  1. Experimenting with iCat in an eldercare environment Marcel Heerink Instituut voor Information Engineering - Hogeschool van Amsterdam Universiteit van Amsterdam - Human Computer Systems & Intelligent Systems co-researchers: Vanessa Evers, Bob Wielinga , Ben Krose

  2. Background 2000 2025

  3. Robots & eldercare • Paro • Pearl • Aibo

  4. Research question • Is there a measurable influence of perceived social abilities on the acceptance of autonomous interactive systems by elders in an eldercare environment?

  5. Approach • Quantitative research • iCat • Wizard of Oz • +S and –S version • Questionnaire • Observations • Functional and conversational acceptance • Field experiment: 2 eldercare institutions (Archipel and Ankerplaats)

  6. Abilities • listening attentively (looking at the participant, nodding), • being nice and pleasant to interact with (smiling, being helpful), • remembering little personal details about people (using their names), • being expressive, • admitting mistakes.

  7. Conditions

  8. Possible functionalities • Agenda/reminder • Device interface • Monitor • Companion

  9. Questionnaire • UTAUT • PE = performance expectancy • EE = effort expectancy • SI = social influence • AT = attitude toward using technology • SE = self-efficacy • ANX = anxiety • ITU = intention to use • + SA = social abilities (-) • + feeling comfortable talking to a robot (conversational acceptance) • 5 point scale • Questions instead of statements

  10. Results 1

  11. Results 2 Did you feel uncomfortable talking to a robot?

  12. Results 3 Would you want to use the iCat immediately if you could?

  13. Observations

  14. Observations 2

  15. Movie • Start

  16. Conclusions & discussion • UTAUT constructs show no significant differences between more en less social condition • There are significant differences concerning “conversational acceptance”: participants felt more uncomfortable and used more conversational expressions with a more social robot • Other differences are related to gender (could be a generation related result) • Further research: • On screen agents • Different experimental conditions? • Work on ‘social abilities?’ • More elaborate observation model
