....the virtual environment is usability. Much has been written on usability of the user interface of interactive applications (especially of GUI) but there is little research on usability in VEs. Even the methods applied to interactive applications are not suitable and rather limited for VEs [5]. There has been some research done on wayfinding in large virtual worlds. This is important, because badly designed (large) virtual environments create problems as to wayfinding in virtual worlds. For example, one of the problems can be that they have di#culty to relocate places where they have ....

After some contemplation, the list of applications (of length zero) was sufficiently convincing that I was able to put away my charge card (with the inevitable ensuing dejection) Clearly, there is some mediation effect that the control display device exerts on the utility of the bandwidth [1]. Device Capability Have you read this far only to be told that what s important is what devices you can lay your hands on Everyone knows that. No. In fact, obtaining access to the right devices isn t enough, in one obvious way, and another not so obvious. The obvious way, of course, is ....

Wayfinding is obviously not the only task a user may want to do when navigating in virtual spaces [5]. In complement to be as free as a bird , which should be always possible, Figure 1.

Hix et al. illustrated in depth, user centered design for a specific application [11] We have adopted their overall approach of using expert heuristic evaluation followed by formative user evaluations; however, we needed to adapt some aspects for our purposes, ....

An exhaustive analysis of usability characteristics, including navigation methods, has been undertaken in a report by Gabbard and Hix [8]. Very recent work includes, for example, user studies showing the advantage of a hierarchy of usability methods in virtual reality by Hix, et al. 14] who conclude that navigation . inavirtualworld . profoundly affects all other user tasks. They also compare exocentric viewing to ....

....paradigm. Due to the innovative and complex nature of VEs, it is not presently clear that limiting VE development to standardized interaction styles is even desirable. In fact, most research on VE interaction methods focuses on categorizing specific styles for use in specific tasks [Bowman98][Gabbard97] [Kaur97] This lack of conformity in interaction style combined with the continual introduction of new I O devices places more responsibility on VE application developers. We believe that early incorporation of usability assessments into the user interface design process will ensure that the ....
