Multisensory data sensualization based on human perception

A multisensory data sensualization environment was developed in which visual, acoustic, and touch sensation information could be used to display scientific data applying virtual reality technology. Specifically, a wind sensation display prototype using air flow pressure was developed to generate touch sensation. In scientific visualization, it is necessary to consider the characteristic of human perception in order to transmit data from the computer to the user accurately. The paper describes the scaling method of the sense displays based on psychological magnitude. Based on the experiment on sensory interference in perceiving data, the paper also proposes guidelines for the usage of multisensory information.
