Abstract

Pictures are tactile as well as visual. Outline pictures stand for the same kinds of surface features in touch and vision. Vantage point geometry is used by blind and sighted perceivers in pictures. Limits of pictures may be comparable for the blind and sighted, and transcended in useful ways. Introduction In keeping with a conference on the multimodality of human communication, the purpose of this paper is to show that some aspects of pictures are tangible as well as visual. Many means of communication are often considered to be exclusively visual or auditory, but the exclusionary view requires radical revision, the evidence from pictures tells us.
