Human make behavior by perception, modeling believable perception for a virtual agent is a meaningful topic in computer games. A model of adaptive perception of a virtual agent with emotion is proposed based on Q-learning method; the formulas of emotion value are presented. A demo system is realized on PC; an agent with the model can dynamically control the range of the perception according to virtual...
Children like cartoon games, a cartoon game for children should support more knowledge. Leaning nonverbal emotion interaction is a very important social skill for a child, how to animate nonverbal emotion interaction in a cartoon game is an interesting subject. Emotion cognitive structure of a virtual character is presented, emotion expression method is also proposed, a virtual character can express...
In video games, it's very important to model a virtual agent with motivation variables. In previous researches, a virtual agent's motivation variables are always static. An evolvable motivation system for a virtual agent is set up, priority sequence of an agent's behaviors is decided by the priority sequence of its motivations, the priority sequences of an agent's motivations are determined by genetic...
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...
Emotion models for virtual human are playing important roles in modern computer games, intelligent virtual humans should behave human-like emotions. How to calculate emotion intensity is a very meaningful subject in the domain of emotion research. A cognitive architecture of virtual human is presented by psychology and neural science, it includes perception, emotion, mood, personality, motivation...
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...
