Wireless sensor networks

FYI see Adrian’s response re McGill's Sensestage miniBee gadgets.

I know the guys who did the SenseStage work at McGill from Marcelo’s lab.  
They were nice folks, but not the best, and the research application was misguided.
This device was not useful to advance movement / gesture research at the TML.

To check my own assessment, I asked Adrian.

If you want to buy them on your own research funds, chacun à son goût :)
But I would prefer not to throw general AME or Synthesis money at buying such things
unless there’s a specific legacy need for a critical research project that will lead to an concrete outcome in predictable future.

Otherwise, let me suggest that we track the state of the art with Adrian Freed <adrian@cnmat.berkeley.edu>
and Vangelis Lympouridis <vangelis@lympouridis.gr> in USC
and get the best devices for the job under cost time constraint just when we need them.

Cheers,
Xin Wei

I am sure they are good for something but I can't use them for various
reasons.
They just aren't reliable enough unless the performers are out of reach
of RF noise from the
audience/ambient sources.

+ Slow, old atmega cpu with too little memory,
+ old accelerometer instead of full IMU.

There are lots of smaller form factor things in the works like SparkCore
and all the bluetooth LE things coming out.
The problem is you have to look at the fully integrated size with
battery, the additional sensors you actually want, the case
etc etc. Small is 6 months away (BLE), small and fast enough for serious
movement work is still a few years away.

Are these xBees any good?   would these be superseded by other common wireless microprocessors …?

We (at Synthesis and AME) are happy with the xOSC boards,
tho I do hope for a much smaller form factor.

[Synthesis] [TML] Founding documents of an atelier for ethico-aesthetic play: What we do. How we do it. Why we do it the way we do.

Dear Chris, Dehlia, Kristi, and Tamara,
(Hi Katie, Omar and JA, who know this well!)

Here are some texts that describe more completely how I envision what Synthesis is about, and how I would like it to be a home for radically empirical, ethico-aesthetic play.  I have developed a progressively more nuanced notion of play over the past decade of institutional experiment, funded thanks to the Canada and Quebec's more generous attitude toward experimental cultural work.

(1) The opening chapter of Poiesis, Enchantment, and Topological Matter (MIT Press 2013): 
gives a sense of how I see philosophical inquiry (which is not the same as philosophy as practiced conventionally in the United States academy) comes out of and feeds back into poetic, speculative practice.

(2) The second part of Chapter 7 gives an analysis of the political economy of the amodern atelier that I established in 2001 at Georgia Tech (in the Graphic Visualization and Usability Center, and the School of Literature Communication and Culture), but then moved to Montreal in 2005 with a Chair in critical studies of media arts and sciences in the Fine Arts and Computer Science.   My key meta-goal for the past 15 years has been to create an alternative ecology of practices based on collective, poetic knowledge practices.   I regard FoAM to be the lovelier sister to the Topological Media Lab.

This predecessor version links to a set of colour plates.

With the Synthesis Center I want to extend both the TML's central research streams and its model for how to go about doing that sort of transdisciplinary work.   To be very clear I came back to the States not to slip back into more conventional interpretations and practices of technology, art or humanities, but to harness Yankee enterprise to the much more radical work of ethico-aesthetic improvisation.   (I use radical both in its political sense and in the sense of William James’  radical empiricism.)

(3) Here are two one-page letters written at the invitation of the President of Concordia University about art practice versus art research.  They are not the same.  Many confusions abound here at Herberger as well.

 

(4)  Here’s the Synthesis Center pitch.   I invite your help to polish it before sending it up to the Provost and Engineering Dean. --- in the coming week




(5) Working ethos


(6) And finally, a letter that I share with people who want to study or work with me. 

Hope this gives you a more complete and substantial understanding of what I would like us to do, and why I would like to do it in certain ways.

I sincerely hope that after mulling this over, and considering that this has already actually flourished in two contexts, you will feel inspired to help me realize a third and even more beautiful atelier here at ASU.

Looking forward to working with you!
Xin Wei

Re: wearable x-osc biometric prototype

Seriously, how do we think techniques of observation together with techniques of performance? I know it may be confusing to use those pair of terms -- observation and performance...

we need a better vocabulary that retains some of the mechanisms of entanglement from quantum mechanics, but not this dualism.

[Synthesis] Portals needed

Hi!

We need portals supporting concurrent conversation via common spaces like tabletops + audio… (no video!)
not talking-heads.     It may be useful to have audio muffle as a feature — continuous stream audio, but default is to  “content-filter” the speech.   (Research in 1970’s … showed which spectral filters to apply to speech to remove “semantics” but keep enough affect…)

Maybe we can invite Omar to work with Garrett or Byron or Ozzie to install Evan’s version in the Brickyard and Stauffer and iStage as a side effect of the Animated spaces: Amorphous lighting network workshop with Chris Ziegler and Synthesis researchers.

BUT we should have portals running now ideally on my desk and on a Brickyard surface.  
And that workshop remains to be planned (October ??)
And possibly running also on the two panel displays re-purposed from Il Y A — now moved to Stauffer...

Xin Wei

[TML][Synthesis] Plant-Thinking Meeting/Seminar: discuss Marder, November 1 - Dec 19 ?

Hi Michael, everyone,

All great! 

I’ve been talking with Oana and most recently Omar about the vegetal studies research
From Omar it seems that most of the interested folks are away or too busy in September.  And October there are other events (e.g. Listen(n) @ ASU; lighting animation workshop, Einstens Dreams workshop) planned related to Synthesis or TML. 

