摘要

隨著科技的進步，人們能以更自然的方式與系統互動，像是能夠揮動控制器來打棒球，或是直接用手拖曳旋轉螢幕上的物件。這些新的互動方式打破了過去只能用手指操作滑鼠鍵盤的使用經驗，讓使用者身體的其他部份也能夠參與互動，操作的行為也因此更貼近日常生活的習慣與動作。
在人機互動的領域，有許多相關雙手互動的研究，企圖藉由雙手的合作，讓使用更為方便、直覺、有效率。智慧型的手持裝置通常都具有許多感應器可供雙手操作，像是多點觸控螢幕、加速器感應…。人們也常常利用雙手來使用這些裝置，但目前的介面設計仍然十分缺乏雙手互動的考量。仍然以單手操作為主要的互動方式。在相關的研究中，關於手持裝置的雙手操作研究也十分少見。本研究的主要目的是針對這個議題，探討如何讓使用者能夠利用雙手與手持裝置互動。
本研究首先透過實際觀察同樣是雙手在空中進行任務的捏麵人。瞭解活動中雙手的分工，雙手各扮演的角色，雙手的手勢和治具(棍子)的使用方式。治具在操作和檢視人偶上，提供了捏麵人師父很大的幫助。藉由這些發現，在手持裝置上，本研究提出了五項設計準則與三個設計模式，並製作三個設計原型以進行後續的使用者評估。
基於使用者的評估，最後本研究提出了四項設計模式：(1) 透過治具操作立體物件。(2)雙手移位物件。(3)雙手放置物件。(4)傾斜裝置以翻頁。
本研究所提出的設計模式包涵了雙手互動介面中合適的雙手合作模式、介面隱喻與注意事項。並詳細描述了其可解決的問題、相對應的解決方法與範例。提供了手持裝置介面設計師具體且有彈性的設計建議。

With the development of technology, the interaction with interface has become natural just like the interaction with real objects in daily life. The involvement of body in the interaction is also increased. In contrast with past interface that only consist of mouse, keyboard, or joystick, these natural interface give better experience to users.
In Human-Computer Interaction, many researchers and designers have presented manifold bimanual interactions in different platforms. But in mobile device interface, there is a lack of bimanual interaction in general functions although people usually use the mobile device with two hands, and the related research is also seldom. The aim of this thesis is to explore which kinds of interaction design are suited to the bimanual interaction in mobile device.
Through an exploratory study of a traditional Chinese handicraft – pinching dough dolls, the various perspectives of bimanual interactions, including cooperation, roles of each hand, and the usage of the jig, were investigated. Based on the findings, design guidelines for building natural bimanual interactions in mobile devices are developed, and related design patterns are presented to demonstrate the practical applications of guidelines. To evaluate the usability and acceptance, three different prototypes were built and tested in real context.
Finally, this thesis developed three design guidelines: (1) Pattern 1 3D Manipulation with Jig. (2) Pattern 2 Bimanual Relocation of Object. (3) Pattern 3 Bimanual Object-Placing. (4) Pattern 4 Tilting to flip the page with touching to use tools.
The design patterns include the appropriate bimanual cooperation, usage of metaphors, and the concerns for building bimanual interaction in mobile devices. They describe the application of design guidelines, including what kinds of problem that designers face, how to solve, and the examples of solutions. This study provides designer concrete and elastic suggestions and improves current mobile device interaction design.
