          基于多點觸控技術的辦公桌

          —— ——2008年英特爾杯大學生電子設計競賽嵌入式系統(tǒng)專題邀請賽作品簡介

                  多點觸控技術作為一項新技術,完全改變了人與電腦的交互方式。但基于此技術的軟件產(chǎn)品和應用還較少。本作品基于多點觸控技術,利用“嵌入之星”開發(fā)平臺,構建了一個集個人信息處理與多人會議功能的辦公桌平臺,面向廣大的辦公室人群。此辦公桌最大的特點是同時支持多個輸入,即多人交互可以在一個辦公桌上完成,極大的方便了辦公室人群。

                  本系統(tǒng)搭建了基于DI技術的辦公桌,內(nèi)嵌高分辨率攝像頭捕捉多指觸控的圖像信息,再利用酷睿雙核CPU的高性能特點進行圖像處理,得到一系列用戶操作消息。辦公桌內(nèi)嵌的投影儀使得桌面可實時顯示用戶操作的內(nèi)容,整個桌面就相當于一個超大的觸摸屏。軟件部分,本小組自行設計了基于多點觸控消息操作的辦公軟件,支持四人同時操作。軟件包含了繪圖、寫字、日程表、通訊錄、發(fā)電郵等辦公功能,也包含了圖片瀏覽、視頻瀏覽、小游戲等娛樂功能。這些軟件聽名字都很常規(guī),但是用戶操作方式的創(chuàng)新使其擁有更多易用的特性,以前多次的鼠標點擊的效果現(xiàn)在也許只要兩個手指的拖動就能實現(xiàn)。

          As a brand new technology, Multi-Touch has changed the way people interact with computers completely. But the software products based on such technology has not been developed much. Our product is based on Multi-Touch technology and the “Embedded Star” platform, it is an office table which is able to process personal data and hold office meetings. The key feature of the desk is supporting multiple inputs, which means four people can work on the same desk simultaneously, which greatly facilitates their work.

          This system consists of a desk with DI (Diffused Illumination) technology, and a high-resolution video camera to capture the image of finger touch, and Core Duo CPU to process the image, in order to translate the light blob images into the messages that users send to the system. The desk is embedded with a projector so that everything is displayed simultaneously on the surface of the desk. This makes the desk a huge touch screen. As for the software, we designed a set of office tools based on Multi-Touch operations, which makes it possible for four people to work on the desk at the same time. The office tool includes paint, words, calendar, address book, email; there are also entertainment parts such as image browsing, video playing, and fancy little games. These software sound familiar, but as the finger interaction is introduced, they have become easy to use, some operations involving several mouse clicks may be replaced by two fingers dragging.
