1 Experimenting with iCat in an eldercare environment Marcel HeerinkInstituut voor Information Engineering - Hogeschool van AmsterdamUniversiteit van Amsterdam - Human Computer Systems & Intelligent Systemsco-researchers:Vanessa Evers, Bob Wielinga , Ben Krose
4 Research questionIs 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 QuestionnaireObservationsFunctional and conversational acceptanceField 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.

9 Questionnaire UTAUT + SA = social abilities (-) PE = performance expectancyEE = effort expectancySI = social influenceAT = attitude toward using technologySE = self-efficacyANX = anxietyITU = intention to use+ SA = social abilities (-)+ feeling comfortable talking to a robot (conversational acceptance)5 point scaleQuestions instead of statements

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