“…While gender effects have been observed in previous work (see, for instance, [8], [9], [14] and [11]), we were nevertheless rather surprised concerning the extent to which men and women were found to differ in the current study. Moreover, the effects of the different intonation contours seem to be different for men and women; in particular, female participants responded significantly more positively to the rising intonation contours than male participants.…”

Abstract. In this paper, we address social effects of different mechanisms by means of which a robot can signal a person that it wants to pass. In the situation investigated, the robot attempts to pass by a busy, naïve participant who is blocking the way for the robot. The robot is a relatively large service robot, the Care-o-bot. Since speech melody has been found to fulfill social functions in human interactions, we investigate whether there is a difference in perceived politeness of the robot if the robot uses a beep sequence with rising versus with falling intonation, in comparison with no acoustic signal at all. The results of the experimental study (n=49) shows that approaching the person with a beep makes people more comfortable than without any sound, and that rising intonation contours make people feel more at ease than falling contours, especially women, who rate the robot that uses rising intonation contours as friendlier and warmer. The exact form of robot output thus matters.

“…The perception and expectations of the users were evaluated via questions in the closed questionnaire and in the interview. Inspired by [14], we focused on the communicative and cognitive capabilities of the agent. The participants were asked to reflect on whether they changed and if so, how they changed, their manner of speaking.…”

Abstract. We investigate the relationship between the embodiment of an artificial companion and user perception and interaction with it. In a Wizard of Oz study, 42 users interacted with one of two embodiments: a physical robot or a virtual agent on a screen through a role-play of secretarial tasks in an office, with the companion providing essential assistance. Findings showed that participants in both condition groups when given the choice would prefer to interact with the robot companion, mainly for its greater physical or social presence. Subjects also found the robot less annoying and talked to it more naturally. However, this preference for the robotic embodiment is not reflected in the users' actual rating of the companion or their interaction with it. We reflect on this contradiction and conclude that in a task-based context a user focuses much more on a companion's behaviour than its embodiment. This underlines the feasibility of our efforts in creating companions that migrate between embodiments while maintaining a consistent identity from the user's point of view.

“…In recent years, there have been various studies [8] [4] [5] [3] investigating the effect of a robot's appearance on the interaction with a user. However, most studies concerning the appearance of robots rather deal with the uncanny valley effect [2] and users' impression of robots than with the effect of a robot's appearance on its user's communicative behavior.…”

“…Kriz et al [8] investigated users' conceptualizations of robots by analyzing the way the users talked to the robot. They compared features of robot-directed speech to how humans talk to infants or adult non-native speakers.…”

Abstract-Our study compares users' interaction with a humanoid robot and a dog-shaped pet-robot. We conducted a user study in which the participants had to teach object names as well as simple commands to either the humanoid or the pet-robot and give feedback to the robot for correct and incorrect performance. While we found, that the way of uttering commands rather depends on personal preference than on the robots' appearance, the way of giving positive and negative feedback differed significantly between both robots: We found that for the pet-robot users gave reward in a similar way as giving reward to a real dog by touching it and commenting on its performance by uttering feedback like "well done" or "that was right". For the humanoid, users typically did not use touch as a reward and rather used personal expressions like "thank you" to praise the robot. Our findings suggest that users actually rely to some degree on the appearance of a robot as a cue for deciding how to interact with it.
