Real-Valued Sensory Readings

In addition, real-valued sensory readings (as opposed to binary predicates) have been used throughout the design of the behavior system. The particular form of sensory information passed from the perception to the behavior system affects how effectively the behavior system couples perception to action. We believe that real-valued sensory readings are more convenient to use especially when deriving motor control parameters for specifying continuous 3D actions. The convincing animation results we have been able to obtain demonstrates the success of using real-valued sensory information. Binary sensory readings may be sufficient for behavior arbitration in a virtual environment with modest complexity as is shown by Maes Maes91a. (For more details about Maes' implementation, see Appendix gif.) However, Maes' mechanism does not consider how a chosen behavior can be implemented, which disregards half of the action selection process.
