科技的演進可能改變了人們的生活行為。隨著智慧型手機的快速成長，數位敘事將會以一種嶄新的方式產出行動內容。我們透過互動設計的元素以及「行動敘事」的特性為依據，設計了一個無所不在的「行動協作數位敘事平台」，以促進這個改變能實現。利用這個平台，使用者根據他/她的所在地，不僅可以下載閱聽附近的行動內容，並且可以增修或記錄周遭的事物後上傳。我們並加進「協作」的功能到此平台，以提昇內容的多元與豐富，使得閱聽者，更能夠沉浸在敘述的內容當中。除此之外，本平台也增進網路技術，使其可以在離線時仍然可以持續記錄與協作內容，不受時空限制。 我們建置了這個平台以APP的型式在Android系統上呈現，並作田野實驗，以研究此新的行動協作敘事型態。我們針對平台進行兩個部分的評估與分析，其一為使用者介面的評估，我們以放聲思考法進行，並隨後對介面做出修正；其二為平台系統使用評估，此部分以訪談法進行，並同時與系統Log作比對驗證。平台實驗發現的設計元素以及使用行為，希望可以在未來對此領域欲進一步研究者，提供很好的建議。 / Technologies could change users’ behaviors. As the recent growth of mobile smartphones, digital narrative would have a new way to create mobile content. Through interactive design components and features of “mobile narrative”, we design a "Mobile Collaboration Digital Narrative Platform" to facilitate this change. A user can retrieve nearby mobile content, and also have the ability to add, edit or record what is happening at his/her present location. By adding the feature of “collaborative content creation” to the platform, the content can be made more diverse and rich and the reader can better immerse him or herself in it. Moreover, by the enhanced network technology, the platform can also work in offline mode to make it function ubiquitously. In order to study the new type of mobile collaborative narration, we develop the system (an Android App) and do field trial. We evaluate and analyze the system for two parts: one for the assessment of the user interface, and the other for system usage evaluation. We use the think aloud method for the former to amend interface design. For the latter, we interview with users, which are also compared with the system log for justification. The design components and the results for usage behaviors that we found from the new platform will provide a good recommendation for future further study in the field.
