以觸控式行動裝置為基礎之指向互動系統

Abstract

本篇論文旨在標準觸控式行動裝置上，提供了一個直覺、有彈性的傳輸配對之解決辦法，只要透過指向對象的簡單動作即可完成。當使用者想與附近的觸控式行動裝置進行傳輸前，雙方只要在螢幕上相互對著傳輸對象的方向，執行簡單的指向動作後，便能得到使用者的選擇對象位置並完成配對。此系統之優點在於以使用者直覺操作為基礎而進行配對傳輸，並降低使用者在傳輸前配對上的繁雜工作，只需利用觸控式行動裝置中的觸控感應器和方位感測器，即可實作上層的應用程式並且在觸控式行動裝置上執行。此外，相較於大部份配對研究只著重於一對一的配對，我們更進一步設計了一對多、多對多的配對方式，並在觸控式行動裝置上有效的運作，未來亦可進一步在其它功能相近的行動裝置上使用，且不需要特別的輔助裝置。最後，本研究已在Android系統上，實現一個創新的數位名片交換的應用，並說明本系統是一個直覺且方便的裝置間配對的應用。

In recent years, mobile devices are embedded many sensors which emerge as a possibility to create applications for facilitating the daily life of mobile device users. Device pairing is the initial and essential step for constructing the connections among the devices, which is required by many mobile device applications. Traditionally, the users have to do this device pairing procedure manually and the “perception gap” problem results in the difficulty of device pairing. In this paper, an intuitive pairing interaction system is developed by using the touch-enabled mobile devices embedded with the orientation sensor. The basic idea of operating this system is based on a simple point action on the touch screen when the users intent to pair their mobile devices with nearby users. Then, the system identifies the pairing target users through an authentication procedure. Previous works are focus on one-to-one pairing and external sensors are needed in some works. In this system, the device pairing modes of one-to-one, one-to-many and many-to-many are all considered. The system can be effectively implemented on mobile devices with the touch screen and the orientation sensor, which are common features of commercial off-the-shelf smartphones. Moreover, an innovative digital name card exchanging system is implemented on Android mobile phones to demonstrate that the smartphone users could exchange their name card with each other through a simple point action without a centralized cloud server.
