This chapter presents a series of new augmented reality user interaction techniques to support the capture and creation of 3D geometry of large outdoor structures. Named construction at a distance, these techniques are based on the action at a distance concepts employed by other virtual environments researchers. These techniques address the problem of AR systems traditionally being consumers of information, rather than being used to create new content. By using information about the user’s physical presence along with hand and head gestures, AR systems can be used to capture and create the geometry of objects that are orders of magnitude larger than the user, with no prior information or assistance. While existing scanning techniques can only be used to capture existing physical objects, construction at a distance also allows the creation of new models that exist only in the mind of the user. Using a single AR interface, users can enter geometry and verify its accuracy in real-time. Construction at a distance is a collection of 3D modelling techniques based on the concept of AR working planes, landmark alignment, constructive solid geometry operations, and iterative refinement to form complex shapes. This chapter presents a number of different construction at a distance techniques, and are demonstrated with examples of real objects that have been modelled in the physical world.

As If

Augmented reality is defined as the technology in which virtual objects are blended with the real world and also interact with each other. Although augmented reality applications are used in many areas, the most important of these areas is the field of education. AR technology allows the combination of real objects and virtual information in order to increase students’ interaction with physical environments and facilitate their learning. Developing technology enables students to learn complex topics in a fun and easy way through virtual reality devices. Students interact with objects in the virtual environment and can learn more about it. For example; by organizing digital tours to a museum or zoo in a completely different country, lessons can be taught in the company of a teacher as if they were there at that moment. In the light of all these, this study is a compilation study. In this context, augmented reality technologies were introduced and attention was drawn to their use in different fields of education with their examples. As a suggestion at the end of the study, it was emphasized that the prepared sections should be carefully read by the educators and put into practice in their lessons. In addition it was also pointed out that it should be preferred in order to communicate effectively with students by interacting in real time, especially during the pandemic process.

Main Operating

Augmented reality (AR) is the integration of digital information with the user’s environment in real time. AR software use in many different ways and for the needs of cartography too. This technology may be useful for the development of navigational mobile applications and actions with static (paper) maps. There are two main operating modalities for implementation of augmented reality in applications: by markers and by the positioning of customer and surrounding objects (by azimuths determination between customer’s device and real objects). The first way is applied for static maps when another way is applied for navigational mobile applications. Augmented reality provides at least six opportunities, which create better options for working with design and content of maps for cartographers. This technology also provides the new experience in the work on maps for customers. The advantages of using augmented reality in cartography are the partial equation of static maps to geographical information systems, adaptability of cartographic images to the needs of users, improving the quality of design and content possibilities of maps and making actions with maps more attractive for customers. However, this technology is not without disadvantages, which connected with the development of AR-applications and requirements to smartphones. In addition, this article reveals aspects of the creation of augmented maps in cartographic companies.

Commercial Field

In recent years, Augmented Reality has become a very popular topic, both as a research and commercial field. This trend has originated with the use of mobile devices as computational core and display. The appearance of virtual objects and their interaction with the real world is a key element in the success of an Augmented Reality software. A common issue in this type of software is the visual inconsistency between the virtual and real objects due to wrong illumination. Although illumination is a common research topic in Computer Graphics, few studies have been made about real time estimation of illumination direction. In this work we present a low-cost approach to detect the direction of the environment illumination, allowing the illumination of virtual objects according to the real light of the ambient, improving the integration of the scene. Our solution is open-source, based on Arduino hardware and the presented system was developed on Android.

Reality Increasing or often also called AR (Augmented Reality) in English, is a technology that can add two-dimensional or three-dimensional illusions of objects together into a 3D into the real world then project illusion objects into real time. Unlike the illusion of reality where in the real world is completely replaced, reality only adds to or completes reality. Augmented Reality unites real objects and illusions into real circles, works interactively in real time and found integration between objects in 3D and good integration requires effective investigation. Web AR provides Web-based access using Augmented Reality through a web browser using a combination of technologies including WebRTC, WebGL, WebVR, and Modern APLs sensors. Catalogs are publicity tools used by companies as a way to promote their products and services. Examples of companies that use catalogs are Furniture stores that promote products. Here it will be visualized into 3D until it looks more clear and attractive to consumers. So, based on the description above, the author takes the title "Implementation of Augmented Reality with Marker Method as Media Catalog in AR-Based Furniture Stores.

Output Information

Getting information in real time at specific times and locations is especially needed when users have high mobility. But often users are not familiar with the area, so difficulty in finding locations and information. The development of technology for location based services and augmented reality makes it easy to get information from available resources in locations using mobile devices equipped with GPS devices. The research aims to combine hotel location based services and augmented reality in android-based mobile device by manipulating virtual objects into real objects through the camera as input and mobile phone display as output.The integration of hotel location based services and augmented reality is useful for hotel users to be able to search hotel information by directing the camera mobile device in the direction of specific targets to be retrieved information. The output of the system is provided in real time on the mobile device display for the user. Output information provided in the direction of location of the hotel object and information about the object of the hotel.

This work presents an approach to render appropriate shadows with Image Based Lighting in Augmented Reality applications. To approximate the result of environment lighting and shadowing, the system uses a dome of shadow casting light sources. The color of each shadow is determined by the area of the environment behind the casting light source. As a result it is possible that changes in the lighting conditions immidiately affect the shadow casting of virtual objects on real objects
