3. Definition
1990 The term augmented reality (AR) was originated
by scientists at the aircraft manufacturer Boeing.
1994
Milgram and Kishino presented the concept of a
virtuality continuum.
1997
Azuma identified three characteristics of AR .
1. Combines real and virtual
2. Interactive in real time
3. Registered in three dimensions
TIMELINE
4. Image Recognition and Location
• The two types of AR application
reported in Pence’s (2011) study,
namely:
• Kun-Hung Cheng and Chin-Chung
Tsai attempts to re-coin the two types
of AR as :
(1) image-based
(1) marker-based
(2) markerless
(2) location-based

5. Display Technologies
• There are two ways to accomplish the combining of real and virtual
: video or optical technologies.
Video Optical
The video cameras provide the user's
view of the real world.
The user can look directly through
optical combiners to see the real world.
in the 1990s, the term augmented reality (AR) was originated by scientists at the aircraft manufacturer Boeing, who were developing an AR system thatblended virtual graphics onto a real environment display to help aircraft electricians with cable assembly (Caudell and Mizell 1992).
波音公司研究與技術部門的工作人員表示,他們利用谷歌眼鏡製造出了飛機的電子線束。
波音公司表示, 他們使用谷歌眼鏡後安裝電子線束的時間縮短了25%, 同時錯誤率降低了一半。
由於飛機包含了連接到電力系統的凌亂、巨大及複雜的電線網絡,技術人員需要一邊觀看筆記本電腦上的PDF組裝說明,一邊手動安裝,用AR眼鏡代替電腦屏可以為工作人員帶來不少方面。原文網址:https://kknews.cc/tech/axayog.html原文網址:https://kknews.cc/tech/axayog.html原文網址:https://kknews.cc/tech/axayog.html
