In this paper, we present the software architecture of a complete mobile tourist guide for cultural heritage sites located in the old town of Chania, Crete, Greece. This includes gamified components that motivate the user to traverse the suggested interest points, as well as technically challenging outdoors augmented reality (AR) visualization features. The main focus of the AR feature is to superimpose 3D models of historical buildings in their past state onto the real world, while users walk around the Venetian part of Chania’s city, exploring historical information in the form of text and images. We examined and tested registration and tracking mechanisms based on commercial AR frameworks in the challenging outdoor, sunny environment of a Mediterranean town, addressing relevant technical challenges. Upon visiting one of three significant monuments, a 3D model displaying the monument in its past state is visualized onto the mobile phone’s screen at the exact location of the real-world monument, while the user is exploring the area. A location-based experience was designed and integrated into the application, enveloping the 3D model with real-world information at the same time. The users are urged to explore interest areas and unlock historical information, while earning points following a gamified experience. By combining AR technologies with location-aware and gamified elements, we aim to promote the technologically enhanced public appreciation of cultural heritage sites and showcase the cultural depth of the city of Chania.

Abstract. This paper presents an algorithm developed to solve a problem during the development of a system to estimate de 3D model of buildings roofs and its incorporation into a BIM. The chosen schema for the BIM is gbXML and one of its condition is that the vertexes that describe the model surfaces must be counterclockwise ordered. Due to the variability in the orientation of the analysed surfaces, the algorithm must be able to work with any surface regardless its orientation. Also, this paper includes the testing of the algorithm. This test is based on the application of the developed algorithm among three different real-world scenarios.

Augmented Reality (AR) is a variation of the virtual environment or more often calledasAR technology users that can see the real world, with virtual objects added to the real world. So, users see virtual objects and real objects are in the sum place. Augmented reality requires streaming video with a camera that is used as a sowce of image input, then tracking and detecting markers. After the W is detected 30 model will appear of an item. This 3D model was mated mite software for 3D design, jbr example 3DS Max. Blender and others In this ancient animal Ieaming media using pattern recognition that can be interment! as taking raw data and based on data classification Then it can take the mutation problem how to design 30 objects with the Blender application to introduce d anc‘ient animals. purpose of this m is to build ancient animal leaning media in real time by using augmented reality technology.

Augmented Reality is the presentation of objects superimposed on the real world view of the environment. It is an innovative technology that allows multidimensional viewing and understanding of concepts. This paper aims to use this concept of Augmented Reality in the field of Education to create an application that generates 3D models of the images embedded in textual materials using the software Unity and Vuforia. The application uses a smartphone’s camera to scan the embedded image of a textbook, e-book or photocopy and generates a 3D working model with live animations as well as on-click functionalities to view various movements of the model by providing user interaction. This application aims to provide an active learning experience to students.

Currently, virtual technology is applied to everyday life. AR (Augmented Reality) has widely become a challenger technology that brings virtual 3D images into the real world through a camera. Augmented Reality is a technology that brings virtual images that is a 3D model simulated into the real world through cameras and processing that brings objects to overlap into one image and AR can help people to understand the content easily. Hence, in increasing the efficiency of services and publicizing various information, this paper presents the smart navigation system using augmented reality based on a smartphone in the case study of Benjakitti Park, Thailand. The application can navigate users to the POI destination and the system based on mobile devices is composed of two parts: the navigation application and the bone collector game. This project produced user satisfaction at a good level and the proposed application was able to support the significant information for navigation in aspects of performance, usability, and effectiveness.

Craniofacial superimposition is a forensic process that aims to identify a missing person by overlaying a photograph and a model of the skull. This process is usually carried out manually by forensic anthropologists, thus being very time consuming and presenting several difficulties when trying to find a good fit between the 3D model of the skull and the 2D photo of the face. This contribution aims to provide both a detailed description of the problem and the proposal of two different designs of a multimodal (clearing) genetic algorithm to tackle it. The new proposals will be tested on superimpositions for different real-world identification cases from the Physical Anthropology lab at the University of Granada in Spain, including positive and negative cases, taking the manual and the basic genetic algorithm solutions as baselines for their quality.

Abstract. This paper discusses the capabilities of cadastre augmented reality (AR) and three-dimensional (3D) visualization in enhancing the stratified property visibility and information of the current strata plan in Malaysia. Currently, 2D information representation from the 2D+1D cadastre system is seen to be insufficient in serving real land management of the 3D aspect and property. Hence, toward a better digital 3D strata/property registration and land administration system in Malaysia, this study has explored the process in utilizing AR and 3D model to the current strata plan to enhance digital strata information contents and enabling the virtual strata plan presentation. The software used to develop the AR application smartphone was Unity3D software while Autodesk Revit applied to develop the 3D model and preparation of strata information. The interesting findings has been shown in this study. First result showed 3D models and strata parcel’s attribute that has been developed for AR digital content preparation. Secondly, this 3D-AR processes can continuously gather of user’s ambient information, conduct real-world recognition, and obtain real-world perception through smartphone device. Lastly, with utilization of AR technology in strata, it provides a more information to the strata plan without needing to change the current format of strata plan as the information are being displayed virtually onto the reality. With the integration of augmented reality and 3D visualization, the documentation of stratified properties in strata plan is potential to be enhanced from 2D planimetric to 3D representation. overlaid 3D model of the stratified property and standard strata information virtually on the present strata plan which has created an enhanced reality. This can allow the information to be viewed by more stakeholders with less restriction by using smartphone device.
