  1. Aesthetically EvolvedVirtual Pets Tom Ray Zoology, University of Oklahoma ATR Human Information Processing Research Laboratories, Kyoto

  2. The Concept • Aesthetic, emotional, and empathetic selection are applied to a derivative of Karl Sims'Evolved Virtual Creatures. • The resulting Creatures can be beautiful or strange, and provoke strong reactions in human observers. • It may be possible to evolve virtual pets to which humans can form strong emotional bonds.

  3. Directed Graph Bodies

  4. Neural Circuitry • Sensors • Processors • Effectors • Randomly Connected

  8. Ray’s Creatures

  9. Coming Enhancements • Genome editor • Hybrid GA / aesthetic selection • Co-evolutionary scenarios

  10. Sims’ Automated Evolution • Karl Sims used a GA to automate evolution • With selection for: • Swimming speed • Crawling/walking speed • Jumping height • Ability to follow

  11. Sims’ Co-evolution • Karl Sims used GA selection for possession of a block • to create a co-evolutionary scenario

  12. Ray’s Co-evolution • Rather than using GA selection for competition • I will evolve my creatures to love • By selecting for: • Moving towards one another • Maximum surface contact • Continued relative movement while in contact
