In this paper, we describe a new approach that can be used in real application where graph does not contain only topological information but also extrinsic parameters (i.e. user attributes on edges and nodes). In the case of force-directed algorithm, management of attributes corresponds to take into account edge weights. We propose an extension of the GRIP algorithm in order to manage edge weights. Furthermore, by using Voronoi diagram we constrained that algorithm to draw each cluster in a non overlapping convex region. Using these two extensions we obtained an algorithm that draw clustered weighted graphs. Experimentation has been done on data coming from biology where the network is the genes- proteins interaction graph and where the attributes are gene expression values from microarray experiments.","PeriodicalId":177429,"journal":{"name":"2007 11th International Conference Information Visualization (IV '07)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116854272","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 an experimental study the affective appraisals of the original and the manipulated models were compared. Results demonstrate that unfavourable elements in an urban environment, that are usually omitted from 3D models, influence the appraisal of the participants about the area, but only slightly and less than expected. Moreover, the judgment of the environment seems to be influenced by expectations of the representation. When 3D models are used for decision making in urban planning, this effect has to be taken into account. The experiment thus demonstrates that measuring instruments should be designed in such a way that the content (the environment) can be assessed separately from the chosen representation.","PeriodicalId":177429,"journal":{"name":"2007 11th International Conference Information Visualization (IV '07)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115128301","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}

From this data, bare earth digital terrain models (DTMs) can be processed semi-automatically, then draped with aerial imagery. The paper describes an approach developed in the VEPs project that switches on the LiDAR data for trees and buildings removed from the DTM in the 3D Scene. This data can then be used to visually judge the appropriate height and form of buildings and trees. A set of web-based interactive tools have been developed to enable users to freely adjust the scale and mass of structures and vegetation to match the selected point cloud area, substantially improving the quality of presence and accuracy of the resulting model.

Our system works by tracking the user's head position and orientation to obtain their 'gaze' point on a virtual screen, and by indicating to the user what object is present at the gaze location via haptic feedback to the fingers and synthetic speech or Braille text. This is achieved by using the haptic vibration frequency delivered to the fingers to indicate the type of screen object at the gaze position, and the vibration amplitude to indicate the screen object's window-layer, when the object is contained in overlapping windows. Also, objects that are gazed at momentarily have their name output to the user via a Braille display or synthetic speech. Our experiments have shown that by browsing over the screen and receiving haptic and voice (or Braille) feedback in this manner, the user is able to acquire a mental two-dimensional representation of the virtual screen and its content without any use of the eyes. This form of blind screen perception can then be used to locate screen objects and controls and manipulate them with the mouse or via gaze control. Our experimental results are provided in which we demonstrate how this form of blind screen perception can effectively be used to exercise point-and-click and drag-and-drop control of desktop objects and open windows by using the mouse, or the user's head pose, without any use of the eyes.","PeriodicalId":177429,"journal":{"name":"2007 11th International Conference Information Visualization (IV '07)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126708182","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}

Many current techniques involve reducing the dimensionality of the data, which results in a loss of information. Targeted Projection Pursuit is a novel method for visualising high-dimensional datasets which allows the user to interactively explore the space of possible views to find those that meet their requirements. A prototype tool that utilises this method is introduced, and is shown to allow users to explore data through an interface that is transparent and efficient. The tool and underlying technique are general purpose - applicable to any high-dimensional numeric data, and supporting a wide range of exploratory data analysis activities - but are evaluated on three particular tasks using gene expression data: identifying discriminatory genes, visualising diagnostic classes, and detecting misdiagnosed samples. It is found to perform well in comparison with standard techniques.","PeriodicalId":177429,"journal":{"name":"2007 11th International Conference Information Visualization (IV '07)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126850614","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}

I-Musika: MIME (mobile interface musical expression) is a multidimensional interface that seeks to integrate at least three \"disjoint neighborhoods\" or entities: \"keys, instruments and players\". Based on the frequency resonating structures modeling paradigm, I-Musika: MIME transfigures the properties and geometry of musical instrument and unifies the excitation methods for different instruments, thus offering multiple (distinct) designs for a single instrument or a single design for multiple (distinct) instruments via an interface that provides contact free playing. As such, not only it transforms the keys-instruments-players relationship and creates new performing style that is insensitive to posture, hand and finger positioning, it creates a new audience-player-instrument profile. Harnessing the properties of this interface, I-Musika: MIME, the new instrument is portable with an artistic physical appearance or visual representation as desired. It can be modified and achieved as you pleased to add another dimension to musical pleasure. This paper presents the framework of the conceptual communication paradigm between key to instrument, instrument to instrument and instrument to player, as described.

Available graph visualization techniques could perform well for small or medium size graphs but they are rarely able to handle very large and complex graphs. One of effective approach to solve this problem is to employ graph abstraction; that is to hierarchically partitioning the complete graph into a clustered graph. A graph visualization technique is then applied to display the abstract view of this clustered graph with partially displayed detail of one or a few sub-graphs where the user is currently focusing on. This reduces the complexity of display and makes it easier for users to interpret, perceive and navigate the large scale information. In this paper, we propose a graph clustering method which can quickly discover the community structure embedded in large graphs and partition the graph into densely connected sub-graphs. The proposed algorithm can not only run fast, but also achieve a consistent partitioning result in which a graph is divided into a set of clusters of the similar size in terms of their visual complexity and the number of nodes and edges. In addition, we also provide a mechanism to partition very dense graphs in which the number of edges is much larger than the number of nodes.","PeriodicalId":177429,"journal":{"name":"2007 11th International Conference Information Visualization (IV '07)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121191982","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 virtual environments analysed in this paper are complex mechanical sets that are not densely occluded. Those which are built up by dense geometric sets like aerospace engines composed of thousands of components and millions of polygons. The algorithm uses occlusion queries and succeeds in improving the frame rate of the stereoscopic visualization with an effective scheduling of the queries. Different coherences, including stereo coherence, are used to achieve this effective scheduling. An aggressive approach has been also validated for inclusion in the proposal. The occlusion culling algorithm can be easily implemented and provides a significant boost in performances.","PeriodicalId":177429,"journal":{"name":"2007 11th International Conference Information Visualization (IV '07)","volume":"73 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121372849","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}
