Modern technology offers many ways to enhance teaching and learning that in turn promote the development of tools for educational activities both inside and outside the classroom. Many educational programs using the augmented reality (AR) technology are being widely used to provide supplementary learning materials for students. This paper describes the potential and challenges of using GeoGebra AR in mathematical studies, whereby students can view 3D geometric objects for a better understanding of their structure, and verifies the feasibility of its use based on experimental results. The GeoGebra software can be used to draw geometric objects, and 3D geometric objects can be viewed using AR software or AR applications on mobile phones or computer tablets. These could provide some of the required materials for mathematical education at high schools or universities. The use of the GeoGebra application for education in Laos will be particularly discussed in this paper.

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.

This case report describes a dynamic digital esthetic rehabilitation procedure that integrates a new three-dimensional augmented reality (3D-AR) technique to treat a patient with multiple missing anterior teeth. The prostheses were designed using computer-aided design (CAD) software and virtually trialed using static and dynamic visualization methods. In the static method, the prostheses were visualized by integrating the CAD model with a 3D face scan of the patient. For the dynamic method, the 3D-AR application was used for real-time tracking and projection of the CAD prostheses in the patient's mouth. Results of a quick survey on patient satisfaction with the two visualization methods showed that the patient felt more satisfied with the dynamic visualization method because it allowed him to observe the prostheses directly on his face and be more proactive in the treatment process.

The "AR Campus Diary" project innovates in the realm of art through integrating augmented reality (AR) with interactive storytelling, fostering personal and interpersonal development through artistic expression. This artistic endeavor metaphorically represents the growth and fruition of individual stories, facilitated by a series of progressive art activities that emphasize continual interaction between self and others. Set against the backdrop of a university campus, the project employs AR markers designed to unfold stories in phases through a dedicated application, allowing participants to experience and influence the narrative uniquely. Diverging from traditional film editing techniques, "AR Diary" offers viewers the autonomy to navigate through story segments of their choosing, marking a departure from conventional cinematic storytelling by leveraging marker-based plot progression. This project not only showcases the fusion of technology and art but also pioneers a participatory form of art education based on engagement and play.

Digital convergence era has been already started and is rapidly developed. Recently, convergency technology became an essential issue in all industries, and is expected to accelerate. This means that we can experience growth and change of architecture using new technology and approaching method. The AR (Augmented Reality) technology, among these convergence technology, is a kind of virtual reality technology that user can see a scene of real world which is overlapped by virtual world with additional information. It has been used in manufacturing and management in the whole industry fields including medical, mechanical, military field and so on because it can provide higher sense of reality. Thus, in this paper, we suggest the utilization of AR technology for organically connecting the roads, facilities, green area, landscape and others in the layout planning of housing complex. Users can see real world with virtual object by overlap computer graphic on the real world. This method provides users with various information about territoriality and openness. As the result of this study it is expected that this technology will help the layout planning of housing complex to become more reasonable in the aspect of design, time and cost.

Developments and changes in digital environment based on computer technologies and internet networks enabled us interactive communication for planning and execution through the freedom of 'connection', 'sharing', and 'conversion'. The subject of this study, interactive commercial, might be the core of success based on creation which stems from communication design, revolution in design and technology, and conversion. Communication in modern economy is not optional, but essential. Furthermore, like evolution process up to Augmented Reality from developments of mobile communication technology, or concept in paradigm change, digital interactive commercial means the core of success, not a part of it. Therefore, in order to achieve success in the global competition structure, mobile communication design, revolution, and creation which produce added value shall be working as a base. In order to reach effective communication process performance of interactive commercial media, this study would like to propose building a media commercial system which is realized by human senses. Using this, standardized methods for interactive commercial which can be used together with augmented reality based on digital technology, and for using digital robot contents are available, along with methodology system of their use. In addition, the ultimate goal of this study aims to discover new factors through reorganization of precedent analysis and adaptation based on academic achievement and practical application. And thus, it wants to contribute to practical use of interactive commercial out of augmented reality-based communication in which technology, marketing, and design are integrated to be used in real sense.
