摘要
首先以心理动力学中的心理能量概念为基础,分析了情感能量以及表示情感状态的相关参数.然后根据情感能量守恒定律,研究了情感能量分配结构的数学表示方法和情感能量分配模型,进一步分析了情绪状态的变化过程,提出了情绪状态刺激转移过程的隐马尔可夫链及其模型算法;利用MATLAB建立相关情感状态变化的仿真研究平台,进一步研究了情感状态的变化规律.最后根据以上情感模型及其变化规律构建出表情机器头的综合研究平台,仿真结果与机器头实验数据的一致,验证了仿真模型的有效性.
Emotional energy and related parameters describing emotional state were analyzed based on the psychological energy of psycho-dynamics. An emotional energy distributing configuration model and an emotional state probability description space were studied according to the energy balance law. The hidden Markov chain algorithm of excitation transition process was implemented to specify emotional state transferring process. By means of MATLAB simulation, the changing law of emotional state was further stud- ied. Finally, a comprehensive research platform of emotional robot heads was built. It was also found that the results simulated by the emotional energy model were in perfect agreement with the experimental ones of an emotional robot head, demonstrating the validity of the model.
