使用可感測方位的手持式設備從事人機互動之研究

Abstract

近年來，人機介面的設計已成了當紅的研究主題，本論文旨在探討如何使用可感測方位的手持式設備從事人機的互動，以及其未來有可能的應用範圍。我們利用手持式設備搭配電子羅盤，對環境的互動以及大型螢幕的互動提出的嶄新的互動方式。在環境互動的方面，我們利用環場技術作為使用者與其環境溝通的介面，藉著方向感測器的幫助，我們可自動調整環場方向，使之與真實環境一致，提供使用者一個更直覺的瀏覽方式，對於系統的實用性及接受度，我們做了一系列的實驗，證明了未來可望用在e-home或博物館導覽上。在大型螢幕互動方面，我們實作了兩個應用：環物控制器以及留言版，環物控制器可讓使用者以更直覺的方式操縱大型螢幕上的環物影像，如同有親自把玩環物的感覺。留言版則是利用手持式設備上的小型螢幕和大型螢幕互動的應用，讓使用者可自由的在大型螢幕上留言。

This thesis presents an orientation-aware handheld for human-computer interaction, which is a popular research field in recent years. To acquire orientation information, we equip a handheld with an orientation sensor. With this handhelds, we design a panorama-based interface for users to interact with the physical environment. A panorama of the environment is displayed on the handheld device and is automatically aligned with the real world. A user can interact with objects within the environment by selecting the corresponding items on the display. Seeing the same scene on both the handheld and the real world, users quickly and accurately can select items. A prototype system is implemented and the user study is also conducted to demonstrate the system in e-home and museum guide applications. In addition to the interaction with the environment, our orientation-aware handhelds can also be used to interact with large displays. We develop two applications to proof that our handheld can provide an intuitive and effective method of interacting with large displays.
