Emma Hwang, Billy Bai, and Mehmet Erdem (all Hospitality) have published their study titled 'Service robot technologies as social actors: a systematic review' in the Journal of Hospitality and Tourism Technology. The study aimed to explore service robotic technologies from a social actor’s perspective and examine the role of service robots in the service industry. The findings indicate that robotic technologies play a variety of functions as social actors, not just as practical instruments in the hospitality and tourism industry. The study provides valuable insights into human-robot interactions, facilitating a deeper understanding and enhancing the impact of collaboration on service delivery systems.
