With the previous study on IOT, which is a future trend, I intended to apply the new technology in office space. The idea of applying the principle of finger joint allows more flexibility in smart office. This we-work office has all the functions on individual platforms on the first floor. People who work here can control the joint between the platforms. With this method, we can save space by transforming the function from individual platform to multiple platforms, and we can bring two irrelative functions together by controlling the platforms. This design represents my imagination for office in future - users can have more commands in the space they use through technology.
