In recent years, large-scale and high-density use of LED on facades has exposed some disadvantages, such as light pollution, high energy consumption, unsustainability, and poor interactivity. Because of the development of smartphones and augmented reality (AR), AR has emerged as a new technology available to users to interact with the media façade. As an augmented reality app for public space, the AR map app can superimpose virtual images on the surface of a building to form an AR media façade, which can be applied in the fields of navigation, advertising, interactive public art, smart retail, etc. This study establishes the variables influencing usage intention and the consequent outcomes of Huawei AR map app and uses the technology acceptance model (TAM) to discuss their relationship. Results show that consumer innovativeness, information quality, and design quality have a strong influence on perceived ease of use. Information quality has a positive impact on perceived usefulness, but design quality has a weak influence. Also, the design quality of Huawei AR map app and consumer innovativeness have a higher effect on perceived enjoyment than information quality. Users' usage attitude and perceived usefulness when using Huawei AR map app are key factors determining their usage intention. This study inspires city planners, architects, developers, and designers of AR apps that augmented reality can partly replace media façade, and that investment in augmented reality will achieve significant sustainable economic and social benefits.

A spatial augmented reality (SAR) system enables a virtual image to be projected onto the surface of a real-world object and the user to intuitively control the image using a tangible interface. However, occlusions frequently occur, such as a sudden change in the lighting environment or the generation of obstacles. We propose a robust object tracker based on a multithreaded system, which can track an object robustly through occlusions. Our multithreaded tracker is divided into two threads: the detection thread detects distinctive features in a frame-to-frame manner, and the tracking thread tracks features periodically using an optical-flow-based tracking method. Consequently, although the speed of the detection thread is considerably slow, we achieve real-time performance owing to the multithreaded configuration. Moreover, the proposed outlier filtering automatically updates a random sample consensus distance threshold for eliminating outliers according to environmental changes. Experimental results show that our approach tracks an object robustly in real-time in an SAR environment where there are frequent occlusions occurring from augmented projection images.

The purpose of the present study was to explore the development of knowledge about the appearance-reality distinction and its relation to children's developing theory of mind. The subjects were 90 children, 15 boys and 15 girls each at the ages of 3, 4, and 5. The performance of the appearance-reality distinction was compared on illusory object, color, pretend event, and picture tasks. The data were collected by individual testing and analyzed by two-way ANOVA with repeated measures. The results showed that there were significant differences between 3-and 4-year-olds in the appearance-reality distinction, while there was no significant difference according to gender or type of tasks. It was also found that children at the age of 3 and 4, committed phenomenism errors more often than intellectual realism errors, while 5 year olds did not show particular differences.

The virtual reality technology has been developed as the computer and computer graphic technology are progressed. However it has still the limits of the use because of it costs a great for system construction. A virtual reality technology is the best application example to reduce time and cost of development in engineering. Actually, VR(Virtual reality) technology has given engineers the ability to design, test and evaluate engineering systems in a virtual environment. The objective of this paper is to construct the arm mounted display VR system by using 3 channel spherical screen and to show its capabilities of an engineering system development. This paper describes the development of arm mounted display VR system with 3 channel spherical screen system and the generation of 3 channel graphic modules. The arm mounted display VR system provides a highly economical efficiency because of it uses a popular computer system as a graphic server.

Detecting marker coordinates is important in augmented reality system based on tag. If a marker is not detected, objects can't be augmented. In this paper, we propose a noise reduction method for augmented reality. Using a blue color space to HIS color transformation was performed on the binary. Erosion operator and the dilation operator of the binary images were performed. Experimental results show that proposed method produces a tag image recognizable in various light environments. And using the area of the rectangle, the labeling could be detected through the tag. Tag recognition rate is improved by removing noise.

David Simon's critically acclaimed HBO series, The Wire (2002-2008), has frequently been termed "Dickensian" for its ambition to present urban social reality in its totality. Primarily focusing on the fourth season, which offers a wide-lens, deeply contextualized investigation into Baltimore's failing public school system, I interpret the show intertextually to discern its different forms of urban pedagogy. With Dickens's Hard Times and other narrative intertexts, I argue that The Wire, with its "Dickensian" attentiveness to the relations of part and whole, attachment and detachment, foregrounds the act of reading and misreading social reality. This is fundamentally a pedagogic process, positioning its characters and viewers as "students," imparting to them lessons in critical thinking. The knowledge gained is largely negative; nevertheless, teaching The Wire in a Korean university has revealed its efficacy in provoking student-viewers to critical reflection on urban social reality and their own positionality.

Augmented Reality (AR) is an emerging technology and a vibrant field, it has become common in application development, especially in smartphone applications (mobile phones). The AR technology has grown increasingly during the past decade in many fields. Therefore, it is necessary to determine the optimal approach to building the final product by evaluating the performance of each of them separately at a specific task. In this work we evaluated overall CPU and RAM performance for several types of Markerless Augmented Reality applications by using a multiple-objects in mobile development. The results obtained are show that the objects with fewer number of vertices performs steady and not oscillating. Object was superior to the rest of the others is sphere, which is performs better values when processed, its values closer to the minimum CPU and RAM usage.
