The idea is simple: instead of using clickstreams, keyboard input, and interaction logs to collect performance metrics for individual participants in a user study, the interaction data is aggregated from the running visualization, integrated back into the visual representation, and then the new interaction data is collected and evaluated with the old data. Known as social navigation, this enables users to build on the work of previous users, for example by seeing collective annotations, the most commonly selected data points, and the most popular locations on the visual space. However, while web-based visualizations by definition are distributed using a web server, most do not maintain the server-side database connections and aggregation mechanisms to achieve this. To bridge this gap between social navigation, its evaluation and visualization, we present Crowdster, a framework that supports capturing, aggregating, and visualizing user interaction data. We give three examples to showcase the Crowdster framework: a Google Maps app that shows the navigation trails of previous users, a scatterplot matrix that visualizes a density distribution of the most selected data points, and a node-link visualization that supports collective graph layout.","PeriodicalId":179584,"journal":{"name":"Proceedings of the Fifth Workshop on Beyond Time and Errors: Novel Evaluation Methods for Visualization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121223425","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, due to the complex spatio-temporal nature of gaze data for dynamic stimuli, there has been a need and recent trend toward the development of visualization and visual analytics techniques for such data. With this paper, we provide benchmark data to test visualization and visual analytics methods, but also other analysis techniques for gaze processing. In particular, for eye tracking data from video stimuli, existing datasets often provide few information about recorded eye movement patterns and, therefore, are not comprehensive enough to allow for a faithful assessment of the analysis methods. Our benchmark data consists of three ingredients: the dynamic stimuli in the form of video, the eye tracking data, and annotated areas of interest. We designed the video stimuli and the tasks for the participants of the eye tracking experiments in a way to trigger typical viewing patterns, including attentional synchrony, smooth pursuit, and switching of the focus of attention. In total, we created 11 videos with eye tracking data acquired from 25 participants.","PeriodicalId":179584,"journal":{"name":"Proceedings of the Fifth Workshop on Beyond Time and Errors: Novel Evaluation Methods for Visualization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122958618","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}
