Abstract
Vi undersøgte, om simple tidslige signaler i lyd (chronemics, altså tidens rolle i kommunikation) kan få folk til at have større tillid til en indkøbsassistent-robot og opnå mere bæredygtige resultater. Vi brugte to fyldlyde: et kort "Hmm" og et lille stykke musik, der minder om elevatormusik. Lydene blev brugt som faste fyldpauser i en monokron tidsmodel, hvor handlinger foregår én ad gangen. Derudover trak designet på ikke-verbale koder, passende afstande i interaktionen (interaction zones) og lydlige aspekter som en fornemmelse af rum og fiktion. Sammenlignet med udgangspunktet steg tillidsscorerne med 20-23 %, og de bæredygtige resultater fordobledes (100 % stigning). I fremtidigt arbejde bør robotten styres af kode i stedet for Wizard-of-Oz-metoden (en skjult menneskelig operatør), og forklaringerne om bæredygtighed for hver vare bør uddybes.
We examined whether simple timing cues in sound (chronemics, the role of time in communication) can help people trust a shopping-assistant robot and achieve more sustainable outcomes. We used two fillers: a brief "Hmm" and a short musical clip similar to elevator music. These were static fillers used as fixed pauses within a monochronic time model, where actions happen one at a time. The design also drew on nonverbal codes, appropriate interaction distances (interaction zones), and auditory aspects such as a sense of space and fiction. Compared with a baseline, trust scores increased by 20-23%, and sustainable outcomes doubled (a 100% increase). Future work should run the robot via code rather than the Wizard-of-Oz method (a hidden human operator) and provide clearer sustainability explanations for each shopping item.
