Long time no see.

In Nov.1-5th, 2017 “Smart Illumination Yokohama 2017″( http://smart-illumination.jp/ ) was held at the elephant’s nose park, Yokohama We exhibited “light wave (hikarinami)”.
I made my own work for the first time and exhibited.
So I got so many things, my feelings increased and I became a long sentence poem, but I think whether the feeling will be transmitted sufficiently if you read it.

Please look at pictures of my work:
hikarinami hikarinami2 hikarinami3

Description:

Although the image of a sharp light is strong when it is called a laser, depending on the usage of light it can give a soft impression. In this work, the laser hits the object, you can see that the light reflected on the floor looks like a wave. I am glad that it makes me feel that things change not from one aspect to another, but how they look.

About my work:

I think that there are a lot of intense light like the live and the club seeing the laser beam that you see frequently.
laser
It is exciting and powerful. (And a bit dangerous)

This work uses a different usage.
By reflecting the laser, light appears like a wave, and it involves a complex pattern.
The same and slightly different light fluctuation.
It is good to be healed by gazing at the light which is repeatedly repeating, returning it like a wave.
It is okay to shake the shining rod and to repair that light like a wizard.

Enjoy interactive nature, lightly watching the light wavy, or laser itself is a light source that is hard to shoot so try challenging for shooting.
It is a work that various ways of enjoying content differ depending on experiences.

During the exhibition:

While supporting the explanation and experiences at most booths during the holding period, I occasionally leave the booth,
Observe how everyone will experience → update by the next day’s holding
I was repeating that.

It was not an interaction(gesture) that shake sticks on the first day (another operation method), and there was no explanation of how to use.

In fact it was a very late time to work on production and there was a time I was worried about whether I could be on time for the exhibition and it was not enough yet that it was not enough for the first exhibition, I was worried about the worried feeling that it could be taken as a boring thing.

But the Thai people who were exhibiting at the next booth were very kind and one person praised me.
Also, when guests actually open the visitors come visit me, give them a loud voice, enjoy people who keep looking for a while for a while, or who are watching how the mechanism is going.
Some people enjoyed it in their own way, others said that they liked it very much. As time went on, anxiety turned to self-confidence.

After a few days, it became a feeling that my work grew.
At first I did explain the work and the way to experience,
if guests do not do anything when they let everyone see the beautiful light without explaining the function to switch light especially to see the light, the repeater will come and shake the stick.
Then the people who did not know such a thing could “could do such a thing”, or “Oh Oh” and the cheering sounds as if they are very pleased, and as a conductor of the repeater this conductor It was a leading role of the.
At first it was a feature that was easy to put on, but it was very interesting without thinking myself that it would have such a big impact on the work.
Moreover, it seems that he liked the work itself very much, and the person who was shaking the stick explained to the other people how to use the stick. Then the person shook it, as the light changed, I felt a feeling that I was manipulating the light and got a different impression from when I was only watching, from the viewing works to the works to experience It seems that I was pleased with what changed.
And another person who saw it taught by the person who operated it and manipulated and manipulated by another person ,,, There was a repetition phenomenon that a person who was watching the figure from a distance came close to … There was something awake.

my booth is so small, but there are a lot of people and my work is not visible.

my booth is so small, but there are a lot of people and my work is not visible.

Is my work okay before the event? I was worried that I was enjoyed this much, I am sorry that the author is uneasy! I was sorry in my mind.
And, I also increased the desire to cherish and grow this work day by day.

I got a lot of grateful experiences to say so, the last day.
I applied for the Smart Illumination Award this time, but I have an awards ceremony for that award.

Judges around the applicant’s work around the open time of the day and will review it.
Though I was thinking of words to speak with judges as an early time, I was thinking about words, but thanking you very much, there are a lot of people who have already enjoyed themselves in the time of appraisal, so the explanation to the judges can not be done properly (explanation I was explaining to the person who is in trouble or asking questions from the visitors as well) even when I was doing) I wonder if I can be awarded, I was glad when I was able to do, but as a result it was indoor exhibition I received the Excellence Award.
(Actually, there was a conflict secretly that it would be fundamentally important to support and explain to those who were experiencing difficulties in explaining it well, but actually experiencing it on the spot.)


I’m so glad.

It is naturally nice, but it is after the awards ceremony.

Because the exhibition time was still left, when the commemorative photography ended and it was about to return to the place of holding.

