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.

Page 66 of “Responsive Environments”, Lucy Bullivan. On talking about Usman Haque “he awaits the environment that is simply intelligent”. 1

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.

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.

The Emergent City. Stanza.

November 11th, 2008

stanza city

This text is a transcript of one of my talk about my work The Emergent City.My current work remains focused on the creative use of technology integrated into urban space.My areas of interest include investigating new concepts for the relationship of the physical body, emergent data and real space in the built environment. As an artist I am trying to create artistic metaphors for new creativity using new technologies and integrating new media artworks into the public domain. As an artist I am trying to create artistic metaphors for new creativity using new technologies and integrating new media artworks into the public domain. There are three strands of my working process; these involve; collecting the data, visualizing the data, and then displaying the data. The outputs from the online interfaces and online visualizations can be realized as real time dynamic artworks as diverse as installations, and real objects, made out of new display materials back in physical space. In all my work I try to exploit the changing dynamics of city life as a source for creativity and create meaningful artistic metaphors. I utilize new technologies and integrate new media artworks into the public domain as part of this ongoing research into the visualization of city space.

In essence I am researching data as a medium for creativity and how meaningful experiences of our cities may result. From a technological peprspective, I am researching sensors , motes, new display technologies and interactive architectures. This research includes investigations into…..Concepts for the relationship of mobile computing within urban space and the built environment.

The Emergent city is to be a group, a body of artworks that I am working on all connected by a central theme. As you know a city is a web of connected networks. In essence, the city fabric is a giant multi-user, multi-data sphere. The city is made up of traffic patterns, pedestrian patterns, bird flocking patterns. Patterns can be seen in the architecture, patterns in the buildings, patterns in the architectural fabric of the urban design network. All of these spheres can be represented by media and therefore by data within the digital realm. And all of this data can be interpreted and mediated. It becomes a matter of choice. Collections of data can be stored to be retrieved later. The mobile data infrastructure becomes a data source so powerful so interwoven that its scale can only be imagined as metaphor. The size and scope of such an archive, of such rich mediated data experience can support many projects. As such it can be interpreted via a variety of interfaces. Cities offer the opportunity for unique types of data gathering experiences via a variety of sources.

My objective is to ‘mediate’ data into conceptual artifacts. With this perspective there are many unimagined threads of data and connections that describe our world that can be explored through wireless mobile networks within which we can create artistic interpretations. There are various types of data can be re-imagined. This includes pollution data recorded via sensors in the street, to create audio files. Weather and forecast data, acquired via weather station equipment, this can be used and can create ambient soundscapes and morphing visualisations as the wind shifts direction or the rain increases. Noise monitor levels, and noise maps, create a symphony of true urban sounds that can be used to make sound reactive sculptures. So under this umbrella of ‘the emergent city’ project I have made a number of works that have move beyond the process of research, beyond what I term as asset gathering, into what might be alpha beta projects. An example of this is my URBAN GENERATION project. I have also made the online database for soundcities which now has 2000 sounds online line in it. So other artists can interface to it. Memory mapping. About traces and memories of urban space. Multiple viewpoints of data cities. The city also has millions of CCTV.

In essence the city is the biggest TV station in existence. Millions of hours worth of data are recorded every day by these cameras on city TV. One can take the sounds and images off live web streams and re-represent them thus creating new interpretations of the city in the process. The city already has a recorded source of data, CCTV is everywhere. Using data from CCTV, you can bring the outside inside. Selected feeds are collected from around the world in real time. These real time images are fed into a software system where a series of specialised channels rework these images. The channels are always on, and always changing, a constant view of the world changing and evolving around the clock. This uses specially created software and technology to randomly find images in real time from anywhere in the network, in this case anywhere in the world.The increase of technology infrastructure in the daily existence of a city means that technology will, more than ever be everywhere in our environment. Mobile data mining will be part of the fabric of the landscape. We will be carrying this data in pods, phones and ID cards. Everything is or will be tracked. CCTV, car sensors, tracking inside our phones and id card movement tracking in the guise of anti- terror activity. The patterns we make, the forces we weave, are all being networked into retrievable data structures that can be re-imagined and sourced for information. These patterns all disclose new ways of seeing the world. The value of information will be a new currency as power change. The central issue that will develop will be the privilege and access to these data sources. Uses of this information and data should allow rich new interpretations on the way our world is built, used, and designed.

So we need to imagine the city at a different scale. The possibility is to extend our imagination and enable that perception of the city as a dynamic network. We can now put systems in place that can re–employ our perception and thus create new understanding of how this behaviour unfolds. There are patterns, they are connected and the systems that evolve, can be simulated and acted upon. We can influence the process and the system and we can also create variables into this system that allows understanding of the bi-products of the system, the data and the resulting information Currently a research fellow at Goldsmiths Digital Studios.

