We research haptics, robotics, and interactive technologies.

Inspired by capabilities of humans and other animals, we design haptic devices, create soft or wearable robots, investigate new material technologies, advance applications in VR and health, and explore mechanisms of perception and action.

The lab is directed by Prof. Yon Visell, whose interdisciplinary research spans several fields, including robotics, acoustics, soft electronics, and haptics. He previously served as General Co-Chair for IEEE Haptics Symposium 2020 and 2022, which were meetings of the longest running conference series in the field of haptics. Visell has held positions at UCSB, and several other science, art, and engineering entities in North America and Europe. More about Visell in his bio…

Our lab includes an inspiring group of engineers, artists, and scientists. It is part of the Media Arts and Technology Program, Departments of Electrical and Computer Engineering and Mechanical Engineering at UCSB. We are based in the California NanoSystems Institute, affiliated with the Communication and Signal Processing group in the Department of ECE and with the Dynamic Systems, Control, and Robotics in the Department of ME. The lab is affiliated with the Center for Polymers and Organic Solids, the UCSB Research Center for Virtual Environments and Behavior, and with the UCSB Robotics Group. The lab has received a half dozen awards, and many more nominations, for work presented in prominent academic venues.

News and Events

10.2024 Check out our preprint reporting a new tactile display driven by projected light [PDF]. The displays are fast and can scale to thousands of pixels, or large areas, cost-efficiently. They fast use photons rather than electrons, directly converting projected light into visible tactile patterns via a passive surface populated with arrays of millimeter scale optotactile pixels, yielding displacements up to 1 millimeter, response times of tens of milliseconds. Work from our lab, led by PhD student Max Linnander.

1.2024 Celebrating the publication of two more works from our group. Our article, Interpersonal Transmission of Vibrotactile Feedback via Smart Bracelets: Mechanics and Perception, was recently published at IEEE Transactions on Haptics. It was authored by Taku Hachisu, Gregory Reardon, Yitian Shao, Kenji Suzuki, and Yon Visell. Another new paper, SkinSource: A Data-Driven Toolbox for Predicting Touch-Elicited Vibrations in the Upper Limb, with authors Neeli Tummala, Greg Reardon, Simone Fani, Dustin Goetz, Matteo Bianchi (Univ. Pisa), and Yon Visell, reports a new toolbox and dataset simulating upper limb tactile biomechanics for haptics, neuroscience, and biomechanics. It was accepted for the Proceedings of IEEE Haptics Symposium 2024.
