Augmented Reality Project of

Solar System

1.     Introduction

The app presents the solar system to present the solar system to the students with a global view, the purpose is to enable the students to be interested in the galaxy and improve the students' concentration in class.

2.     Description of the application

This program constructs the solar system, a system of celestial bodies centered on the sun and bound together by the sun's gravity, including the sun, planets and their moons, dwarf planets, asteroids, comets, and interplanetary matter.

The app allows students to recognize eight different planets and explore them freely through Augmented reality (AR). AR can present various forms of information, such as 3D, 2D, text, video, and animation, etc., through which users can interact with events and information naturally(Erdem 2017). A variety of information interaction methods help to attract students' attention and improve students' interest in learning. AR can combine real scenes and virtual worlds, and can meet the needs of human interaction and control at the same time(Adhani & Rambli 2012). This will better show students what they need to learn in the classroom.

In the traditional education model, teachers can only teach by reading texts and pictures. In this case, unless the students themselves are interested in knowledge, it is difficult to mobilize the students' enthusiasm for learning. Or students are only attracted by bright pictures and neglect to learn knowledge. AR technology has a profound impact on education and teaching, as it can combine the real and virtual worlds. Let students have the opportunity to interact with teaching materials, enrich children's horizons, and improve children's learning enthusiasm. Most children of all ages enjoy astronomy and studying galaxies in the solar system. Therefore, the program will start with the solar system, display the solar system with 3D models, and dynamic effects, and make a solar system education project by adding sound and other means.

3.     Interaction Design

After scanning the picture with the device, the user will see the sun, earth, moon and other planets. They revolve around the sun at the same time as they rotate. Students can see how fast different planets rotate and revolve, and how far away they are from the sun.

In addition, the user can click slow, and the rotation and revolution speed of the planet will slow down, reaching a state that seems to be stationary. This allows students to observe the individual planets more closely. In this interaction design, each planet is not in a suspended state at the beginning, and the rotation of the object is controlled by the button, which is considered to be able to see the rotation of all the planets at the beginning. It is more beneficial to students It's shocking and instantly grabs the student's attention. The logic behind this interaction design is completely different, from static to rotating, to turning to seemingly static. The difference behind this determines whether it can make the classroom livelier and more interesting. The slow-to-seemingly static design allows students to further observe the planets while having a sense of entering a space environment, keeping the solar system alive, rather than completely stopping like lifeless objects.

Secondly, the music button will play music that makes people feel like they are in an empty and peaceful world. This is to enhance the user's immersive experience. Especially when users observe the rotating planets, they can let them forget themselves and focus on the exploration of the solar system.

4.     Technical development

In this project, AR technology is mainly used for development and Vuforia is used to realize the scene. All functions are implemented using C#. Each planet uses a sphere, and uses reasonable textures to show the different planets.

Over all, all the interactions of the project are enough to run normally, the interaction design is suitable for educational and teaching application scenarios and easy to use.
