ARgent: Web Tabanlı Dinamik İçerik Destekli Artırılmış Gerçeklik Geliştirme Altyapısı

Öz

Günümüzün dünyasında insanlar interaktif teknolojilere daha fazla ilgi duyuyor. İnteraktif teknolojilerin en yenilikçi örneklerinden biri olan artırılmış Artırılmış gerçeklik (AG), her ne kadar işe yarasa da, AG uygulamaları geliştirmek programlama ve oyun geliştirme araçları hakkında uzun süren eğitimler sonucu kazanılan bilgi ve tecrübeler gerektiriyor. Diğer yandan tasarım ve içerik oluşturma konusunda yetenekli insanlar, AG uygulaması geliştirmekten ve yönetmekten mahrum kalabiliyor. Bu makalede ARgent, Unity’de geliştirilen bir AR geliştirme aracı tanıtılacaktır. Bu altyapı iş akışının tamamını kapsayan bir yol haritası temin eder ve sunucu, web arayüzü ve mobil uygulama gibi üç ayrı cephede hizmet verir. Sunucu objelerin paketlenmesi ve optimizasyonu, veritabanı yönetimi ve verinin web arayüzü ve mobil arayüze sağlanması gibi görevleri üstlenir. Web arayüzü kullanımı kolay ve herkes tarafından erişilebilir olması neticesiyle bir içerik yönetim sistemi olarak görev görür. Mobil uygulama ise son kullanıcı tarafından kullanılacak uygulamadır. ARgent sadece kullanıcı arayüzünü (GUI) kullanarak ve hiçbir programla yapmaya gerek kalmadan uygulamalar geliştirilmesini sağlayacaktır. Kullanıcılara alışık oldukları bir deneyim sunmak amacıyla, işlemler halihazırda varolan diğer araçlara benzer olacaktır. Unity’de görsellerin dinamik olarak içeri aktarılması sebebiyle ortaya çıkan performans problemleri, ARgent’in sunduğu ve yenilikçi bir yöntem olan “asset bundling” yöntemi ile çözülmüştür. Son olarak, altyapı bir Javascript motoru barındırır ve böylece kullanıcılar kendi betiklerini entegre ederek isteğe göre kullanıcı arayüzü ve nesne davranışı tanılmayabilir.

ARgent: A Web Based Augmented Reality Framework for Dynamic Content Generation

Abstract

In the modern world, people are more and more interested in interactive technologies. Despite the usefulness of augmented reality, which is a novel addition to those interactive technologies, its development still requires knowledge and experience with programming and game development tools gained by long-term education and training. People experienced in design and content creation can be deprived of the ability to create and maintain AR applications. In this paper, ARgent, an AR authoring tool developed in Unity will be introduced. This framework will supply the whole workflow pipeline which involves modules targeting the tree fronts: the server, the web interface and mobile application. The server will be responsible for packaging and optimizing objects, doing database processes and serving the data to the web interface and mobile application. The web interface will be used for content management as web applications are easy to use and easily accessible. The mobile application is the application that will be used by the end user. ARgent will provide a way to create applications entirely in a Graphical User Interface (GUI) without needing to write any line of code. The User eXperience (UX) will be familiar to the existing tools to keep users engaged with the development process. ARgent provides a way to import dynamic assets, create animations and optionally create scripts for custom behavior, all within its web interface. ARgent features “asset bundling” method, a novel way to optimize and load dynamic assets, which eliminates performance issues arising from using dynamic assets in applications built with Unity. Finally, a JavaScript engine is added to the framework so that users can write their own scripts enabling them to create custom user interfaces and to assign behaviors to them.
