Research Interest: Human-Computer Interaction (HCI), Mixed Reality, Human Perception (e.g. Illusion, Dream), Game

Po-Yao (Cosmos) Wang is a Ph.D. candidate at the Exertion Games Lab, Monash University, Australia. His current research interests revolve around interactive technologies that facilitate playful sleeping experiences, with a particular focus on lucid dreaming. Prior to chasing his “dream”, Cosmos conducted research on illusions, games, augmented reality, and virtual reality. He earned his Master’s degree from the Computational Physicality Lab, National Taiwan University, Taiwan and worked with Liwei Chan at National Yang Ming Chiao Tung University, Taiwan.

In addition to his academic pursuits, Cosmos is an indie game developer/designer at the HCI Game Lab. He is currently cooking up a storm with a Chinese Chess rouge-lite game called Chexel: the caterers’ checkmate. In his spare time, he is an otaku who not only watches anime but also plays tons of video games. He wishes one day he could put on the NervGear and dive into Sword Art Online.

“Your limitation (in lucid dreams) is only your imagination.”
