To achieve such usability we use various methods from user centered design up to the usability evaluation methods, requiring much attention from usability experts. The presense of these experts are needed both during capturing and analysing usability data, which eventually costs too much. We propose a tool for automated data capturing during user tests as well as a captured data analysis in order to evaluate the recorded interaction and guide the attention of software developers. Furthermore we provide a simple statistics of user tests as well as a means to browse recorded data with the interaction context extended with eye tracking data.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"15 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":"122518935","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 requires the quick production of a sequence of graph visualizations. However, the traditional force-directed graph drawing algorithms are very slow to reach an equilibrium configuration of forces. They usually spend tens of seconds producing the layout of a graph converge. Thus, they do not satisfy the requirement of rapid drawing of graphs. This paper proposes a fast convergence method for drawing force-directed graphs. We essentially pre-calculate the geometrical position of all vertices before applying a force-directed layout algorithm to reach the energy minimization of the graph layout. The experimental results have shown that this approach could not only reduce the convergence time but also the number of edge crossings that approves the quality of layout significantly.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"44 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":"115901493","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 particular image mosaicing is used to assemble several overlapping images in order to constitute the global frame. We will focus on a feature-point matching method to perform the mosaicing. The SIFT algorithm is used to extract the feature points in both images. The mosaicing result is obtained after transforming the sensed or target image to align to the reference image. Performing a mosaicing operation is not sufficient to claim reaching the goal. Objective metrics must be used to evaluate the resulting mosaic. In this paper we present a complete mosaicing system named EsiReg and give a brief comparative insight on results of stitching satellite and aerial images using well known performance metrics.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"25 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":"123073716","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 general, the performance of Web image search depends on the quality of images annotation, but often the keywords (or tags) associated to an image are given without relevance information, strictly connected to a subjective feeling of the taggers and far from the objective description of the image. In this paper, we propose a simple approach for social media sharing web sites such as Flickr, Zooomr, etc. to support users to retrieve images semantically correlated to a given tagged image. In this paper, we present an application scenario for Flickr: in general Flickr returns all the images that meets the input tags, without no semantic analysis and evaluation of the effectiveness of the search results. Our approach adds a semantic layer on the Flickr output: processes the tags associated to the retuned images to discover the appropriate semantics of them, by arranging the results in a more user friendly view.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"23 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":"127652531","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}

For example, the edge design of traditional settlements in historical cities and blocks determines the basic size, space and shape of the space. However, unlike the space designed in paper, the formation of edges of traditional settlements are the presentation of residents' public consciousness in the settlements, value orientation and behaviour law under the long-term historical influence, rather than the expression of the designer's personal moment will. This topic cites some traditional cities and settlements of Fujian sea system in China as example and use the boundary as research subject in order to present non-objective historical documents hidden in this system in details by researching documents, field study and chart analysis.

We are now able to fill and stratify space/time with digital information layers, completely wrapping cities in a membrane of information and of opportunities for interaction and communication. Mobile devices, smartphones, wearables, digital tags, near field communication devices, location based services and mixed/augmented reality have turned the world into an essentially read/write, ubiquitous publishing surface. The usage of mobile devices and ubiquitous technologies alters the understanding of place. The scenario described in this paper sees urban spaces progressively filling with multiple layers of real-time, ubiquitous, digital information, creating usage cases in which urban narratives are read in different ways, highlighting how cities express points of view on the environment, culture, economy, transports, energy and politics. The research presented in this paper analyses multiple opportunities to capture, understand and visualize the real-time digital lives of cities, from a variety of points of view and objectives, dedicated to the needs of administrations, citizens and organizations, and to the possibility to transform these representations into a form of disseminated, ubiquitous, interconnective intelligence.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"T165 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":"125413053","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}

People now actively use information technologies to seek out and understand the opinions of others. This is due to the availability and popularity of opinion-rich resources such as online review sites and blogs. The accommodation sector is one of those where the guest opinion dictates its future. This sector needs to adapt and update the services they offer to their guests in order to stay competitive. In this paper we outline the potential use of tree-oriented visual techniques to map 1500 online reviews collected from 50 small and medium hotels (SMH). Our goal is to deliver visually the results of these reviews as straightforward and intuitively as possible to the accommodation managers, enabling them use it to support their decision making.","PeriodicalId":264951,"journal":{"name":"2012 16th International Conference on Information Visualisation","volume":"39 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":"128363730","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}
