Findings on Robotic Hugging

In the first part of the HUGGIE project initiated by Oliver Bendel, two students of the School of Business FHNW conducted an online survey with almost 300 participants. In the management summary of their bachelor thesis Ümmühan Korucu and Leonie Stocker (formerly Leonie Brogle) write: “The results of the survey indicated that people have a positive attitude towards robots in general as robots are perceived as interesting and useful rather than unnecessary and disturbing. However, only a minority of the participants stated that they would accept a hug from a robot. A possible reason for this could be that for the majority of participants, a hug is an act of intimacy with a deeper meaning attached to it which is only being shared with selected persons. For a robot to be perceived as an attractive hugging partner, a human-like design including a face, eyes, a friendly look as well as the ability to communicate verbally and non-verbally is desired. However, an appearance being too realistic has a deterrent effect. Furthermore, an in-depth analysis of the data in relation to age and gender of the participants resulted in the discovery of interesting facts and differences. Overall, the findings contribute to a clearer picture about the appearance and the features Huggie should have in order to be accepted as a hugging counterpart.” The bachelor thesis will be publicly available in autumn 2020. There will also be a paper with the results next year.

Chocolate Could Increase Acceptance

A multi-stage HUGGIE project is currently underway at the School of Business FHNW under the supervision of Prof. Dr. Oliver Bendel. Ümmühan Korucu and Leonie Stocker (formerly Leonie Brogle) started with an online survey. The aim was to gain insights into how people of all ages and sexes judge a hug by a robot. In crises and catastrophes involving prolonged isolation, such as the COVID 19 pandemic, proxy hugs of this kind could well play a role. Prisons and longer journeys through space are also possible fields of applications. Nearly 300 people took part in the online survey. The evaluation is almost complete and the results are remarkable. Among other things, it was found that women want to be hugged by a robot that is bigger than them, and men want to be hugged by a robot that is smaller than them. Not only the size is relevant for the acceptance of robotic hugging: “An interesting input given by one of the participants was that it could be more pleasant to hug a robot if it smelled nicely, for example like chocolate.” (Draft of Bachelor Thesis) Whether this is a typically Swiss view remains to be investigated. The results of the survey and the conclusions drawn from them for the design of HUGGIE will be compiled in a paper in the course of the year.
