Until last month, I have been conducted research about golf rules by doing in-depth interviews, video records, and questionnaires. Moreover, then, analyzed all of the research by using open coding as well as axial coding. Also, I made the first prototype which is a VR video, application, and a toy figure about the education of golf etiquette for the junior. Also, I did first user test with two golf instructors. In July, I tried to make the prototype in detail. Also, I focused on user tests as well as revised the prototype. Besides, I founded the importance of VR systems in education by analyzing literature review.

Making prototype
I designed a character which represents the application as well as the main menu. Also, I conducted taking videos in the golf course to make VR videos. Moreover, I tried to revise prototype many times.
First of all, I designed the character to apply in the education of golf etiquette application. I tried to make simple, cute, and friendly. Also, the appearance of monster is the current hot trend among children. This is why the golf character has one big eye. So then, the character name is Golf-E, which means Golf Etiquette.
I drew the wireframe of application. According to the experience of playing golf on the golf course, I divided the main menu into three stages which are teeing ground, fairway, and green. Thus, the three processes of experiences which are teeing ground, fairway, and green are the main menu.
In the second place, after making the character and the wireframe of application, I took VR videos to a driving range to test how it works by using a Samsung 360-degree camera. However, the video files were not available to connect with I-phones because the 360-degree camera could just connect with Samsung smartphones. I asked my friends who works for a design company how can the VR videos show by using I-phones. He gave me to the solution that was uploading the VR video files on YouTube. This media can convert the VR video files that came from a 360-degree camera into the VR video automatically. So, I succeed uploading the VR video on YouTube, and I could see the VR videos on my smartphone. Next step was editing VR videos. However, it was too hard editing VR videos because there were not many programs to make VR contents. I found two programs which are Unity and Premiere CC. The Unity program is making game programs such as a VR shooting game and a car game. Even I tried to cope with this program, it is hard to learn as well as control tools. The last challenge was using Premiere CC. This program is for editing video clips and design the videos, yet the new version of Premiere can handle with VR contents. This is why I learned this program in order to make VR contents by watching YouTube. It was much easier to edit VR videos than Unity.

Thirdly, I had a plan to play golf with my father to take a video for making prototype by using a 360-degree camera. Before took a video, I made a scenario. The scenario consists of the importance of golf rules as well as mistakes of many amateur golfers while playing golf. For example, you cannot touch the golf ball during the game. Even the pace of play was a little bit slow because there were two novices with me, I succeed taking videos while playing golf.

Lastly, after took videos, I edited the video according to three stages which are teeing ground, fairway, and green. Also, I designed application. Also, I did the first user test with two designers with the prototype (the result came out in the User test part). According to the first interview, I revised the application design more familiar with children. Plus, I designed the emotion of character and revised background of the application. There are two reasons why I designed the emotion of the character and revised the background. First of all, teaching emotion is critical for junior to enhance their communication skills and relationship. They have to know how to control the emotion. This is why I designed various kinds of emotion about the character. Lastly, I wanted to show children to the gap between reality and non-reality to show an advantage of the VR system. For example, the Pokémon Go provides people with immersive and interested by showing both reality and non-reality at the same time. If the character that we imagine shows in front of us, it could be more fun and interest. Thus, I combined the character with real pictures. After revised the application, I conducted the second user test with one graphic designer (the result came out in the User test part). When I came back from the user test, I revised the prototype to design more clearly than before. At the same time, I have been conducted to make the character in detail by using Rhino 3D program, KeyShot program. I had to make various kinds of hand gestures as well as the shape of eyes to express emotion such as angry, fun, and happiness. These characters applied to the VR videos. Finally, I made toy figure by using a 3D printer.
In short, I designed the character that name is Golf-E. Also, I drew the wireframe of the education of golf etiquette. Besides, the three stages which are teeing ground, fairway, and green are the main menu. Plus, I took a video to a driving range to test a 360-degree camera. Plus, I took a video on the golf course after undertook to test the 360-degree camera. Moreover, I edited the VR videos by using Premiere CC as well as app design many times.


