Study design is critical in Human-Robot Interaction (HRI) due to its highly interdisciplinary nature, that spans a wide range of domains and often presents significant hurdles for novice researchers. Building on the success of the previous years, the fourth edition of the “Workshop Your Study Design” addresses this challenge by pairing early-stage researchers with experienced mentors to refine their study designs and offering mentor-led talks on key HRI topics, tailored to this year's conference sustainability theme. Participants are invited to submit a 2–4 page study proposal focusing on methodology and data analysis. Accepted submissions are discussed in small mentor-led groups, where participants receive targeted feedback on their study designs and can also benefit from engaging in discussions about other participants' submissions. Our expert mentors this year bring expertise in areas such as participatory design, qualitative analysis and longitudinal studies. Thus, the workshop aims to foster a collaborative environment where participants can not only strengthen their study designs, but also gain valuable insights and build lasting connections within the HRI community.

Humanoid social robots need to be able to move expressively. Traditional manipulation-focused teleoperation systems primarily control the end-effector's position and orientation, neglecting the extra degrees of freedom in human and robotic arms, which can lead to unnatural movements. This demonstration presents our Optimization-based Customizable Retargeting Algorithm (OCRA), designed for real-time motion mapping between dissimilar kinematic chains. OCRA functions well with widely varying robot-arm joint configurations. The presenter will use a commercial motion-capture suit to teleoperate the upper body of a NAO humanoid robot, demonstrating OCRA's ability to create intuitive, human-like movements in real time.

HRI is an interdisciplinary field that requires researchers to be knowledgeable in broad areas ranging from social sciences to engineering. Study design is a multifaceted aspect of HRI that is hard to develop and perfect. Thus, the second edition of the “Workshop Your Study Design” workshop aims to improve the quality of future HRI studies by training researchers and boosting the accessibility of HRI as a field. Participants will have the opportunity to receive guidance and feedback on their study from an expert mentor. Researchers from all avenues of HRI will be invited to submit a 2–4 page paper on an HRI study they are currently designing, including a brief introduction and a complete methods section. Accepted submissions will be discussed in small groups led by mentors with relevant expertise. Prior to the workshop, papers will be shared within each group. Participants will be encouraged to read other submissions. During the workshop, attendees will work within their menteementor groups to discuss each paper and provide feedback. There will also be a session where mentors lead mini discussions on topics important to study design, such as balancing qualitative and quantitative design, power analysis, and research ethics. The workshop will end with a session where all participants can share important lessons that they learned with fellow attendees.

Robots hold great potential for supporting exercise and physical therapy, but such systems are often cumbersome to set up and require expert supervision. We aim to solve these concerns by combining Captury Live, a real-time markerless motion-capture system, with a Rethink Robotics Baxter Research Robot to create the Robot Interaction Studio. We evaluated this platform for unsupervised human-robot interaction (HRI) through a 75-minute-long user study with seven adults who were given minimal instructions and no feedback about their actions. The robot used sounds, facial expressions, facial colors, head motions, and arm motions to sequentially present three categories of cues in randomized order while constantly rotating its face screen to look at the user. Analysis of the captured user motions shows that the cue type significantly affected the distance subjects traveled and the amount of time they spent within the robot’s reachable workspace, in alignment with the design of the cues. Heat map visualizations of the recorded user hand positions confirm that users tended to mimic the robot’s arm poses. Despite some initial frustration, taking part in this study did not significantly change user opinions of the robot. We reflect on the advantages of the proposed approach to unsupervised HRI as well as the limitations and possible future extensions of our system.

We live in an aging society; social-physical human-robot interaction has the potential to keep our older adults healthy by motivating them to exercise. After summarizing prior work, this paper proposes a tool that can be used to design exercise and therapy interactions to be performed by an upper-body humanoid robot. The interaction design tool comprises a teleoperation system that transmits the operator's arm motions, head motions and facial expression along with an interface to monitor and assess the motion of the user interacting with the robot. We plan to use this platform to create dynamic and intuitive exercise interactions.
