Recently, media technologies develop, processor miniaturize, personal fabrication spread, the idea of physical computing and internet of things realized by degree. There is report that have vision for future architecture where the physical features of architectural elements and facades can be dynamically changed and reprogrammed according to the environment and to people’s needs. On the other hands, in the city, various type of information are available in abundance all around us. but interactive media is limited. In this paper, we focus on the light, especially in sunlight and shadow. This research will integrate interactive media technologies into the design of architectural modular screen structures. we tried to make prototyping. we propose a simple modular framework for architectures. Our module can be connected by magnetic parts by a easy way to attach and detach. Once we connected modules in a matrix shape, all modules are enable to be controlled by a software.
