互動式多重解析度柱狀顯示系統

隨著顯示科技及輸入技術的發展，許多研究致力於新型態指觸人機互動技術的開發，將電腦引入日常生活的數位裝置越來越受注目。基於圓柱系統的需求，我們發展了八面玲瓏柱— 一個使用背部投影的互動式多重解析度圓柱顯示系統。這個圓柱顯示系統目標是能讓在系統四面八方的人能同時看到資訊，並且採用多重解析度顯示與多指觸控的互動方式來幫助使用者操作，這個系統的設計需要達到以下三個要求：(1)要能在圓柱顯示上提供可控制的高解析度成像，(2)提供直覺的觸控互動方式並能作精密的控制，(3)使設置像是一個現實生活中能實用的數位裝置。在多重解析度方面，我們設計了符合人類視覺特性的顯示方式，結合一台可控制方向的投影機及四台廣角投影機，僅在使用者感興趣的局部區域提供高解析度的投影畫面，而在其他的區域則僅提供較低解析度；多指觸控方面我們利用紅外線攝影機及紅外線照射燈，透過影像處理的方式進行手指的偵測及追蹤。然而我們將介紹整個系統的架構，以及顯示與互動的方法，說明圓柱裝置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，也將會被詳細敘述及討論。

In this paper, we proposed a new structure reference as the i-m-Tube to realize an unobstructed 360° multi-resolution information display and multi-touch interaction. The goal of our system is not only suitable for displaying panoramic contents, but also possible to create an intuitive and natural context for multi-user interaction with multimedia content displayed on the i-m-Tube by touch. So, the design of the i-m-Tube meets the following concerns: (1) a controllable high-resolution perception of the tubular display, (2) intuitive interaction and precise manipulation and (3) physical setup as device in our daily life. The high-resolution display is achieved by combining one steerable fovea projector and four peripheral projectors. The large-ranged touch-sensing is based on diffused illumination/FTIR and analyzed by computer vision technology. With a preliminary experiment of the applications on the i-m-Tube, it is exciting to see the i-m-Tube as a new interface for people to meet the interactive multimedia touch in this generation.
