情感决策的智能家居虚拟人路径规划

Using affective decision-making for the path planning of virtual humans in a smart home

智能家居环境中的虚拟人,目前在智能性和行为规划的研究中还存在许多不足,针对这2方面问题,提出了认知过滤层的概念,并建立了虚拟人行为模型.在此基础上,对模型中的认知行为部分进行了深入研究,并利用现有情感模型将情感智能与虚拟人行为规划相结合.由于路径规划是一种基本且重要的行为,针对智能家居环境中多环形障碍物的特点,对路径规划算法进行了改进.通过三维仿真对上述模型和算法加以实现.仿真结果表明,虚拟人的行为具有一定的智能性,情感的加入也使得虚拟人更加人性化.

For virtual humans in a smart home,there are still many problems that must be solved before levels of apparent intelligence and social behavior are acceptable. To promote solutions,a cognition filtering layer was proposed and a behavioral model for virtual humans was established. Then,further study on cognition was performed,with current emotion models employed to study both emotional intelligence and behavioral planning of virtual humans. To deal with the many circular obstacles in a smart home,improvements to path planning were proposed. Finally,a 3-D simulation was used to test the proposed model and algorithm. Results showed that the behavior of virtual humans seemed more intelligent,while the inclusion of emotion made the virtual humans seem more humanized.
