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.
