Wei Shi, Randy Goebel, Tanaka Yuzuru, A new database visualization framework for the automatic construction of non-standard charts: Re-creating the chart of Napoleon's Russian Campaign of 1812, Cartographica, 10.3138/carto.49.4.2487, 49, 4, 241-261, 2014.12, In the last decade, research on database visualization has made great progress in automatically constructing charts composed of standard primitive charts. The next research challenge is to automatically construct non-standard charts which cannot be simply composed with standard primitive types of charts. One typical example is the chart of Napoleon's Russian campaign of 1812. As to the challenge of automatic construction of such complex charts, we may classify conventional visualization frameworks into two categories. The first category asks users to procedurally define non-standard charts by programming. The second category asks users to declaratively define non-standard charts with their logical specification using a given library of graphical objects. Here we will propose a new visualization framework in the second category for automatically constructing non-standard charts from their logical specifications and discuss how to apply our framework to create custom-made geovisualization charts. Such a specification is described by one or more pairs of data view schemata (DVSs) and chart view schemata (CVSs). Each DVS is used for manipulating the data store in a database. Each CVS is used for defining the rendered appearances of the different chart components. Using our framework, users can easily re-create and extend such complex non-standard charts as the chart of Napoleon's campaign by simply providing their logical specifications.. |

Randy Goebel, Shi Wei, Yuzuru Tanaka, The challenge of semantic symmetry in visualization, Proceedings of the International Conference on Information Visualisation, 10.1109/IV.2014.32, 27-33, 2014.09, We present a fundamental problem which arises within an emerging theory of visualization, and provide examples that illustrate the challenge of what we call semantic symmetry. This theory of visualization distinguishes data domains (e.g., Numbers and symbols) from picture domains (e.g., Shapes, shading, colour), and provides a framework for specifying a variety of mappings between data and picture domains. Visualization is about enabling inferences about data within the human visual system, so crucially depends on the management of mappings from the data to the picture domain. But there are many possible choices for these mappings, and only in the last decade has there emerged any serious assessment of how one might measure the quality of a visualization. The situation is further complicated by what is now called visual analytics, where data to picture mappings allow manipulation of that picture to further understand or reveal the underlying data relationships. This kind of picture manipulation is exactly the departure point for our presentation of the problem of semantic symmetry. Semantic symmetry considers the problem of how to couple data and picture so that changes in one are accurately reflected in the other. We illustrate the foundational nature of the problems arising from the desire for semantic symmetry, and explain the kinds of constraints and framework that are necessary in order to be able to support a more complete theory of visualization.. |

Randy Goebel, Wei Shi, Yuzuru Tanaka, The role of direct manipulation of visualizations in the development and use of multi-level knowledge models, Proceedings of the International Conference on Information Visualisation, 10.1109/IV.2013.95, 325-332, 2013.07, The proliferation of touch sensitive display screens has created a new generation of human-computer interaction styles which are so natural and common that even the youngest of users now perceive ordinary static media like a glossy magazine as a broken iPad. The volume of users who expect to be able to pinch, grab, twist and manipulate images on screen is rapidly growing
they drive a renewed interest in developing, assessing, and delivering new direct manipulation systems. Our premise is that one can exploit new technologies to develop new repertoires of direct manipulation, but with increasing pressure to provide semantically-coupled direct manipulation methods to experiment with computational information models. We develop this premise by noting highlights in the evolution of direct manipulation interfaces, and suggest that their selection and deployment can be tailored as visual experiments to debug and extend more complex computational models of information systems and processes. These systems and processes include those of natural systems such as arise in systems biology (e.g., modelling multiple levels of protein structure), but also in 'unnatural' systems such as in the identification of hubs and authorities in artificial systems like the World Wide Web (WWW). The immediate consequence of our premise suggests that the design of direct manipulation tools should proceed with the semantics of the modelled systems in mind, so that each users' manipulations provide a new perspective on the concept of 'data mining' of large data sets. This will allow users to not just expose implicit relationships, but to incrementally combine explanatory and exploratory investigation by direct manipulation, to adjust and improve the computational knowledge models that emerge from the underlying data. © 2013 IEEE.. |

W. Shi, Y. Tanaka, Object-oriented graphical-template composition framework for information visualization, IET Conference Publications, 10.1049/cp.2010.0591, 2010, 568, 378-383, 2010.09, 2D visualization of data is an important tool to improve human's comprehension of abstract data. However, because of the increasing amount of data, simple charts are becoming obsolete. Thus, we propose a new framework to help users easily create complex charts. In our framework, we first describe a method of combining primitive basic shape objects together to create complex templates to represent records and aggregates of records. We then describe a formal model through which users can retrieve object-oriented data. The retrieved data is then directly associated with record or aggregate templates to be visualized. Under the help of our framework, the visualization will become more flexible and easier to construct. Moreover, we have implemented our framework as a web visualization tool so that it can be shared and extended easily by any web users.. |
