The first step of any information visualization system is to enable end user to import their dataset into the system. However, non expert user are faced to the difficult task of choosing how their data should/could be transform to be used in these Infovis systems. In that paper we address the case where end users want to use dataset in tabular format. We propose a novel method for automatic graph generation from these datasets. That method consists in first building taxonomy of dimensions. Then, that taxonomy is used to provide to user a system that enables to interactively navigate into the set of possible data transformation.

The existing techniques used for post stroke rehabilitation have sought to offer stroke survivors with upper extremity motor deficits a system for the practice and re-learning of motor tasks. Some studies suggest that the use of Virtual Reality technologies as an assistive technology in combination with conventional therapies can achieve improved results in post stroke rehabilitation. Despite the wealth of ongoing research attempting to build a virtual reality based system for upper extremity rehabilitation, there still exists a need for a training platform that would provide whole arm rehabilitation. In order to be practical this system should ideally be low cost and involve minimal therapist involvement. This paper describes some of the applications of virtual reality that have undergone clinical trials with patients suffering from upper extremity functional motor deficits. A brief description of VR technologies that are in place, providing benefits to the stroke patients with upper extremity motor and functional deficits, alongside a proof of concept of a whole arm rehabilitation platform is presented.

Interactions are central to our endeavours. Whether in a face-to-face session with a doctor or via one of Web 2.0 applications, the way interactions unfold has an impact on the final outcome of the session. This paper addresses the problem of the development of a visual language and analysis system, enabling visual reasoning about the quality of interactions. The paper presents a system of encoding the way interactions unfold. It presents the foundations of KIA (Kinetic Inter-Acting) visual language and the visual analysis system with this language. The language is then evaluated through comparison with expert judgments when applied to cases in health care. KIA (the language and the analysis system) enables both humans and machines to utilise information about how interactions unfold in order to improve interactions and the processes that depend on them.

There have been two types of Web visualization techniques: visualization of Web sites themselves based on such as link structures or lexical contents, and visualization of browsers’ behaviors. We think that integration of such two visualization techniques is very useful for Web site management, and therefore we are currently studying on visualization of access pattern and link structure on a single screen. This paper presents a Web visualization technique using our own multiple-category-embedded graph visualization technique. The presented technique constructs link structures using crawler software, and access patterns from access log files. It then integrates them and visualizes by our graph visualization technique. We expect that users can visually understand the relationship between access patterns and link structures, and utilize the knowledge for design and management of Web sites. This paper shows our case study and discusses typical access patterns we observed by the technique.

This paper holds as its core objective the report of the research developed towards the conceptualisation and prototyping of an Information Visualisation system capable of providing a quick and accurate view of the set of data collected by the SAPO Broker web service regarding access activity in the SAPO news website. SAPO Broker, a real-time monitoring application that collects data generated by every type of activity within the SAPO Web Portal. The research presented and its results undertook two major challenges: i) design a visual metaphor capable of integrating news related collected data for a specific target audience, technology setup and context of use; ii) design user friendly and context valid interaction tools able to assist data analysis and help improve news editorial related tasks. Throughout this paper the need for transdisciplinary teamwork and diverse scientific knowledge correlation is reinforced, as we believe it should be when the core issue is Information Visualisation.

This paper presents a report of a system that delivers customized video content to mobile devices. Constructed from open source components, it can stream transcoded video to mobile devices in real-time. In addition, it allows publishers to add content into their video streams on-the-fly. As a demonstration of this system's capabilities, an application was designed to deliver transcoded Adobe Flash content to Apple iPhones in real-time with the insertion of randomly selected commercial content.

We represent time-varying data as polyline charts very often. At the same time, we often need to observe hundreds or even thousands of time-varying values in one chart. However, it is often difficult to understand such large-scale time-varying if all the values are drawn in a single polyline chart. This paper presents a polyline-based 3D time-varying data visualization technique. The technique places a set of polylines in the 3D space, where the X-axis denotes time, the Y-axis denotes values, and the polylines are arranged along the Z-axis. It provides two views: the first viewpoint has a view direction along Y-axis, and the second viewpoint has a view direction along Z-axis. The technique displays the overview of the data from the first viewpoint, and the detail of the specific parts of the data from the second viewpoint. It also detects frequent or outlier patterns by applying SAX (Symbolic Aggregate approXimation), and indicates them so that users can discover such characteristic patterns. This paper shows several interesting visualization examples to demonstrate the effectiveness of the presented technique.

Awareness of shared work activities is important for fostering professional relationships. This paper introduces visualization techniques for a meeting support system based on automatic speech recognition and multisensory meeting information capture, including voice levels and participant comments. The system has been deployed in live meetings over the past 5 months and we report meeting participants’ expectations and findings from a field study. Initial findings suggest that the proposed approach can facilitate awareness without the need for detailed meeting transcriptions and associated audio recordings, however the quality of speech recognition results and their effective visualization remain critical factors for increased adoption.

This paper presents a user study performed to compare the usability of the Wiimote as an input device to visualize information and navigate in Google Earth using two different configurations. This study had the collaboration of 15 participants which performed a set of tasks using the Wiimote as an input device while the image was projected on a common projection screen, as well as a mouse on a desktop. Results show that most users clearly preferred one of the Wiimote configurations over the other, and over the mouse; moreover, they had better performances using the preferred configuration, and found it easier to use.
