In this paper we discuss a method for modelling and generating adaptive navigation sequences from the UML state diagrams. The method is discussed on a case of adaptive e-course.  ...  a prototyping of navigation support in adaptive web-based systems.  ...  There are two possibilities of mappings from information model: (1) a superstate mapped to a class with substates mapped to class attributes, and (2) a superstate mapped to a class instance with substates  ...

Development of User Feedback-Based Optimized Encoding System for 3D-Printed Tactile Maps

Howard Kaplan, Anna Pyayt
2022 Disabilities  
Additionally, users identified a set of important physical objects to be encoded on the map. After that, multiple encodings were evaluated individually and when integrated in maps.  ...  In this study, we worked with fifteen individuals with blindness to develop an optimized encoding system for 3D-printed tactile maps for building interiors.  ...  Different generations of symbols are labeled from a (#1) to e (#5), and for each generation symbols were evaluated in isolation (I) and in combination with other symbols on the map (C).  ...

Semiotic evaluation of Lithuania military air navigation charts

Donatas Ovodas, Algimantas Česnulevičius
2014 Geodesy and Cartography  
The aim of semantic analysis was to determine how the conventional cartographical symbols, used in air navigation charts, correspond with carto-linguistic and carto-semiotic requirements.  ...  Graphical load of maps evaluated of aeronautical maps is not great (5 - 12%) and does not require reduction the information load and generalization of charts.  ...  Acknowledgements The authors are thankful to the Ministry of National Defence Republic of Lithuania for support of the investigation carried out with Lithuanian Air Force staff and article reviewer, whose  ...

Ben Talbot, Obadiah Lam, Ruth Schulz, Feras Dayoub, Ben Upcroft, Gordon Wyeth
2016 2016 IEEE International Conference on Robotics and Automation (ICRA)  
The robot intelligently organises a symbolic language description of the unseen environment and "imagines" a representative map, called the abstract map.  ...  This paper shows that by using only symbolic language phrases, a mobile robot can purposefully navigate to specified rooms in previously unexplored environments.  ...  Some progress has been made in this area, with a number of robotic systems developed to use symbolic spatial information to guide navigation, including gestures [3] , maps [4] , 1 The authors are with  ...

Cognitive instruction interface for mobile robot navigation

Mohammed Elmogy, Christopher Habel, Jianwei Zhang
2009 2009 International Conference on Computer Engineering & Systems  
In our system, the instructions of the processed route are analyzed to generate a symbolic representation of the navigation task via the instruction interpreter.  ...  The resulting symbolic representation is used to generate a graphical representation of the route to supply the robot with the information about the route's environment and the relationships between the  ...  The generated symbolic representation is used to create a topological map for the route environment.  ...
