The Influence Of Viewpoint And Object Detail In Blind People When Matching Pictures To Complex Objects, Morton A. Heller, Tara Riddle, Erin Fulkerson, Lindsay Wemple, Anne Mcclure Walk, Stephanie Guthrie, Crystal Kranz, Patricia Klaus
Faculty Research and Creative Activity
We examined haptic viewpoint effects in blindfolded-sighted (BS) and visually impaired subjects: early blind (EB), late blind (LB), and very low vision (VLV). Participants felt complex objects and matched tangible pictures to them. In experiment 1, the EB and BS subjects had similar overall performance. Experiment 2 showed that the presence of a detail on the target object lowered performance in the BS subjects, and that matching accuracy was lower overall for top views for the blind subjects. In experiments 3 ^ 5, EB, LB, VLV, and BS subjects made judgments about perspective pictures of a model house with more …
