The making of Location Aware

Last Friday I was in Nottingham making a new piece of work as part of the Territorial Play event organised by Trampoline.

Using the same dual-GPS process as for Uncertain Eastside, I selected a route that took me through a variety of different urban environments including narrow streets, open wasteland, alongside large buildings and around the foot of the castle.

Wasteland with desire lines

Each circuit of the route (2.2 miles) took approximately 45 minutes to complete and started and finished at the Broadway Media Centre where the event was hosted.

We had a ‘project room’ that we were using as a base for various tech + mapping activities. After each circuit I returned here, processed the data and turned it into a .pdf file that my glamorous assistant Russell would take to the printers whilst I set out walking again.

By the time I returned there would be a new print put up on the wall combining all the traces from all the previous walks.

I only had time for 3 circuits, but my shoes seemed to think that was plenty.

I’m really pleased with the results and had some great feedback and conversations with the other people at the event.

To share a little something of the resultant drawing – and how it relates to the landscape – I’ve added some details from the drawing to the Google Map of my route. Click on the yellow placemarkers to see the image and read the associated text.

Walking Route for Location Aware

I’m currently working on the route I will walk for my piece Location Aware at this Friday’s Territorial Play platform event in Nottingham.

The problem is, I don’t know Nottingham, so I’m crowd-sourcing some input on a route I’ve put together from Google Maps.

If you know Nottingham at all, then I’d be grateful for any feedback on this route (larger version here, or click though for zoom-able version on Google Maps):

My first proposed walking route - what do you think?

My first proposed walking route - what do you think?

I’m looking for the following qualities in the final route:

  • Safe for me to walk with a PDA visible in each hand.
  • Total walking length of about 45 mins (I think the current one is about an hour).
  • Passing through a range of different built environments and open spaces.
  • Starting and finishing at the Broadway Media Centre.
  • Some interesting places to see on the way. Several times during the course of the day!

I’ll be going to Nottingham on Thursday afternoon and will hopefully get a chance to investigate the route ahead of the first scheduled walk at 11am on Friday.

Prior to that though, if you can suggest any changes to make the route safer, more interesting or maybe just different, then I’d love to hear from you!

Location Aware at Territorial Play event in Nottingham

I’ll be in Nottingham this coming Friday and Saturday for the Territorial Play platform event and symposium as part of Tracing Mobility.

For Territorial play, Pugh will conduct a series of walks whilst carrying a satellite navigation device in each hand. Glitches in the technology and interference from the physical landscape result in anomalies in the data recorded by each device. As the journey is repeated and the resulting data overlaid, unique generative drawings are produced that reveal relationships between the fabric of the city and the behaviour of the technology.

My first walk will start at 11am and you are welcome to join me (free, there is a sign-up list at http://locationaware.eventbrite.com/), you can also join me on subsequent walks, through until the early evening, however these will be unscheduled.

The generated drawings will be on display at the Broadway Media Centre [Google map] and added to throughout the day as new layers of data are collected.

Uncertain Eastside prints

The Uncertain Eastside limited editions prints are now officially available to purchase!

All the prints are A0 (841mm × 1189mm), signed, unframed and come in protective cardboard tubes – you will look after them now, won’t you?

The first batch of prints, rolled up, labelled and ready to go.

A set of 3 individual prints, each of one of the double-circuits of the Eastside regeneration area. Limited edition of 10, £50 per set.

I walked around Birmingham’s Eastside regeneration area in pairs of 90 minute circuits – the two walks in each pair happening one straight after the other. These prints make the traces of each walk visible.

Series B:

Detail from a Series B print: Moat Lane and the Bullring markets area.

The traces of all 6 circuits overlaid. Limited edition of 100, £15 each.

These prints show the cumulative traces of all 6 circuits overlaid on top of each other. It becomes a lot harder to pick out the individual circuits, but instead it makes the patterns of glitches visible and you can see how the physical landscape of the city affects the different parts of the drawings.

How to order

These prints are available through my online shop The Invisible Hand. Simply send me a message via the order form telling me which items you would like to purchase and I will then contact you back with confirmation and postage/delivery information etc.

Uncertain Eastside presentation for Performance Fictions symposium

Sadie Plant invited me to contribute to her presentation on ‘psychogeography and the city’ as part of the Performance Fictions symposium held at the Electric Cinema yesterday.

