New Technological Art Award 2012, een internationale kunstwedstrijd van de Stichting Liedts-Meesen In 2012 organiseert de Stichting Liedts-Meesen Update_4 in het kader van het project Zebrastraat en in navolging van de eerste drie Update-biënnales.

In Update_4 wordt de filosofie van de vorige edities behouden maar leggen we nieuwe accenten. In het verleden gingen de tentoonstellingen gepaard met de New Technological Art Award Liedts-Meesen die meer en meer op de belangstelling van de kunstenaars en het publiek kon rekenen. Onze focus ligt nu op de presentatie van deelnemers van de wedstrijd NTAA en bestaat uit:

-een grotere bijdrage van nieuwe technologieën in de kunst
-een verhoging van het aantal genomineerden van 10 naar 20
-een presentatie van één naar drie locaties in België : de Zebrastraat in Gent, La Cambre en iMAL in Brussel

Uit de meer dan 300 inzendingen waarvan 20 kunstwerken geselecteerd werden, vallen een aantal typerende thema’s te traceren. Ondanks het feit dat onze dagelijkse perceptie in een grote mate gedomineerd wordt door virtuele werelden en onder invloed staat van de eigentijdse technologie, kunnen verschillende werken onder het landschappelijk genre gecategoriseerd worden. Opvallend is evenwel de verwerking van diverse parameters die het kunstwerk via een technische transfer veranderlijk en de beleving ervan multisensorisch maakt. Mapping betekent in deze context niet zozeer een cartografische variant, maar includeert eveneens het flaneren, cruisen of dwalen. In een gegeven geografie vertaalt zich dit vaak in een (mechanische) choreografie waarin parameters als licht en geluid expressief gemanipuleerd worden. De luciditeit in een aantal werken kent een tegengewicht in de reflectie over eindigheid, dood en in een enkel geval opent dit zich cynisch en hyperbolisch tot het contemporaine euthanasiedebat. Items als identiteit en communicatie vormen een belangrijk inhoudelijk substraat waarin gegevens als sociale netwerken, privacy, hacking, spam verwerkt worden. De interactiviteit bij vele inzendingen doet een beroep op een actieve toeschouwer die zich vaak geconfronteerd ziet met keuzemogelijkheden of beslissingen die men dient te nemen.

THE ARTISTS STUDIO AS LABORATORY

August 2nd, 2010

THE ARTISTS STUDIO AS LABORATORY FOR THE FUTURE: “TRANSPARENCY”

I am developing the idea of studio as laboratory and extending previous versions by inviting members of the public to be involved in the process and the experiments. The studio will also have live CCTV broadcast and live data feeds.

Artists are like scientists they ask questions and find answers in peculiar ways….guided by research and process development.  Most artists, like scientists do stuff, they make things to question the world. They often speculate, researching difficult issues in a general direction in the way they see it with specific outcomes, these outcomes may or may not be art.

From the real to virtual and back to the real is a theme that has had my attention for five years and the idea is embedded in the works I am currently making.

This project will take place in the Barn at Lanternhouse, as Stanza creates data scapes in an Open Studio.  The residency is about exploring the artistic process, being transparent about the process and the development and production of new work.

The “open studio” mirrors the process of the project, with material and philosophical process being available to witness throughout.

Stanza exhibits real time data network at Decode: Digital Design Sensations. V & A Porter gallery

November 22nd, 2009

Stanza is in this show…Digital Design Sensations. 8 December 2009 – 11 April 2010.

Using custom made sensors in the V & A Porter gallery and around the city. 20 custom environmental sensors units measure, light, noise, sound, humidity, and temperature….this data is turned into a online real time visualisation of the space.

Stanza’s work “Sensity V & A” uses environmental sensors scattered all over the museum and the city to make visualisation and sonifications. Literally painting with data these works open up a discourse about networks and surveillance technologies. The ownership and interrogation of public domain space is opened out where anyone can view all the data in these networks. This is used by stanza to make artworks but it is of equal interest to urban designers, city planners, and architects. Stanza’s main point is to question the social political fabric of the landscape around us. This work aim to reclaim the city which is remade as a real time virtualised space belonging to all. The work is interactive, real time and responsive; it is also available online.

The Victoria and Albert Museum. The exhibition will be centred in the Porter Gallery. The exhibition will explore three themes. Code as a Raw Material will present pieces that use computer code to create new designs in the same way a sculptor works with materials such as clay or wood. This section will look at how code can be programmed to create constantly fluid and ever changing objects. The second theme, Interactivity, will look at designs where the viewer directly influences the work. Visitors will be invited to interact with and contribute to the development of the works, many of which show designers playing with the boundaries of design and performance. The final theme, The Network, will focus on works that comment on and utilise the digital traces left behind by everyday communications, from blogs in social media communities to mobile communications or satellite tracked GPS systems.

