There have been decades of research on the usability and educational value of augmented reality. However, less is known about how augmented reality affects social interactions. The current paper presents three studies that test the social psychological effects of augmented reality. Study 1 examined participants’ task performance in the presence of embodied agents and replicated the typical pattern of social facilitation and inhibition. Participants performed a simple task better, but a hard task worse, in the presence of an agent compared to when participants complete the tasks alone. Study 2 examined nonverbal behavior. Participants met an agent sitting in one of two chairs and were asked to choose one of the chairs to sit on. Participants wearing the headset never sat directly on the agent when given the choice of two seats, and while approaching, most of the participants chose the rotation direction to avoid turning their heads away from the agent. A separate group of participants chose a seat after removing the augmented reality headset, and the majority still avoided the seat previously occupied by the agent. Study 3 examined the social costs of using an augmented reality headset with others who are not using a headset. Participants talked in dyads, and augmented reality users reported less social connection to their partner compared to those not using augmented reality. Overall, these studies provide evidence suggesting that task performance, nonverbal behavior, and social connectedness are significantly affected by the presence or absence of virtual content.
Virtual reality (VR) is a technology that is gaining traction in the consumer market. With it comes an unprecedented ability to track body motions. These body motions are diagnostic of personal identity, medical conditions, and mental states. Previous work has focused on the identifiability of body motions in idealized situations in which some action is chosen by the study designer. In contrast, our work tests the identifiability of users under typical VR viewing circumstances, with no specially designed identifying task. Out of a pool of 511 participants, the system identifies 95% of users correctly when trained on less than 5 min of tracking data per person. We argue these results show nonverbal data should be understood by the public and by researchers as personally identifying data.
Figure 1. Grabity is a novel, unified design based on the combination of vibrotactile feedback, uni-directional brakes, and asymmetric skin stretch. The gripper-style haptic device can simulate grasping motions with a real object (top), in Virtual Reality (bottom). Gravity provides vibrotactile feedback during contact, high stiffness force feedback during grasping, and weight force feedback during lifting.
Synchrony, the natural time-dependence of behavior in human interaction, is a pervasive feature of communication. However, most studies of synchrony have focused on dyadic interaction. In the current work, we explore synchrony in three-person teams using immersive virtual reality. Participants spent about two hours collaborating on four separate design tasks. The tracking data from the VR system allowed precise measurement of head and hand movements, facilitating calculation of synchrony. Results replicated previous work that found nonverbal synchrony in dyads in immersive VR. Moreover, we manipulated the context of the task environment, an informal garage or a traditional conference room. The environment for the task influenced synchrony, with higher levels occurring in the conference room than the garage. We also explored different methods of extending synchrony from dyads to triads, and explore the relationship of synchrony to turn taking and gaze. This paper provides theoretical insights about nonverbal synchrony and how design work functions in triads and provides suggestions for designers of VR to support good collaboration.