Although I had her to talk to me, I was pleased with the feeling that the words I got to say are chesting.
“What I was exhibiting was pretty good, so I came to worry about winning! I was glad I was able to win, I am glad that we could talk about this because I was cheering.”
That is what she said.
That person said that although I was alone when I was alone, it was said that it was good that the children who were nearby showed beautiful lights in various ways.
I am delighted that I am so happy that what I have thought about here where I did not notice …
To be honest I’m just writing this sentence like this, even though I just wrote a sentence, I’m getting along well.

Again:

I wrote the comment again, there were many things I was happy about.

I was worried very much but what I made is very much accepted by visitors,
Thank you for giving us lots of thankful words,
Children and adults also wanted to try to manipulate the light themselves and enjoyed being able to line up,
A person who raises cheers whenever changing light,
Those who enjoy lighting excitingly by changing lights themselves,
People who look at beautiful and see for the first time,
People who always say “I can keep watching forever” after seeing it for quite a while (a few minutes to 10 minutes, etc.)
People who take pictures intentionally,
I was praised such as idea power that I did not have confidence, mounting power, etc.,
It spreads to spread other people to enjoy this work that he enjoyed, and by accidentally explaining to people around us that the people who were there were born through the work,
People who told me they wanted me at home,
It is so wonderful that I told you that I will definitely go see if there is a place to see the work next time.

There are still more improvements and things I’d like to try but I am very happy that I was able to move my heart so far by myself alone and I gained my confidence.

I got a lot of very glad words of cheering, so I thought about keeping this work more carefully and keep updating it to become a more wonderful work.

First of all, we have to proceed where we can exhibit next.
Please continue your encouragement.


view from the place

view from the place

Yokohama, the venue, was a place I lived at the time of my university, a city that I started living in and started living by my own family.
I was not familiar with college so much, I was working part-time at Motomachi in Ishikawa Town from Minato Mirai, where I got to have a good day with friends and get together. Perhaps if I were only a school, I think that my life was quite different depending on whether I drop out and go home.
In such a place I liked very much, including the atmosphere of the town and people, I was able to have such an opportunity in a memorable place and have had a wonderful time.

I know, although I did not get the best award, I think it is too strong feeling to write so far, but I wrote poem unintentionally because I got so many things for the first time.

explanation

explanation.I am pleased to make it.

Well, from now on I would like to develop this work and more opportunities to create such opportunities so I have to find places for presentation so I began collecting information in various ways, but I am in a fumbling state …

If you are interested, we would like you to feel free to contact us, this is what I said! Try out it! If you have something to say, I am glad if you can feel free to contact us.

Please contact me via contact,facebook(hi-farm.net),twitter (@mmlemon)

I made the Playlist on Youtube!

I am sorry that I could not afford so much time this time and I could not see the work of others so much …

Realtime laser by Beyond

Like this video, I found the way to conevrt video to laser in realtime, so write this article.
(I did it by etherdream before, but the quality of the scanner could not be used more reliably with practice than I thought.)

Required:

  • Pangolin Beyond(Ultimate) : enable “Tracer”
  • Virtualcam software like ManyCam

Overview:

  • Use Tracer function by Beyond that converts webcam input to laser in realtime.
  • Some screen area handles as webcam input by using Manycam.

Steps

Step1:

Get Pangolin Beyond. You must use Ultimate version of Beyond because you need “Tracer” function.

Step2:

Donwload and install Manycam.
https://manycam.com/
(ManyCam may install some adware, so you must uninstall adware and some doubt programs.If you avoid Manycam, You may download and install other application. I uninstalled adware.)

If you are good at Directshow, this may be useful:
https://www.codeproject.com/Articles/437617/DirectShow-Virtual-Video-Capture-Source-Filter-in

I explained using Manycam.I bought Manycam “Standard” license.

Step3: setting ManyCam

Launch Manycam and configure VirtualCam.

Right-click on the side by side rectangle → Desktop-> Custom Area and so on.
A rectangle appears on the screen, and you can treat that area as Webcam input.
manycam

Step4: open video

Display the image/video you want to convert to laser is located in the rectangular area.

Step5: Open Tracer

Open from the menu Edit-> Tracer. At that time, you should open it with Empty Que selected.

tracer_menu

Step6: open Webcam setting in Beyond

When you select from the menu, the “Realtime Video Tracer” window opens, so click the “Trace” button to open the Tracing window.
Open the Tracing window and click “Device”.

webcam

Step7: select Virtualcam

Select VirtualCam (“ManyCam Virtual Webcam” here) created with ManyCam etc. If the resolution is too large, the operation becomes heavy, so adjust it according to the PC specifications.

selectwebcam

That’s all!
By setting this, it is possible to laserize the designated range of the screen in real time.

