Digital interactive experience has been seen as the most influential trend in the recent decade. Further integration of programming, mechanisms, and design approaches has led to the redefinition of devices, products, and even large-scale architectural elements. This project aims to propose a possible integration of programming, mechanism, and ceiling design that could be applied to larger scale interface including the ceiling of the interior space or the architectural facade. By identifying human’s specific movements of hands, the shape of the ceiling would transform. This interactive relationship represents the identifying interface of today’s era. An era of digital interaction and perception.
