In the interactive installation Smiling Buddha , we aimed to “pass on” a smile from one observer to the next. Thus, we have designed a natural interactive process that keeps passing on smiles. The system captures the moment at which an observer smiles before kinetically recording the moment and saving the images. The system does not merely record an image from a single angle; instead, the device records the user’s smile from various angles during the interaction. The final smile features different angles of smiles from previous users together with the smile of the present user. After completing the interactive experience, the user’s data will be saved and transmitted to the “Smiling Database,” where the smiles of past users will then be reproduced in the display area. Through the vast quantity of smiles, we wish to achieve our core concept of “passing on a smile.”
