Abstract: To realize the accurate description for natural hand gestures and its intention,and to achieve the natural and efficient factory layout design under large space augmented reality,a novel interactive semantic model based on data glove and magnetic trackers was proposed.The ideas of Turing machine was used for reference in model design,and the model was divided into three layers:physical layer,lexical layer and syntax layer.Physical layer was used to get hand information (included hand gesture,gesture sequence and hand motion trajectory) collected by data glove and magnetic trackers.Lexical layer was composed by basic hand gestures'information.Syntax layer was a logical reasoning layer used to mapping hand gesture information to specific operations.The proposed model laid a foundation for implementing operations (included add virtual model,move model,rotate model,delete model,et al) used in layout design based on real workshop environment.A prototype system was developed to verify the effectiveness of the proposed model.
