The objective of the study is to examine the acceptance and usability of Augmented Reality (AR) visuals developed for industry analysis of Thai Banks and whether these visuals can outperform the table of numbers in representing financial accounting data. Convenient samples were used and the data were collected with self-assessed questionnaires from 109 users with minimum prior experiences with financial analyses. The results from descriptive statistics indicates that despite having over 80% of respondents with little prior experience in analyzing financial performance of banking industry, the majority of them were able to correctly make prediction (96.4%), identify trend (82.6%) and compare banks' performance (70.6%). Their attitudes and perception towards Bank-AR visuals were above average. Although the overall usability score is average (53%), the respondents rated the Bank-AR visuals to be highly useful and had high intention to use them in the future.

This paper proposes an augmented reality technique to generate acrobatic scenes from hitting motion videos. After a user shoots a motion that mimics hitting an object with hands or feet, their pose is analyzed using motion tracking with deep learning to track hand or foot movement while hitting the object. Hitting position and time are then extracted to generate the object's moving trajectory using physics optimization and synchronized with the video. The proposed method can create videos for hitting objects with feet, e.g. soccer ball lifting; fists, e.g. tap ball, etc. and is suitable for augmented reality applications to include virtual objects.

With the advancement of information technology, the application of augmented reality (AR) in dentistry is an emerging research field of image-guided surgery and dental education. In addition, the digital approach to incorporating AR in dental practice management is considered to be feasible. A prototype is developed to apply AR to dental daily clinical practice in order to help dentists to access electronic dental records. This prototype delivers patients' information and related clinical data to dental clinicians directly without the need to search for the appropriate patients. Wearable AR devices are considered to be a convenient tool for practicing dentists because dental practitioners are not always able to use a computer during active clinical sessions, such as implant placement, root canal treatment, and patient-doctor communication. The use of AR to visualize passive transferred patient data would be valuable for practicing dentists.

A simulator in Android is developed for Qualcomm Augmented Reality (QCAR) software development kit (SDK). The main purpose is to replace the testing of application on actual Android device. Bugs in the application can be found easily when testing is done in the simulator (with support of Android emulator) before the testing on real device. The simulator does not require a camera in testing augmented reality application. Works included study on QCAR SDK's behavior is done to ensure that the simulator performs similar to the SDK. Description on how would the simulator works with QCAR SDK is included in the paper.

As a new hybrid broadcasting service, augmented broadcasting shows enhanced broadcasting content on a large TV screen, while augmented reality (AR) on a mobile device augments additional graphical content onto an input image from the device's own camera to provide useful and convenient information for users. A one-sided broadcasting service using AR has already been attempted in virtual advertisements during sport broadcasts. However, because its augmentation is preprocessed before the video image is transmitted, the viewer at home may have no influence on this formation; and no interaction for the user is possible unless the viewer has a direct connection to the content provider. Augmented broadcasting technology enables viewers to watch mixed broadcasting content only when they want such service and to watch original broadcasting content when they do not. To realize an augmented broadcasting service, the most important issue is to resolve the hybrid content synchronization over heterogeneous broadcast and broadband networks. This paper proposes a novel hybrid content synchronization scheme for an augmented broadcasting service and presents its implementation and results in a terrestrial DTV environment.

The purpose of this research is to examine the user experience design that effectively exhibits botanical information through a virtual habitat built with 3D modeling and scanning data for the conservatory at Seoul Botanic Park. Seoul Botanic Park's conservatory contains environmental and ecological information on the wide spectrum of diverse plants under twelve cities all over the world. However, the exhibition method, which focuses on maps and information boards, has limitations in delivering diverse plant and habitat information to visitors. Virtual and augmented reality can be used as an effective tool for educating and experiencing the contents of various plant species as it can convey the ecological and environmental conditions of the habitat and local culture at diverse levels. This study experimented with constructing virtual habitats using the Unreal Engine and effectively communicating various botanical information through the interaction. With the introduction of a virtual habitat, we intend to enhance the user experience of park visitors and ultimately explore the possibility of using virtual and augmented reality to convey multi-layered environmental and ecological information of landscape.

최근 교육의 학습 효과에 도움을 제공하기 위해 실감 콘텐츠 환경에서 상호작용을 제공하는 시스템이 널리 활용되고 있다. 특히, 증강현실(Augmented reality) 기술은 실제 학습 환경에 가상의 물체를 합성하여 정보를 직관적으로 이해하는데 도움을 제공할 수 있다. 본 논문에서는 기하와 관련된 입체도형에 대한 수학개념을 3차원의 공간 정보를 이용하여 학습하는 증강현실 도구를 개발하였다. 이를 위해 수학 교육 과정 중 각기둥과 각뿔에 관한 교과서에 증강현실 합성 기술을 적용하여 공간적인 학습 효과를 보다 높일 수 있도록 하였다. 또한, 카메라와 마커 사이의 위치 관계에 의해 정합이 되도록 가상의 도형을 표현하였고, 공간에 대한 지각 효과를 높이기 위해 평면도, 전개도 등 도형 형태의 다양화, wireframe 가시화 모드 선택 기능 등이 가능하도록 하였다. 본 논문에서 제시한 증강현실 기반 학습도구를 통해 수업에 관한 학업성취도 및 흥미도에 관한 효과성을 평가한 결과 통계적으로 유의한 결과를 얻을 수 있었다. 본 논문에서 제안한 방법을 통하여 입체도형 학습 뿐 아니라 다양한 수업에서 교육적 효과를 높일 수 있을 것으로 전망한다.

Recent advanced interlace technologies allow the user to interact with different spaces such as Virtual Reality (VR), Augmented Reality (AR) and Ubiquitous Computing (UC) spaces. Here, we present a LEGO House application, a collaborative application which involves multi interaction spaces -VR, AR and UC spaces. The LEGO House application is built based on the VARU framework which is designed for enabling the prototyping of a tangible space application. The application is about an interior design. One user is located in the combined AR and UC space and interacts with the AR LEGO house and the physical smart devices. The other users interact with the virtual LEGO house but they share the same environment, the LEGO house. Therefore, they can collaborate together as they are co-located.
