Abstract
: : Emulation of Emotion Using Vision with Learning
Theorists claim that to implement emotional behavior in an artificial agent it is necessary to continually and
concurrently evaluate sensor inputs and their associated behaviors. This has been facilitated by recent
developments in the architectures and frameworks used with embodied and situated autonomous agents.
When vision which uses learning is added, the emulation of emotion in an artificial agent is further enhanced.
Action Selection Dynamics (ASD) or Behavior Network, proposed by Pattie Maes of the Massachusetts
Institute of Technology (MIT), provides Subsumption Architecture (SA), proposed and developed by Rodney
Brooks also of MIT, with additional flexibility in coordinating behavior activation in a fully distributed manner.
The agent can effectively monitor the environment and adapt to changes as they occur rather than the human
observer having to manually adjust the priority structure that governs behavior action. The addition of vision
to this framework provides an additional sensory input so that the SA robot with ASD is further aware of its
environment at all times. The vision system was designed and implemented based on the behavior-based
vision methodology of Ian Horswill of MIT. With the vision added, the robot can respond to minute changes in
the environment, which other sensors are not capable of detecting. While at the same time it enhances the
area of the environment that is monitored. This makes the interaction between the robot and human
considerably richer. Responses by the robot are based on comments the robot receives from a human
interrogator. The robot's response to its environment is unique each time it is run, an important consideration
when emulating human-like emotions. Further interaction with humans in the environment is provided with the
addition of speech recognition/synthesis capabilities to the robot. Furthermore, the robot will not only
demonstrate human-like emotions through its behaviors but with the addition of the speech it can also
vocalize those emotions.
