Bonus Episode: Markerless Motion Capture | Scott Selbie

In this episode, we dive into markerless motion capture with Dr. Scott Selbie, the Chief Executive Officers of Theia Markerless Inc, Director of Research at C-Motion Inc, an adjunct Professor in Mechanical Engineering at Queen’s University and in the department of Kinesiology at the University of Massachusetts.

We talk about the exciting future of markerless motion capture, the barriers of markerless becoming the new “gold standard” to motion capture, and how Theia aims to overcome these challenges. We also discuss start-ups, industry, and (one of our favorite topics) failure!

Additional clarification: To add to our discussion about discussing feature identification, we wanted to add the note that the salient points for the neural network are points that are not necessarily equivalent to the locations that markers are placed. With a physical marker, palpation identifies bony landmarks. For salient features it is less important that the marker represent a bony prominence than it is a location that can be reliably identified on a video image. It turns out that the reliable locations are not coincident with a bony prominence.

Theia Markerless is a young start-up that is revolutionizing motion capture in biomechanics by harnessing machine vision and artificial intelligence to provide incredibly accurate markerless motion capture software that is simple, powerful, and versatile.

Today we are talking with Professor Jacob Goodin. Jacob is an Associate Professor of Kinesiology at Point Loma Nazarene University in San Diego, California, and was previously the head strength and conditioning coach and sport scientist for Eastern Tennessee State University’s men’s and women’s tennis teams. We learn more about Jacob’s work in the lab and as a biomechanics teacher for many students around the world through his fantastic YouTube channel. His videos spanning movement science – from at-home workouts to statistics in kinesiology, all taught in a free, accessible, and exciting way – so much to learn from!

We had a great conversation with Professor Nadia Azar, an Associate Professor of Kinesiology at the University of Windsor. For the first time on BOOM, we learn about the biomechanics of drumming and playing other musical instruments. Nadia shares her findings on the mechanics of how playing-related injuries occur and how to prevent them, along with her own journey through biomechanics and music, and how learnings from each can inform the other. One of our favorite takeaways was from Nadia is where she talks about her quest to be an imperfectionist, and learns that at some point you just have to say, “F*** it, the essence is there.”

We talked with Professor Hamid Charkhkar from Case Western Reserve University and the Cleveland VA Medical Center and Anna Smith, a former Case Western student and research assistant in Professor Charkhkar’s neuroprosthesis group. We discussed the importance of being open to feedback from all stakeholders for human-centered research, how to translate that into holistic treatment strategies personalized to individual users, and about the impactful neuroprostheses that integrate sensory abilities being developed by Hamid’s lab. Anna highlights her experience learning that “I don’t know” is a valid answer in research while Hamid reminds us that things not going according to plan is an expectation in human research.

This Student Voices episode is hosted by Michael Rose, a former clinical research coordinator and soon-to-be PhD student. In the episode Michael interviews three friends and colleagues – Ophelie Herve from UCLA, Gabi Diaz from CU Boulder, and Garrett Weidig from Michigan State University – on their experiences starting their PhD programs in 2020 during the COVID-19 pandemic. Topics range from integrating into new environments under lockdown measures and the pandemic’s impact on early research progress to how expectations were managed and advice for future graduate students.
