Tangible pictures: viewpoint effects and linear perspective in visually impaired people.

abstract：:A fundamental issue in the study of human vision is the accuracy with which observers can perceive the three-dimensional structures of objects in the environment. The formal mapping from physical to perceived space is considered as a geometric transformation, and the literature is reviewed to identify which aspects of...

The specific objective was to test whether the relative intensity and location of a seemingly irrelevant visual stimulus would influence auditory lo...

However, it has been previously noted that, if the gratings are briefly flashed, they will appear to fuse into a plaid or checkerboard ...
