A Perception Framework for Intelligent Characters in Serious Games(Extended Abstract)

摘要

The use of BDI-agents seems a good fit to realize intelligent behavior for virtual humans. One of the problems of the BDI-paradigm when an agent becomes embodied in a virtual environment is the lack of control over perception [3]. While performing a task, humans tend to direct their attention to selected information from the environment which can support them in achieving the task. As attention is considered to be a limited resource, one cannot attend to all aspects in the environment which currently fall into sensory range. The same can be said for BDI-agents. Without any form of goal-directed perception, an agent can become flooded with sensory information from the virtual environment, which may result in reasoning over too much irrelevant information. Besides the risk of performance loss this is also unrealistic when we look at the physiology of human perception [1]. A balance must be found between stimulus-driven and goal-based control over perception.
