工研院(ITRI)開發(fā)出一款i-Air Touch (iAT)智能眼鏡，乍看之下有點像是頭戴式3D View-Master照片觀賞器，但這款采用Air Touch 凌空觸控技術的突破性智能系統(tǒng)可追蹤手勢動作，從而觸控激活用戶與3D視覺頭戴式顯示器的互動。 i-Air Touch頭戴式顯示器藉由分別為用戶的眼睛提供左右不同影像的方式，從而在用戶面前約30公分(12 英寸)處投影一個3D虛擬影像。i-Air Touch還結合安裝在眼鏡上的相機，可追蹤用戶的手勢動作，使其可透過觸控方式與虛擬顯示器進行互動，在技術上還比Google Glass更勝一籌。 工研院聲稱其i-Air Touch是首款可實現(xiàn)讓用戶以觸控方式隨意與虛擬影像互動的透明頭戴式顯示器。用戶只要使用與在一般觸控屏幕上相同的手勢即可，如揮手換頁、兩指放大縮小，以及在虛擬鍵盤上輕點選取輸入等，而且僅限于穿戴上這款智能眼鏡的人才能看到。由于眼鏡是透明的，用戶在穿戴上后仍可自在地行走、導航以及與他周遭的人事物進行互動。

i-Air Touch頭戴式顯示器讓用戶可觸控激活懸浮于半空中的虛擬屏幕

安裝在眼鏡上方的相機鏡頭采用工研院自有的 DDDR相機，以達到毫米級的精準度來追蹤手勢動作，用戶可經(jīng)由觸控方式與懸浮于半空中的虛擬顯示影像互動。由于這款 DDR 相機用相位編碼(實現(xiàn)距離)與色彩編碼(確認指尖位置)，因此只有在用戶的指尖進入眼鏡前28-32公分范圍內(nèi)時，它才能感應到觸控輸入。 而當用戶指尖離開此范圍內(nèi)時，該相機還會關閉辨識電子裝置作業(yè)，從而節(jié)省電池電量。一旦DDR相機偵測到觸控輸入，即傳送一個信號至主應用處理器以確認用戶手指的動作，讓用戶得以與虛擬屏幕互動。 i-Air Touch 凌空觸控技術采用模塊化建置，使其三項主要組件──透明眼鏡顯示器、 3D DDDR相機以及 Air Touch 凌空觸控互動軟件──可分別與其它可穿戴式系統(tǒng)整合。工研院聲稱，該研發(fā)團隊目前正致力于縮小相機模塊使其得以整合于智能眼鏡的掛耳部份，從而改善i- Air Touch 眼鏡目前看來較笨重的外觀。i-Air Touch 的所有相關技術均出自工研院，目前已可授權給電子OEM 。 這款i-Air Touch頭戴式顯示器將在11月獲頒2013百大科技研發(fā)獎( R&D 100 Award)。 本文授權編譯自EE Times，版權所有，謝絕轉載 編譯：Susan Hong 參考英文原文：Wearable Display Goes 1 Step Beyond Google Glass，by R.

{pagination} Wearable Display Goes 1 Step Beyond Google Glass R. Colin Johnson PORTLAND, Ore. — Looking a bit like a head-mounted View-Master, the i-Air Touch glasses from the Industrial Technology Research Institute (ITRI), of Hsinchu, Taiwan, is a breakthrough system that tracks hand movements to enable touch-activated interaction with a 3D virtual head-mounted display. The i-Air Touch glasses will receive a 2013 R&D 100 Award on Nov. 7 in Orlando, Fla. The i-Air Touch glasses project a virtual 3D image about 30 centimeters (12 inches) in front of the user by supplying separate left and right images to the user's eyes. Going one-step beyond Google Glass, the i-Air Touch also incorporates cameras mounted above the glasses to track the user's hand movements to enable him to perform touch-activated interaction with the virtual display. ITRI, Taiwan's largest independent research lab, claims its i-Air Touch technology realizes the world's first see-through, head-mounted display that allows users to freely interact with it using touch. The user can use all the same gestures used on a normal touchscreen, such as swiping to change pages, pinching to zoom, and tapping to select entries on a virtual keyboard, all of which is only visible to the person wearing the glasses. And since the glasses are see-through, the user can still walk, navigate, and interact with objects and people in her surroundings. The i-Air Touch interface allows users to touch activate virtual screens floating in mid air. The camera mounted above the glasses uses ITRI's own DDDR (defined distance with defined range) camera to track hand movements with millimeter accuracy, allowing the user to use touch to interact with the virtual display in the same manner as if a touch screen were floating in mid-air. Because the DDDR camera uses both phase-coding (for distance) and color-coding (to identify fingertips), it will accept touch input only when the user's fingers are within a range of 28 to 32 centimeters (11 to 12.5 inches) in front of the glasses. To conserve battery power, the camera shuts down the recognition electronics whenever the user's fingers are not within that range. Once detected within range, the DDDR sends a signal to the host application processor identifying the user's finger movements, allowing him to interact with the virtual display. The i-Air Touch technology is modular, allowing its three components -- the see-through glasses display, the 3D DDDR camera, and the air-touch interactive software -- to be separately integrated with other wearable systems. ITRI claims that it is currently downsizing the camera module to fit into the ear-pieces of its eye-glasses, to eliminate the bulky look of the i-Air Touch glasses. As with all ITRI's technologies, the components of the i-Air Touch technology are available for licensing by electronics original equipment manufacturers.
