Physical computing workshop
The workshop was organised by “Erich Berger”:http://randomseed.org/ (of “7 Mile Boots”:http://randomseed.org/sevenmileboots/ fame) who brought in Helen Evans & Heiko Hansen of “HeHe”:http://www.hehe.org/ to give context and direction to the technical process.
My intention was to avoid the screen for the duration of the workshop, to concentrate on simple interactions between sensors and outputs entirely independent of a desktop computer. But I ended up staring at microprocessor programming languages like “PBasic”:http://stage.itp.nyu.edu/~tigoe/pcomp/stamp/stamp-programming.shtml and “JAL”:http://sourceforge.net/projects/jal while making lots of LEDs blink.
A lot of it brought back memories of school; circuit diagrams, resistance calculations, it was great to refresh the memory. We spent a lot of time translating circuit diagrams onto breadboards, and programming both “PIC”:http://stage.itp.nyu.edu/~tigoe/pcomp/pic/index.shtml and “Basic Stamp”:http://stage.itp.nyu.edu/~tigoe/pcomp/stamp/index.shtml microprocessors.
Erich is now setting up a Physcomp lab at Atelier Nord to support art/design projects in Oslo, maybe alongside some regular meetings (entitled Atelier Nerd :). There are many projects that I would like to pursue, this should be a great resource.Posted in Adaptive design, Conferences, Interaction design, Technology
The easiest way of linking photos to locations is to combine the time-stamps from both a digital camera and GPS receiver or other location-aware device. If this data is available (over the same period of time) it’s possible to process a series of images and location tracks to stamp each image with location metadata.
Here are a few resources, papers, projects, guidelines and other geo-reference issues.

h3. GPS track and waypoint extraction
Transferring data from GPS devices can be problematic. If this is going to work in a wider, collaborative context there is a need to make guidelines for this process. It is also really important to make sure units and timezones are correctly set up on all software, so that no translation happens as the data is converted. Exported data also tends to be messy, with mixed tracklogs and waypoints, which for us meant a lot of hand-tweaking.

h3. Extracting EXIF data
To get a handle on the photographic data we need to look at the embedded EXIF information, which contains things like capture date, time, exposure and aperture.
* “Python Exif Parser”:http://pyexif.sourceforge.net/

* “EXIF metadata extraction in java”:http://www.drewnoakes.com/code/exif/
h3. Content metadata guidelines
In order to standardise the sharing of geographic information (tracklogs and waypoints) we need to think carefully about the formats used. We initially intended to use locative packets, but have ended up using GPX format alongside some custom XML for time and photo information.

Social filtering for online forums
“Yayhooray”:http://www.yayhooray.com re-launched with new features and functions, and what looks like a rich environment for writing, browsing and discussion. As far as I know it’s the first forum built to use the buddy list as a form of content filtering: to increase the signal to noise ratio in the content.
Here’s a bit of Yayhooray history:
Built by “skinnyCorp”:http://www.skinnycorp.com in 2001 as an experiment in online community. Along with “o8”:http://126.96.36.199/search?q=cache:1nd31d-exeAJ:www.cotworld.com/main/journal.asp%3FJournal_ID%3D539 it soaked up some of the users from “Dreamless”:http://www.dreamless.org/, the ‘design forum’ that reached critical mass and became its own “worst enemy”:http://www.shirky.com/writings/group_enemy.html at the end of 2000.
Originally it was built to manage itself through a levels system; allowing users to earn administration responsibilities (similar to implicit moderation systems employed by other forums like “metafilter”:http://www.metafilter.com). It worked well at a small scale but led to cliques forming around the early adopter’s own social networks.
The levels system evolved into a points system, allowing anyone to award points to anyone, on a limited (one a day, one person a week) basis, similar to karma systems adopted at “slashdot”:http://slashdot.org/ and “kuro5hin”:http://www.kuro5hin.org/. This briefly led to multiple account scams, and ended up in the ‘point orgy’ where ‘points were swapped rather than STDs’.
In the end, both systems were abused, subverted and widely discussed, often taking over from normal discussions and swamping the site with controversy. Many regulars left to other places, some seeing closed, invite only communities (like “humhum”:http://humhum.be) as the only option left for humane, creative discussion.
Yayhooray, in this latest version, is setting itself up to deal with these problems by globally filtering the content through a buddy system, rather than explicitly administering the content and user reputations. This applies to the entire site including the categorised discussions, blogging interface, links database, buddy lists and search.
The most obvious feature is a meter on the left hand side, which allows 4 different filtering settings:
* you and only you
* you and your buddies
* you, your buddies, and their buddies
* every user on Yay Hooray!
This applies a filter to the entire site, including user lists and search, which took me a little by suprise. The site is effectively meshing off into small, interlinked communities of interest, based on individual social networks and collaborative filtering.
In my case, buddies are mostly people that I have met, talked to, or seen invest time into making things: initiating photographic threads, dealing with social issues, administering creative collaborations, giving good design critique…
Logging in now (using ‘you, your buddies, and their buddies’) I see a small subset of the overall forum, focused on these parts of the discussion. Given that the filter is so prominent and usable, it is also possible to jump out into the chaos of the full site.
There is also a useful, if somewhat harsh, system that censors posts and links based on a list of people that you class as ‘enemies’! Being based on proper XHTML, CSS and DOM technologies means that censored posts are easily toggled on and off.
On the downside there will most likely be confusion and clashes when different groups that don’t mesh with each other, but have completely different experiences of the place, come together in a single thread. There will also be more repetition, or double posts of content gets repeated amongst different groups that are out of sync by virtue of the filters.
To fully appreciate this you need to invest time in it, and to build up a network of trusted buddies. YH can be hyperactive and annoying, it must be difficult for a new user to become engaged. The filters are perhaps most useful for long-time users looking for relief from ‘worst enemy’ problems.
Because it has become an adaptive social platform, and has the potential to be subverted and shaped into many different kinds of system, I will reserve judgement for now, and make a new report soon.Posted in Adaptive design, Information architecture, Information design, Interaction design, Social, Technology, Usability
Mobile outskirts workshop
There is a “workshop wiki”:http://locative.rixc.lv/tcm/workshops/index.cgi?Location_Norway and “media archive”:http://aware.uiah.fi/packet/?id=TCM that we are attempting to keep updated via fairly limited wireless coverage.

