互動設計 | ReUnit

動手創造出屬於自己的雪山，讓我們一起來滑雪吧～

Make your own mountain, and let's go skiing together!

【 ReUnit 】

Re 重新、Unit 最小單元——重新解構最小單元

Re, Unit——Reshape the smallest unit

【緣起構想 Origin 】

在過去的互動體驗上，大多都是在單純虛擬中看到效果，或實體操作後都是在另外的螢幕上看到體驗效果，

而我們想創造的互動體驗是讓使用者能真實的碰到實體的紙張，且在創造體驗的過程中，

能在手上的操作媒材上以肉眼直接看到即時的反應，而不是在另外的設備、螢幕上看到效果。

The interaction design in the past, most of the effect we see is virtual or on the other screen after manipulating.

We want to create a new interactive experience for users to touch the material, which we made, actually and see the result immediately by eyes from the material, instead of from other equipment or screen.

【設計概念 Concept 】

《ReUnit》為一個跨領域設計的互動體驗裝置，體驗者對「布紙布」動手創造出屬於自己的山，

並結合實體投影在體驗者創作的山上面，產生即時互動體驗，創造出育樂、舒壓的效果。

"ReUnit" is an interdisciplinary interactive installation. Users make their own mountain by the "paper" which we made, and we project the image directly on the mountain to create a stress-relieving as well as having an educational meaning interactive experience.

將使用者在現實空間創造的實體山，於虛擬空間中重新建構，運用反光原理將使用者在實體山上滾動的路徑記錄存取，

同時將角色投影在實體的桌面上，在實體與虛擬中呈現交錯，讓作品不止呈現在實體或虛擬中。

Users will make the mountain in reality, and the mountain will be deconstructed in the virtual space. Using the principle of reflection to capture the path which users make, and project the characters on the mountain at the same time. So the images can be presented in reality as well as in the virtual space.

【互動流程 Steps 】

造山 make mountain - 拿起雪球 pick up the snow ball- 滑雪 ski - 送上主世界 represented in the main world

【互動技術方法及運用 Technical application 】

《ReUnit》是一個結合了投影影像、裝置系統、互動程式、實體操作，多個跨領域的專業結合以呈現出一套完整的作品。

為此我們使用了Unity、Processing、Kinect、Arduino 這幾個不同的軟體硬體來作組合。

運用Kinect的紅外線感測抓取深度值，在Processing進行影像分析、及Arduino的簡易感測，紀錄使用者操作中的各個狀態。

再運用Unity來做視覺上的呈現，以及配合對位投影來達到我們所要呈現的效果。

"ReUnit" is an installation which combines projection, programming, visual design and interaction. In order to make this project, we utilize the software and hardware such as Unity, Processing, Kinect and Arduino.

Using the infrared of Kinect to catch the number of depth; Processing is used for analyzing the image; Arduino is responsible for giving feedback, and using Unity to display the images and match the images with the mountain.

【即時互動體驗】

運用影像辨識、對位投影的技術，讓體驗者可以即時在山上直接看到投影的效果。

Users can directly see the effects on the mountain by applying the technique of image recognition and projection mapping.

【虛實空間轉換】

運用紅外線的特性，將使用者所做創造的山，運用程式運算的方式，在虛擬空間中重新模擬呈現。

The mountain which users make can be represented in the virtual space by utilizing the infrared and programming.

【布紙布 About the new material 】

世界萬物最簡單的原型 - 點線面，由最簡單的點連成線，線組成最小單位的三角面

解構三角面開發出的特殊媒材「布紙布」

Everything in the world can be deconstructed into dot, line and phase, and we use this concept to create a new material called "布紙布".

我們希望讓體驗者在互動過程中有最理想的操作體驗，經過我們對三角面多次排列組合與不同材質搭配後，我們在紙中加入了布與磁鐵，運用「布」不易破的特性及能降低反光增加體驗時的偵測效率，利用「磁鐵」容易吸附於鐵片的特性，最後做出了能讓體驗者任意創造、揮灑創意的「布紙布」。

We hope users can reach the best experience from the interaction, so we have tried many different arrangements of triangle and materials. In the end, we decided to use one kind of cloth to strengthen the flexibility of the material and put the many little magnets into it to let mountain can be made easier.