I am scattering the city with sensors. Hundreds of them, some fixed, and some embedded, to access these data structures and to claim them for the public domain within the realm of social sculptures.I am trying to make smart networks that have data open to all, and not closed off spy surveillance oriented systems. The networks could be thought of as open social sculptures that can inform the world and create new meaningful experiences. Thousands of motes can be deployed across the city for gathering data in wireless sensor networks. Used in large numbers they can communicate with one another via radio signals across the network. They can reconfigure themselves, so that the network stays stable. The data is chanelled through a system to a point where it can then be interpreted. So the concept is to embed the city with thousands of motes to gather data for the creation of artistic artifacts. The motes can monitor sensors such as temperature, sounds, light, position, acceleration, vibration, stress, weight, pressure, humidity, and GPS. Motes and sensor boards can monitor the micro incidents of change in the city, the noise, traffic flows and people flows. The interactions of all this data, controlled via mixed up interfaces that can re-form and re-contextualise experiences in real time as social sculpture. Imagine walking out the door, and knowing every single action, movement, sound, micro movement, pulse, and thread of information is being tracked, monitored, stored, analysed, interpreted, and logged. The world we will live in seems to be a much bigger brother, than first realised. Its a world full of data that can help understand the fundamentals of our outside environment, and monitor the micro codes of our DNA, a world where we are liberated and empowered by data, where finally all of the technology becomes more than gimmick and starts to actually work for us.

So this is where I am at..scattering thousands sensors across the city and trying to figure this out.Sensity artworks are made from the data that is collected across the urban and environment infrastructure. I have a network of sensors which collects data, which is then published online. The sensors interpret the micro-data of the interactive city. The output from the sensors displays the “emotional” state of the city online and the information will be used to create installations and sculptural artifacts.These artworks represent the movement of people, pollution in the air, the vibrations and sounds of buildings, they are in effect emergent social sculptures visualizing the emotional state of the city. 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)l. Representations of these datasets will allow unique understanding of the urban environment and environment in real time. Motes are used to collect the data.

stanza

The ‘motes’ are tiny wireless sensor boards that gather data and communicate to the central server. The real world is monitored and the data stored in my archive retrieval system. Motes and sensor boards sense the micro incidents of change in the weather, the noise traffic flows and people flows. The interactions of all this data, controlled via interfaces that can re-form and re-contextualize experiences in real time. Sensity incorporates the holistic city system. The sense city is a city of, accumulated incidents of love, abuse and death. The micro incidents of change in the weather, the noise traffic flows and people flows. The archives of this data can be controlled via mixed up interfaces that can re-form and re-contextualize experiences in real time; to make emergent sculptures visualizations and sculptures. Sensity leverages the real time data city and represents it online showing the life of the system and the emerging changing bahaviours of the space. The data is the medium. Future cities will be merged real time connected up data cities. Sensity connects up networks of real time information flows. The results are mashed up cities and real time performative city mashings. The shared data space can overlap and there is a new space the space in between that only two nodes share. The aetheticization of the shared city space. I have merged collected data from various cities. The images below show an integrated architecture the space where the cities overlap and create a new architectural space. Technology. I now have several sensor kits both twenty nodes that can be placed up to 300 meters apart with GPS. I have made two versions of the Sensity interface software. One works with recorded data (ie recorded data) and one that works with the real time data, which means the sensors are switched on always and working through a router. The changing data is what affects what you see and experience. The sensors can monitor temperature, sounds, noise, light, acceleration, vibration, pressure, humidity, and gps. The sensors take a constant stream of data which is published onto an online environment where different interface can make representations of the XML and from this lots of artistic interpretations can be imagined.

Motes technical .Temperature responses for mts 310 series on mica 2

June 3rd, 2008

The temperature sensors in moteview on four of my motes show -273.15. The rest of the board ie light and sound is working. How do I get the temp working or reset it.

Did you “Reboot” into the new image (slot) that you OTAP’d?

This is required in order for the nodes to start executing new image.

You may choose any of the available slots where you want to store the

new image.

Please refer to the MoteConfig manual for details on OTAP.

http://www.xbow.com/Support/Support_pdf_files/MoteConfig_Users_Manual.pd

——————————————————

The temperature sensors in moteview on four of my motes show -273.15. The rest of the board ie light and sound is working. How do I get the temp working or reset it.

Response:

—————————————————————

It looks like you are able to query the nodes (i.e. they are running OTAPImage).

Which Motes are you trying to reprogram with the new code?

Which slot have you selected to OTAP?

Please check and make sure that you have at least 2.7V battery voltage on these nodes.

Response:

—————————————————————

Unless you had previously enabled the nodes to be OTAP’d you won’t be able to OTAP with new application.

What I would suggest is to bring the nodes and attach them to the MIB board and then program them using MoteConfig’s Local program tab. You need to chek OTAP enable box if you wish to OTAP them in the future.

