In the beginning, many tools and methods were recommended to implement the proposed solution, and we concluded that “Augmented Reality” and “Virtual Reality” techniques are the best in delivering the solution. “Virtual Reality” has been used to simulate the problem, focus on it, and make notes on it, and it allows interaction with elements by tracking and analyzing the movement of the body where these technologies are currently being used and applied in many fields, especially in education and application. The use of “AR” contributes greatly to the delivery of information and interaction with the (3D) elements that appear in the reality accurately and dazzlingly from anywhere and at any time, especially since the project requires high-resolution and clear illustrations. “Augmented Reality” provides the opportunity for continuous movement and interaction with models, which enhances the delivery of information and the curriculum in a smoother manner. Through "AR”, user applies his creative skills and the principles of immersed learning, as he/she relies on his information gained from his live experience through (Visualooh). “Unity 3D” was used to implement all these ideas as it greatly supports these technologies, and it can be controlled greatly and effectively as we can make the solution with the highest scientific accuracy and apply it professionally as well as our experience in working with them.

The solution timeline has three phases and the first phase the player learns about the life cycle of the star from the beginning to the end by showing him/s her the following stages of a star.

1. First, the player sees the sun as an example for a main sequence star and the beginning of its creation which takes place because of the fusion converting hydrogen into helium which lasts for about 5 billion years

2. Then the sun changes its color into blue which shows that the hotter star is the brighter star in which its color is blue

3. The star is getting giant and super giant above the main sequence which represents the star when it begins to die as it expands and becomes less bright due to depleting their hydrogen supply

4. After expanding the star becomes either planetary nebula or super nova

5. At it ends as white dwarfs, neutron stars or black holes

After learning about the life cycle of the star in the first phase now the player will know more about the stellar variability and the different properties in the stars which affects on their brightness and color and this phase is consisted of seven real stars data, how do they look, and their masses and radius compared to sun. these stars are:

1. Rigel which its spectral type is B, its absence is 0.1% and its temperature is 20000 K

2. Sirius which its spectral type is A, its absence is 0.7 % and its temperature is 8500 K

3. Procyon which its spectral type is F, its absence is 2% and its temperature is 6500 K

4. Sun which its spectral type is G, its absence is 3.5 % and its temperature is 5700 K

5. Lacerta which its spectral type is O, its absence is 0.00001 % and its temperature is 40000 K

6. Arcturus which its spectral type is K, its absence is 8 % and its temperature is 4500 K

7. Betelgeuse which its spectral type is M ,its absence is 80 % and its temperature is 3200 K

The player will be able to zoom into any star he wants from them by keeping looking to it which makes the star comes nearer and its data written under it.

These were the first two phases which depends on the VR but now after learning about all of that the player can customize his own personal star by changing its properties like temperature in which there is a slider which the player can use to customize the temperature of the star and so he/she can see the relation between spectral type of a star and its temperature through seeing the star changing its properties. Also, the player will be able to have a tour in the virtual space lab to see some 3D NASA models like International Space Station (ISS), 3D space rocket and Apollo’s capsule model. 

To develop our solution there were a lot of steps in different fields. Firstly, the design document was made which has the detailed information and points in the game, its concepts and scenes. Then, a Unity project was created and imported the google VR SDK in it as well also importing the 3D assets that we need. The next step was creating the 3d model of the stars based on the details in the design requirement and putting the stars in their real positions and make them with their actual scales, making the VFX and the camera movement, putting the voice over in VFX and then collecting all of these.

how is The AR Done:

1. Creating the unity project.

2. adding the Google ARCore SDK to the project.

3. adding the 3D OBJs to the Scene and starting the level designing process

4. making the slider and linking the material’s color with temp.

5. linking the Object Placement C# Script with the Lab prefab.

 6. testing process and applying.

1- NASA : https://science.nasa.gov/astrophysics/focus-areas/how-do-stars-form-and-evolve , this helped us in understanding more about the stars and their types as well as their life cycle in which those information helped us to introduce scientifically approved information to the user through our project in the Virtual Reality: Phase 1.

2- European Space Agency (ESA) : https://www.esa.int/kids/en/learn/Our_Universe/Stars_and_galaxies/Star_birth , this helped us in understanding the star birth concept but especially to be introduced and explained to kids as from our target audience is the kids and this helped us in Virtual Reality: Phase 1.

3- European Space Agency (ESA) : https://www.esa.int/kids/en/learn/Our_Universe/Stars_and_galaxies/Star_death , this helped us in understanding the star death concept but especially to be introduced and explained to kids as from our target audience is the kids and this helped us in Virtual Reality: Phase 1.

It was a very interesting and useful two days, as we worked on developing the project with the help of the mentors who contributed to developing the project to make it better. We had the pleasure of meeting some famous people, speaking with them and giving us their opinion on our project. We knew a lot of friendly participants and it was our pleasure helping each other. The hackathon was interactive, where we let other participants try the solution and say their opinions. We chose this challenge to solve it because we thought we could put a creative solution to the challenge using new technologies which are virtual reality and augmented and it was as we explained in the “Detailed Project Description section”. Finally, we would like to thank NASA space apps and organizers of this day as well as the “American University in Cairo”, I would also like to thank the mentors and everyone who made these days wonderful.