‘Performance Fictions’ is the fourth event in art-writing-research network created by researchers from BCU, Goldsmiths, Reading University and University of the Arts London. Article Press, BCU, will publish the papers and contributions from the various events in Spring 2010, to be distributed by Central Books. The volumes will constitute series one of Article Press’s art-writing-research publications.

After Sadie explored Birmingham’s historical rootlessness and uncertainty of place – its location at and function as, a junction – I gave a 10-minute presentation about the Uncertain Eastside work in progress. Below is a transcript with images.

___

When I graduated from BIAD about 3 years ago, it was to emerge into a lot of talk about plans for a brand new cultural quarter covering a chunk of one side of the city. I was concerned and confused by the apparent desire to suddenly plonk a fully-formed artist-led space into position amongst the warehouses.

My response was to wipe the streets of the designated area free of their existing names. And to add one.

The politics of regeneration is beyond the scope of today’s presentation, and I have little patience for it anyway, but I want to take the opportunity to use this image to show you how closely the borders of the City Council’s Eastside regeneration area are linked to the major traffic routes in and around the city.

In green, as we go up the left hand side is the ring road, going up, just out of shot to the roundabout where it meets the A38 on its way to spaghetti junction. Coming down via Corporation Street, the pedestrian routes of Hight Street and the Bullring area, and the across Digbeth Deritend back to the ring road. The criss-cross of roads and pathways are again being used to define parts of Birmingham.

In 2006 this was mostly all unknown territory to me. By 2009 it was still mostly unknown territory, but now with small incursions around Digbeth and Curzon Street. When I decided I wanted to return to some of the questions raised by the area’s regeneration, it was apparent that my first step should not to be to research it in an academic manner, and subject myself to all the spin, but to get out there and experience it directly.

I’ve spent the last month and a half repeatedly walking around the perimeter that defines Eastside, paying attention to how these spaces are being used at different times and by different groups of people. I’ve also been wrestling with how I might fit into the picture.

I wanted to document the process of walking this line, so on each 90-minute circuit I took with me 2 satnav GPS devices that I have programmed to log my position once every second. Rather than doing a straight-forward trace of my journey though, I was interested to see how the cityscape affected my position as seen by the machines.

Each of these lines joins my position as determined by the machine in my left hand to my position as determined by the machine in my right hand. The longer the line, the more they disagree.

Despite what we are led to believe, GPS is actually pretty flaky. All sorts of things can affect its accuracy. There may be 3 rather than 8 satellites overhead at that particular time; my body may be blocking the satellite signal; and large buildings and areas of concrete can bounce the signals around. All these affect the perceived position.

Looking at the results from any one walk I can see a whole host of different glitches and errors. To be honest, they’re what make GPS an interesting thing for me to work with.

Through overlaying the traces of several laps, however, you can start to filter out the anomalies … or at least start to read which of them are caused by the fabric of the city-scape.

Here’s the cumulative result after 6 laps…

Whilst walking with the satnavs I was given glimpses of other sorts of errors – biases towards the car, roads I couldn’t cross, residential areas the other side of seemingly impassable road boundaries.

However, due to restraints in using the GPS logging, I could only observe these in passing. I had to keep moving at a steady pace. I could speculate, but never investigate.

So, last Sunday I invited others to join me for an investigative walk. Nominally following the route around the edge of Eastside, but allowed the freedom to drift from it to explore things that caught our eye.

People are now starting to post their photos from the day online, and their accounts of what happened are starting to appear on blogs where the stories and viewpoints overlap. We also exchanged stories between us whilst we were walking along the route. In situ. It’s my feeling that we needed the 3.5 hours of walking to get to the point where we could gather around the ‘map’ at the pub and have an in-depth conversation about what it signifies. I find this happens a lot – that you need the group performance before you can get to the meaty discussion.

I guess that in terms of this symposium, we’re talking more about performed narratives, rather than performed fictions per se, but I’m expecting the edges to blur somewhat, especially as we move into the phase where we compile the accompanying publication of thus chapter of the project.

After unfurling some of the stories, we will gather some of the images taken by the participants into a publication with the aim of making a document to record this face of Birmingham before it reinvents itself again.

From here, Sadie speculated that this sort of drift along a route defined by roadways, exploring the details, progress logged by satnav devices, might be psychogeography 21st Century style.

Eastside Walk and Talk Event, Sunday 18th October

I’ve been walking many laps of the Eastside regeneration area over the last month or so, each time carrying a GPS unit in each hand, logging the positions they record and then converting the data into line drawings.

line drawing

The drawings are different each time. We knew that would happen.