—————————————————————

Response

May be I wasn’t clear earlier. You can use both CA and CB boards in

the same network. The main difference is that they use different power

control lines for temperature sensor. To get accurate temperature readings, you should Program the Mote attached to the CA sensor board (without jumper wire) with  “XMTS300CA__.exe and program the Mote attached to the CB  sensor board (with jumper wire) with “XMTS300CB__.exe

Response:

—————————————————————

It is quite likely that you have an MTS310CB board (look for a jumper

wire on the bottom-side of the sensor board).

The MTS310CA uses INT2 for temperature power control where as the CB

version uses PW0. It sounds like you are using CA code on CB hardware (or vice versa) and hence the Temp sensor never gets turned on and returns 0.

If you have CB board, then you need to use CB version of the app.

Question:

—————————————————————

We want the batteries to last longer.

How do we do this?

How long should batteries last without a change….

If they are in low power mode how long will they last.

I know know this is difficult to answer) but how do I get them to last longer.

Also do you have solar panel one can plus in to the motes for power?

Response:

—————————————————————

The high power (HP) version of the apps don’t duty cycle the radio and hence would deplete the battery in few days. The low power (LP) version of the apps draw an average of 330 uA current with MICA2 platform and when used with alkaline AA batteries can easily deliver over 6 months of battery life.

In order to make the batteries in the Kits last long time, you need to use them in XMesh-LP mode.

We do have solar panel implementation in our next generation eKo Pro series products that can deliver battery life of over 5 years.

“Gallery” by Stanza

May 28th, 2008

stanza Image

“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.

Crossbow moteview software

July 17th, 2007

If you can spell it out to me ( what the difference is ) please; his would be appreciated and I will buy a copy.  NOTE ammended 2007 sept…I did but a copy it cost £800 uk pounds and six weeks later crossbow made it freely available. Crossbow are very flakey with their support and process.

XMesh software

XServe – Server software

MoteView

Essentially Crossbow have taken a version of the open source tiny OS and from that point on will use that version as the basis of their OS.
Hence, they’ve fixed all the bugs, written more code, documented the software and fully tested it.

From now on, it’ll be their SW and not the OS version. The OS version will continue to be out there, but Crossbow now have their own version, under their control etc, etc. Then what they’ve done is to bundle all the elements of their own software together and provide a complete suite of software known as MoteWorks..

There are two levels of software & support (one with source code, one without);
MoteWorks Standard Edition

*Software licensed per user

*Software CD
*TinyOS source, XMesh, XOtap, XServe, MoteView binary

*MoteWorks Enterprise Edition

*Software CD (same as above)

*Source code for XMesh, XOtap, XServe through CVS access

*Bug fixes, minor version updates

So now, they are selling the software, not giving it away; however, for this, you get much better software and support.
Plus they’ll continue to development, improve, documents etc, etc ,,, something that will not happen in the open source academic world.
Additional  notes…. the copy I bought was full of small bugs,  but newer free versions are  much better.

Xml RPC: To stream xml and live data from sensors.

December 15th, 2006

Xserve:

Xml RPC command structure.

The X command API in xserve is presented as a set of XML RPC functions ( remote procedure calls)

A computer send an XML document to a specified Xserve command port (9003) and Xserve executes the command. After the execution the xml document is sent over the connection back to the requesting computer.

The complete XML RPC specs are at www.xmlrpc.com

xmesh.get_config: requests configuration from a mote
Using xserve web interface

NOTE:Run Xserve from /opt/MoteWorks/tools/xserve/bin/bin/ in order for interface to work

Go to browser.
http://localhost:8080
http://hostname:8080
Xsensor …can use this to see real time data. Before using make sure Xserve has started the XML server. That is ‘-xmlport=9002’ and one of ‘-xmlp’ ‘-xmlc’ must be turned on.
In cygwin run the following 2 lines:

cd /opt/MoteWork/tools/xserve/bin/bin/
xserve -device=COM7 -xmlc -xmlpost=9002

NOTE groupId =125
ALSO note maybe I need to try modbus: Xserve will provide a single flat address register map of sensor values that can be queried over the modbus interface.

Xserve provides an XML RPC interface to allow enterprise applications to issue commands either the network or the Xserve itself. The Xcommand methods are implemented through the Command Module Interface.

NOTE: Heart Beat Datasink.
The base staion is entry point to all data. A heartbeat can be set to rests MIB510 if it is not responding. SEE X mesh users manual

Note Sensor Board ID.
MTS300 Board ID (Hex) 0*83 Board ID decimal 131 …..Buzzer , Photoresister, acoustic mircrophone, and thermister;

The xml document is published to listening deveices through XML socket connection.
The XCommand API in Xserve is presented as a set of XMLRPC (remote proceedure cals). Xserve implements protocol pver TCP/IP to send XML back and forth.

see also http://plw.media.mit.edu/people/arikan/xmlrpclib/

Basic XML-RPC library for Processing. XML-RPC is a widely adopted Remote Procedure Calling protocol that works over the Internet. It creates connections between procedures that are running in different applications, or on different machines. This library is based on the Apache XML-RPC 2 Java implementation that uses XML over HTTP to implement remote procedure calls.
