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 …

Haptic Perception Of The Horizontal By Blind And Low-Vision Individuals, Morton Heller, Deneen Brackett, Eric Scroggs, Angela Allen, Shavonda Green
Haptic Perception Of The Horizontal By Blind And Low-Vision Individuals, Morton Heller, Deneen Brackett, Eric Scroggs, Angela Allen, Shavonda Green
Faculty Research and Creative Activity
We examined haptic perception of the horizontal in visually impaired people. Blind people (late blind and congenitally blind), persons with very low vision, and blindfolded sighted individ- uals felt raised-line drawings of jars at four angles. They had to demonstrate their understanding that water remains horizontal, despite jar tilt, by selecting the correct raised-line drawing given four choices. Low-vision subjects, with near perfect scores, performed significantly better than the other groups of subjects. While the late-blind and blindfolded sighted subjects performed slightly better than the congenitally blind participants, the difference between the late-blind and congenitally blind groups was nonsignificant. The …
