Purdue University EE Building  | 
Hong Z. Tan is the Keysight Professor in the Elmore Family School of 
Electrical and Computer 
Engineering at Purdue University.
She concurrently holds courtesy appointments in the School of Mechanical Engineering and 
the Department of Psychological Sciences at Purdue University. Her research focuses on 
haptic human-machine interfaces and haptic perception. 
She has published more than 160 peer-reviewed journal and conference 
articles in haptics research. She is known internationally as a leading 
expert on haptics psychophysics, taking a perception-based approach to 
solving engineering problems. She is frequently invited to give keynote 
speeches at international conferences and research institutions, 
educating a broad 
audience on haptics and its emerging applications in human computer 
interaction, robotics, medicine and education.
 Tan received her Bachelor's degree in Biomedical Engineering from Shanghai Jiao Tong University, P.R. China. She earned her Master and Doctorate degrees, both in Electrical Engineering and Computer Science, from Massachusetts Institute of Technology (MIT). She was a Research Scientist at the MIT Media Lab before joining the faculty at Purdue's School of Electrical and Computer Engineering in 1998. She has held a McDonnell Visiting Fellowship at Oxford University, a Visiting Associate Professorship in the Department of Computer Science at Stanford University, and a Guest Researcher position in the Institute of Life Science and Technology at Shanghai Jiao Tong University. From 2011-2015, Tan was a Visiting Researcher, then a Senior Researcher and Research Manager at Microsoft Research Asia in Beijing, China. She is currently on research leave from Purdue University, holding a visiting position as the Lead Haptics Scientist at Google LLC. Tan was a recipient of the prestigious US National Science Foundation's Early Faculty Development (CAREER) Award. She was a Chinese National Natural Science Funds' Distinguished (Overseas) Young Scholar. In addition to serving on numerous program committees, she was a co-organizer (with Blake Hannaford) of the International Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems from 2003 to 2005. In 2006, Tan served as the Founding Chair of the IEEE Technical Committee on Haptics (TCH). The TCH played a key role in launching the IEEE Transactions on Haptics (ToH) in 2008. Tan has served as a ToH Associate Editor from the journal's birth to 2012, and received a Meritorious Service Award in 2012. From 2012-2015, Tan was the Editor-in-Chief of the World Haptics Conference Editorial Board, and co-chaired the World Haptics Conference with Ed Colgate in 2015. In 2017, Tan was elevated to IEEE Fellow for "contributions to wearable haptics."

			TAPS (TActile Phonemic Sleeve) for Speech Communication through the Skin 
	
			We devised a phonemic-based approach to encoding speech sounds (phonemes) as
			vibrotactile stimulation patterns on the forearm, conveyed through a 4-by-6 tactor
			array. We have tested about 100 participants on TAPS. Our results show that the
			best participants can learn up to 500 English words at a rate of 1 word per minute!
			
			
			 Our paper won the IEEE Transactions on Haptics (ToH) 
			Best Paper Award 2020,
			funded by IEEE Robotics and Automation Society to recognize the best ToH paper
			published in calendar year 2019.

			"A phonemic-based haptic display for speech communication,"
			IEEE Transactions on Haptics, Vol. 12, No. 1, pp. 2-17, 2019.
			 (This article explains the design approach of 39 vibrotactile
			patterns for the 39 English phonemes, and provides the details of the 24 position-based consonant codes
			and the 15 movement-based vowel codes.)
			
			
			 (This article presents results in terms of total learning 
			time and word recognition accuracy from 51 participants who were trained to receive 
			up to 500 English words using the TAPS.)
			
			 (This article was actually the "literature review" for the TAPS project, even though
			it took longer to be published. A practical and useful insight is that movement-based haptic stimuli is 
			vivid and distinct, and highly effective at increasing the information transmission of haptic devices.)
			
			 (This article demonstrates that task-irrelevant position-based and movement-based
			vibrotactile stimuli can be categorized without explicit attention during a visuomotor task.)
			
			 (In this article, we revise our haptic phonemic codes by taking into account the frequency of 
			occurrence of phonemes and phoneme pairs. We show that speech transmission rates could be improved by more
			than 50%.)

			Virtual Reality for Sports Training 
			We have developed three VR 
			applications for sports training -- footbal (receiver training for 
			catching a football from any direction), baseball (hand-eye coordination 
			training), and Taekwondo (training for kicking/breaking a target).
			We use haptic feedback to indicate collision with a virtual object 
			(e.g., a baseball bat).
	
	 
			Haptic Signal Design for Emotional Communication 
	
			How do we design haptic signals that feel like natural phenomena?
			We work with designers to explore ways that vibrotactile patterns can
			capture the essence of breathing, heartbeat, earthquake, bubbles, etc. 
			Our ultimate goal is to achieve visceral reactions to hand-crafted haptic
			signals.
