... He provided the following example: When people lose their wide field-of-view (e.g., have tunnel vision due to some neurological disease) they find that they can read and their visual acuity is 20-20; they find, however, that it is hard for them to merely waLk through a doorway because they are lacking a functional flow-field, the lateral and vertical expansion flow-fields, which are directly connected by primitive neurc-path ways to the vestibular system and are coordinated in the foculcus of the cerebellum as shown in some brilliant studies by Jerry Simpson and other neurophysiologists recently; the lateral and vertical expansion flow-fields give us our orientation.

... These caveats notwithstanding, Professor Sheridan agreed that the develcpment of a cognitive theory of presence would be a highly desirable gang. He suggested that "pieces of it are lying arching (e.g., the work of Murray and others in image rotation, etc.~.

... . For instance, when I am working in a force field, and I have active force feedback to my hand, then I am stable -- but I have a poor quantitative perception of the acting forces.
