We propose an integrated framework in which local perception and close manipulation skills are used in conjunction with a high-level behavioral interface based on a "smart object" paradigm as support for a virtual agent to perform autonomous tasks. In our model, virtual "smart objects" encapsulate information about possible interactions between the agent and its environment, including sub-tasks defined by scripts that the agent can perform. We use the information provided by low-level sensing mechanisms to construct a set of local, perceptual features, with which to categorize at run-time possible target objects. Once objects are activated, based on their interactivity information and on the current task script, the agent can reparametrize its behavior, according to its mission goal defined in a global plan script. A challenging problem solved here is the construction (abstraction) of the mechanism to link individual perceptions to actions. As a practical result virtual agents are capable of acting with more autonomy, enhancing their performance
