Several variations of Treemap have been developed to represent different types of data. In this paper, we propose an Edge Equalized Treemap, a representation that embeds visual data such as a bar chart in leaf rectangles. This representation is characterized by leaf rectangles of equal widths. Because their widths are equal, the scale intervals of charts in a leaf rectangle can be unified, meaning that we can compare charts simply by looking at them. We compare the Edge Equalized Treemap with existing layout methods, and demonstrate the usefulness of our approach.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"81 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":"130608348","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}

It starts with an analysis of the notion of Augmented Reality, that leads to the construction of a conceptual model and a definition which together capture the nature of present AR applications. This is followed by a detailed conceptual analysis of major types of Augmented Reality that contribute to an understanding of current concepts. Finally, the resulting conceptual models are applied to the newly emerging field of Augmented Reality Art in order to assess the paradigmatic potential of AR as a new artistic medium. The paper puts a strong emphasis on the effective and adequate visualisation of the analysed conceptual frameworks, in order to promote a better comprehension of the logical structures underlying the notions of Augmented Reality and AR Art. This paper was intended to be presented at the opening of the First International Symposium on Augmented Reality Visualisation and Art, proposed and chaired by the author as part of the 16th International Conference on Information Visualization, IV2012.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"131 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":"133276308","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}

To solve this problem, we develop a user assistant that performs 2 steps: the system starts by suggesting to users different mappings between their data and possible visualizations. This is performed with a simple but generic heuristic that can be applied to any visualization. Then, the user selects a visualization among those proposed by our assistant, and he may further improve the parameters set that defines the mapping between the visual attributes and the data attributes. For this purpose, we use an interactive genetic algorithm (IGA), which allows users to visually evaluate and adjust the mappings. We present a user evaluation that confirms the interest of our system in two tasks.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"72 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":"124026584","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}

It is an iterative algorithm based on the minimization of an objective function. A major weakness of subspace clustering algorithms is that almost all of them are developed based on within- class information only or by employing both within-cluster and between- clusters information. The density of cluster is lost. The new function is developed by integrating the separation and compactness of clusters. The density of cluster is introduced also in the compactness term. The experimental results confirm that the proposed algorithm gives good results on different types of images by optimizing the runtime.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"45 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":"129070393","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}

Diagram visualisation does not help much because of visual clutter caused by big amount of elements and connections, especially in the case of flat component models. This paper describes a novel approach of removing a large part of connections from the diagram while preserving the information about component interconnections. It uses a separated components area to show the components with big amount of connections. For each component in this area, clustered interfaces are shown instead of all interfaces, with the ability to show details on demand. The main idea of this technique can be used in a similar way to reduce the clutter in node-link graphs. To show the effect of this technique we discuss example lines reductions for several component applications.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"65 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":"115849283","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 the implemented prototype, the user interacts with a collection of pictures to receive new music recommendations from associated genres. The prototype was evaluated by 40 Finnish participants. After the first use of the prototype, the concept of selecting music based on mood pictures was found to be very good by 85% of the participants. In the longer-term use, the prototype lacked some important features such as the ability to personalize the picture and music associations. Despite this, 60% of the participants were interested in using the prototype to complement their other music player applications. This indicates that mood pictures are a promising way to access music collections and to explore new music.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"68 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":"114247096","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}

A feature of the data is that each event may have one or more time-stamps. By analyzing this kind of data, we are able to find some behavioral patterns and obtain knowledge applicable to many fields, such as marketing research and security. We develop ChronoView, a visualization technique to support the analysis of data with temporal information. ChronoView represents an event with a set of time-stamps as a position inside a circle, similar to the dial of an analog clock. By representing each event as a position on a two-dimensional plane, we can simultaneously visualize many events and easily compare their occurrence patterns. We implement a tool based on ChronoView, which is enriched with additional functions and overcomes the drawbacks of the original system. A use case involving tweet data from Twitter illustrates the use and practicality of ChronoView.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"20 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":"126825224","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 approach takes advantages of familiar concepts such as forests of trees, sub-forest of trees, trunks, branches, leaves, and color of the leaves. In particular, each release of a software is represented as a forest that users (or software maintainers) can navigate and interact with. Users can pass from a release to another one, so understanding how the entire software and its classes evolve throughout the past releases. The approach has been implemented in a prototype of a 3D interactive environment.
