洪一平臺灣大學：資訊網路與多媒體研究所賈義偉Chia, Yi-WeiYi-WeiChia2007-11-272018-07-052007-11-272018-07-052007http://ntur.lib.ntu.edu.tw//handle/246246/58415在這篇論文中,我們提出一個使用背部投影的互動式多重解析度桌面顯示系統,簡稱i-m-Top。 這個桌面系統目標是能幫助使用者執行一般的長時間工作，像是文件的讀寫或是進行大量資料的瀏覽及詳細檢索。 所以i-m-Top的設計需要達到以下四個要求: (1) 要能在桌面顯示上提供可控制的高解析度呈像，(2) 提供直覺的互動方式並能做精密的控制，(3) 使用者長時間使用的舒適度，(4) 設置上要能使之像是一個日常生活中的數位家俱。 因為這些要求，我們採用多重解析度顯示與多重解析度互動方式來幫助使用者執行各式各樣的工作。 我們將會介紹整個系統的架構，以及顯示與互動的方法，並討論i-m-Top如何達到以上提及的重點。我們在i-m-Top上實作了兩個應用。第一個應用是一個可讓使用者在i-m-Top上執行平日的數位文件工作，第二個應用則是提供一個影片檢索的使用者介面。我們將會介紹i-m-Top如何使這些應用能更加便利，以及它們的內容、放置方式、互動方式都也將會被詳細敘述及討論。In this paper we proposed the i-m-Top, an interactive multi-resolution tabletop system with rear- projection. The aim of the table is for a user to perform regular and long-term works such as reading and writing documents or browsing and checking a large amount of information. So, the design of i-m-Top meets the following concerns: (1) a controllable high-resolution perception of the tabletop display, (2) intuitive interaction and precise manipulation, (3) Comfort for long-term using, (4) Physical setup as furniture in our daily life. Because of the concerns, the multi-resolution display and interaction are adopted to help the user do various tasks. We will articulate the system architecture and methods for display and interaction of i-m-Top and how the system, i-m-Top, achieves the concerns mentioned above. There are two applications implemented in i-m-Top. The first One is for the user to do his or her daily tasks manipulating the digital documents. The other one is a user interface for video retrieval. We will introduce how the applications are benefited by i-m-Top, and the detail of the content, layout, and interaction will be discussed.1 Introduction [1] 2 Related Work [4] 2.1 Touch Detection [4] 2.2 Multi-resolution Display [6] 2.3 Applications of Tabletop System [7] 3 System Design [9] 3.1 The concerns of design [9] 3.2 Implementation [11] 3.2.1 Devices for display [11] 3.2.2 Devices for input [14] 4 Multi-resolution Display [16] 4.1 Transformation of Coordinates [17] 4.2 Display Calibration for Projectors [19] 4.3 Run-Time Execution [21] 5 Multi-resolution Interaction [23] 5.1 Fingers and Palms Detection [23] 5.1.1 Finding fingertips [24] 5.1.2 Finding palms [27] 5.1.3 Allocating fingertips to corresponding palms [27] 5.1.4 Defining the events [28] 5.2 IR LED Pen [28] 5.2.1 Pen tip detection [29] 5.2.2 Priority of pen and palms [29] 6 Applications [31] 6.1 User Interface for Browsing and Editing Digital Documents [32] 6.1.1 Motivation [32] 6.1.2 Content and layout [32] 6.1.3 Interaction [32] 6.1.4 Experiments [33] 6.2 User Interface of Video Retrieval System [35] 6.2.1 Motivation [35] 6.2.2 Content and layout [36] 6.2.3 Interaction [36] 7 Conclusion and Future Work [39] 7.1 Conclusion [39] 7.2 Future Work [40] 7.2.1 Direct-Touch detection [40] 7.2.2 Multi-resolution detection for the pen tips [40]1144442 bytesapplication/pdfen-US背部投影多重解析度互動式桌面系統rear projectionmulti-resolutioninteractive tabletop systemthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/58415/1/ntu-96-R94944021-1.pdf
