interface that touches us back

About Us

THIS IS A CHANGE We create haptic interfaces that enrich people’s lives.

What is Haptics? Simply put, it is sensing and manipulation through the sense of touch. Despite haptics research and technology development in the past 20+ years, most commercial systems are still stuck with a simple vibrational alert for feedback. We want to change that! We want to create nuanced and rich haptic sensations with existing and novel actuators.

Adding haptic feedback to the vast visual and audio information out there can only get us so far. Creating from the start an experience with haptics as an integral part is the way to go. We want a future where one will miss haptics if we take it away.

Hong Tan

Hong Z. Tan Founder & CEO

THIS IS A CHANGE Hong is a professor of Electrical and Computer Engineering at Purdue University, with courtesy appointments in Mechanical Engineering and Psychological Sciences. Hong has recently led haptics technology development and managed the Human Computer Interaction group at Microsoft Research Asia in Beijing, China. A veteran haptics researcher for over 20 years, Hong is best known for her work on haptics psychophysics, taking a human-centered approach to developing haptic interfaces that match our sensorimotor capabilities. Hong earned her B.S. in Biomedical Engineering from Shanghai Jiao Tong University, and S.M. and Ph.D. degrees tin Electrical Engineering and Computer Science from Massachusetts Institute of Technology.

Arnold Chen

Arnold Chen Advisor

Arnold’s expertise includes start-up companies (semiconductor hardware), culture, team building, manufacturing, and operations. Prior to joining the Purdue Foundry, Arnold spent the last 17 years at the epicenter of entrepreneurship, Silicon Valley, working at 3 different start-ups, one of which was acquired and one went IPO. Arnold is a Purdue alumus (BSEE’91), and received his M.S. (’93) and Ph.D. (’96) degrees in Electrical Engineering from the University of Illinois at Urbana-Champaign.