h3. Barcodes for spatial markup and control
“Spotcodes”:http://www.highenergymagic.com/spotcode/index.html use a very “simple circular barcode”:http://www.highenergymagic.com/spotcode/symbols.html, to mark objects for interaction with a camera equipped phone.
* Requires a “small application”:http://www.highenergymagic.com/spotcode/download.html running on a Series 60 phone to scan barcodes with the built in camera
* Each barcode can currently store 42 bits of data using technology modified from iris tracking and wavelet technologies (as far as I understood)
* Potential for more data by increasing the number of rings, but current setup is a compromise for low quality cameraphone cameras
* The mobile phone application can determine position of phone relative to barcode by the elliptical distortion of the circle, could perhaps be used for quite accurate tracking with multiple spots
* The phone application communicates via bluetooth or gprs, using the barcodes as triggers for interactions
* It’s coded ‘close to the hardware’ to use the video input to do barcode calculation in realtime: Java/Symbian apps don’t have an API to realtime video input
* In use commercially via “Bango”:http://www.bango.net
h3. Bluetooth mapping
“Reverend Rat”:http://www.spy.org.uk/ratblog/ demoed his 10 Watt bluetooth receiver, 10 times more powerful than a 35 mile 802.11b receiver, and 100 times more powerful than a Bluetooth dongle.
Not particularly interesting in itself, but using it from a high vantage point he might be able to map out usage patterns in urban areas, or track the flow of people and devices.

h3. “Encounter bubbles”:http://www.seansavage.com/encounter-bubbles/
A visualization tool based on “Mobster”:http://scott.lederer.name/projects/mobster.html that enables users to explore their social encounters in new ways. Designed to be an open framework on which locative (meaning location-based) networking applications can be built.
A social network tracking and visualization project. The project distributes a set of small stickpins, each of which uses limited-rage infrared data exchange to remember every other pin that it encounters. When pin wearers come to a central location to view the accreting network, they see a thousand circles on a plasma display panel, each representing a pin.
The first of these services is aimed at public transport users in Turin. While on the move, travellers can find dynamic information on mobile screen-based devices while at home or at the office, people can find the same information on physical display units. The other service is a personalised and flexible scheduling system to help Interaction-Ivrea students organise shared laundry facilities; mobile and stationary tools give them constant updates about the progress of their laundry cycle.
Affords the social creation and excavation of proximity history. At its core is a simple question: Who was near who when?

Creative Crossings workshop
Some of our ambitions were:
* Investigate transformative use of space and place
* Address gaps in infrastructure: access to standards, material frameworks and technology
* Instigate a triangular network: tried and trusted network practice
* Pursue research and practice, less engineering
* Explore relationships between media, gaming, locative, mobile, visual media
Anne Galloway has posted our collaborative summaries from the workshop and my full notes are here, until they can be put on the collective server.
The discussion is continuing, and the next informal meeting of participants is happening at ISEA 2004.

Urban GPS experience
It’s possible to use the “GPS Map 60c”:http://www.garmin.com/products/gpsmap60c/ in an old “Marimekko bag”:http://www.marimekko.fi in a mobile phone pocket just small enough that the aerial sticks out. In this way it can be placed in windows of buses or cars without it sliding around, and I can walk around without looking like a geek or getting mugged.

In short, GPS doesn’t work well in dense urban environments like most European cities. This is from the perspective of a pedestrian confined to the pavements (sidewalks) and public transport. From a few experiences whilst being driven around, it seems to work well in a car, probably because of the clear sky area available in the middle of the road. Inclement weather and green trees also seem to be problematic.
In these last few months, attempting to record a good quality database of tracks to geo-locate my photographs, I must have looked really odd. Face in device, stopping on street corners, stopping in the middle of street crossings and scrambling to grab the front seat of the bus. Discovering that GPS doesn’t just passively work is a great disappointment and my dataset is clouded with gaps and anomalies.
h3. Some other observations
* Fast turns when using public transport or car result in wild deviations: re-aquiring satellites is the problem
* Need a road that aligns with at least 4 satellites to get an acceptable track, anything else and the errors can accumulate
* Glass buildings can result in ‘reflections’ of position, eg jumping to other locations due to reflected signals
* I sit on the outside or front of buses: to get a wider expanse of sky area: I am constantly aware of sky cover
* The relative position of satellites is beginning to have an effect on the side of the street that I walk on
* Walking in the middle of the street: had a couple of near misses with cars – the moving map is just too engaging
* I would like an explanation of the lost track calculations: this device seems to use the last-known bearing and velocity to guess new tracks when the signal fails. This is very unreliable and problematic as it fills the map with phantom trails
* The track can be more useful over time than the (base) map: it shows my personal space and personal routes, I know where I have been and can use it to retrace routes or places. Popular routes build up in blackness and thickness. Home area becomes an abstract scatter plot of routes, but it’s very familiar
* Stored waypoints are really useful for getting large, general bearings on location: zooming out and seeing a relationship to two known landmarks can be really useful in an unknown area
