Abstract

The invention discloses a virtual experiment system and method based on multi-modal interaction. The experiment system mainly comprises an input layer, a sensing and recognition layer, a fusion layerand an application layer. The method comprises the steps: acquiring corresponding visual information, sensing signals and voice signals through a visual channel, a tactile channel and an auditory channel respectively; respectively identifying the information of different channels; fusing corresponding vector sets constructed by modal information of the visual channel, the tactile channel and the auditory channel on the AR platform by adopting a multi-modal fusion method based on a decision level according to an identification result; and according to the fusion result, presenting an experimentprocess and an experiment result by adopting voice navigation, visual display and tactile feedback modes. Through the application, multiple channels can be fully utilized, and an experimental processis achieved by adopting a multi-mode fusion method, so that the operation load of a user is reduced, the immersion of an experiment is improved, and the efficiency of virtual interaction is improved.

Description

technical field [0001] The present application relates to the field of virtual experiment technology, in particular to a virtual experiment system and method based on multimodal interaction.
