Improving user involvement through live collaborative creation
Creating an artifact, such as writing a book, developing software, or performing a piece of music, is often limited to those with domain-specific experience or training. As a consequence, effectively involving non-expert end users in such creative processes is challenging. My research focuses on creating interactive systems that support live creation and collaboration, in which the process of creating an artifact is visible in real time to end users and invites them to collaborate with others. These systems help preserve our natural expressivity, support real-time communication, and facilitate participation in the creative process. Through these interactive systems, non-expert participants can collaborate to create such artifacts as GUI prototypes, software, and musical performances. For example, one of the systems that I developed enables large-scale audience participation at a public concert, where audience members collaboratively perform a piece of music using their smartphones. My thesis work has explored three topics linked to live creation and collaboration: (1) the challenges inherent to collaborative creation in live settings, and computational tools that address them; (2) methods for reducing the barrier of entry to live collaboration; and (3) approaches to preserve liveness in the creative process, affording creators more expressivity in making artifacts. Enabling collaborative, expressive, and live interactions in computational systems will invite the broader population to take part in creative practices.

Bio: Sang Won Lee is a Ph.D. candidate in Computer Science and Engineering at the University of Michigan. His work lies at the intersection of human-computer interaction and computer music. His research aims to bring the collaborative, live nature of music making to computational systems by developing interactive systems that facilitate real-time collaboration on creative tasks. His work explores how to computationally mediate musical collaboration and enable novel musical expression. More broadly, he has applied his findings from interactive music to applications in a variety of fields, including crowdsourcing, design, writing, and programming. These systems help people collaboratively create artifacts and experience liveness while collaborating with other people. He holds a diploma in Industrial Engineering from Seoul National University and an M.S. in Music Technology from Georgia Tech. He has been an active author in top-tier computer music conferences, such as New Interfaces for Musical Expression (NIME), as well as broader human-computer interaction venues, like ACM UIST and ACM CHI. In addition to academic research publications, he has presented his research in the form of musical performances at peer-reviewed venues, including NIME, Art-CHI, and ICMC He is a winner of the International Computer Music Association–Music Award 2016 for his composition Live Writing: Gloomy Streets.
