“ ... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested. ”

-- Steve Krug, Don't Make Me Think, p. 136

Bocker, Martin, Runde, Detlef and Muhlbach, Lothar (1995): On the Reproduction of Motion Parallax in Videocommunications. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 198-202.

“The paper addresses the question whether reproducing motion parallax increases the extent of telepresence in videocommunications. Motion parallax is defined as the change of the view due to the observer's movements. It was hypothesized that reproducing motion parallax (a) leads to more precise depth judgments by providing further depth cues, (b) allows 'interactive viewing', i.e. the observer can actively explore the visual scene by changing his/her position, and (c) compensates for stereoscopic "apparent movements". In a Human Factors study, two videoconferencing set-ups providing motion parallax (one stereoscopic and one monoscopic version) were compared with two set-ups (monoscopic and stereoscopic) without motion parallax. Each set-up was used and rated by 32 subjects. The results supported the hypotheses only in part. Even though there was some evidence for more "spatial presence" and for a greater explorability of the scene through motion parallax, the compensation of apparent movements could not be achieved.”

Runde, Detlef and Bocker, Martin (1994): Stereoscopic Telepointing in Videocommunications. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 185-189.

“Stereoscopic telepointing to be employed inter alia in cooperative telework applications yields many benefits but also poses a number of problems addressed in a study with 96 subjects under four different conditions. For two conditions, 3D-input devices were designed implementing different input metaphors. The 'Light Beam Metaphor' is analogous to pointing to objects with a slide show pointer or laser pointer. The 'Reference Space Metaphor' provides the users with the possibility of pointing to details of an object in such a way as if a re-sized model of the object was present in front of them and within reach of their hands. The other two conditions were stereoscopic and monoscopic control conditions without pointers. The subjects' task was to identify differences between a remote and a local object within a limited time. The results show that the Light Beam Metaphor pointer was easier to handle and conformed to a larger degree to the users' expectations, whereas the Reference Space Metaphor pointer received better subjective ratings on efficiency and Telepresence. The analysis of the results of all four conditions established the benefits of 3D over 2D representations for object-oriented communicative situations in terms of appeal and the impression of depth.”
