HFI lab members present at IEEE Haptics Symposium, Chua and students win award
—
The Human Fusions Institute was well-represented at the recent International Electrical and Electronics Engineers Haptics Symposium. Case Western Reserve University Assistant Professor Zonghe Chua and his Ph.D. students Jiaji Su and Irene Bhunia received the Honorable Mention Technical Regular Paper Award. Other students and faculty from CWRU, Cleveland State University, and University of California, Los Angeles traveled to Reno, Nevada, to showcase their research to fellow engineers from North America, Europe, and Asia.
For their award-winning paper, Chua and his students designed a pneumatic fingertip suction-feedback system for telemanipulation and conducted a user study with two experiments involving ten participants. Their recognition at the symposium underscores the institute’s leadership in haptics research. Audience members showed particular interest in the group’s psychophysics-based analysis of user behavior. Su found the experience of running a study from start to finish valuable, which further demonstrates our team’s research capabilities.
Ph.D. student Laura McGann, who studies with HFI Director Dustin Tyler, presented a poster on the role of haptics in the lab’s fully wearable, immersive human-in-the-loop interface, in which participants use body movements to complete manipulation tasks with a virtual robot arm. So far, she has worked with 27 human participants. She was encouraged by the positive reception of her poster and the enthusiasm for her multi-metric, transdisciplinary approaches.
Another one of Dr. Tyler’s Ph.D. students, Rachel Jakes, presented a hands-on demonstration entitled “Stereo Neural Haptics: Unencumbered Audio-Tactile Congruency.” Her demonstration delivers two independent haptic signals on the same finger synchronized with stereo sound. “Using surface electrical nerve stimulation, proximal activation of the nerves in the finger elicits spatially distinct sensations referred toward the fingertip,” said Jakes. “This system provides dynamic spatial feedback and precise temporal and intensity modulation, critical features for immersive applications with synchronized multisensory inputs. Further, the ring interface design keeps the fingertip free, enabling users to interact with the local environment unencumbered while receiving haptic data in mixed reality applications.” She had long lines for the demo on both days, including groups from Apple, Meta, and Google, and received a very positive reception.
Ph.D. student Ju-Hung Chen and M.S. student Jacob Hyman represented Assistant Professor Alexis E. Block’s Social and Physical Human-Robot Interaction (SaPHaRI) Lab. Their poster, a collaboration with Chua, focused on the Social Touch Taxonomy, an eight-level hierarchical binary decision tree categorizing common human-to-human social physical interactions. The goal is to use this as a reference to develop a robotic system delivering realistic social touch. “We had a lot of positive reception to our poster, and many people seemed to be interested in our work,” said Hyman. “We also got a lot of useful comments about what we can improve in our research and our future paper.”
“I’m incredibly proud of Jacob and Ju-Hung for their work at the IEEE Haptics Symposium,” said Dr. Block. “Their social touch taxonomy addresses a fundamental gap in how we understand and design touch in human-robot interaction, and the strong engagement it received reflects the field’s need for this direction. It was especially exciting to present this as a collaboration with Dr. Chua, showcasing the kind of interdisciplinary work we’re building within HFI.”
UCLA Ph.D. student Ben Forbes enjoyed the opportunity to see his Ohio-based HFI counterparts at the conference. He presented his research protocol, “Towards Human-Centered Teleoperation Through Learning-based Shared Autonomy Control,” which centers on human experience in teleoperation. Forbes appreciated the feedback about ideas for shared autonomy algorithms. “People appreciated the way that our work focused on the human as opposed to robotic task performance,” he said. “I gained a lot of valuable perspectives from prominent figures in academia about where they think the field of haptics and tactile sensing is going. I learned a lot about measures of the human sense of touch and about ways to improve my research. I appreciated the perspectives of folks from industry.”
Cleveland State Ph.D. student Kelleigh Pettegrew shared the ways researchers describe and understand the experience of human-in-the-loop research. “Many people remarked that this was an interesting and understudied area of research, and that they would like to see follow-up work,” she said, while noting that she enjoyed learning about work being done on haptics to support rehabilitation and physical therapy while in Reno.
Also an HFI Ph.D. student from Cleveland State, Claire Foley focused on knowledge integration of transdisciplinary research teams. “I find that teams cycle through periods of structure, periods where norms and roles are defined, and anti-structure, periods where roles and norms are loosened,” she said. “I also find that moving through this dynamic is effortful, but requires less effort when all participants’ perspectives, knowledge, and experiences are valued as meaningful contributions to the work, regardless of discipline, role, or seniority. In many of my conversations, people expressed enthusiasm for HFI’s haptics research more broadly, both in its scope and approach. One person said, ‘It seems like this team is having fun while doing research.’ I told them that this was absolutely true.”
In addition to giving their own presentations, researchers had the opportunity to network with other engineers in the haptics field. “One of the most interesting things I learned (at the conference) was that the haptics field itself is still in its infancy, and there is a lot of interesting work going on right now as the field grows,” said Chen.
