本論文之研究主題為「意趣表現在實體產品之體現互動：以可塑性揚聲器為例」，所謂「意趣」乃為個人生活目的、需求與情感的體現方式，首先實驗利用可塑性（moldable）介面順應（adapted）人類意向性的從事活動，並比較傳統介面之間的體現差異；同時調查不同形狀介面對物品現身度（expression）的影響，看待主體特徵的利用範圍如何創造與外界的對應（coupling）關係。根據逐一「材質」與「形狀」介面的試驗，導引最終原型化結果，提升實體產品之體現。
本文實驗佐證：第一、可塑性介面（moldable interface）對體現互動有直接幫助；其介面適應能力使物件深植外在物質與社會網絡影響，有效成為環境的一部份；第二、導引主體形式特徵對物品現身度有實質提升；透過不同形狀差異比較，瞭解促成環境互動的利用元素，提供今後變形材料（deformable material）在介面設計上的考量；第三、實體產品之體現互動反映人類日常生活意趣（需求、目的與情感）；跟隨人類活動脈絡影響，以致產品（介面）形式意義現身在真實世界中，成為體現互動（embodied interaction）及遍佈運算（ubiquitous computing）之實務設計指標。
有關意趣式表現在實體產品介面上，本文建議四項設計要點：第一、可捏塑素材的適應性與表現性能力，對促成環境互動有實質助益；第二、提升環境互動包含構畫形狀介面的主要特徵；第三、主體特徵建議以分支替代單一；開放替代封閉，反差替代正規；第四、針對揚聲器產品一例，功能配對包含開口處、大面積塊狀凹凸面或隆起狀開口處為發聲介面。這些設計元素也邀請不同設計者延續不同實務應用，探索更趨向複雜之產品設計。

The study is about “Intended Expression on Tangible Products – The Moldable Speaker of Embodied Interaction”. Regarding to ”intention”, it focuses on the way of embodiment that sues for personal life, goal, and emotion. This paper looks in detail at moldable interfaces. For example, we use expressive materials as a physical presence for people’s embodiment of intended-expression. We will also investigate the design of various shapes, seeing how prominent features can be used in a form that affords users the opportunity to involve the interfaces in their everyday lives.
This research prove: that the moldable interface which involves in physical and social things becoming the part of environment is helpful to the embodied interaction; that extracting the shape of design promotes the evidence of objects availed being example of designing for deformable materials; that tangible products of embodied interaction is following the “flow” letting interface to be expressed the status of human activity. All that is practice for embodied interaction and ubiquitous computing.
We also suggest: that the moldable interface is valuable by its adjustment and expression for improving interaction within a surrounding context; that good moldable interface is draw of prominent features; that the form of design is composed of multiple elements rather than single one, opened rather than closed, and diversity rather than union; and that the coupling of function has three modes to activate device regarding the moldable speaker. The element of design invited other designers to explore diversely the potential application towards more complex products.
Taking these ideas into consideration, this paper will concentrate on Organic User Interfaces (OUIs) as manifestations of physical objects. Being suited to the concept of OUIs, the Moldable Speaker has become a new vision for a tangible product, except for flexible displays.
