NHK Interview at NIFS in Kanoya

Hello everyone.

I am D2 Oral Kaplan.

During the last month, I have been to NIFS in Kanoya for a totally different purpose; to take part in an interview of NHK. Main topic was the system that we are trying to develop for supporting elderly and their training activities.

It was a quite fascinating experience for me, and I hope I can make the system better with each passing day. Who knows; thanks to all these efforts, one day I might even become a widely known individual in Japan ! 🙂

Below are the photos of Prof. Yasuhide Yoshitake from NIFS in Kanoya being interviewed and Prof. Takafumi Taketomi enjoying the game with him. I also managed to get some screen time during out short meeting! 🙂

2017 graduation ceremony

Hello, I am M1 student Mizuki Ando.

The graduation ceremony was held in NAIST on 24th March.
It was good weather and it was very suitable for the graduation ceremony.

This year, 3 master students graduated from Interactive Media Lab.
Congratulation on your graduation!!

At the same time, Shalika-san graduated in the autumn of this year received the NAIST Best Student Award. Congratulations!!!!

Thank you very much for your help in the past year.
In the mind what we learned from you, we will do my best to be a good senior to lead M1 students.

Graduation isn’t the end of a tough journey. It is the beginning of a beautiful one.
We wish you the very best in your personal and professional lives.

Thank-you and Farewell Party 2017

Hello, this is Ryosuke Mori,  M1 student in IMD lab.
M2 students held “Thank you Party and Farewell party” for teachers on 17th March.
This party is all planned by M2 students for the teachers.
It was held in Namba, and almost all the IMD members participated in.

First, we enjoyed eating, drinking, and talking freely.
After we got a speech from the teachers to the 5 people leaving the laboratory this time.


Speech by Kato-sensei

After the great speeches, graduating students gave presents for three teachers and Ueno-san(Secretary of our lab).

And Current students send presents to five people leaving the laboratory.


Gift for graduated people

It was a very nice party.
I’m very happy to be a member of this lab.

I feel like there’s a hole in my heart.
And, I wonder I can be such a nice student like them next year…

Anyway, congratulations!!
I wish their great success at the new place.

I hope this condition will be kept for a long time .

Internship at University of Oulu -final report-

I’m Yuma Ouchi, M1 student. I have finished internship for one month at University of Oulu, so I would like to make a final report on it.

As I wrote in the interim report, I learned the basis of multi-view stereo in this internship. The reason for setting this theme is that it is an important task to generate 3D models from 2D images of human in my research.

The above images are 3D point cloud generated using multi-view stereo algorithm. The left is obtained from 16 input images, and the right is obtained from 312 input images. From this result, we can see that 3D reconstruction with multi-view stereo requires many input images.

I would like to realize 3D reconstruction using as few cameras as possible in a large space. Therefore, it turned out that it is insufficient only with multi-viewpoint stereo approach. Therefore, it turned out that the current multi-viewpoint stereo approach alone is insufficient. Ultimately, Prof.Janne proposed a method using machine learning, so the direction that I should address in the future was clarified.

Next, I would like to mention Finland.  The temperature will be less than -10 ° C under the influence of radiation cooling phenomenon on sunny days. At that time it was the limit to walk outside of 10 minutes. However, life in Oulu was very comfortable. There was a shopping mall in one minute on foot from the hotel, and some stores were open late at night. And, above all, the cityscape is beautiful.

Although it was a short period, I had a valuable experience. I would like to engage in research by taking advantage of experience in Oulu.

SIG-MR2017

Hello. This is Matsui. I’m an M1 student in IMD Lab.
I attended SIG-MR which was held in Kyoto University from January 19th to 20th. This was a joint conference held in cooperation with CVIM, PRMU, MVE, CEA. As a result, I had the privilege of listening to many interesting presentations from various fields.

My presentation was on the first day. Surely everything was not perfect, but I believe it all went well considering the fact that it was my first presentation. I received a lot of questions and comments about our method and experiments. I hope the listeners were satisfied with my answers. 🙂

During the second day, I presented my poster and attended to lots of other poster sessions. I talked with not only researchers from SIG-MR, but also professionals from another conferences. Eventually, I got many additional comments from different aspects.

IMG_0105

Preparing the presentation was a hard task for me. Also, I personally felt that the trip to Kyoto University was hard due to it being a one day round-trip. It took so long time to go there and come back…

I will continue to work on this study with SIG-MR experience during the following days. I hope I can produce good results in the near future.
Thank you for time and I wish to you the best.
Regards.

Internship at University of Oulu -interim report-

I’m Yuma Ouchi, M1 student.
Currently I am studying abroad as internship student for one month at University of Oulu. Since half of the internship period has passed, I will make an interim report.

I belong to the group of Prof. Janne in Department of Computer Science and Engineering. In this internship, I decided to learn the basis of multi-view stereo while discussing with Prof. Janne. At first I don’t have confidence in my English ability, but I can somehow discuss with him because he can listen to my unclear English.

In my department, one room is allocated to about 2 to 4 people. Below is the state of my laboratory.

There are two Chinese students in the same room. For that reason, despite studying in Finland, I usually act with Chinese students. Last weekend I had traditional Chinese dishes at the student dormitory. I appreciate their support for everything around me.

Next, I would like to mention Finland. Before studying abroad, I was worried that it was too cold to bear. But It was okay as it was past the cold peak. Sensually it is almost the same as Sapporo that I went there one month ago. Having said that, the sunshine time in this time of Finland is too short (about 5-6 hours). And, because I am in the university during the day, I feel that I have not seen the cityscape of bright time yet.

