Due to the potential cluttering and occlusion problems, slow speed and poor interactivity as well as the influence of perspective to the effects of display, 3D visualization techniques have been controversial in the field of information visualization. To address these problems, this paper proposes a novel 3D trajectory visualization method employing the immersive virtual reality technology. Compared with the traditional 3D trajectory visualization methods, our method breaks the limitations of the traditional 2D display of 3D visualization, and engages users in a virtual world with optional perspective to observe 3D visualization without over-plotting. Through practical experiments, our work can reduce the over-plotting of 3D visualization results, and provide smooth transition between visualization views and interactions.","PeriodicalId":399556,"journal":{"name":"Proceedings of the 8th International Symposium on Visual Information Communication and Interaction","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128522755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large high-resolution displays can facilitate the analysis process since they offer more screen real estate than desktop monitors, which allows visualizing more data in greater detail and working collaboratively. On the other hand, mobile devices like smartphones and tablets are getting more and more popular but do not have sufficient graphics capabilities for advanced scientific visualizations. In this paper, we discuss a client application for Android devices that allows to remote control a scientific visualization framework. Combining the power of remote rendering with the availability, flexibility, and mobility of mobile devices results in a ubiquitous computing solution for scientific visualization. The user interaction with a large high-resolution display is only one possible application scenario. Other scenarios include presentation of results and remote visualization. The design of our Android application fulfills the requirement of all these application scenarios.","PeriodicalId":399556,"journal":{"name":"Proceedings of the 8th International Symposium on Visual Information Communication and Interaction","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129113254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with such a diverse population a universal mode of delivering education must be sought. This paper places the artist at the heart of educating patients and carers about their disease by developing a technical process of delivering 3D CT patient stroke data on the Virtual Reality (VR) platform Oculus Rift DK2. VR has already been proven as an efficacious rehabilitation tool for this population but its use in education has not yet been established. This work is being piloted in a new collaboration between the Art & Design Faculty at the University of New South Wales, Australia and the Stroke Rehabilitation Service at St Vincent's Hospital in Sydney. Importantly, this paper places the artist's at the center of the process -- from developing the concept, to prototyping and creating the final visual aesthetic. The different stages of the technical design process are also described in this paper. These provide an early framework for working with VR in a clinical context. The practicalities and pitfalls of navigating vascular datasets in immersive real-time 3D on VR are discussed at the end of this paper. Several recommendations for the future development of this process and its scalability for clinical use are made.","PeriodicalId":399556,"journal":{"name":"Proceedings of the 8th International Symposium on Visual Information Communication and Interaction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129584844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emphasis is specifically on showing content evolution and modification with passage of time. The challenge lies in presenting not only the content as a stand-alone but also understand how the present is related to the past. For example analyzing large volumes of emails can show how communication among a set of people have progressed or evolved over time, may be along with the roles of the communicators. It can also show how the content has changed or evolved. In order to depict the changes, the email repositories are first clustered using a novel algorithm. The clusters are further time-stamped and correlated. User-insights are provided through visualization of these clusters.

Code ownership is commonly determined by investigating the data from version control systems, defining the owner as the person who contributed the most lines to a file, module, etc. Existing visualisation for ownership usually relies on per-line annotations from the version control system, thus only conveying the information who changed a line the last time, potentially adding some visual cue about how old the respective change is. This, however, can be misleading, because any change of even a single character changes ownership. In this paper, we propose a visualisation that accounts for fractional ownership changes over time on a per-character basis. Our technique incorporates visual cues to convey that typical definitions of ownership have an inherent uncertainty and provides details on the cause of this uncertainty on demand. For our definition of code ownership being a low-level one, we propose implementing the visualisation as an in-situ visualisation in the code editor of modern development environments. We will show examples of the efficacy of our approach and discuss its advantages and disadvantages compared to conventional line-based ownership.","PeriodicalId":399556,"journal":{"name":"Proceedings of the 8th International Symposium on Visual Information Communication and Interaction","volume":"18 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131844230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Map-like visualisations, which resemble geographic maps, can be a useful tool for perceiving hierarchical information. Maps have the advantage that the majority of ordinary users can easily understand them without prior training. This paper presents a novel method for visualising hierarchical data in a form resembling a geographic map, using hexagon tiling. Our method can be used for visualising general hierarchical data, such as organisational structures, library catalogues, file systems, and many more. Like treemaps, our new method is area-based, thus it not only reveals hierarchy but also other attributes. Unlike treemaps, however, our method produces visualisations that resemble geographic maps in shape and appearance. Several tactics are employed to control the space-division process and aspect ratio. In this paper we present experiments involving our visualisation, evaluations of results, comparisons with other methods, and discuss advantages and potential issues.","PeriodicalId":399556,"journal":{"name":"Proceedings of the 8th International Symposium on Visual Information Communication and Interaction","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134068964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a system for product retrieval inspired by psychology of women's shopping activity, and an implementation of the system for apparel products. Our study supposes products which pre-defined keywords are assigned, and prepares icons representing the combination of the keywords. The system intuitively displays various icons in a display space to demonstrate the diversity of the products. When a user selects an interested icon, the system switches the display to a set of images corresponding to the selected icon, so that the user can visually compare the similar products. The system also features user interfaces to input the preference of users, and reflects the input to the evolutionary computation which adjusts the selection of icons to their preferences. It acts real shopping behavior because we often firstly look over the shops to understand the diversity of products, and then close up the particular groups of the products.
