Pengembangan Aplikasi Peta Pariwisata Digital Menggunakan Metode Markerless Di Kota Palembang

Based on the results of data obtained from the Palembang city tourism office, activities providing information about tourism are not running optimally in reaching prospective domestic and foreign tourists because activities for conveying information about the attractiveness of tourist attractions through brochures, newspapers, and other print media, as well as events being held, are still ongoing. is temporary; in other words, the delivery of information has not become a routine activity by the Palembang City Culture and Tourism Office. Apart from that, the lack of information related to tourist attractions in Palembang can make it difficult for tourists to determine destinations and travel plans because descriptions of areas or tourist attractions, such as visualization of places and distances between one location and another, are unavailable. Therefore, tourists waste time looking for tourist attractions to visit. This research aims to develop a Digital Tourism Map application in Palembang City which is presented with Augmented Reality in the form of 3D Objects using the Markerless Method so that it can make it easier for local and outside tourists in the Palembang City Area to get to know the tourist attractions in Palembang City. One method currently being developed is the Markerless method; with this method, users no longer need to print a marker to display digital elements

Edukasi Pengenalan Huruf Hijaiyah dengan Memanfaatkan Teknologi Augmented Reality

Augmented Reality (AR) technology provides opportunities for science and engineering. AR also has great opportunities in the world of education, which is to provide and display additional information in the form of 3D objects, video, sound, and text on an object. Smartphone software developers have developed Augmented reality technology that was previously developed on PC devices where this technology utilizes the existing camera on a smartphone. With this situation, AR technology has the opportunity to be used in the development of a media for recognizing hijaiyah letters, so that children will be happier learning because of its attractive appearance and teachers or parents can more easily teach lessons to their children. The way to use it is as follows: first, the user puts a registered and printed marker, second, the smartphone camera identifies (tracking) the marker. If the marker is invalid, the user repeats the identification process. If the marker is valid and identified, the marker will display the hijaiyah letter object in three-dimensional form. Third, users can understand the shape and pronunciation of hijaiyah letters by touching the virtual button on the marker

The benefits of using this application are to make it easier for midwifery academics in the learning process for parturition(childbirth).

A stratified process for the perception of objects: From optical transformations to 3D relief structure to 3D similarity structure to slant or aspect ratio

Previously, we developed a stratified process for slant perception. First, optical transformations in structure-from-motion (SFM) and stereo were used to derive 3D relief structure (where depth scaling remains arbitrary). Second, with sufficient continuous perspective change (≥45°), a bootstrap process derived 3D similarity structure. Third, the perceived slant was derived. As predicted by theoretical work on SFM, small visual angle (<5°) viewing requires non-coplanar points. Slanted surfaces with small 3D cuboids or tetrahedrons yielded accurate judgment while planar surfaces did not. Normally, object perception entails non-coplanar points. Now, we apply the stratified process to object perception where, after deriving similarity structure, alternative metric properties of the object can be derived (e.g. slant of the top surface or width-to-depth aspect ratio). First, we tested slant judgments of the smooth planar tops of three different polyhedral objects. We tested rectangular, hexagonal, and asymmetric pentagonal surfaces, finding that symmetry was required to determine the direction of slant (AP&P, 2019, https://doi.org/10.3758/s13414-019-01859-5). Our current results replicated the previous findings. Second, we tested judgments of aspect ratios, finding accurate performance only for symmetric objects. Results from this study suggest that, first, trackable non-coplanar points can be attained in the form of 3D objects. Second, symmetry is necessary to constrain slant and aspect ratio perception. Finally, deriving 3D similarity structure precedes estimating object properties, such as slant or aspect ratio. Together, evidence presented here supports the stratified bootstrap process for 3D object perception. Statement of significancePlanning interactions with objects in the surrounding environment entails the perception of 3D shape and slant. Studying ways through which 3D metric shape and slant can be perceived accurately by moving observers not only sheds light on how the visual system works, but also provides understanding that can be applied to other fields, like machine vision or remote sensing. The current study is a logical extension of previous studies by the same authors and explores the roles of large continuous perspective changes, relief structure, and symmetry in a stratified process for object perception.

Augmented Reality (AR) based application to introduce animals for children

The development of technology today is very helpful in the multimedia-based learning process. Children will be more interested in learning if the application can be installed on a Smartphone, because children enjoy playing Smartphones. In teaching children to recognize animals, teachers at school use pictures. With the presence of multimedia based on Augmented Reality (AR), it is helpful for displaying images of animals in 3-dimensional form so it is more interesting. Applications created can help children to classify, explain about animals through information about sounds, habitat, breeding about animals in the form of 3D objects. In making Augmented Reality Animal Recognition, the researcher adopted the SDLC (System Development Life Cycle) method. At the trial stage, the Alpha version of the application was carried out to determine the quality, shortcomings and smoothness of the application that had been made. Application test results could run well. Therefore, through this application, children are more interested in getting to know animals so that it provides a learning experience and is easily accessible on smart phones.

Mobile Art Application (MATA) as a media for handling cases of aggression in children

The difficulty experienced by most children is ability in terms of emotional control. So that they often have difficulty in conveying the things they want. And the culmination is an attitude of aggression in children. The solution to this problem is psychological therapy. Many therapeutic models are commonly used in the field of psychology, one of which is art therapy. The method used in this study is the experimental psychology method. The problem solving strategy in this study uses a technological approach. Art therapy is made on the basis of mobile technology, so that its application becomes more interesting and interactive.

The results of the scratches will appear in the form of 3D objects using augmented reality technology. The creation of applications in the form of real time coloring in augmented reality objects, is expected to be a medium for channeling emotions for children. So that it can be used as a therapeutic medium that can reduce the level of aggression in children.

A VISION-BASED LOCATION POSITIONING SYSTEM VIA AUGMENTED REALITY: AN APPLICATION IN HUMANOID ROBOT NAVIGATION

In this paper, we present a vision-based localization system using mobile augmented reality (MAR) and mobile audio augmented reality (MAAR) techniques, applicable to both humans and humanoid robots navigation in indoor environments. In the first stage, we propose a system that recognizes the location of a user from the image sequence of an indoor environment using its onboard camera. The location information is added to the user's view in the form of 3D objects and audio sounds with location information and navigation instruction content via augmented reality (AR). The location is recognized by using the prior knowledge about the layout of the environment and the location of the AR markers. The image sequence can be obtained using a smart phone's camera and the marker detection, 3D object placement and audio augmentation will be performed by the phone's operating processor and graphical/audio modules. Using this system will majorly reduce the hardware complexity of such navigation systems, as it replaces a system consisting of a mobile PC, wireless camera, head-mounted displays (HMD) and a remote PC with a smart phone with camera. In the second stage, the same algorithm is employed as a novel vision-based autonomous humanoid robot localization and navigation approach. The proposed technique is implemented on a humanoid robot NAO and improves the robot's navigation and localization performance previously done using an extended Kalman filter (EKF) by presenting location-based information to the robot through different AR markers placed in the robot environment.
