In this paper we investigate the use of a social robot as an interface for providing personalized information about nutrition.

The proposed approach is based on soft biometrics and it can estimate several traits simultaneously, such as gender and age of people in the field of view of the robot. Our hypothesis is that adding this capability to a social robot improves the persuasive effects, in terms of perceived informational quality, motivational strength and social believability, and the recall of the message.

Abstract
In this paper we investigate the use of a social robot as an interface for providing personalized information about nutrition. In particular, we evaluated the effect of message adaptation to some demographic traits that are automatically recognized by a social robot, Pepper in this case. The proposed approach is based on soft biometrics and it can estimate several traits simultaneously, such as gender and age of people in the field of view of the robot. Our hypothesis is that adding this capability to a social robot improves the persuasive effects, in terms of perceived informational quality, motivational strength and social believability, and the recall of the message. We performed a preliminary experimental study and its results seem to support the persuasiveness of the personalized nutritional coachI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
