人與人之間的情感隨著現代科技的進步，聯繫變得越發容易，可以跨時空同步交流。雖然科技帶給我們便利與進步，情感卻逐漸退步。忘了最重要的互動，只是一昧地在小框框裡複製貼上的噓寒問暖。

童年時期盪鞦韆，互相比賽誰盪的最高，又互相幫對方推得高而遠，有競爭也有合作，純真的互動，不用言語，就可以達到最純粹的溝通。

擺盪的距離隱喻人與人之間，不在只有距離遠近還有情感深淺。

「純粹互動」——純粹「只是」一個「互動作品」／純粹人與人之間最「純真」的「互動交流」。

Because of the progress of technology, contact between people has become easier. Our communication has come to transcend the barriers of time and space. Although technology is bringing us new convenience and progress, the emotional aspect of our lives has gradually regressed. We’ve forgotten the most important interaction, merely copying and pasting messages senselessly.

In our childhood, as we played on the swings, we not only competed to see who could swing higher, but also helped each other push to swing higher and farther. There were, parallely, competition and cooperation. Pure interaction, without words, can achieve pure communication.

The distance between the swing metaphor people, not only the distance but also emotional depth.

"Pure Communication " - is purely, "only" a "interactive work" / most purely human, "pure" in " communication ".
