1Experimenting 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
4Research questionIs there a measurable influence of perceived social abilities on the acceptance of autonomous interactive systems by elders in an eldercare environment?
5Approach Quantitative research iCat Wizard of Oz +S and –S version QuestionnaireObservationsFunctional and conversational acceptanceField experiment: 2 eldercare institutions (Archipel and Ankerplaats)
6Abilities 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.
9Questionnaire 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

21Conclusions & 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
