renderings of possible stimuli for a haptic perception experiment. Notice that we simply mapped image intensity in the eidolon image to relief height. One could 3D print the central stimulus, have observers explore it by touch, and have the observers navigate the parametric space of rendered eidolon shapes until they find a perceptual match. We can expect that observers will tend to regularize the haptic percept, thus preferring a lower value of reach, but we are agnostic about what they will do with coherence.
