Tree Visualisation and Navigation Clues for Information Visualisation

Information visualisation often requires good navigation aids on large trees, which represent the underlying abstract information. Using trees for information visualisation requires novel user interface techniques, visual clues, and navigational aids. This paper describes a visual clue: using the so-called Strahler numbers, a map is provided that indicates which parts of the tree are interesting. A second idea is that of "folding" away subtrees that are too "different" in some sense, thereby reducing the visual complexity of the tree. Examples are given demonstrating these techniques, and what the further challenges in this area are.     

VR-VIBE: A Virtual Environment for Co-operative Information Retrieval

We present a virtual reality application called VR-VIBE which is intended to support the co-operative browsing and filtering of large document stores. VR-VIBE extends a visualisation approach proposed in a previous two dimensional system called VIBE into three dimensions, allowing more information to be visualised at one time and supporting more powerful styles of interaction, The essence of VR-VIBE is that multiple users can explore the results of applying several simultaneous queries to a corpus of documents. By arranging the queries into a spatial framework, the system shows the relative attraction of each document to each query by its spatial position and also shows the absolute relevance of each document to all of the queries. Users may then navigate the space, select individual documents, control the display according to a dynamic relevance threshold and dynamically drag the queries to new positions to see the effect on the document space. Co-operative browsing is supported by directly embodying users and providing them with the ability to interact over live audio connections and to attach brief textual annotations to individual documents. Finally, we conclude with some initial observations gleaned from our experience of constructing VR-VIBE and using it in the laboratory setting.

Interactive data visualisation for accounting information: a three-fit perspective

The volume of freely available accounting information is rapidly becoming overwhelming. To be useful, information needs to be delivered to users in a suitable, relevant, and understandable form. Interactive data visualisation (IDV) can help address this need for useful information by organising accounting information, especially financial reports, into forms with these qualities. Given both their prevalence and their likelihood of being future users of IDV, the purpose of this research is to examine the appropriateness of IDV for non-professional investors’ use when they access accounting information. This research uses a 2 × 2 experimental approach involving 404 participants representing non-professional investors from diverse demographic backgrounds. This research suggests that IDV mitigates non-professional investors’ restricted investment capabilities by presenting information that is more salient, thus reducing non-professional investors’ cognitive effort. This combination allows such investors to better perform both simple and multipart investment tasks. By integrating three information systems’ fit perspectives (i.e. task technology, information quality, and cognitive), this research explains IDV’s suitability and fit within the accounting domain. We also discuss how the findings can inform practice and span interdisciplinary research into data and information visualisation.     

Graphical Information Portals—The Application of Smart Maps in G≻eoN≻et 4D

This paper presents a new brand of portals that elevates the concepts of information portals to a new level of interaction and navigation means. The graphical information portal is built upon the concept of smart maps for information visualization and exploration. Smart maps serve as navigational hub by indicating the existence of information carrying relevance for a specific location, by relating distributed multimedia information to a location on a map of interest, and by categorizing information for easier orientation in subjects. Main advantage of a map-based information portal lies in the intuitive information presentation, navigation, search and retrieval. Representative usage scenarios include facility management, information kiosks, and environmental information systems. Groupware functions for collaborative visualization and interactive editing on maps are added on top in order to migrate the concept of graphical information portals to further domains, such as concurrent engineering, risk management, and the like. An implementation of a geographical information portal has been designed and implemented in project GeoNet 4D, focussing on facility management for portuary zones.     

A Characterization of Interactive Visual Data Stories With a Spatio-Temporal Context

Large-scale issues with a spatial and temporal context such as the COVID-19 pandemic, the war against Ukraine, and climate change have given visual storytelling with data a lot of attention in online journalism, confirming its high effectiveness and relevance for conveying stories. Thus, new ways have emerged that expand the space of visual storytelling techniques. However, interactive visual data stories with a spatio-temporal context have not been extensively studied yet. Particularly quantitative information about the used layout and media, the visual storytelling techniques, and the visual encoding of space-time is relevant to get a deeper understanding of how such stories are commonly built to convey complex information in a comprehensible way. Covering these three aspects, we propose a design space derived by merging and adjusting existing approaches, which we used to categorize 130 collected web-based visual data stories with a spatio-temporal context from between 2018 and 2022. An analyzis of the collected data reveals the power of large-scale issues to shape the landscape of storytelling techniques and a trend towards a simplified consumability of stories. Taken together, our findings can serve story authors as inspiration regarding which storytelling techniques to include in their own spatio-temporal data stories.

Empirical Study of a 3D Visualization for Information Retrieval Tasks

There are many challenges to visualizing information including choosing between 2D and 3D interfaces, navigation and interaction methods, and selecting an appropriate level of detail. Visualizing information retrieval (IR) search results, including Web search engine results, poses additional challenges, notably the determination of appropriate relative locations for terms and document in a visual display. Latent Semantic Indexing (LSI) and related techniques offer approaches to visualizing relations among terms and documents. In this work, information space is presented as a framework for discussing relations among terms and documents, and a technique related to LSI is utilized to generate information spaces from IR search results. This paper provides an overview of more than three decades of work on information visualization, identifying several trends and some relatively unexplored areas. An experimental evaluation of a prototype interface for visualizing IR results is described. Results indicate that the 3D navigation interface for IR search results was usable, but that subjects had difficulty with some aspects. Further study and development of 2D and 3D methods for interacting with retrieval search results is suggested.