The ‘environment’ in these projects is created from a wireless multi nodal multi sensor network that is in place. The network emits live data via a proxy server and the online xml data gateway represent a live communication flow of the city space. This impression and this part of the work is what I term asset gathering and in this case they are constantly gathered into an online system ready for interpretation.

The online interfacing of live real time sensors networks allows a communication with environment, with real space in the present. Control mechanisms of ownership and rights access are opened up my making the data available in the public domain. These real time impressions can be modulated from online interfaces to physical sculptural interpretations.

The data is remade real again as physical objects interpret the virtualized readouts. The analogue is made digital and the digital can be formed into a variety of output devices. The data can be represented as online interfaces like I have made (Sensity , House, both online), or by triggering the technology in the physical world, ie sensors, Leds, displays, robots etc. Sensity can trigger buildings relating to whole cities, or vice versa. The flow of the data can be set to affect the behaviour of the output environment.
The data environment that is created is a mapped on top of the space, a virtual data map or the real world.

Other artists are also allowed access to this “back end city, real data city and they can make their own “Sensities”. In this way the data is open sourced. From any Sensity network numerous artistic interventions can take place. In fact the whole city can be represented, and all artists can make multiple work from this “The Emergent City”.  A city of sculptures re-presenting  real time space.

Networked Cities By Stanza. Sensity project. 2004 – 2010

Within Sensity there is now a loop from the real to the virtual and back to the real.  This notion of playing or manipulating with a malleable form (data) is made possible as each stream, each node, each sensor, or even the entire network can be communicated with using this xml online gateway.
We have seen rich shift in relational and responsive interactive works and the move away from gallery as a venue for art to the use of architecture and public domain space in the last twenty years….stanza

In an age of global warming, so many artists are still using the architectural space as a coloured light bulb. As we burn more fossil fuels the light are flashing on and off. Sensity be made more physical on output to represent of the growth of the city as an experience in the real world away from the screen. A city representation of the fabric of city space end the emerging patterns caused by these data flows. An art city can be made where the data powers the wind turbines, the data changing the solar panels that change the lights. Loops of real time data change the meaning all the while changing the  input and output  which is (e)merging into a new space.  Also  see my new works Tree, Sonicity and Capacities.

Robotic Wireless Sensor Networks

January 27th, 2009

In the last decade, Wireless Sensor Networks (WSNs) have been successfully deployed to perform numerous automation tasks such as environmental monitoring, surveillance and inventory tracking. By introducing actuation capabilities (in particular controlled-mobility), robots have the potential to improve the capabilities of existing WSNs significantly. Recent advances in robotics as well as the availability of inexpensive robotic platforms have made it feasible to develop hybrid networks in which multiple mobile robots interact with each other and other static sensors to perform complex tasks. On the other hand, design and implementation of such hybrid systems bring forth new algorithmic and systems challenges related to coordination, planning, and resource management.

The goal of this workshop is to explore the algorithmic and systems aspects at the intersection of robotics and sensor networks. We seek work in a variety of areas including:

  • Development of hardware and software platforms
  • Experiences from deployments
  • Resource allocation algorithms
  • Novel research challenges and applications
  • Localization and route planning
  • Sensor tasking, control and planning

Sensity: An Urban Scale Wireless Sensor Test Bed.

October 23rd, 2008

copyright stanza artwork image London

From Sensity by stanza…2004.. The sensor network can be moved from urban to rural setting and different types of visualization can be made depending on the environment. Sensity is an open social sculpture that informs the world and creates new meaningful experiences. Sensity is also a highly technical project that will give vast amounts of information about the fabric of our cities. By embedding the sensors like this we can re-engage with the urban fabric and enable new artistic metaphors within city space. The sensors are positioned across the city. Custom made software enables these sensors to communicate will one another in a network over a proxy server in real time.The data can also be used to create visualizations in an open source environment. Other online users can also re- interpret the data and interrogate the various sensors in the network as this is open sourced as well (see xml streams). Representations of these data sets will allow unique understanding of the urban environment and environment in real time.”

“Gallery” by Stanza, is a dynamic public sculpture viewable over the internet.

May 28th, 2008

"Gallery” by Stanza, is a dynamic public sculpture viewable over the internet.

“Gallery” by Stanza, is a dynamic public sculpture viewable over the internet. Gallery describes the space, in this case the upper gallery in Plymouth Arts Centre, England. Made during an artist in residency project in situ in the gallery space during feb 2008.

The gallery interior has been made virtual and placed online. “Gallery”, is part of a series of process led experiments in data visualization within the context on an art gallery. This is an experimental engagement with data in the art gallery using sensors and CCTV. Stanza asks , “what happens during the process of visiting the gallery as a dataspace”; ie what happens to the gallery and what do the visitor do?

