If we take a chair along when going for a walk, we can sit and have a rest on it when tired. They are many kind of portable chairs on the market, but more of them only have general functions. In summer, it is hot and rains a lot. However, we need umbrellas when going out thus causing some trouble in carrying them along. This situation creates a demand for a smart portable chair that can also shield sunlight or rain. In view of this, we presented the device.
