这是一件以反映孩子们在与外界交流的过程中存在的问题为目的的交互装置。主体是一件防护背心，在前胸处悬挂了一块印有靶子图案的磁力布，后背则用粘土塑造了一个特殊，脊柱外露的身体结构.

It is an interactive device designed to reflect the problems of children in the process of communicating with the outside world. The main body is a protective vest with a magnetic cloth printed with a target hanging from the chest and a special, spin-exposed body structure molded from clay on the back.
