A well-known definition of visualization is the mapping of initial data to a visual representation, which can be perceived and interpreted by humans. Human senses include not only vision, but also hearing, sense of touch, smell and others including their combinations. Visual analytics and its more general version that we call Multisensory Analytics are areas that consider visualization as one of its components. We present a particular case of the multisensory analytics with a hybrid visual-auditory representation of data to show how auditory display can be used in the context of data analysis. Some generalizations based on using real-valued vector functions for solving data analysis problems by means of multisensory analytics are proposed. These generalizations might be considered as a first step to formalization of the correspondence between the initial data and various sensory stimuli. An illustration of our approach with a case study of analysis of a scalar field using both visual and auditory data representations is given.

The article discusses visual analytics, which, according to J. Thomas, is understood as the solution of problems of data analysis using a facilitating interactive visual interface. Today, visual analytics is widely used in various fields -in research, design, management and others, due to the well-known predisposition of people to spatial thinking. Despite the wide usage, according to the authors, the theoretical aspects of visual analytics are not well developed at present, which is certainly a limiting factor in the development of visual analytics tools and its effective use in practice. It is declared in the article, that one of the most common of the forms of visual analytics is solution of data analysis problems using the visualization method. The visualization method is described in details and a number of works done by the "Scientific Visualization" laboratory NRNU MEPhI in this area are presented as an example of usage of the visualization method. The works were performed in different subject areas from physics to finance and monitoring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
