College of Internet Distance Educationg Assumption University of Thailand poonsri.vate@gmail.comAbstract— This article presents the the AR technology involves the exhibit andimportant foundation of Augmented manipulation of 2D and 3D objects. The realReality (AR) technology. Its main images or 3D and the text of AR applicationobjective is to envision the past, present appear on the computer screen when theand future of Augmented Reality camera device installs the software bytechnology. Augmented Reality capturing the marker through Radiotechnology especially on the mobile device Frequency Identification (RFID) [1].

INTRODUCTION nearly as old as the entire computer graphics This paper focuses on basic knowledge and field itself [2]-[3]-[4]-[5]. AR is ‘the virtualinformation about Augmented Reality (AR) augmenting the real’. Augmented virtually iswhich will be universally used in the future when ‘the real augments the virtual’ [6].

  2. 2. Poonsri Vate-U-Lan, Ed.D. According to data on Google Insights for Augmented Reality, and level three -Search (Figure 1), from 2009 AR has Augmented Vision [4]. Based on Figure 2,become a more common topic in both search the levels of AR can read from right to left,volume index terms and news reference level zero - physical world hyper linking,volume than VR. This result seems to reflect encompassing the oldest form which was athe ubiquitous growth of mobile technology way to link the physical world to the virtualas well as featured camera technology and world [9].the ease of touch screen mobile phones withGlobal Positioning System (GPS) such as theiPhone and Android phones as the mainfactors in the development of AR projects.AR will be widely used for educationalpurposes within 2-3 years as reported by the2010 Horizon Report, an annual report onmodern learning and teaching technologies.This report was first issued in 2002 by theNew Media Consortium and theEDUCAUSE Learning Initiative [7]. In order to produce the AR projects forspecific purposes, there are many aspectsthat require consideration and planning. The Figure 2.

The driving the popularity of markerless AR wasmarker based AR is the most exciting GPS and its compass which is common ininnovation for an amateur user since it is smart phones. The AR application on thefascinating to see 3D objects superimposed phone recognized the position of GPSon the marker [1]. The cooler marker was a followed by capturing the direction based on3D recognition when the camera captured the compass, then augmenting the 3D orthe recognized physical objects such as an information on the screen correctly (Figureapple, or a chair and then with the focus 8). The markerless AR using GPS still hasmaintained on the object to augment a 3D some challenges to overcome since GPS isanimation (Figure 7) [9]. The marker enabled probably only accurate to within 9 metersreal time processing of ‘reality’ and (30 feet) and does not have enough accuracysubsequently real time rendering and display indoors, although improved imageof graphics and the 3D model on top of its recognition technology may be able to helpreality. This level one marker based AR [15].became ubiquitous in 2011 in both onlineand offline mode. The main reason insupport of this level one was due to itproviding the increased opportunity ofproduction which offered both free and opensource code along with “fancy” or elaboratecommercial software. Moreover, itspopularity became realistic since ARtechnology can be viewed through the AdobeFlash Player. Another reason why the marker Figure 8.

The factor increasing theInterface Technology Center, University of growth of AR is its ease of use.Washington, invented the special contactlens (Figure 9) that introduced the AR IV. FACTS ABOUT AUGMENTED REALITYtechnology into the human eye [16]. The lens AR is in high demand not only forused sensors and wireless technology to educational purposes but also has becomeallow bionic eyesight. People who wore this important for strategies in advertising andAR contact lens were able to monitor their marketing. The commercial software of theheart by making use of tiny circuits and AR creator is very advanced but definitelyLight-Emitting Diode (LEDs) [16]. The expensive. This has become an obviousresult of the first Augmented Vision product obstacle given the very few open sourceswill revolutionize medical science in many available. Thus, two main concerns whenaspects. The example of simulation for a user constructing AR projects are: 1) the need ofwho wears Augmented Vision will see more an expensive budget to deal with numerousinformation of any object already technical complexities involved in the longprogrammed as revealed in Figure 10. This process of production and 2) theidea of Augmented Vision has been development and planning of a qualitypresented before the complete technology analysis phase to ensure an acceptablewas developed and appeared in the fantasy quality level and a return on investment [18].film “The Terminator”. Augmented Vision The potential of AR technology towas in high demand to be developed and influence people’s behavior as shown in theresearched not only in the academic field but research that about three quarters (74%) ofalso in other fields especially commercial parents who experienced a toy demonstrationentertainment. via AR considered buying the product but less than half (45%) who viewed the 2D paper-based demonstration considered buying the same product [19]. AR technology has been used to support marketing in various ways and the most popular is an integration of AR technology on brochures (Figure 11). Figure 9. Augmented vision, source [16] Figure 11. How AR is being used, source [20] V. CONCLUSION AR technology will be used to contribute to smart innovation projects in the future because of its potentials and fascination. The usefulness of AR technology encourages researchers and programmers to create innovative products which should make life Figure 10.
