Abstract:	全球手機數量成長迅速[20]，功能更是日新月異。越來越多的手機整合了通訊與PDA功能，除了提供個人資訊管理外，還能執行如電子字典、影音播放、遠端遙控與衛星導航等實用軟體。然而，隨著硬體的快速發展，使用者對於手機應用程式的要求也日益多樣化。但在現實考量下，手機軟體開發業者經常以市場規模為研發的主要依據，鮮少考慮特殊的個人化需求。為此，許多手機用戶經常需苦等軟體業者的開發腳步，甚至為了某些特殊功能而更換手機，嚴重影響手機應用領域的拓展。為解決上述問題，本研究以符合MIDP規格之手機為目標裝置，發展了一套手機專用的虛擬應用程式建構系統- Virtual Application Building System for MIDP (VABS for MIDP)。本系統結合Programming By Demonstration與Direct Manipulation的精神[9]，讓不具程式能力的手機用戶能透過簡易圖形介面自行設計所需之手機軟體。藉由VABS所提供的建構器，使用者可自行剪裁、組裝PC上現有應用程式功能，以產生手機端的『虛擬應用程式』。產生的程式經安裝至手機後，便可透過與PC端的無線網路連結來運作。由於整個過程不涉及任何程式設計，適用範圍將可涵蓋僅粗通電腦的手機用戶。為驗證系統之實用性，我們以三個典型範例說明其應用場合，並實際在智慧型手機上執行。此外，我們也與傳統的遠端桌面控制軟體進行傳輸量與操作時間比較，數據顯示本系統均可獲得較佳結果。 In the last few years, the rapid growth of global mobile phone markets is obvious to all. In the meanwhile, the functions of mobile phones are also enhancing by incorporating a lot of useful features other than speaking, such as personal digital management, dictionaries, multimedia support, or even GPS applications. Following with the remarkable development of hardware, the diverse demands for the mobile phone software are also emerging. However, at present, the development of commercial software for mobile phones is seldom based on fulfilling the specialized needs of users but on the principle of cost-effective. Thus, end users may buy a new phone just because it equips with some software that the old one doesn’t have. Such a pathetic situation seriously restrict the application of mobile phones. To alleviate the above problem, a Virtual Application Building System for MIDP-compliant mobile devices (VABS for MIDP) is proposed in this paper. The goal of our work is to provide the end users a tool to construct their own mobile-phone software. In particular, the construction of a personalized software is not involved with a forbidding programming process. For this purpose, the system is built on the concept of programming by demonstration and direct manipulation. By means of VABS, the user can tailor and combine the existent PC software to generate a virtual application for mobile devices. After installing on a mobile phone, the virtual application can operate through the wireless connection between PC and the mobile phone. To verify the practicability of our system, three typical examples are presented and the communication cost of virtual applications are also compared with that of traditional terminal service client. The obtained results demonstrates the effectiveness of the proposed system.
