TilePoP，它是一種新型氣動介面部署成地磚的樣子，藉由充氣的方式可以動態形變成大型的代理物件來進行全身性的互動在虛擬世界裡。TilePoP 是由方塊形狀的空氣袋以二維陣列排列堆疊所組成。空氣袋經過特別的折疊結構設計，讓空氣袋充氣後可以變成代理物件，不需要用到的時候可以消氣回到原來地磚的樣子。TilePoP 可以提供全身性的觸覺回饋，甚至於承受人體的重量。因此，它允許新的互動可能實現在虛擬實境當中。
本文將詳細介紹 TilePoP 的設計與實現，應用程式的展示，以及初步的使用者評估結果，來了解使用者對於 TilePoP 的使用者體驗。

We present TilePoP, a new type of pneumatically-actuated interface deployed as floor tiles which dynamically pop up by inflating into large shapes constructing proxy objects for whole-body interactions in Virtual Reality. TilePoP consists of a 2D array of stacked cube-shaped airbags designed with specific folding structures, enabling each airbag to be inflated into a physical proxy and then deflated down back to its original tile shape when not in use. TilePoP is capable of providing haptic feedback for the whole body and can even support human body weight. Thus, it allows new interaction possibilities in VR. Herein, the design and implementation of TilePoP are described in detail along with demonstrations of its applications and the results of a preliminary user evaluation conducted to understand the users' experience with TilePoP.
