Masaki Koshi (~2020.03)

What was your research?

Have you ever worn earplugs or listened to music when you needed to concentrate on your work? It is believed that the reason for this is you can improve work efficiency by blocking auditory noise in the surrounding environment. In my research, I have proposed a method of extending this concept of auditory noise to the visual information in order to improve work efficiency. Specifically, I applied grayscale and blur processing to the surrounding environment, and magnification effects to focus more on the work area.

What are some of the strong points of our laboratory?

There are many good points in our laboratory, but if I had to pick one, I would say that it is easy for people from other fields to join. When I was an undergraduate student, I majored in agriculture, and I was engaged in genetic modification and long-term culture of E. coli bacteria. The teachers are very approachable and the lab is well equipped with advanced facilities. This makes it easy for students with various backgrounds to get together and generate ideas.

Tatsuya Okubo (~2020.03)

What was your research?

I was developing a shopping support system to enable people with visual impairments to shop at a new store by themselves without anybody’s help. As a user walks through the store with a wearable camera, the proposed system automatically creates a map of the store, recognizing what is sold where, as well as predicting the map for the unobserved area. When the system finds the desired product location, it guides the user to the shelf by sound or tactile feedback. To achieve this, I used computer vision technologies such as Visual SLAM and deep learning-based object recognition. Experiments on the prototype system in a virtual environment have confirmed that it could help a user shop at a store without relying on visual information.

What are some of the strong points of our laboratory?

There are many good things about the lab, but personally, it’s the atmosphere and comfort. You can get some equipment necessary for research and high-end PCs are distributed, so you can get exposed to VR and machine learning besides research. I can work on my research at my own pace since I can study at my discretion rather than being forced. Lastly, the teachers are very kind. They don’t coddle you, but gently guide you while beating your butt. They never denied me when I made a suggestion or said something at a meeting, and they thought seriously about it with me, which I really appreciated. It was such a comfortable lab life that I did not want to graduate.

Shido Okubo (~2020.03)

What was your research?

I created a Mirror Visual Feedback (MVF) system and studied the impact of the MVF on users. Five parameters, contrast, brightness, camera angle, facial expression, and posture, were used to manipulate self-image impressions, and the effect of MVF was tested by using an interview task. The results confirmed that although self-evaluation of the participants’ self-esteem decreased, their facial expressions and movements improved when the three parameters of contrast, brightness, and camera angle were manipulated to give a negative impression, their behavior was improved, and their interview ratings by a third person also increased.

What are some of the strong points of our laboratory?

The good thing about the CARE Lab is that it’s an environment where you can do all the research you want to do! Students can take the initiative in research, from coming up with their own research plan to conducting experiments. In addition, all the professors are friendly, and they are always ready to help you out sometimes with jokes, so you can enjoy a safe and fulfilling research life. I hope you will pursue your research to the fullest!

Shingo Okeda (~2019.03)

What was your research?

I studied the transition method between reality and VR. My goal was a “realistic”  VR experience that does not feel fictional. The transition uses an omnidirectional video captured from the user’s point of view. This shows that it is possible to maintain the sense of being in present reality from the user’s viewpoint. This can be achieved with both low cost and high quality. In the experiment, I sought general and effective transition methods. I also worked on better experiment evaluation while collaborating with different professors in interdisciplinary fields.

What are some of the strong points of our laboratory?

I recommend this laboratory because of the comfortable, friendly and cozy atmosphere. The professors are friendly and always available for consultation on all matters. I was able to rely on this, and it greatly increased my research productivity. Additionally, research can be carried out on an individual level. Opportunities such as overseas collaborations and internships are also possible. I was able to do as much research as I wanted! I highly recommend this laboratory to students who are considering to join.

Shuhei Terada (~2019.03)

What was your research?

My research was about the development of a system to prevent overeating. It uses visual and tactile feedback. The aim was to give the illusion of satiety and reduce the amount of food consumed. This was done by using haptic and visual display devices to exaggerate three physical feedback points that are commonly available during meal consumption; abdominal swelling, abdominal skin tension, and abdominal weight. In the end, I was able to reduce the amount of food consumption by around 7% using the proposed system.

What are some of the strong points of this laboratory?