The sensors are used as real time recording devices to gather information about the sensory behaviour of the real space. The gallery becomes the artwork formed by the emergent real time data in the space.
The gallery laid bare as a work of art. Gallery proposes that the data is art. The art is a real time flow of the things around us that allow our senses to invoke understanding. The gallery space becomes the art described by the shifts in light, temperature and noises in the space over time.

Sensity in Italy Festival at Share IT. The art of environmental data

March 21st, 2007

ddcPIEMONTE_SHARE_FESTIVAL | TORINO, 23 – 28 GENNAIO 2007: From over 200 submitted works, an international jury shortlisted six works that were exhibited at the festival, from which one prize winner is selected.

Sensity was selected but they just set up a projected version rather than the live sensor network. Like with many other festivals, there is one prize only that is not tied to a specific technology or genre but rather to their combination and to the expression of ideas.

A series of artworks based on connecting city spaces. The results are visualisations and sonifications of real time spaces using my own wireless sensor networks and environmental sensor technologies.

Sensity artworks are made from the data that is collected across the city. The sensors interpret the micro-data of the interactive city or responding city space. The outputs from the sensors networks then display the “emotional” state of the city online, in real time. The information is also used to create offline installations and sculptural artworks. Several artworks (sonfications and visualisations) have been made connecting up space and cities.

All the artworks in this series by Stanza use data from the real time environment. A new city experience results based on the mash up meta data from these multiple cities streams. Sensity leverages these real time data city streams and represents it online, showing the life of the system, opening up the system, and the publishing emerging changing bahaviours of the space.

As all things becomes connected and networked, my concept will be become a system that senses not just the city but the whole world. Eventually sensors will be linked to give a real time global visualization. ~ Public domain data resource for art and environmental monitoring.

 

Crossbow Motes. Details of experience to date. 2004 – 2006

April 9th, 2006

Crossbow Motes.

What follows is a sort of diary / journey of my experiences of dealing and researching new technologies at the fuzzy edge where ‘stuff’ is getting developed and marketed to end users as research tools. The technology in this case is Crossbow Motes.

My interest and work with Crossbow motes (Mica 2 wireless board and sensors) and wireless technology goes back to early 2004 when I went over to Crossbow head office in San Jose and then attended a workshop in Boston in late 2004. For the workshop which costs over $500 dollars, you have to turn up owning or having ordered the technology,I actually wanted to evaluate it or at least see if it worked before I bought. I was looking for a technology that could fit my concepts (live real time data from a sensor network represented online for monitoring public space) and you have to start somewhere, however I paid upfront for the course and the technology , booked the flight from London, and got myself to a hotel in Boston USA.

It should have been a clue as to how difficult XBOW motes actually are. Out of 200 people at the workshop of which they said ten people would turn up to the free two hour session the day before (for the pre install). Well what I mean is, the clue should have been in the pre install day. Nearly every person or group, who had previously bought this technology needed to be shown how to install them. This audience included some navy seals, software engineers with PHD’s and all sorts of BSC and MSC graduates working in professional fields, ie hardware and software engineers. That is nearly everyone who had bought this couldn’t get it to work and needed their hand holding.

Anyway I went ahead and bought the kit at the workshop except the director of Crossbow couldn’t get mine working and he eventually gave me his used mib 510 board.

Its three years I have been messing around with these motes and there are some simple truths.

The first is this is expensive, the second is there is hope offered but failure is always close at hand, the third is your on your own.

I also wonder out of all the people that bought/buy these kits off Crossbow Technology who has actually to used them successfully. If anyone has can you write to me. I did ask crossbow for a list but they wouldn’t give me one. How many of these kits are deployed somewhere and working, or are they all left in dusty cupboards; my guess is the later.

Not only is it difficult to appraise what they should do, they don’t even do what the company promises (more on this later) but to try to develop your own ideas you have to read one of five manuals (which I did) this isn’t the problem, I mean at least there are some manuals. The problem is lots of the stuff is either not true or misleading.( the online forum is useless.)

Maybe I just ask the wrong question, however for three years my question has been the same. Can I get the data online using motes. I want to make real time online environment with the live data, not the local saved data. And after much questioning I was told use XML RPC. The answer to this has always been yes, but how?

They actually sold me software which they said does this out of the box. Well I can tell you and them it does not. It does not take XML RPC into flash for example. The version of XML RPC is proprietory and unique to Crossbow. Believe me it took months to figure this out. ie it’s a non standard version. I repeated the same question after I bought more stuff and they said I would now need to develop either a bridge or a PHP or CGI script in order to do this. (Which I have now also achieved as of 2007.see below.)