It’s a good idea to do it on a weekly basis.  But instead of stretching over a whole semester, how about we concentrate the Marder-based part of the seminar into 1.5 months during a period when people are prepared to really grapple with the Marder.

To take the reading of Marder seriously, I think it’d be necessary to do this in person, or as synchronously as our portals can deliver.   And we need time for each one to prepare himself/herself with absorbing related works.  I would strongly recommend some of the Aristotle and Goethe.   ( to make time we invest worth the investment. ) 

So our — Oana and my — suggestion is to prep readings and exchange references etc. in vegetal studies stream
now, and do the actual readings  of Marder over seven weeks: November 3 through Dec 19.   
We recommend 
Week 1 Chap 1
Week 2 Chap 2
Week 3-4 Chap 3 & 4
Week 5-6 Chap 4 & 5
Week 7 Papers and Crits (double long session)

It’d be great to aim to deliver some substantial multi-format responses — on the order of a paper, short video, sketches of experiments that really synthesize the insights form the seminar.


Here are two key starting operating rules for this game :

• Avoid allegory — not the depiction of “what plants look like" but how plants grow, and experience dynamical existence.   

• Avoid as radically as possible anthropomorphizing .


Perhaps I can come mid November and mid December.
On the other hand my duties this Fall may well be so heavy that it’d be easier if Synthesis hosted this theoretical phase of the joint TML-Synthesis vegetal studies research stream in Phoenix.

Suggestions?
Xin Wei

Hi all

There is some interesting work in sky lights in amplifying light amplitude. Can I suggest someone take a look at that area?  Networked Prisms might be an interesting approach for instance.  Perhaps they could be servo/stepper motor controller to redirect light streams into different parts of the space. Modeling this would be an interesting exercise. .

I’m happy to review the techniques that we investigated, all of which involved more labor than available without access to maquiladora hands.

It’s worth Matt or Kevin posting the architectural techniques that are in actual use for light guides.  Apparently the solutions cost nontrivial $ or labor.    James Turrell has apparently made some study of this ...

The building is specially built for that purpose.

But pinholes do work too, and presage quantum mechanics.  Hence this could be another turn in the endless spiral between art, techne, and science.

RE: [Synthesis] networked cameras; potential response to activity vs actual activity

Cooper, if one of those black GoPros are available, may be we can find them useful under certain scenarios. Below I have a few network cameras along with their pro and con features.

Pro: wired and wireless camera with IR for night vision, pan tilt action, 2way audio, 1280x800wxga
Con: no POE

pro: POE, 2 way audio, wxga
con: no wireless, no optical zoom

pro: high resolution, POE, 2-way audio
con: fixed focus and zoom

pro: high and multiple resolution, POE, 2way audio, focus and zoom, supports RTP/RTSP/UDP/TCP/HTTP protocols
con: dome design, no pan tilt

Subject: [Synthesis] networked cameras; potential response to activity vs actual activity

Given Tain, Cooper and other folks’ findings, IMHO we should use wifi networked cameras but not GoPro’s.  (Can we borrow two from somewhere hort term to get the video network going?)  Comments on networked cameras?  
But let’s keep the focus on portals for sound and gesture / rhythm.

Keep in mind the point of the video portal is not to look AT an image in a rectangle, but to suture different regions of space together. 

Cooper’s diagram (see attached) offers a chance to make another distinction about Synthesis research strategy, carrying on from the TML, that is experientially and conceptually quite different from representationalist or telementationalist uses of signs.  

(Another key tactic: to eschew allegorical art.)

A main Synthesis research interest here is not about looking-at an out-of-reach image far from the bodies of the inhabitants of the media space, 
but how to either:;
(1) use varying light fields to induce senses of rhythm and co-movement
(2) animate puppets (whether made of physical material, light, or light on matter).

The more fundamental research is not the actual image or sound, but the artful design of potential responsivity of the activated media to action.
This goes for projected video, lighting, acoustics, synthesized sound, as well as kinetic objects.
All we have to do this summer is to build out enough kits or aspects of the media system to demonstrate these ways of working and in the formate of some attractive installations installed in the ordinary space.

Re. the proto-rearch goals this month, we do NOT have to pre-think the design of the whole of the end-user experience, but to build some kits that would allow us to demonstrate the promise of this approach to VIP visitors in July, students in August, and to work with in September when everyone’s back.

Hi all,

GoPro cameras are small, light weight, feature loaded, and are designed to be put under extreme conditions.  However, as they are not built for long-term use,  they have battery issue, overheating issue, and Wifi range issues.  Battery last less than an hour, and if we connect a source of electricity the camera will overheat and turn off once a while.

I also found ways to stream full video into a web browser or VLC media player (https://www.youtube.com/watch?v=RhFzrYBXItc) and a Mac app controlling and doing low resolution live previews (https://www.youtube.com/watch?v=au5Yi6y-LmE).  Unfortunately, most of these solutions are for low resolution previews.  Trying GoPro cameras in Max/jitter might still be a very interesting and challenging project, but we can also consider different options.

For example, wifi network cameras can be another good choice.  They are designed specifically for long-term live streaming without being connected to the computer.  Whenever the camera is connected to power source and network, it doesn't even need to be located near the computers.  Image below shows my previous project that used two network cameras in an outdoor environment.
