在智慧型手機與平板電腦日益普及的今日，影片觀賞的平台從傳統的電影院大銀幕、家中的電視機與電腦，擴展到使用者手中的隨身影音播放裝置。然而，有關行動觀影平台使用的研究，不論在質與量方面，仍顯不足。因此本篇論文，採用質性閱聽人研究方法，檢視一般閱聽使用者在日常生活中的「行動觀影」實踐，分析「行動觀影平台」的出現會如何影響「居家觀影活動」的內容、脈絡與閱聽使用者的日常生活。

With the innovation and proliferation of wireless Internet connectivity and mobile audiovisual technology, audiences nowadays can enjoy the flexibility of watching moving images, such as movies, TV programs, and short videos everywhere, ranging from multiplex theatre, comfortable home to corners of coffee shop and carriage of train. By using various kinds of available portable media devices like smart phones, I-PODs, PSPs, and laptop computers, virtually, everywhere can become the place for enjoying audiovisual contents. The concept of ‘cinema or movie theatre' as we normally understand has been changed from stationary places to mobile locations. The ways how audiences employ different mobile technologies to watch different moving images from different venues have profoundly changed the meanings of their everyday viewing practices. However, not enough of researches have been done to examine this often-understudied phenomenon. In this paper, a qualitative audience research method inspired by ethnographical survey is employed to examine mobile viewing-practices of Taiwanese audiences/users, with attempts to further analyze the effects of using mobile-viewing platforms on video-viewing activities and contexts of audience/users' everyday lives.