It may seem like Finnish negative publicity so far, but actually I am enjoying including such things.

I will make a final report after returning Japan.

Internship at NARVIS Lab.

Hello, I’m Ryo Akiyama who became D1 student from this October.

I did an internship at NARVIS Lab. which is supervised by Prof. Nasir Navab for about two month. The project that I participated in there was using a projector as a surgery lamp in order to support surgery with a HMD. In the lab, they implemented the system that show AR born using an optical see-through HMD to support surgery. However, surgery lamp projects bright light equally, and in that environment, OST-HMD cannot product enough contrast, so it is difficult to see AR contents. In addition, if HMD shows just AR contents with overlaying to human body, we do not perceive that AR contents are inside of body. We tend to feel that AR contents are floating. Our idea to solve the problem is that replacing a surgery lamp with a projector, and control its brightness of AR area in order to get enough contrast and decreasing floating perception.

Before implementing that system in real scene, I implemented simple simulation to create projecting images when viewpoint of HMD user moves. This is my main progress during my stay. There are two window, left one is view from HMD user and the right one is simulated image for projecting. This time, we did not use real medical data to begin from easy situation. We used famous bunny 3D model as a projected object(this will be patient in the future), and simple triangle as an AR content(this will be AR bone or other medical AR contents). From HMD view, we see same triangle even when change the viewpoint. And right window creates image for projection from a fixed projector.

From here, I will tell you about few things in Munich. Munich is very beautiful city with historical buildings, and there are many transportation like train, subway or trams, so very easy to access almost anywhere in Munich. Also, during my stay, Christmas Market has began since the end of November at many places in Munich. In Christmas Market, Gluhwein(mulled wine. hot and sweet.) is very popular, and they are usually served with a mug. It tastes very good, and I got some mugs as souvenirs. I also went to Neuschwanstein Castle which is well known as a model of the Cinderella castle. It was snowy when I went there, so I saw the castle in the snow.

My days in Munich was not so long, but it was really good experience. I wish I can go to Munich again if possible.

Thank you for reading!!

SI 2016

Hello, your favorite D1 student Oral is here, again.

Between 15th – 17th of December 2016, I participated in System Integration 2016 conference held in Sapporo, Hokkaido, Japan. It was a national conference where you can see presentations prepared in Japanese only. So, I also had to do my presentation in Japanese, which was a thrilling experience. I believe for a foreigner, this kind of experience is quite a unique challenge and I will be honest, I enjoyed every little bit of it.

I introduced one of the works that I am doing in our laboratory, which is actually a research work belonging to Professor Yasuhide Yoshitake from NIFS in Kanoya. To put it simply, we are trying to increase the motivation and effectiveness in regular exercise methods designed for elderly by using gamification. To achieve that, currently I am trying to develop a rhythm game where the player is expected to control the avatar through squat movement and capture the gliding note symbols. It is a quite simple game both in idea and design, and currently we are interested in the effects of our approach on elderly. In February, probably I will be in Kanoya; helping with the long term experiments which we are currently planning.

Ok, enough talk about the work. Sapporo; Hokkaido in general, is a beautiful place with beautiful nature, delicious food and cute ladies. 🙂 As a foreigner, I recommend you to visit Hokkaido if you have the chance, but maybe you would go there during the summer. During my stay, it was almost always below 0 degrees and constantly snowing. Makes it fun if you like snow though!

As always, I am leaving you with a couple of pictures that I took during my stay. Enjoy!

Internship at University of Oulu -Final Report-

Hello all, this is Ryoko Kato from M1 student.
I finnished my internship in University of Oulu, and I returned to Japan on last Friday. I will write final report in Finland.

I belonged to Professor Petri Pulli’s laboratory, and I am a member of the research of the gamification that how technology can support activate isolated young people. Finally, I submitted the presentation file. Through this internship, I think can improve my English skill and deepen understanding of my research.

In previous article, I wrote about my days in Oulu University or Oulu City, So I will write Finnish culture.

(1)Design
Finnish miscellaneous goods and tableware is stylish and user-friendly represented by Marimekko, Iittala and so on.
I visited Ateneum, Kiasma, Design Museum in Helsinki at weekend, because I am interested in ergonomics and art.
I was surprised we can take the photos freely in museum, because it is different from Japanese museum. I think this is good thing because we can remind the details of art after we go back to our home.
Helsinki architecture is famous in the world, I saw it. There are some trams and cool architecture.

In this section, I will mainly introduce about Design Museum.
Alvar Aalto is famous architecture and designer in the world, he born in Finland.
There are some furniture were exhibited in Design Museum that Alvar Aalto was designed.

Furniture For Sanatorium

Furniture For Sanatorium

These furniture is designed by Aalto to be used in sanatorium. I cannot read instruction(because I can’t have enough time…), but I feel that these furniture is tidy and warmly.

In Japan, we can enjoy the arts using our eyes only in Museum. But in Design Museum, we can touch some arts, for example the telephone. Following photo shows rotary dial.(I used rotary dial in my parent’s house 20 years ago:) )

Rotary Dial

I felt the earphone is little heavy, and the heavy earphone reminds me of the memories of my childhood.

Now, how the the shapes of telephones changed?

According to this photograph, rotary dial changes to codeless phone and mobile phones.
In design museum, I could see the ergonomic designs.

I think I can feel Finnish culture and deepen understanding of Finnish culture.

In the end of this article, I’d like to thank professor Petri Pulli and IMD professors including Professor Hirokazu Kato for their support for my internship. Thank you very much.
