智慧手機和電腦的靈活連接

Abstract

近年來由於線上遊戲，視訊會議，雲端電腦計算等等的普及，幾乎每個人都會有智慧手機和一台電腦，這些消費性產品在我們的生活中已經發揮了重要性，在這些消費性產品間靈活連接與提高資料傳輸對我們而言是非常需要的，在市場上，我們已經有很多諸如此類的通信解決方法，例如高速的USB 傳輸、近場通訊（NFC）、藍芽等。

在這篇研究中，我們發展了一個無線光通訊（OWC）來連接智慧手機和個人電腦之間的系統，首先利用光無線通訊中的紅外線數據協會（IrDA）訊號建立無線連接，這可以提供一個定向且安全的啟動通訊連接於特定的智慧手機和電腦。在通訊頻道被建立起來之後，無線傳輸（WiFi）連接的建立可以用來實現智慧手機和個人電腦之間的高速通訊，透過我們在電腦開發的軟體，可以將智慧手機的畫面投射到電腦螢幕上，在智慧手機上的操作可以透過電腦的鍵盤和滑鼠來實現，視頻和文件的傳輸可以輕易地使用拖拉來完成。 關鍵字：光無線通訊、安卓手機、紅外線、無線、USB

In recent years, due to popularity of online gaming, video conferencing, cloud computing, etc, nearly everyone has a smartphone and a computer. These consumer products have already played important roles in our lives. Flexible and high data rate communications among these consumer products are highly desirable. In the market, we have already witnessed solutions offering these communications, such as high speed universal serial bus (USB), near field communication (NFC), Bluetooth, etc. In this research, we develop an optical wireless communication (OWC) system connecting a smartphone and a personal computer (PC). The optical wireless connection is first established using Infrared Data Association (IrDA) communication. This can provide a directional and secure start-up link between a particular smartphone and a PC. After the communication channel is established, a wireless fidelity (WiFi) connection is built instead to achieve a high speed communication between the smartphone and PC. By using our developed software in the PC, the interface in the smartphone can be projected onto the PC screen. The operation of the smartphone can be done in the PC by using keyboard and mouse. Video and file transfer can be easily performed by drag and drop. Keyword: Optical wireless communication、Android mobile phone、Infrared、WiFi、USB
