Several applications, in several areas of human activity, treat data obtained from sampling, using different sensors, or produce them through the execution of computational processes. In addition, the availability of such data more broadly as a result of the diffusion of information and communication technologies has dramatically increased the amount of data available. Visualization of data and information is focused on helping to explore and accelerate the understanding of data through interactive tools that explore the capacity of the human perceptual system. The central challenge in terms of design is to produce the mapping in a cognitively useful way while taking advantage of the current interaction technology to allow the user to explore the information space and eventually change the mapping parameters. In addition to the visualization and interaction aspects, the aggregation of data analysis methods is essential so that users can migrate from visual exploration to hypothesis analysis and testing in an integrated way. The present proposal has as general objectives: (1) investigation of techniques of visualization and analysis of volumetric data and (2) investigation of techniques of interactive visualization and analysis of information.
