"Activating the Physical" – The border between the physical and the digital world is gradually dissolving. In the 2000’s Yasuaki developed various Augmented Reality works using projection technologies. By illumination through digital pixels, physical objects can virtually change it's appearances. These effects appear to be real, but are still virtual. To accelerate the fusion between bits and atoms into the real, he's developed technologies to hack and activate the physical properties of objects and materials. In the research group he leads at Keio University, they are designing devices that can extract changes and behaviors from familiar materials by controlling conditions of different energy fields. Shape, movement, and color are examples of material behaviors that can be controlled through structured light, invisible light, ultrasound, air flow, or magnetic power. His current research aims to augment human activities based on these technologies.
