Functional Scales in Assisted Wayfinding (Short Paper)

Authors: Heinrich Löwen, Jakub Krukar, and Angela Schwering

Published in: LIPIcs, Volume 142, 14th International Conference on Spatial Information Theory (COSIT 2019)


Abstract
GPS-based navigation systems are widely used to get wayfinding assistance. Current navigation systems incorporate different map scales for presenting wayfinding instructions, however, the selection of scale is not supported by psychological findings. Different tasks of the users such as the identification of the next decision point or the orientation within the environment might be supported best at particular scales. We propose a new conceptual distinction of functional scales with respect to their role in supporting wayfinding and orientation. We suggest that these functional scales can have a benefit for supporting wayfinding and orientation if used for providing wayfinding instructions. This we aim to empirically evaluate in future work.

Rule-based Model Extraction from Source Code

Authors: Rui Correia, Carlos Matos, Mohammad El-Ramly, and Reiko Heckel

Published in: Dagstuhl Seminar Proceedings, Volume 6302, Aspects For Legacy Applications (2007)


Abstract
In the context of an approach for reengineering legacy soft- ware systems at the architectural level, we present in this paper a reverse engineering methodology that uses a model de¯ned as a type graph to represent source-code subject to a code categorization process. Two al- ternative methods for referencing the source code are discussed: native vs. graphical. To represent the code, the native representation uses the abstract syntax tree while the graphical uses a programming language metamodel. Two options regarding the way that the graph can relate to the source code reference model are also considered: association model vs. direct link. The extraction of the program representation, complying to the type graph, is based on rules that categorize source code according to its purpose. The techniques to address this process, such as the code categorization rules, are shown together with examples.