TouchDesigner+Laser

Recently I began to touch TouchDesigner.

I do not get used to Node-based programming environment…
How about a for loop? What if you have a fine conditional branch?
Also Quartz Composer, vvvv, TouchDesigner. Although I bought a Commercial Lisense a while ago I kept not using anything but it was easier than I thought when touching TouchDesigner as a trigger, so I decided to start earnestly.

At first, I made something that reacts to the sound.

And I tried replacing it with a laser.

You can use etherdream in TouchDesigner. At last it will be a choice other than Pangolin as this will make it easier to make the beam steady and I am looking forward to it personally.

I am planning to strengthen cooperation between sound and external equipment from now on.

Shuhei Matsuyama’s blog is a good starting point to study TouchDesigner.

developping laser control software

I’m developing software to control laser beam because I get laser-related jobs gradually.
I want to control laser at will because I’m a programmer.(Of cource, I love to think what laser beam is attractive and to create laser beam and to operate it.)

I uploaded demo movie below:

I’m developing laser-analyzing app, that is receiveing picture(movie) via Syphon, and convert it to laser beam.
This app analyzes “Syphon” movie. So this app can convert to laser beam what type of movie via Syphon.
If you want to use Kinect depth picture.

In near future, I use in live scene.

MYOでレーザーをちょっと操ったことと気づいたこと。

こんばんは。
先日、1/30に前々からちらっと声はかけてもらっていたこちらのイベントでレーザーをやってきたのですが、せっかくなので先日届いたMyoを使えないかと思い立って実験もしてきましたのでその感想でも書いておきます。
こちらのイベントでした。Wombは相当久々。( http://iflyer.tv/ja/event/217868/

MYOとは筋電をとってジェスチャーの認識やら手の向きとかを取得できる腕輪のデバイス。
この動画で一時期すごい話題になりました。
https://www.thalmic.com/en/myo/

Kinectと違ってカメラでないので向きを気にしなくて良いのと、腕に巻くだけという気軽さからかなり使えるんではないかと思って注文しました。

すごい派手なところではこんな使われ方をしています。

まあとはいえ実際に動画のようにデバイスが使えるようになるにはかなりの苦労やノウハウが必要なのはいつものこと。
本番導入する前に現場で一度試してみよう、ということでとりあえず作ってみました。

やっていることは、腕のX, Y, Zの回転とジェスチャーを使って制御のon/offとキューの切り替えを実装して挑みました。
機能的には、
・Y軸の回転→レーザーの明るさの制御
・Z軸の回転→レーザーのキューのZ軸方向の回転
・手を握る→回転を使った制御のon/off切り替え(トグル)
・手を右へ動かす→次のキューへ移動
・手を左へ動かす→一つ前のキューへ移動
という感じです。
このジェスチャに合わせてMIDIを送るだけです。

で、やってみたのがこんな感じです。動画は朝方のクローズ直前くらいにブースから出てフロアで切り替えてたのですごいわかりにくいですね。すみません。

実際にやってみると複数ジェスチャを組み合わせてやるには誤認識が多くてあんまり使えなかったけど、Y軸方向の回転を使うのは比較的思い通りに動かせました。

気をつけたほうがいいなあ、と思ったのは、
・回転を使う場合、当然ながら人の可動域は体の柔らかさによっても異なるし、360度の回転なんてできるもんじゃないので反応する範囲をどう設定するかが大事。
・回転のon/offは初めはダブルタップ(親指と中指を素早く2回触れるジェスチャ)にしていたのですが誤認識が多かった。(手を右に動かすジェスチャの時に特に多かった。これは僕の動き方の問題とは思いますが)
・特にZ軸の回転をさせようと思った時に多かったのですが、人の体なんで当然Z軸の回転をさせようとしてもXY軸も動くわけで、ぐるぐる回すつもりが明るさが変わってしまうということがありました。

このへん改善してもうちょっといろんなものを制御しようと思います。

よかったのは、当たり前ではあるけどピークタイムでも混線もなく無事に動作したこと。VJブースがフロア前方で、フロアであれば後ろの方でも全く問題ありませんでした。

Arminのも仕組みとしてはわかるので改善してこういうのやりたいなあ。どなたかやりません??