I asked them for examples or to at least show me that you at Crossbow have done this and their reply was to say that the code is Crossbow property ie proprietry intellectual property. OK what does this mean. Well first it means that the product doesn’t do what they say it does. Second it means either they are still developing this and also that they weren’t prepared prove to me that this worked. Thirdly it meant that I still hadn’t got my sensors blasting out data online over a network so that I can manipulate it.

However this isn’t the point.

The distributors in UK Willow and Crossbow in USA all said I can get real time data online to my website using the software they sold me for £800 pounds, err that’s why I bought it. They said it is built in. I made several requests about this and they assured me before I purchased that it was. Anyway you can not get realtime data to be presented to an online source using the kits and the software they supply you with. What they said is not true and as such is misrepresentation.

However, I did get my real time data but only after having written my own custom software which was mote proxy bridge in java. (Thanks to Eamonn) There is also way to do this via PHP and postgreSQL , but they didn’t help with this. In other words, you have to do a lot of your own software development to get this to happen, so be prepared.

The other issue with the motes is that I am always having issues restarting the program Xserve and trying to establish re -connections. In other words getting them running is one thing, keeping them running is another.

And of last month (mid 2007) Xbow announced they are now giving the software Moteworks away I bought this from them two months before for £800 ie $1600 us dollars. (No Joke) from their UK distributor Willow Technology. ER can I have my money back?

Recently I updated from version 1.4 moteview to version 2.0 and my mote bridge stops, working. They probably have updated their XML structure, so I rolled back to an earlier version. Well OK I here you say its the cutting edge of technology….er bleeding edge. So my bridge was re-wrote and updated again so I am now running version 2 of moteview with my own mote proxy.

I also bought a “stargate” wireless gateway (It cost £700 pounds via UK Distribution Willow Tech). This was advertised with built in micro wireless camera, err they could have said what it was. The built in micro camera was in fact an external USB Logitec webcam, this is what I got when I opened the box. They charged about £120 pounds $240 dollars for this webcam. The other thing about the “stargate” is it needs a regular power supply. It should be solar or battery powered. It makes no sense to have a battery unit for a wireless sensor network for remote monitoring. (True I can adapt it) At this price I should have just bought another laptop, and that’s what I recommend to anyone else..

There has not been one stage in this process when I have felt like I have had good service either off Willow ( Xbow UK distributors, although Willow tried their best, since their interest is making a sale in redirecting products that come from the USA with 100 percent mark up) or from Crossbow USA who I have dealt with directly.

Although I am still pursuing this project and my research, (I have started so I will finish)…this is more of a warning. Really I feel like should just ask for my money back with all this as it feels like sales misrepresentation.

You see I actually went to San Jose head offices from London and told them what I was going to do and what wanted before I started to invest my time and money in this, this was early in 2004.

Maybe all the researchers use other peoples money so it doesn’t matter and nobody speaks up; but this is just a word to those that might even want to invest in this. WARNING; look at any other wireless technology for sensors platform and avoid Crossbow Motes, maybe gumsticks are better, or build your own. Anyway you have been warned.

Oh, one more thing, I even bought housing to protect them, this does not fit properly and you have to break solder connections to get them inside, and they arent waterproof. This felt like more money wasted.

To conclude you have to do a lot of your own software development to get real time online visualization.

I have also been doing tests for continual running, mainly battery life but also stability and data polling. So far thirty six hours is the longest period I have had my sensor networks running without either a re-start or some other related health issue. Well maybe there is a memory leak in moteview 1.4. Also on this endurance testing during the last month of this two motes have now stopped working in my system. This means that they are fairly unstable for anything beyond “play” development.

Some positive points

I now have written my own custom software which was mote proxy bridge in java to get real time data online. I have tested this now and I making several online real time visualizations. A version mote proxy middle has been made. Current Version 1.23

There is also way to do this via PHP and postgreSQL though opening ports, I have also done this and an online PHP kit Vers 0.9 has been developed.

I am still trying to develop with this, for my Sensity and House project. Its part of my AHRC creative fellowship and I have now set up my studio ie main operational headquarters in the Digital Studios at Goldsmiths College University of London.

Maybe Crossbow would like to support me by giving me a complete set of the new motes and sensors boards with GPS that can network over larger distances.(Imotes and Iris), so I can continue my research..

 

Wish list

Smaller more stable motes.

Data of much larger distances.

Plug in solar power cell to power them.

Stargate with solar polar or battery

Some decent housing that easy to clip wrong and fits well.

Much better technical support.

Easier set up.

More sensors available that can just clip on and piggyback the set up.

ALSO

A mote with Ethernet that just clips into a new work ports and configures to send data…that would be cool.