The good thing about this laboratory is that it is possible to greatly expand your range of knowledge because the members work in different research fields. In addition, equipment costing hundreds of thousands of yen, which can’t normally be obtained by ordinary students, is all over the laboratory. You can also study abroad or attend academic conferences related to your own research, with almost full financial support. With an environment this rich in human resources, equipment, opportunities, and assets, please challenge yourself and the very potential of science!

Frédéric Huynh (2018.09~2019.03, Intern)

What was your research?

Hi ! I’m Frédéric Huynh, former international intern in CARE Lab. I was an embedded system student back in France and I got the chance in the lab to explore the possibilities brought by the Microsoft AR headset : Hololens. My work was to come up with an AR user interface that would label every reality objects in the user’s field of view. The application of the research could be for factory work, each piece would have its name, description, id and tutorial for example.

What are some of the strong points of this laboratory?

I enjoyed my 6 months stay in Japan. One of the big reasons was because the lab is like a big family. We help each other, have fun together. They are very welcoming so don’t hesitate to go and talk to them about anything. Japan has a unique vibe that you can only experience yourself when you are there, so go ahead and come !

Etienne Juif (2018.06~2018.09, Intern)

What was your research?

Hello, my name is Etienne Juif and I was an intern at CARELab in 2018. I was coming from a school focused on combining Art and Sciences. I joined the lab because I wanted to try to add the Virtual Reality to this formula and to create some experiences around it! I created with Unity a painting application in Mixed Reality allowing you to draw, create shapes and cut objects around yourself.

What are some of the strong points of this laboratory?

It’s an awesome place. I was afraid to leave France but CARELab’s members were really helpful and made this adventure really easy! If you want to experiment things in VR, you will have everything you need to work and people will listen to you and try to find solution to let you achieve your projects. Also, it’s really fun to be able to talk with people in the Laboratory, you will meet a lot of diverse people and it’s amazing to exchange with them. One of my best memories was when someone tested my application, created an obstacle course in the Lab and tried it! You can trust them, they are really good!

Nguyen Hien Minh (2018.05~2018.08, Intern)

What was your research?

Hello, my name is Minh, and I was an intern at CARE Lab along with my friend Moha, in 2018. We wanted to be able to convert in real-time a photo taken during the night to one that seemed to have been taken during the day. The project consisted in programming a robot to gather a dataset of a same scene during the day and the night, and then train a Pix2pix neural network using this dataset. You can find a preview/demo of our project here:

What are some of the strong points of this laboratory?

I had a wonderful time during my three months in the lab. My recommendation for future students: the lab is an awesome and cozy place, the teachers are friendly and helpful and the students are very nice! Go talk to people, go visit all the places you want and please enjoy your stay in Japan!

Takuya Mizoguchi (~2018.03)

What was your research?

The master’s research theme was the “Proposal of top-down segmentation method for printed dot-matrix characters.” An example of dot-matrix characters includes characters printed on PET bottles to indicate the expiration date of a product. The research aim was the feature extraction of single characters from an image capturing printed dot-matrix characters. If you’re interested, please take a look at my master’s thesis.

What are some of the strong points of this laboratory?

In a nutshell, you can do a variety of things in this laboratory if you’re motivated. Since the CARE lab was established just a few years ago, I think it is relatively easy to propose your own idea and get approved as your research theme. Also, being able to receive accurate feedback on your research from faculty members with interdisciplinary knowledge was very attractive. So, for those willing to put in the effort, including undergraduate students interested in VR/AR research, please join and enliven the CARE lab!

Humberto Trujillo Perez (2017.10~2017.12, Intern)

What was your research?

My name is Humberto Trujillo, in 2017 I was a master’s degree student in Mexico when I got the opportunity to do an internship at NAIST’s CARE Lab. My research was initially focused on the development of a low cost wireless real-time motion capture system based on inertial measurement unit sensors and its integration in VR/AR environments. During my internship, I got the chance to collaborate with other fellow research students and worked on a motion pattern recognition and classification model that would later be used to classify different types of racket movements in the sport of Badminton with high accuracy.

What are some of the strong points of this laboratory?

As a foreign student, I was surprised by how welcoming and friendly both teachers and students are. Teachers are very experienced and knowledgeable in many different areas, and always willing to offer their help. The students are nice and really easy to establish good communication with. I enjoyed staying late in the lab playing video games or going out for dinner with them. I really liked the weekly meeting format where all students present the progress on their research, it is the perfect place to learn something new and receive constructive feedback about your work.
