Such time-varying data is often associated with other information: for example, temperatures can be associated with weather, and stock prices can be associated with social or economic incidents. Meanwhile, we often draw large-scale time-varying data by multiple polylines in one space to compare the time variation of multiple values. We think it should be interesting if such time-varying data is effectively visualized with their associated information. This paper presents a technique for polyline-based visualization and level-of-detail control of tagged time-varying data. Supposing the associated information is attached as tags of the time-varying values, the technique generates clusters of the time-varying values grouped by the tags, and selects representative values for each cluster, as a preprocessing. The technique then draws the representative values as polylines. It also provides a user interface so that users can interactively select interesting representatives, and explore the values which belong to the clusters of the representatives.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114419995","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}

In [13] based on ESOM and some of its derivatives, U-Matrix and P-Matrix, a powerful automated clustering algorithm, U*C, is introduced, and it is shown that the algorithm performs better than the some of the benchmark algorithms. However, the mentioned algorithm is suitable for partitional clustering tasks, while in most of the real cases, because of the nature of the data sets (not the ESOM training algorithm) a hierarchical structure in the data can be assumed. In this paper, based on the main ideas of U*C algorithm and underlying meaning of the U-Matrix, we introduced an automated hierarchical clustering algorithm, which performs well for real data sets. After testing with some test cases, we applied the proposed algorithm on a real data set, including different energy, ICT and Urban related indicators of European and central Asian countries. The proposed algorithm identified the hierarchical groups among the selected countries.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124220263","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, most existing techniques restrict their partitioning process in vertical and horizontal direction only, which cause problem with identifying hierarchical structures. This paper presents a new space-filling method named Angular Treemaps that relax the constraint of the rectangular subdivision. The approach of Angular Treemaps utilizes divide and conquer paradigm to visualize and emphasize large hierarchical structures within a compact and limited display area with better interpretability. Angular Treemaps generate various layouts to highlight hierarchical sub-structure based on user's preferences or system recommendations. It offers flexibility to be adopted into a wider range of applications, regarding different enclosing shapes. Preliminary usability results suggest user's performance by using this technique is improved in locating and identifying categorized analysis tasks.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124463107","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}

Most contracts are complex, as is the business they describe. Contracts are not easy to read, and their misinterpretation can cause expensive disputes between the parties. Recent research suggests an alternative to contracts written in legalese, by harnessing the benefits brought by plain language and plain design. Clarity and user-friendliness present a challenge on multiple levels: the contract as artefact, the cognitive capabilities of the readers, and the different contexts in which the contract may be used. This paper focuses on the artefact level. Using recent examples of contract visualization, we investigate ways in which text and images can work together to address the needs of different readers and help them use contracts to secure successful business outcomes.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126516313","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 enormous scaling gap between an atomic point of view and objects in daily life hampers developing an intuitive relation between them. Especially for high school students, it can be difficult to understand the spatial relations of a protein structure. Due to lack of direct imaging techniques, molecules can only be explored by studying abstract molecular models. Here, the use of Augmented reality (AR) techniques has proven to strongly improve structural perception. In this work we present ProteinScanAR, an augmented reality framework for biomolecular education that allows connecting virtual and real worlds intuitively, and thus enables focusing on the scientific or educational content. Special attention was taken to guarantee implementational and technical requirements as general and simple as possible to alleviate application in nonexpert computer settings.

With the data gathered from an eye tracker, it is possible to discern viewers' main focus of attention. However, in the case of video media, the visualisation tools of eye tracking software are insufficient for this discernment. This method uses eye tracking log files and combines them with algorithms developed using a spreadsheet application and visual data representation techniques. As a result of this combination, it is possible to identify the graphics which have greater visual attention, and subsequently, these representations supported the analysis of viewers' main focus of attention (areas of interest). A case study was also applied for the validation of this method.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132121120","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 constellation issues challenges to both: exhibition designers who have to find ways to deal with spatial restrictions and visitors who often experience cognitive overload and museum fatigue due to the high amount of information available. Against this background, the article is focusing on the question, how information visualization can serve as advance organizer, to make the organizing principles of cultural heritage exhibitions (like common topics, themes, geographical or temporal origin) transparent to the visitors. For this purpose, we extend the visualization method of time geography to an interactive visualization framework of time topography, which can support the interactive exploration of conceptual and physical cultural heritage exhibition spaces in parallel.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131166793","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}
