Multidimensional scalar fields data analysis by means of multisensory visualization

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. We discuss in this article multisensory scientific visualization, in other words scientific visualization extended with sound, haptic and other sensory stimuli, related fields and concepts such as visualization, sonification and perceptualization, and geometric modeling using real functions. The formalization of the multisensory analysis process and particularly of establishing correspondences between the initial data and multiple sensory stimuli is an open research question. In this article, some generalizations based on using real-valued vector functions for solving data analysis problems by means of perceptualization are proposed. A more particular case study of a scalar field analysis using scientific visualization extended with such sensory stimuli like sound is considered.
