Information visualization techniques have been successfully used to build visual and interactive analysis of data and data relationships. However, dimensionality, volume and diversity make it difficult for a single technique to completely solve the problem. Information visualization tools that support multiple coordinated views allow the user to better(More)
This paper presents a prototype for information visualization in an Augmented Reality environment. The prototype allows users to perform common tasks in desktop information visualization tools, such as data dynamic filters, attribute selection, semantic zoom and details on demand. Such tasks are seldom available in AR environments. We used a customized(More)
Information Visualization techniques have been successfully used to build visual and interactive analysis of data and data relationships. One of its possible areas of application is computer network monitoring and traffic analysis. The analysis of the internal behavior of a company with high demand for Internet services helps to determine if the company is(More)
This paper presents a data analysis tool for mobile devices. Coordinated views are used to enhance the user's perception over data and diminish the difficulties caused by the lack of resources these mobiles present, specially when it comes to display size. The tool was totally developed in JavaME, what guarantees portability, scalability and code reuse. It(More)
Many information visualization techniques and tools have been created to analyze and understand temporal data. However, it is noticeable that time dimension is underused in most techniques and tools, used only as an aid in the search for patterns and answers. Therefore, this paper proposes an adaptation of the treemap joined with the calendar metaphor,(More)
This paper proposes the use of multiple coordinated views to support visual analytics. The Information Visualization tool PRISMA includes the implementation of three coordinated visualization techniques (treemap, parallel coordinates and scatterplot) and other auxiliary charts. The coordination is supported by filter, brushing, visual representation and(More)
Nowadays, workflow in various scenarios requires teamwork and collaboration. There is no doubt that working in teams and cooperate together provides a way to get better results in a short period of time compared to a single person job. With the large output of data, Information Visualization have become an important area to organize and assist decision(More)

The goal of this paper is to present an information visualization application capable of opening and coordinating information over two or more datasets. We have chosen this approach to address some of the limitations of various applications. Also, the application uses multiple coordinated views and multiple simultaneous datasets. We highlight the(More)
This paper presents a starting study on InfoVis interaction through mid-air gestures, using a vision based interaction device, the Leap Motion. We present the user tests conducted and the results gathered, using a 3D Scatterplot as visualization technique. These tests aim in identify and categorize issues that can compromise InfoVis mid-air gestural(More)
