....adequately explored the world. This is particularly true for novice users of a virtual world, who should be helped as much as possible to navigate the world by offering them proper navigation aids (see, e.g. the survey on navigation and wayfinding issues in virtual environments provided by [20]) To this purpose, a first category of solutions can be derived from the design of realworld environments. For example, in the design of buildings, architects aim at reducing wayfinding problems for the people traveling the building by increasing visual access (i.e. the number of parts of the ....

.... can be informally defined as the process whereby people determine where they are, where everything else is, and how to get to particular objects or places [14] Human navigation abilities in the physical world have been studied both in psychology and architecture (a concise survey is provided by [18]) There are two distinct types of navigational knowledge of an environment (that can be generalized and apply to the case of VEs) each one supporting different behaviors. Route knowledge (also called procedural knowledge) is egocentric, describes paths Permission to make digital or hard copies ....

....within the environment) To improve the acquisition of navigational knowledge in VEs, some lessons can be learned from the design of real world environments. For example, in the design of buildings, architects aim at reducing wayfinding problems for the people working or visiting the building [18] by increasing visual access (i.e. the number of parts of the environment which can be seen by a person from her position in space) or including navigational cues (e.g. room numbers, names of buildings, landmarks) Landmarks are distinctive environmental features (e.g. a statue, a river, a ....

....of links or placing additional icons near the links. Adding this supplemental material is just as easy in 3D environments. For example, Satalich designed a system to help guide people through an architectural structure that consisted of drawing lines on the floor that connected points of interest [7]. As described above, the study of interaction with 3D environments has yielded a collection of techniques that can be used to achieve adaptive support for navigation. However, each of these approaches is unique, requiring a separate implementation. In the next section, a framework is proposed ....

There has been considerable research in training environments (for navigation training in particular. Satalich s Master s thesis [Satalich, 1995] provides excellent background on navigation and wayfinding research. Satalich quotes Gluck, Gluck, 1990] defined wayfinding as the process used to orient and navigate. The overall goal of wayfinding is to accurately relocate from one place to another in a large scale space. In addition, ....

.... more rapidly than those who use You Are Here maps, presumably because the time saved going to the destination is less than the time required to read the map (Butler et al. 1993) Signs and markings on the ground have also shown to be an effective way of guiding search in virtual buildings (Satalich, 1995) and large virtual spaces (Darken Sibert, 1996) A wayfinder can lay down cues during a traverse, and then use those cues to backtrack to a previously visited location. While tracking is often an efficient way of getting to a location it has several disadvantages. The wayfinder learns nothing ....

This anecdotal report was documented, in a very different environment, in a Master s Thesis completed at the University of Washington s Human Interface Technology laboratory (Satalich, 1995). The environment to be explored was a virtual building, i.e. a building that existed as interior design plans in a computer. Participants in the study saw computer controlled projections of the views that they would have seen had they been at a particular point and bearing inside the ....

....KEYWORDS: 3D thumbnails, wayfinding, VRML, virtual reality. INTRODUCTION Wayfinding is the ability to find a way to a particular location in an expedient manner and to recognize the destination when reached [13] Travelers find their way using survey, procedural, and landmark knowledge [5, 13, 14, 9]. Each type of knowledge helps the traveler construct a cognitive map of a region and thereafter navigate using that map [10, 11] Survey knowledge provides a map like, bird s eye view of a region and contains spatial information including locations, orientations, and sizes of regional features. ....

Two studies by Darken and Silbert support this adaptation ( 21] 22] but a study by Satalich argues against it [70]. Darken and Silbert investigated the problem of VR users maintaining knowledge of locational information, that is, current position and orientation [21] In addressing this problem, the authors propose a basic taxonomy of virtual worlds. Virtual worlds have three primary attributes size, ....
