A useful starting point for designing advanced graphical user interfaces is the visual information seeking Mantra: overview first, zoom and filter, then details on demand. But this is only a starting point in trying to understand the rich and varied set of information visualizations that have been proposed in recent years. The paper offers a task by data type taxonomy with seven data types (one, two, three dimensional data, temporal and multi dimensional data, and tree and network data) and seven tasks (overview, zoom, filter, details-on-demand, relate, history, and extracts).

The eyes have it: a task by data type taxonomy for information visualizations

Never before in history has data been generated at such high volumes as it is today. Exploring and analyzing the vast volumes of data is becoming increasingly difficult. Information visualization and visual data mining can help to deal with the flood of information. The advantage of visual data exploration is that the user is directly involved in the data mining process. There are a large number of information visualization techniques which have been developed over the last decade to support the exploration of large data sets. In this paper, we propose a classification of information visualization and visual data mining techniques which is based on the data type to be visualized, the visualization technique, and the interaction and distortion technique. We exemplify the classification using a few examples, most of them referring to techniques and systems presented in this special section.

Information visualization and visual data mining

This is a survey on graph visualization and navigation techniques, as used in information visualization. Graphs appear in numerous applications such as Web browsing, state-transition diagrams, and data structures. The ability to visualize and to navigate in these potentially large, abstract graphs is often a crucial part of an application. Information visualization has specific requirements, which means that this survey approaches the results of traditional graph drawing from a different perspective.

Graph visualization and navigation in information visualization: A survey

The change of very first chart on page 91 was quite impressive and made me interest of the concept of maximizing data ink ratio. Today, unlike the period of 1980s, we have great quad processing computer that can do all the graphical designs using its own GPU which results in realistic visual on 3Ds. Even though I agree this theory of maximizing data ink ratio, I think some decoration is quite necessary to emphasize the data you are retrieving.

The Visual Display of Quantitative Information

As computers become more pervasive in society, facilitating natural human---computer interaction (HCI) will have a positive impact on their use. Hence, there has been growing interest in the development of new approaches and technologies for bridging the human---computer barrier. The ultimate aim is to bring HCI to a regime where interactions with computers will be as natural as an interaction between humans, and to this end, incorporating gestures in HCI is an important research area. Gestures have long been considered as an interaction technique that can potentially deliver more natural, creative and intuitive methods for communicating with our computers. This paper provides an analysis of comparative surveys done in this area. The use of hand gestures as a natural interface serves as a motivating force for research in gesture taxonomies, its representations and recognition techniques, software platforms and frameworks which is discussed briefly in this paper. It focuses on the three main phases of hand gesture recognition i.e. detection, tracking and recognition. Different application which employs hand gestures for efficient interaction has been discussed under core and advanced application domains. This paper also provides an analysis of existing literature related to gesture recognition systems for human computer interaction by categorizing it under different key parameters. It further discusses the advances that are needed to further improvise the present hand gesture recognition systems for future perspective that can be widely used for efficient human computer interaction. The main goal of this survey is to provide researchers in the field of gesture based HCI with a summary of progress achieved to date and to help identify areas where further research is needed.

Vision based hand gesture recognition for human computer interaction: a survey

The field of computer graphics combines display hardware, software, and interactive techniques in order to display and interact with data generated by applications. Visualization is concerned with exploring data and information graphically in such a way as to gain information from the data and determine significance. Visual analytics is the science of analytical reasoning facilitated by interactive visual interfaces. Expanding the Frontiers of Visual Analytics and Visualization provides a review of the state of the art in computer graphics, visualization, and visual analytics by researchers and developers who are closely involved in pioneering the latest advances in the field. It is a unique presentation of multi-disciplinary aspects in visualization and visual analytics, architecture and displays, augmented reality, the use of color, user interfaces and cognitive aspects, and technology transfer. It provides readers with insights into the latest developments in areas such as new displays and new display processors, new collaboration technologies, the role of visual, multimedia, and multimodal user interfaces, visual analysis at extreme scale, and adaptive visualization.

Expanding the Frontiers of Visual Analytics and Visualization

Computing devices within current work and play environments are relatively static. As the number of 'networked' devices grows, and as people and their devices become more dynamic, situations will commonly arise where users will wish to use 'that device there' instead of navigating through traditional user interface widgets such as lists. This paper describes a process for identifying devices through a pointing gesture using custom tags and a custom stylus called the gesturePen. Implementation details for this system are provided along with qualitative and quantitative results from a formal user study. As ubiquitous computing environments become more pervasive, people will rapidly switch their focus between many computing devices. The results of our work demonstrate that our gesturePen method can improve the user experience in ubiquitous environments by facilitating significantly faster interactions between computing devices.

We present the continuous zoom, a distorted view method for displaying hierarchically-organized, two-dimensional networks. The method is suitable for large networks, such as those found in interfaces to complex supervisory control systems. The continuous zoom shows detail in context, unlike simple pan and zoom techniques, and allows for more than one focus point, unlike fisheye viewing. The algorithm and variations are described. >

A continuously variable zoom for navigating large hierarchical networks

Many information systems are represented as twodimensional networks of links and nodes Because these networks tend to be large and quite complex, people often prefer to view part or all of the network at varying levels of detail Hierarchical clustering provides a framework for viewing the network at different levels of detail by superimposing a hierarchy on top of it Nodes are grouped into clusters, and clusters are themselves placed into other clusters Users can then navigate these clusters until an appropriate level of detail is reached This paper describes an experiment comparing two methods for viewing hierarchically clustered networks Traditional full-zoom techniques provide details of only the current level of the hierarchy In contrast, fisheye views (generated by the “variable zoom” algorithm described in this paper) provide information about higher levels as well Subjects using both viewing methods were given problem solving tasks requiring them to navigate a network, in this case a simulated telephone system, and to reroute links in it Results suggest that the greater context provided by fisheye views significantly improved a user’s performance of the tasks They were quicker to complete their task, and they made fewer unnecessary navigational steps through the hierarchy This validation of fisheye views is important for designers of interfaces to complicated monitoring systems, such as control rooms for supervisory control and data acquisition systems, where efficient human performance is often critical

Comparing Fisheye and Full-Zoom Techniques for Navigation of Hierarchically Clustered Networks

One of the key components of any training environment for surgical education is a method that can be used for assessing surgical skills. Traditionally, defining such a method has been difficult and based mainly on observations. However, through advances in modeling techniques and computer hardware and software, such methods can now be developed using combined visual and haptic rendering of a training scene. This paper presents some ideas on how metrics may be defined and used in the assessment of surgical skills in a virtual laparoscopic training environment.