User test
I conducted user test in two times by asking three designers.
I had first user test on 7th July 2016 with two designers. I showed them to an app design as well as VR videos that I design. One expert told me that the subject is not only very fresh but also the prototype is unique and attractive. However, he asked me to revise the contents design such as the shape of the icon, color, and flow of menu. Besides, he pointed out the flaw that the background in the application looks like the adult not for junior. Another expert thought that also interest in my subject because nowadays the VR system is one of the popular trends. Besides, he told me that the VR could make children more immersive and concentrate on the education environment. However, he also the same opinion of drawbacks with the first expert in terms of the design of app as well as flow.
I had second user test on 17th July 2016 with one graphic designer. His opinion was positive. He said that there are two advantages of the prototype. Firstly, the appearance of the character was not only cute but also familiar with children. Lastly, the prototype was an excellent design for junior as well as appropriate with the main target user. Also, he gave me two recommend improvements. First of all, he wanted to put the factor of interactive in VR system. For instance, children can interact with the character during learning golf etiquette. I tried to put the interactive things in VR contents. However, it was hard to put the factor of interactive things in the VR contents because of time. I already set the time for about 5minutes to learn golf rules. Lastly, he recommended me to change about writing style in the application.
In summary, the three designers gave me to three advantages of the prototype which are the attractive character, appropriacy of the target user, and the fresh of contents. However, they told me to improvements of the prototype which are the design of application and interaction between the prototype and user.

The benefit of using VR systems in education
It is not only hard to teach children to tremendous of information about education but also, there is the limitation to teach them to theory by using print books and videos. For example, if a teacher tries to explain what the solar system is to students by using tennis balls or a science video, students may be hard to understand because those kinds of materials are not real.
There are six benefits of using VR systems in the classroom. First of all, by introducing VR systems in the classroom, students could be better understand because the system provides them with real. In the second place, social interactivity could be improved when students work together through networked mobile devices such as VR goggles and smartphones as well as face-to-face interactions (Birchfield & Megowan-Romanowicz, 2009). Thirdly, supporting customized to various kinds of investigations could be provided to promote individuality (Klopfer, 2008). Virtual reality that brings together learners, virtual objects or information and characters in a real environment have the potential to increase immediacy. Fourth, immersive-media like VR could provide learners with a sense of immersion, which is "the subjective impression that one is participating in a comprehensive, realistic experience" (Dede, 2009, p. 66). Fifth, another significant advantage of using VR systems is safety since unskilled learners can explore potentially dangerous situations without any risk of harm to themselves or damage to expensive equipment. The experience gained by students during the learning process can be a basis for further group discussion in a classroom. Finally, VR systems in education provide students with self-direction and naturalistic learning and increased motivation.
There are three categories of VR education which come from axial coding by analyzing references.
1) Infinite of learning places.
It is important for children to learn by doing. However, nowadays, it is tough to teach them to a large amount of information about education in the classroom. However, students can learn an enormous amount of information anywhere by using VR systems.
2) Reality.
The VR system has the potential to enhance students’ understanding of abstract and invisible concepts or phenomena.
3) Overcome the traditional teaching sessions.
VR system provides students with the real environment as well as interaction. Thus, they cannot only concentrate on the lecture but also, teachers teach students easier than the traditional teaching sessions.

In conclusion, I revised the prototype by conducting user test during this month. Even though there were many problems to make the prototype, I could overcome by doing iteration user test. Moreover, I found three importance categories of VR education which are infinite of learning places, reality, and overcome the traditional teaching sessions. These three types are linked with reality, being there, and presence. Thus, I could found three concepts by analyzing literature review. The three concepts are being there, reality, and presence. I believe that my golf education tool will change the golfers’ behavior more kind and polite by providing them with real.
