Fitness trackers and smartwatches are widely used to monitor health, activity and exercise, but they’re pretty sedentary themselves. They stay strapped on your wrist or clipped to your clothing despite the fact it’s more effective to monitor different areas—your upper body for breathing, for example, or your wrist to track typing or writing.

Now, researchers at the University of Maryland are putting wearable sensors on track to do their best work—literally—with a miniature robotics system capable of traversing numerous locations on the human body.

Their device, called Calico, mimics a toy train by traveling on a cloth track that can run up and down users’ limbs and around their torso, operating independently of external guidance through the use of magnets, sensors and connectors. Their paper describing the project was recently published in the ACM Journal on Interactive, Mobile, Wearable and Ubiquitous Technologies and presented at UBICOMP, a conference on ubiquitous computing.

“Our device is a fast, reliable and precise personal assistant that lays the groundwork for future systems,” said Anup Sathya M.S. ’21, who led Calico’s development for his master’s thesis in human-computer interaction. Sathya is now a first-year Ph.D. student in computer science at the University of Chicago.

Most wearable workout devices are limited in the type of exercises they can monitor, but Calico is versatile. For example, it can track running on a user's arm, move to the elbow to count push-ups, to the back for planks, and then to the knee to count squats.

And unlike other devices, Calico moves quickly and accurately without getting stuck on clothing or at awkward angles. “For the first time, a wearable can traverse the user’s clothing with no restrictions to their movement,” said Huaishu Peng, an assistant professor of computer science who was Sathya’s adviser at UMD.

Peng, who also has an appointment in the University of Maryland Institute for Advanced Computer Studies (UMIACS), sees a future in which mini wearable devices like Calico will seamlessly integrate with humans for interaction, actuation and sensing.

He recently took Calico in a creative direction by establishing a new collaboration with Jonathan David Martin, a lecturer in Immersive Media Design; and Adriane Fang, an associate professor at the School of Theatre, Dance, and Performance Studies.

The interdisciplinary team is combining dance, music, immersive media, robotics and wearable technology into a novel and compelling series of interactive dance performances that are choreographed in real time through Calico.

First, Peng’s research group programmed Calico to instruct a dancer to execute specific movements using motion and light. Then, using their smartphones, the audience gets to collectively vote on how Calico should instruct the dancer.

The project is being funded with a $15,000 award from the Arts for All initiative, which leverages the combined power of the arts, technology and social justice to make the University of Maryland a leader in addressing grand challenges.

“The idea is to explore the dynamics and connections between human plus robot and performer plus audience,” said Peng. “In this instance, Calico will and act as the ‘mediator’ to broadening art and tech participation and understanding.”

Calico’s original creators include Jiasheng Li, a second-year Ph.D. student in computer science; Ge Gao, an assistant professor in the College of Information Studies with an appointment in UMIACS; and Tauhidur Rahman, an assistant professor in data science at the University of California, San Diego.

$9M Gift Founds New Institute for Performance and Technology in the Arts

A family with multigenerational ties to the University of Maryland is giving $9 million to its School of Theatre, Dance, and Performance Studies (TDPS) to boldly reimagine the future of education in the performing arts. 

Mathematics Professor Emeritus Michael and Eugenia Brin and the Brin Family Foundation are establishing the Maya Brin Institute for New Performance, which will add courses, expand research and fund new teaching positions, undergraduate scholarships, classroom and studio renovations, and instructional technology.  

The gift brings the university’s fundraising total for its Fearless Ideas campaign to $1.4 billion, approaching its record $1.5 billion goal by the end of this year.  

“We are incredibly proud of our university's connection to Michael, Eugenia, and the entire Brin family, and we are grateful for their continued generosity as champions of Maryland,” said Darryll J. Pines, president of the University of Maryland. “There has never been a more timely moment to apply technology to the arts to extend their reach and inspiration.”

Leaders in TDPS and the College of Arts and Humanities, where the school is housed, say the institute will advance TDPS’s role as an innovator in design and performance, and prepare graduates to launch careers in emerging media formats such as webcasts, immersive design technology and virtual reality performance.

The institute will allow TDPS “to make transformative advances in the work that they have begun doing to bring technology into the performance domain,” said the college’s dean, Bonnie Thornton Dill. “We will be at the forefront of applications and modifications of technology and theater. We’ll be able to expand our existing work and really become a national leader.”

The Brins, parents to Google co-founder Sergey ’93 and Samuel ’09, have previously made several significant gifts to support the university’s computer science and math departments and Russian and dance programs, the latter two to honor Michael’s late mother, Maya. She emigrated with her family from the Soviet Union in 1979 and taught in UMD’s Russian program for nearly a decade. She also loved the performing arts, a love she tried to instill in her children and grandchildren by taking them to the ballet and theater, said Michael Brin.

The idea of combining the arts and technology inspired this new gift. “I want to … open opportunities to the students and faculty in interactions between new media and traditional art,” said Brin, who retired from UMD in 2011 after 31 years on its faculty.

As the COVID-19 pandemic continues, halting most live performances for nearly a year, theaters and concert venues have sought to find creative ways to present plays, dances and musical performances over a screen. Jared Mezzocchi, associate professor of dance and theatre design and production, co-directed TDPS’ groundbreaking Zoom production in May of the fantasy “She Kills Monsters;” recently, his digital work “Russian Troll Farm,'' featuring memes, animation and virtual backgrounds, was honored as a New York Times Critic’s Pick.

The Maya Brin Institute is “giving us the opportunity not only to experiment with new technology, but to innovate new processes to create performance,” said Mezzocchi. “This is a glorious opportunity for our school to reach its goals as part of a Research I institution: taking what we have explored technologically throughout the pandemic, and launching us into a future of accessible, immersive, interactive and multidisciplinary performance.”

A new light and technology studio and multimedia labs and an upgraded dance studio in the university’s Clarice Smith Performing Arts Center will provide creative space for five additional faculty positions in lighting design for camera, live digital performance, technology and multimedia production, and other fields. Full-stage green screens, GoPro cameras, laser projectors and remote rehearsal technology will broaden performing options. Future classes will include “Video Design for Dance and Theater” and “Experimental Interfaces and Physical Computations.”

TDPS, home to approximately 250 students, has long served as a pipeline of talent for the thriving Washington, D.C., theater and dance community, including the Kennedy Center, Arena Stage and Dance Place; 19 Terps were nominated for the regional Helen Hayes Awards last year.

The school combines experience on the professional-quality stages and rehearsal spaces in The Clarice with teaching from nationally recognized faculty (such as five-time Tony winner for Best Lighting, Brian MacDevitt) in the context of a liberal arts education incorporating arts, society, science and technology.

The Maya Brin Institute will bolster students’ credentials even further. “Our students will have knowledge and experience that will prepare them to be among the first people hired as this new technology develops,” said Thornton Dill.

To Maura Keefe, TDPS director and associate professor of dance performance and scholarship, the institute will allow the school to propel students to the forefront of the field by focusing on what performance is about: creativity and exploration.

"We’re going to see (the influence of this gift) in every performance," she said. "The excitement from the students who are exploring the ideas—that’s going to show up across the work we’re making."
