Talking Handle by shiyi shao from china

Talking Handle with concise icons designed to indicate various statuses inside the room expands the function of current handles.
In many cases, realizing the instant status inside the room really matters. Supposed in working environment, office workers always need to visit others to report work or communicate with others. While they often cast doubt on whether the time to visit is appropriate.
Another place to apply it is in hotel, the traditional hangtag is paper-consuming as well as inconvenient and the electric screen of presenting the states on the wall is also sort of electricity and material waste by comparing with this talking handle. As to this point, adding this function to the handle seems reasonable.
