Abstract:
Objective In view of the complex and diverse types of forest management operations, this paper aims at solving the problems of poor interactivity, lack of natural and realistic interactive experience, and the difficulties to deal with frequent operations, and developing a set of interactive methods of forest management measures based on body action.
Method A forest simulation scene based on the immersive virtual reality and visual simulation system CAVE2 was constructed as the interactive object, the management measures with strong interaction on the user side such as logging, pruning and replanting were selected, the limb movements in the operation process of forest management measures were analyzed, and the relative distance and angle changes between the management tools and users in the simulation scene were mapped with the limb actions. The interaction model of body movement was constructed to realize the implementation of limb action control management measures and the simulation of forest management.
Result The interactive model of body movement constructed in this study was correctly mapped into forest management measures. The success rate of single operation was 86%, and the good rate of interactive evaluation was 91%. The combination of body movement and management tools facilitates the expansion of interactive demand of forest management simulation.
Conclusion The simulation of forest management operation based on body action interaction can visually and intuitively show the operation process of forest management measures, which is helpful for the user's to further understand the forest management and improve the level of forest management assistant decision.
