User intent for virtual environments

In the virtual environments, multimodal interaction not only makes the traditional event-driven system complicated but also increases the task of the users to handle the heavy loads of cognitive and operational complexity. The authors extracted users’ operation intents and used intents to trigger system state transition. This paper investigated establishing operators’ intent set and intent experiment in a virtual assembly system. By observing actual operation processes and analyzing the expression of intent, the authors constructed an intent-driven system. The research laid a solid foundation for capturing and reasoning intents. The comparison of experimental results show that the intents make the intent-driven system more efficient than the traditional event-driven system and they are able to express users’ ideas accurately.
