  1. Agents with Character

  2. Agents with Character Evaluation of Empathic Agents in Digital Dossiers Johan F. Hoorn Anton Eliëns VU Amsterdam Zhisheng Huang Henriette C. van Vugt Elly A. Konijn Communication Science Cees T. Visser Artificial Intelligence Information Management & Software Engineering

  3. structure • introduction • user engagement with empathic agents • PEFiC in digital dossiers • evaluation scenarios • development of the MetaMorph box • interactive PEFiC powered by DLP/STEP • some issues and pitfalls • conclusions

  4. carry back home message • an empirically tested model of engaging fiction characters (PEFiC) • test scenarios in the real-life application domain of digital dossiers • DLP+X3D/STEP technology to support virtual environments and characters all the ingredients needed to conduct proper agent research

  5. user engagement with empathic agents face-to-face: task relevant information facilitation, motivation empathy? human experience with fictional characters appreciation :: involvement <> distance

  6. embodied agents as fictional characters PEFiC • phase 1 -- encoding • ethics -- good vs. bad • aesthetics -- beauty vs ugliness • epistemics -- realistic vs. unrealistic • phase 2 -- comparison • establishing personal relevance, mutual similarity and valence towards fictional character • phase 3 -- response • involvement vs distance -- tendency to approach or avoid

  7. PEFiC in digital dossiers

  8. evaluation scenarios ... • navigation -- pure interactivity • guided tours -- using some narrative structure • agent-mediated -- navigation and guided tours

  9. development of the MetaMorph box 64 systematically varied agent types ethics -- polite vs impolite task relevance --providing cues valence -- task assistance similarity -- relation to existing person aesthetics -- (cliché’s of) beauty epistemics --photorealism

  10. interactive PEFiC powered by DLP/STEP

  11. DLP/STEP programming platform • declarative language -- for agent support • multiple threads of control -- for multiple shared objects • distributed communication -- networking capabilities (TCP/IP) scripting behavior • convenience -- for non-professional authors • compositional semantics -- combining operations • re-definability -- for high-level specification of actions • parametrization -- for the adaptation of actions • interaction -- with a (virtual) environment

  12. agents in multi-user virtual environments • mixed-media presentations with commentators • Tai-Chi, domestic servants and conducting music DLP/STEP applications • tai-chi demonstrator • grasping and reaching, using inverse kinematics and reasoning • facial animation (with text-to-speech) • virtual presenter -- presenting powerpoint presentation

  13. some issues and pitfalls complexity of domain of cultural heritage limited number of experts with sufficient knowlegde example task: prepare an installation of a work of art in a museum we should restrict the user’s task to exploration or tasks requiring limited expertise

  14. conclusions we presented: • an empirically tested model of engaging fiction characters (PEFiC) • test scenarios in the real-life application domain of digital dossiers • DLP+X3D/STEP technology to support virtual environments and characters all the ingredients needed to conduct proper agent research
