Braindance is an interactive play experience through a forest while the environment changes in response to the player’s change of state of mind. This project explores a new way to design experiences that utilizes the unique characteristics of Brain Computer Interface(BCI) and avoids some current limits of this technology such as high latency and low feedback. The purpose of this project is to propose the possibility of using brainwave data as an involuntary input, and discuss this approach as the possible solution to some of these major deficits of integrating Brain Computer Interface(BCI) into games and other interactive experiences.
