The paper aims to explore the research method of multimodal interaction design based on the concept of bionics. From the perspective of bionics, this paper studied the biological control and coupling principle, compared the coupling element, coupling and modal, multimodal interaction, and studied the bionic coupling relationship. Based on the separate test method, individual removal method and analytic hierarchy process in the analysis method, the multimodal interaction design method was studied. It is found that the coupling of the bionic "coupler" is related to the "modal" of multimodal interaction. Both need to go through the process of input, processing and output, and both pay attention to maximized efficiency. A multi-modal design research model for execution flow is derived for the coupled element analysis method. The process mainly includes clear objectives, analysis modalities, categorization, sorting tests, modal design, refinement variables, correlation logic, model making, and test verification. With interactive product on child sexual assault education as an example, this method is practiced and demonstrated, which provides a new idea for multimodal interaction design. |
