3. Aim of the project

4. Typical characteristic:life-likeness, realism, epistemics

6. Control variables Aesthetics Relevance Similarity Experiment 1 Involvement Epistemics Distance Valence Task performance

7. Manipulations experiment 1 • Epistemics Realistic vs Unrealistic vs Unembodied Demonstration • Valence

9. Preliminary conclusions • Epistemics effects involvement, not distance • Valence effects distance, not involvement • Relevance and Aesthetics are important factors as well!

10. Task performance F(1, 128) = 4.48, p < .036 Preliminary conclusion: Valence effects task performance, Epistemics does not

11. Potentials for action Action

12. Experiment 2 • Are the Engagement and Interaction process dependent on each other?

14. Manipulations(pilot tests conduced soon) • Aesthetics: ugly versus beautiful • Affordances: aids versus obstacles

15. Measures • Involvement and distance • Intentions to use and Intentions not to use • Satisfaction • Task performance
