The Influence of Perspective on Training Effects in Virtual Reality Public Speaking Training

2022 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW) (2024)

Fumitaka Ueda Yuichiro Fujimoto Taishi Sawabe Masayuki Kanbara Hirokazu Kato

A third-person perspective in virtual reality (VR) based public speaking training enables trainees to observe themselves through self-avatars, potentially enhancing their public speaking skills. This study investigates the influence of perspective on the training effects, specifically changes in public speaking skills through training. In the experiment, VR job interview training was conducted for five days under three perspective conditions. Mock interviews were also performed before and after training, and were assessed by external raters. The results revealed that the training effects were significantly higher in the Front condition concerning verbal communication skills and the overall impression of the interview.

Vision-based registration for augmented reality system using monocular and binocular vision

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2003)

Steve Vallerand Masayuki Kanbara Naokazu Yokoya

In vision-based augmented reality systems, the relation between the real and virtual worlds needs to be estimated to perform the registration of virtual objects. This paper suggests a vision-based registration method for video see-through augmented reality systems using binocular cameras which increases the quality of the registration performed using three points of a known marker. The originality of this work is the use of both monocular vision-based and stereoscopic vision-based techniques in order to complete the registration. Also, a method that performs a correction of the 2D positions in the images of the marker points is proposed. The correction improves the registration stability and accuracy of the system. The stability of the registration obtained with the proposed registration method combined or not with the correction method is compared to the registration obtained with standard stereoscopic registration.

Investigating the Efficacy of Pain Relief Through a Robot's Stroking with Speech

Kota Nieda Taishi Sawabe Masayuki Kanbara Yuichiro Fujimoto Hirokazu Kato

"Stroking" is generally recognized to contribute to pain relief. Recent research indicates that combining "stroking with speech" by a robot generates greater positive emotions in individuals than either "speech" or "stroking" only. It has also been known that positive emotions can mitigate the perception of pain. This study aimed to verify whether the action of "stroking with speech" by a robot can reduce pain. We established two hypotheses: 1. Based on the gate control theory, the action of "stroking" with tactile stimulation and "stroking with speech" have pain-relieving effects. 2. The action of "stroking with speech," which has a greater psychological impact than "stroking," has a more significant pain-relieving effect. Through experiments with 37 subjects, these two hypotheses were supported.

Vocal Synchrony of Robots Boosts Positive Affective Empathy

Applied Sciences (2021)

Shogo Nishimura Takuya Nakamura Wataru Sato Masayuki Kanbara Yuichiro Fujimoto

Robots that can talk with humans play increasingly important roles in society. However, current conversation robots remain unskilled at eliciting empathic feelings in humans. To address this problem, we used a robot that speaks in a voice synchronized with human vocal prosody. We conducted an experiment in which human participants held positive conversations with the robot by reading scenarios under conditions with and without vocal synchronization. We assessed seven subjective responses related to affective empathy (e.g., emotional connection) and measured the physiological emotional responses using facial electromyography from the corrugator supercilii and zygomatic major muscles as well as the skin conductance level. The subjective ratings consistently revealed heightened empathic responses to the robot in the synchronization condition compared with that under the de-synchronizing condition. The physiological signals showed that more positive and stronger emotional arousal responses to the robot with synchronization. These findings suggest that robots that are able to vocally synchronize with humans can elicit empathic emotional responses.