What’s increasingly striking me though, is the amount of change I’m seeing in the landscape I walk through, even on the timescale of a couple of weeks: hoardings go up around construction sites; piles of rubble are shifted; graffiti is removed; and subways re-painted.

When I’m walking with my GPS units however, I cannot stop to investigate these things in more detail, or even to properly document them. I must keep walking past at a steady pace.

Curzon Street area nip and tuck

On Sunday the 18th of October I’m going to do a different type of walk, and I’d like you to join me.

Weather permitting, we will meet at the Old Crown pub (Corner of Heath Mill Lane and Deritend, Digbeth) from 2pm for a 2.30 start. We will then walk once around the perimeter of the regeneration area taking great care to stop, investigate, prod, document, tell stories about and explore things along the way. A no-frills walk takes about 90 minutes, so be prepared for this one to last 2 or more hours. No route march though – this will be very stop-start.

Bring comfortable walking shoes and clothing appropriate for the weather. Kendall mint cake optional. If the weather is too wet we’ll postpone things ’til another time. Announcements for rain-checks or otherwise will go out via my Twitter stream and via the Sunday Local show on Rhubarb Radio where I will, sometime between 12 and 2pm, be talking about the Eastside drawings I’m making. (’cos that’ll work great on the radio!)

I have the beginnings of an idea that I might collate the photos, GPS drawings and other documentations into a printed magazine so that there is some sort of a record of what things are like now (and how we remember them being in the past) that we can look at a few years down the line when everything will have changed beyond recognition. When we do the walk again, maybe.

Uncertainty in Southampton

I was in Southampton the other weekend and, having battled the Boat Show traffic to get into the city centre, I was amused to suddenly find myself in the middle of a shopping mall, in the middle of a public consultation exercise regarding Southampton’s plans regarding the development of a cultural quarter. There’s a .pdf with an outline here.

Guildhall Square

Before going to Southampton I’d done a quick Google for “regeneration zone” and found a damning article about the city’s architecture. Read it; it probably applies to where you live too.

David Lloyd in The Buildings of England described the reconstruction as being akin to an “up-and-coming Middle-West town with planning controls and Portland stone”. While the gigantic ships, those ribbon-windowed beauties that inspired a thousand modernist buildings, sailed to New York from just a few yards away, Southampton channelled the spirit of Iowa.Owen Hatherley, Southampton: What’s next for this major port turned mega-retail park?

No offence to Iowa, I have never been there, but 3 shopping malls have been built off the high street in the last couple of decades, as well as huge retail parks spreading out towards the docks and it is all becoming rather soul-less.

Southampton from above

I grabbed a satellite image of the city centre and roughly marked out some different areas (click to embiggen). The yellow strip is what I basically think of as being the high street. It’s where all the shops are focused. Sort of. The ones that are in different buildings with bricks and stone and stuff. You know what I mean.

The brown area is a land of shopping centres and decorated sheds. I know a lot of that brown is car park, but that really is huge!

The area in white near the top of the image is the area ear-marked for developments. Actually, this is a bit misleading: there doesn’t seem to be a delineated area for redevelopment in the same way as for the Eastside regeneration area in Birmingham, but rather a cluster of projects in roughly the same area. Also in contrast to Eastside, stuff’s happening where stuff already is: already in the white area is The Mayflower theatre, the BBC’s Radio Solent offices, the library, the civic art gallery, the guildhall, university buildings

I did a few laps of the area with camera and GPS units. Here are a few of the resulting images:

The walk was an altogether different affair from what I’ve been experiencing in Birmingham recently. For a start it was a lot shorter (about 30 mins per lap, rather than about 90), but also because it already felt kind of vibrant. I’m sure the park helped with this, but also I think because of the presence of the students and, noticeably, the smaller, independent shops and restaurants that inhabit this area. I hope these stay.

The other thing that hit home as I walked around was that I really, really miss The Gantry theatre that used to nestle in the shadow of The Mayflower. I only saw a couple of productions there before I left for university and it closed in 2001. If I remember correctly it was the sort of space where, before you pushed your way through blackout curtains to go to into the main theatre area, you could buy a big plate of chilli and a beer. This really twists the knife.

Sigh.

Anyway, to lighten the mood a little, here is a .kml file of two laps of walking so you can have a zoom around and play with the GPS traces. (Right click and save as. If you haven’t done so already, you’ll need to download and install Google Earth in order to open this file.)
