In this talk, Dongwook Yoon will present rich collaboration systems that are designed to bring the expressivity of human-to-human interaction into online collaboration. Face-to-face interaction, as compared to meeting in a virtual way, offers unmatched expressivity for conveying complex ideas and nuanced emotions (e.g., emotions embedded in voice inflection or the unspoken meaning of a pointed finger).
To enhance expressivity of virtual collaboration tools, Yoon's design approach translates such natural human interactions into novel combinations of input modalities (e.g., speech, writing, and gesture) that serve as building blocks for fluid, rich, and lightweight interfaces. Yoon built, deployed, and evaluated high-fidelity systems in real world contexts (e.g., classrooms), from which we can obtain ecologically valid user data. He plan to pursue the vision for rich collaboration systems by extending his approach to mixed reality, a promising next generation computing platform.
