Abstract

Augmented Reality (AR) is a technology which render visual information such as three-dimensional (3-D) virtual objects and allow users to interact with virtual and real object at the same time. This technology can help student to learn intuitively and interactively through simulation which is equipped with AR. This paper discusses the physic simulation such as force, gravity, friction, spring, gears and chain through AR. The system that we built is deployed on mobile platform specifically Android based devices and based on marker-less AR. Instead of a black-and-white square marker, we use image corresponding the context to trigger and visualize the simulation. By simply touch the correspondent image, student can interact and alter the course of the physic simulation.

Abstract

Augmented Reality (AR) is a research area that allow to overlay multimedia contents such as text and visual information onto real world through camera views. AR can be used to as an educational assistance to help student acquire a deep conceptual understanding and spatial intuition. The course material can be enriched by viewing multimedia content, as well as in tabletop AR environment. We present this paper an AR system for teaching chemical problem solving especialy chemical bonds to highschool students.  Our system is built based on inexpensive webcams and open-source library. Chemical bonds are visualize through marker. By combine different markers, student can get different result and visualization.  A survey was conducted after experience the AR chemical bonds, show great acceptance of system and visualization.

Abstract

We present an 3D Modelling  object for  batik Gallery  in virtual reality with textured material photo,  Lighting effect  and primitive mess with Normal Mapping Metthod. Normal Mapping is one of many method  to  give  depht  Impression texture and detail for object without  many   polycount, so we can get  efficiency of the computer work without loss of detail desired.  in this research  we try to explain  several techniques in making batik Gallery design textures with  modeling 3D,  The methods include stage Normal Mapping, Environment maps, bump maps, and shadow maps. The next proscess we can use Directional Light and Point Light for each object to get the  impression of depth and real dimension for each  texture.  The result of this research is  to improve  the modern batik consept and patterns with immersive  3D Room  in Virtual reality

Abstract

Kamera virtual merupakan bagian utama pada sebuah permainan yang mampu menampilkan obyek dan peristiwa dalam lingkungan virtual. Permasalahannya adalahketika sedang dimainkan, kamera tidak mampu menampilkan peristiwa penting yang terjadi didalamnya. Untuk itu, perlu sinkronisasi antara teknik pengaturan kamera dengan peristiwa penting tersebut. Dalam penelitian ini, untuk menciptakan sinkronisasi antara teknik pengaturan kamera virtual dengan peristiwa penting yang terjadi dalam permainan dilakukan menggunakan Behavior Tree. Penelitian dilakukan pada permainan Turn-Based Strategy (TBS) yang memiliki sistem autonomous leveling dinamis, yaitu sistem peningkatan level permainan tidak selalu sama dari level satu ke level berikutnya.Kategori peristiwa penting dalam permainan TBS ini antara lain peristiwa saat permainan dimulai, pemain mendapat giliran, pemain membidik lawan, pemain menyerang, terjadi benturan dan nilai health point (HP) dalam kondisi habis. Dan teknik pengaturan kamera tersebut antara lain teknik moving, zooming, focusing, chasing, dan shaking. Dari hasil percobaan melalui kuisioner yang telah didistribusikan, responden menyatakan bahwa teknik pengaturan kamera virtual dengan peristiwa saat permainan dimulai adalah 100% sinkron, saat pemain mendapat giliran 96% sinkron, saat pemain membidik lawan 83% sinkron, saat pemain menyerang 86% sinkron, saat terjadi benturan antar pemain 100% sinkron, dan saat nilai HP pemain habis 93% menyatakan sinkron.
