Since the differences of individual pedestrians and the diversity of pedestrian‐vehicle avoidance behaviors in real life, it is important to consider the behavioral heterogeneity of pedestrians and vehicles in simulation. Most existing simulation models cannot generate personalized pedestrian‐vehicle avoidance scenarios. Taking personality and emotional factors into account, we proposed a simulation...
With the coming of information age and the extensive application of virtual reality technology, there is a growing concern to e-learning. In the field of virtual reality technology, 3D e-learning for children is becoming a hot topic. In recent years, traffic accidents occur frequently in China, causing a large number of casualties and property losses. Because of children's special characteristics,...
In modern computer games, a NPC (non-player character) can make choices. In the previous researches, a NPC can have the certain knowledge in a game world; this will reduce the believability of perception for a NPC. A decision model based on Bayesian network and fuzzy logic for a NPC is set up in this paper; a NPC can partially know domain knowledge. A behavior animation of a virtual dog by the model...
A model for studying the impacts caused by emotions of individual agents in a crowd is presented, the model is based on the crowd model proposed by helbing, every agent can have emotion and motivation attributes, the behaviors of different agents are set up by a function with individual parameters. The method of an individual's joining a crowd is proposed, and reactive mechanism between crowds is...
In order to enhance the educational function of children traffic safety education software, a task-independent, 3D animated virtual tutor has been developed in editable virtual traffic environment. The details of system structure and virtual tutorpsilas modules are described to illustrate how the problem was solved and how the expandable capability was installed. Based on the models, real traffic...
Modeling intelligent virtual agent is a new research field that integrates artificial life and computer animation together. A believable virtual agent should have personality, motivation, and emotion. Personality is an important characteristic for a virtual agent, the relative researches on intelligent agents are summarized, and the formal definitions for personality and emotions are presented in...
Virtual characters are important components in modern computer games; intelligent virtual character is a new research field that integrates artificial life and computer animation together. A believable virtual character should not merely have behavior, emotion, but abundant personality even more. Personality is an important characteristic for virtual character, the current researches on computer personality...
Human's soul is very complex, it is related to stimulus and mental process. In this paper, a primary exploration for virtual human 's mental variables is presented, mental variables include emotion, motivation, and personality. For example, modeling emotion is an interesting topic in many fields. Emotion decision includes uncertain information, and grey number is suitable to express uncertain information...
Cartoon animation has already become the mainstream of propagating culture in the network at present. China has abundant ancient civilization, how to keep and propagate ancient civilization by cartoon animation has very important realistic meaning, "frog's sound in lotus pool" in Judge Dee's mystery is selected as primitive drama in this paper, the process of settling a lawsuit is expressed...
Simulation of pedestrians in computer animation is a challenging and interesting subject for many fields. A behavior animation model of pedestrians is presented in this paper. A virtual pedestrian is regarded as an agent with built-in cognitive model that integrates sense, perception, emotion, behavior, etc. together. Psychology-based navigation method is introduced in this paper by Gibson's theory...
