S Introducing SCS Moonshots

W G OR IN LD CHANG

The first search engine. The first wired — and a decade later, wireless — campus. The nation’s first robotics institute and the advent of artificial intelligence. All of these initiatives started in the School of Computer Science. Each has transformed our lives. Today, a new SCS Moonshots initiative continues this rich history of boundary-breaking innovation. While research projects abound in all seven SCS academic units, those selected as Moonshots have been presented to an interdisciplinary team of faculty and staff who have deemed them the most likely to significantly impact the world in the years to come. SCS Moonshots receive the financial support and resources necessary for taking risks and achieving success from the Dean’s Innovation Fund, and are vetted by the SCS College Council and Alumni Advisory Board. In keeping with CMU’s legacy of world-changing innovation, the Moonshots projects will prove that when the best and brightest minds focus on a common goal, amazing things happen. This story, first in a series to be featured in The Link, introduces you to one of those Moonshots: FarmView.

Thanks to new functionality developed by Human-Computer Interaction Institute researchers, your smartwatch could soon recognize objects and activities by monitoring the vibrations that occur when you hold something or use a tool. It could even be used to help tune a guitar. All that’s required is a software upgrade that repurposes the device’s existing accelerometer, allowing it to act like a vibrational microphone. This new technology, dubbed ViBand, was developed by Ph.D. students Gierad Laput and Robert Xiao — both members of the HCII’s Future Interfaces Group — and their adviser, Assistant Professor Chris Harrison. Rather than detecting sounds transmitted through the air, ViBand works with the body to detect bio-acoustic signals. A ViBand-enabled watch can tell if someone is tapping on the forearm, palm or back of the hand. It can detect finger flicks, scratches and other motions. It can also sense if a person is holding various mechanical and electrical tools, such as an electric toothbrush, power drill or handsaw. “It’s as if you’re using your hand as a detection device,” said Laput, suggesting totally new uses for smartwatches. “The hand is what people use to interact with the world.” The team presented a paper describing their work in October at the Association for Computing Machinery’s User Interface Software and Technology (ACM UIST) Symposium, where they took Best Paper honors.

Blum was instrumental in establishing Women @ SCS, a faculty/student organization that helps women make connections across the school, and in recognizing that it’s the computer science culture — not the curriculum — that needs to change to accommodate women. This year’s class of 166 first-year undergraduates is about 30 percent larger than previous classes. SCS decided to expand undergraduate enrollment in response to the growing need for computer scientists in industry.

26 THE LINK WINTER 2016 27 HAVING A BALL IN THE OFFICE OF ENGAGEMENT AND ANNUAL GIVING

It’s been about a year since Niccole Atwell and I joined the School of Computer Science as the newly formed Office of Engagement and Annual Giving, and to borrow from “Hamilton” (for any of you Broadway fans out there), it’s been nonstop since then. We’ve learned a lot this year, but one of our first lessons was that computer science alums are FUN! In what other universe would the director of our Alumni Advisory Board have us jump in Google’s ball pit for a photo op? We’ve met so many of you, on campus and around the country. We’ve traveled to meet you in Silicon Valley. In Boston, New York City, Seattle. Silicon Valley again. We’ve learned that you really like swag, but — all kidding aside — that you also want to learn about what’s going on at CMU. You want to know what kind of research is happening on campus, and you want to meet the faculty members you remember and ones who might be new to you. You want to talk to our students and hear about their CMU experiences. You want to feel connected. You’ve also shown us so much this year. Your spirit of volunteerism and community involvement shined through in your response to our request for participants in both the student mentoring program we began, and in the TEALS tutoring program we’re piloting in the Pittsburgh Public Schools. (See the story on page 10.) Some of you have worked with your employers to help sponsor events, and even more of you have chosen to financially supportSCS and our students directly. We’ve recognized these donors in the special section beginning on page 30, and have included a card in this issue to make giving as convenient as possible. You can also make a gift at http://bit.ly/scsgiving2016. Above all, you’ve welcomed us into the CMU SCS alumni universe this year and taken us in as part of the family, and that’s been incredibly rewarding. We hope we’ve provided you with more of the types of interactions with your alma mater that you’d like to have. And while we know that some of you have stronger ties to CMU than others, we’re working to strengthen those ties across the board. We have big plans for 2017. We’re working on a more robust website that will easily connect you with opportunities to engage with SCS. We’re planning events that respond to your feedback and needs. We’re working harder to connect you with students, and to help ensure that from the time they enter the Gates Hillman Centers, they feel the same warm welcome into the SCS family that we’ve experienced this past year. It sounds like a huge challenge. Sure. But that’s our job, and we love to do it.
