Humanoid coworkers: How is it like to work with a robot? Humanrobot interaction in corporate workplaces is a research area which remains unexplored. In this paper, we present the results and analysis of a social experiment we conducted by introducing a humanoid robot (Nadine) into a collaborative social workplace. The humanoidu0027s primary task was to function as a receptionist and provide general assistance to the customers. Moreover, the employees who interacted with Nadine were given over a month to get used to her capabilities, after which, the feedback was collected from the staff on the grounds of influence on productivity, affect experienced during interaction and their views on social robots assisting with regular tasks. Our results show that the usage of social robots for assisting with normal daytoday tasks is taken quite positively by the coworkers and that in the near future, more capable humanoid social robots can be used in workplaces for assisting with menial tasks. Finally, we posit that surveys such as ours could result in constructive opinions based on technological awareness, rather than opinions from mediadriven fears about the threats of technology.

xe2x80x9cYou Are Doing so Great!xe2x80x9d xe2x80x93 The Effect of a Robotxe2x80x99s Interaction Style on SelfEfficacy in HRI People form mental models about robotsxe2x80x99 behavior and intention as they interact with them. The aim of this paper is to evaluate the effect of different interaction styles on selfefficacy in humanrobot interaction (HRI), peoplexe2x80x99s perception of the robot, and task engagement. We conducted a user study in which a social robot assists people verbally while building a house of cards. Data from our experimental study revealed that people engaged longer in the task while interacting with a robot that provides person related feedback than with a robot that gives no person or task related feedback. Moreover, people interacting with a robot with a personoriented interaction style reported a higher selfefficacy in HRI, perceived higher agreeableness of the robot and found the interaction less frustrating, as compared to a robot with a taskoriented interaction style. This suggests that a robotxe2x80x99s interaction style can be considered as a key factor for increasing peoplexe2x80x99s perceived selfefficacy in HRI, which is essential for establishing trust and enabling Humanrobot collaboration.
