... 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.

Hale, Joseph P. and Dittmar, Mary Lynne (1994): Virtual Reality as a Human Factors Design Analysis Tool for Architectural Spaces -- Control Rooms to Space Stations I: Objective Measures. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 275-279.

One class of Virtual Reality (VR) applications is as a Human Factors design analysis tool for work areas and other architectural spaces. A study was conducted to compare subjects' qualitative and quantitative judgments of two "real" world control rooms at the Marshall Space Flight Center (MSFC) and their corresponding virtual counterparts. The overall Independent Variables (IVs) were World (Real/Virtual) and Room (PCR/SIM) with Gender and World Order (Virtual-Real/Real-Virtual) as blocking variables. Nested within Room were range and relative range estimations. Range estimations were comprised of two IVs: 1) Item (Object/Surface) and 2) the Item's Range from the observer (Near/Far). The relative range estimations were comprised of two IVs: 1) Field-of-View (FOV) (Same/Different, i.e., whether or not the subject can see both objects simultaneously in the same FOV) and 2) the objects' Distance from the observer (Close/Away). There appears little difference between real and virtual worlds in one's ability to differentiate and estimate gross distances and to discriminate small relative range differentials within the same FOV. For different FOVs, this discrimination ability starts to deteriorate in the real world and is lost in the virtual world. There is also a clear World main effect of increased time to make judgments in the virtual world. The different perceptions, and the longer response times, point to a level of filtering occurring in the virtual environment that must be carefully considered when deciding where and how to use VR as a Human Factors analytical tool.

Dittmar, Mary Lynne and Hale, Joseph P. (1994): Virtual Reality as a Human Factors Design Analysis Tool for Architectural Spaces -- Control Rooms to Space Stations II: Subjective Measures. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 280-284.

The Architectural Space Questionnaire (ASQ) was developed and employed in order to assess subjects' impressions of four different environments (two real and two virtual rooms) at the NASA Marshall Space Flight Center. The ASQ consists of 18 adjective pairs, arrayed in a 7-point, Likert scale format. Subjects first participated in a variety of distance estimation tasks in the Spacelab Payload Control Room and the Simulation Control Room and in their virtual reality (VR) analogs. After their experience in each room, subjects responded to the ASQ, selecting one value on each adjective pair continuum which best described their impression of the room they were in. The results indicated that the ASQ is sensitive to structural differences between real rooms. Differences between virtual rooms were minimal, possibly due to the absence of visual cues such as lighting and texture in that environment. Implications for the use of VR as a design tool are explored.
