Jon E. Froehlich

Associate Professor, CS
University of Washington

I am an Associate Professor in the Paul G. Allen School of Computer Science and Engineering at the University of Washington, a Sloan Fellow, and NSF CAREER awardee. My research is in Human-Computer Interaction (HCI) with a focus on high-value social domains such as accessibility, environmental sustainability, and STEM education. I have published over 50 peer-reviewed publications; eleven have been honored with awards, including Best Papers at ACM CHI and ASSETS and a 10-Year Impact Award at UbiComp. Since becoming a professor in 2012, I have taught ~250 undergraduate students and ~150 graduate students in HCI, Design, and UbiComp courses and served as a research advisor to nine graduate students, 50+ undergraduates, and 15 high school students. From 2012-2017, I was an Assistant Professor in Computer Science at the University of Maryland.

Congrats to Stefania Druga for passing her iSchool PhD dissertation defense today on the topic of Creative AI Literacies for Families. I was honored to serve on the PhD committee. Such timely, important work exploring how to develop children and family AI literacy and involve them in AI-assisted creation! Also, best title slide ever, which was generated via DALL E-2 using the new Microsoft Designer—an AI-assisted design tool (how fitting!).

Dhruv Jain Honored with SIGCHI Outstanding Dissertation Award

Feb 14, 2023 | Jon

Congrats to Makeability Lab alum Dhruv Jain (now a professor at the University of Michigan) for being honored with the SIGCHI Outstanding Dissertation Award. The Award "recognizes the most outstanding research contributions from recently graduated PhD students within the HCI community, showcasing the quality and impact of HCI research." Congratulations as well to the two other winners: Megan Hofmann and Kai Lukoff. Impressively, all three winners have UW affiliation: Kai was advised by Professors Alexis Hiniker and Sean Munson; Megan by Professor Jen Mankoff and Scott Hudson (CMU); and Dhruv by me and Professor Leah Findlater. The award recognition blurb for Dhruv reads: Dhruv “DJ” Jain is an Assistant Professor in Computer Science and Engineering at the University of Michigan, also affiliated with the School of Information and Department of Family Medicine. His research focuses on accessibility, and investigates the full cycle of identifying user needs, developing novel assistive technology systems, and studying these systems in the field. He got his Ph.D. from University of Washington and Masters from the MIT Media Lab. DJ’s dissertation advances the design and evaluation of interactive systems to improve sound awareness for people who are deaf or hard of hearing (DHH). This research, drawing on his own experience as a person who is hard of hearing, has two goals: first, to better understand how DHH people feel about technology-mediated sound awareness and how these feelings manifest across contexts; and second, to design, build, and study new technical solutions for sound using iterative, human-centered design. DJ’s dissertation makes contributions across the human-centered design pipeline, including new research methods for disability and technology design, advancing understanding of preferences for sound classification and real-time captioning, designing and implementing new interactive sound awareness systems on IoT devices, smartwatches, and augmented reality glasses, and evaluating these systems in lab studies and field deployments. The work was honored with an ACM ASSETS Best Artifact award, selected for a CACM Research Highlights article, covered by popular press venues including CNN, New Scientist, and Forbes, directly impacted real-time captioning work at Google, and yielded a released app called SoundWatch in the Google Play store that is being used by DHH people across the world for real-time sound recognition. DJ’s dissertation exemplifies the use of end-to-end human-centered research to define and advance methods and tools for real-time sound recognition, fundamentally advancing our understanding of DHH people’s needs around sound recognition and providing technical solutions to support those needs.

Dhruv Jain Honored with Willian Chan Memorial Dissertation Award

Jan 30, 2023 | Jon

Huge congratulations to recently graduated Makeability Lab PhD student—now Michigan professor—Dhruv Jain on being recognized with the William Chan Dissertation Award. The Allen School has a lovely writeup, which quotes some of my thoughts worth repeating here. “Dhruv’s dissertation research makes fundamental advances in the design of sound sensing and feedback systems for people who are deaf or hard of hearing,” Froehlich said. “Throughout his dissertation work, Dhruv has worked closely with the DHH community to understand diverse needs and evaluate his systems, including through large online surveys, interviews and field deployments.” Jain’s own experiences as a DHH individual informed his research and helped shape his focus on the user experience. “Dhruv’s dissertation not only exemplifies the human-centered design process in the creation of accessible technologies but also makes transformative technical innovations in integrating AI and HCI to improve information access,” Froehlich added. “As a testament to its impact, his work has received multiple paper awards and a Microsoft Research Dissertation Grant, and SoundWatch has been released and downloaded by over 2,000 Android watch users worldwide.” As rather surreal twist, I was honored with the same award a decade ago. It is both humbling and even more fulfilling to have one of my own students receive the award. Congrats Dhruv!

SciStarter + Project Sidewalk: MLK Jr. Day of Service

Jan 11, 2023 | Jon

We were honored and delighted to give a talk on SciStarter in honor of MLK Jr.'s Day of Service. You can view the slides here. In the words of Dr. King: Injustice anywhere is a threat to justice everywhere These words still resonate today as we continue to attempt to address systemic inequities in human mobility and transit access—for which Project Sidewalk is but one small movement forward. SciStarter is a platform for community science featuring over 1,000 research projects, including Project Sidewalk. If you join SciStarter, you can get credit for using Project Sidewalk—just make sure you're using the same email addresses on both platforms.
