上面這段影片是 Ryan Stewart 在 Adobe Max 義大利會場內拍回來的 demo 影片,主要是法國一家叫 Intuiface 的小公司用 air 做了個 multi-touch 的產品,而被大家驚為天人。(點上圖可看影片,brightcove 的 player 真威…)
這個 demo 有趣的地方在於:眾所週知的,air 並沒有 native support for multi-touch, 因此他們是怎麼做到的?
在影片的最後有回答這個問題,基本上一切都是自已來,從硬體(想必是塊多點觸控的面板),軟體(包含多點觸控 library & sdk) 與表現層(在這個例子裏是用 air client)。
看完影片後好奇去了該公司網站多瞄了兩眼,下面是他們的技術細節:
The IntuiFace platform comprises:
1. A large multitouch screen through which one or more users can interact simultaneously with their fingers, integrated into a variable-sized and custom-design furniture along with strong processing power, and many networking capabilities. Two levels of design and performance are currently offered (IntuiFace 1G and 2G).
2. A software middleware – the Multitouch Gesture Recognition Engine - that translates the multiple and simultaneous users’ touches into interaction gestures meaningful to the application. The Multitouch Gesture Recognition Engine also has the ability to connect with any existing application (such as GoogleEarth) by emulating the mouse and the keyboard.
3. A set of software components which provides a rich set of predefined capabilities for building truly multitouch, highly interactive and communicating applications using the Adobe’s AIR, Microsoft’s Windows Presentation Foundation or IntuiLab’s IntuiKit frameworks.
Examples of such components are: a virtual keyboard and touchpad, picture and video handling, office document manipulation, 2D/3D map and terrain navigation, etc. These components are highly customizable, in particular their graphical skins that can be tuned using products such as Adobe Illustrator or Microsoft Expression.
所以果然是三層式架構,只是其中所有苦力都要自已來,尤其是那個關鍵的多點觸控辨識器,但一旦這一層解決,下面的 air 表現層就容易了,大抵是乖乖接收各種事件然後做出反應,當然,多點觸控的操作模式下整體的介面設計、使用者經驗又是大不同,或許想成是一個 42″ 的超大 iphone 躺在前面,而且有 4-core cpu 外加超強 multi-tasking,這樣就很接近了 XD
另外目前硬體有兩種,如下圖(好奇的是,台灣眾多代工廠何時能量產這玩意?還是已經有了?價格如何?):

影片最後他也提到這套系統不是只能在 windows 上跑,將來也可以在 netbook 與手機上執行,因此,理論上,像 iphone, palm pre 這樣的多點觸控介面日後一般人也可以自已來,我覺得台灣一票 netbook 廠商既然現在已經想再朝 tablet 方向發展一次,不如就直接整合多點觸控,然後好好搭配軟、硬體弄出一套方便的 solution,不論是要看電子書、上網、簡報等,應該可以玩出不同的格局,不然 netbook 這波的趨勢看來很快又要搞成價格戰,最後不但沒人獲利,還打到自家 laptop 銷量,得不償失呀…
btw, 最後我也跑去看了一下 microsoft surface,但目前似乎也沒什麼動靜,到底還有沒有在發展啊?
附帶一提,這篇文章是在 wordpress 2.7 裏編輯的,新版介面真正是越改越難用,很不容易的成就吶
