Interaction between hotel service robots and humans: A hotel-specific Service Robot Acceptance Model (sRAM)

Abstract The growing implementation of robotics in hospitality and tourism requires broader research into customers' experience with service robots. This study explores human-robot interaction (HRI) in the context of tourists interacting with hotel service robots. The data, 7994 online TripAdvisor reviews of 74 hotels, were subjected to a content analysis based on the Service Robot Acceptance Model (sRAM) and its dimensions (functional, social-emotional and relational). A sentiment analysis was also carried out. The results identify the principal dimensions and variables involved in HRI and the feelings robots inspire in different types of travellers. Guests most often comment on the functional dimension. Robots' functions determine this experience and influence the interaction between robots and hotel guests.
