“…Parallel process in the ISO model interact but are not intertwined, the processes share output but not inner-function. The distinct layers or areas of the wayfinding process are supported throughout recent research on human wayfinding (Goerger, 1998;Darken, 1999;Timpf, et al, 1992;Vinson, 1999; Golledge, 1998). This distinction may not be scientifically exact, but it allows the abstraction of It is important to note that the Chen/Stanney and Goerger (Figure 2.2) models are comparable although not superficially so.…”

DISTRIBUTION / AVAILABILITY STATEMENTApproved for public release; distribution is unlimited. 12b. DISTRIBUTION CODE ABSTRACT (maximum 200 words)Most tasks that are desirable to train in a virtual environment are not tasks that we do alone, but rather are executed collaboratively with one or more team members. Yet little is known about how to construct virtual environment training systems that support collaborative behavior. The purpose of this thesis was to explore methodologies for developing collaborative virtual environments for training. Our approach centered on analyzing task or training specific requirements for the simulation environment. We applied user-centered design techniques to analyze the cognitive processes of collaborative wayfinding to develop interface design guidelines. We utilized the results of our analysis to propose a general model of collaborative wayfinding. This model emphasizes team collaboration and interaction in problem solving and decision-making. We tested the model in the field, using cognitive task analysis methods to study land navigators. This study was intended to validate the use of user-centered design methodologies for the design of collaborative virtual environments. Our findings provide information useful to design, ranging from model enhancement to interface development. We have explored the cognitive aspects of collaborative human wayfinding and design for collaborative virtual environments. Further investigation of design paradigms should include cognitive task analysis and behavioral task analysis. Approved for public release; distribution is unlimited.

“…However, it is important that both the direction giver and direction follower establish a common ground to avoid failure in wayfinding (Weiser and Frank 2013). Furthermore, hierarchy of spatial objects is also evident in wayfinding instructions showing how landmarks and paths are clustered based on its functionality (Taylor and Tversky 1992) as well as street networks (Timpf et al 2005;Tomko et al 2008) which is useful for route planning Steck and Mallot 2000). This is highlighted in the development of the anchor point theory (Golledge and Stimson 1997) emphasizing how reference points anchor known regions in an area that are important in wayfinding.…”

Orientation information in wayfinding instructions: evidences from human verbal and visual instructions

2016

Although the importance of landmarks for human navigation and for orientation is well accepted, most of today's navigation systems hardly incorporate any landmark information or information supporting orientation. Different from previous research that only addressed turn-by-turn instructions in verbal forms and landmarks at decision points, the present study provides empirical evidence that human-generated wayfinding instructions are not solely turn-by-turn but the majority of instructions provide orientation information. We propose a new classification scheme for identifying information in wayfinding instructions that will not only support orientation but also facilitate construction of mental map. We explored and compared two forms of representations-visual sketch map and verbal instructions. Results revealed that landmark information is important in human wayfinding instructions with particular importance of local landmarks along the route and global landmarks that support orientation. In addition, sketch maps contained more global landmarks than verbal instructions. In contrast to turn-by-turn navigation, we found that many instructions in human route descriptions do not always refer to turning actions but to orientation. We conducted interviews with a set of raters on what they consider helpful information in both forms of representations. These results confirmed our findings and supported that future route descriptions can be more meaningful and helpful when they are enriched with orientation information as they conform to how humans structure wayfinding instructions.

“…To make best use of different data sources, e.g., to carry out advanced spatial analysis based on different abstraction levels (Timpf et al, 1992;Lüscher et al, 2009), matching between datasets is needed. On the other hand, to fulfill the increasing and diverse demand of spatial data at various resolutions and scales, detailed spatial databases are being built or under construction via generalization in many countries, from which smaller scale representations can be derived.…”

ABSTRACT:Matching of building polygons with different levels of detail is crucial in the maintenance and quality assessment of multirepresentation databases. Two general problems need to be addressed in the matching process: (1) Which criteria are suitable? (2) How to effectively combine different criteria to make decisions? This paper mainly focuses on the second issue and views data matching as a supervised pattern classification. Several classifiers (i.e. decision trees, Naive Bayes and support vector machines) are evaluated for the matching task. Four criteria (i.e. position, size, shape and orientation) are used to extract information for these classifiers. Evidence shows that these classifiers outperformed the weighted average approach.* Corresponding
