Google is giving away free Google tents tonight at Where Camp on Google's main headquarters in Mountain View. Starts at 10 a.m. tomorrow night too. This is a picture of the tents they are handing out (they have tons of these tents, just tell them Scoble sent you). To learn more about WhereCamp, go to This photo was taken with a Nokia N82 cell phone in night mode. Did pretty good, if I had a tripod it would have even been better.

This will all make sense in a minute.


Basically, I've been carrying a GPS around a lot, inspired by Aaron Parecki's (@aaronpk) constant GPS data stream:


Quite a while ago, Aaron set up an automated check in system based on GPS coordinates. The system allows one to check into locations without having to load an interface. This was about 2 years before any of the geosocial systems were readily available. Parecki was not living in Portland, and his audience was small.


Now, social sharing platforms are hot, but they still require user action. This means that one still has to pause social flow to look down at a device, poke a few buttons, and check in.


Parecki's system sends SMS messages depending on quadrants of Portland, or pre-defined locations. When I go home, I get a message that I've arrived at home. Instead of actively checking in, I simply dismiss the message. When I leave SE Portland and enter Downtown Portland, I get a SMS message telling me that I've changed locations.


But there's a lot more to the social equation than just automatically checking in. GPS is useful for a number of things.


For instance, it reduces the need for text messages. Instead of needing to send a text message like "I'm late!" or "stuck in traffic", I can simply look at Aaron's GPS any time to see if he'll be late for a meeting, if he's having trouble finding a parking spot, or if he's left the office.


But that method of co-location negotiation still requires user action. In an effort to reduce that, Parecki set up what has proven to be my favorite part of the entire system: proximity notification.


Now, instead of having to look at Parecki's GPS map, the system detects when we are within a certain distance of each other. I usually know when Parecki is near when I get a text message that says "you are 0.4 miles from aaronpk". When I get a message that says "you are 0.1 miles from aaronpk" I know that he's arrived, and I can go meet him.


This structure reduces the need for two common co-location drags: the message "on my way", and the message "here". Both messages require user action and imputs. These actions can be costly, especially when struggling to split concentration between driving and texting, or the sheer inability to text while on bike.


A few nights ago, Aaron created bridges as locations, so that one could be checked into them as well. I got the text message you see above on my iPhone when I crossed the Burnside bridge.


A bit of history on this:

I've been writing and talking about this sort of technology for a while now. At WhereCamp 2008 in Portland, I wrote about the possibilities and opportunity of Geolocal Autosubscribing RSS Feeds.


I began the session by drawing a big grid of Portland’s quadrants on the white board. I labeled them NW NE SW SE and N, before drawing circles all over the place. The circles represented ranges of ‘hearing’ that a mobile device might have to RSS feeds. I pointed out that as one progresses from street to street, quadrant to quadrant, one’s phone should understand this and automatically subscribe the user to the geolocal RSS feed for that area. That way, data can be very relevant and contextual to the area.


Full post:


Aaron Parecki has developed a framework that does just this. Locations are defined by circles on a map, and SMS messages are triggered to send when one enters into the area defined by that circle. One can set neighborhoods, areas, and blocks.


This Sunday, Parecki developed the ability for others to send geonotes. That is, an outsider can open up a Google map and drag a circle over an area. Then one can leave a message to me or Parecki and it will be texted to us when we physically enter the radius of that circle.


For more on this, come to our talk at Open Source Bridge called Non-visual location-based augmented reality using GPS data


The presentation will cover the topics discussed above. It will also highlight the advantages and disadvantages of visual and non-visual augmented reality. We’ll cover alternate types of augmented reality techniques and how they have been saving us time in the past few months. We’ll demonstrate how we’ve been merging available technologies with custom programming to create location-aware social networks with custom proximity notification. Finally, we’ll describe other uses for location sharing, such as automatically turning off house lights when leaving for work, and wayfinding with piezoelectric buzzers. Privacy and data transparency will also be discussed.


Privacy is another big issue. One does not always want SMS updates, open GPS map data, or text notifications of another's proximity. In our case, it works well because we work together frequently. If, on the other hand, we were to get proximity notification texts all the time because our commutes were similar, the data fuzz would be annoying and unvaluable. We're the only two people using the system right now. Anyone with more than 10 active friends on Foursquare or Gowalla and has probably experienced a Push Notification nightmare of endless texts.


Here's a definition: One's location is valuable to another if and only if that location or person is socially relevant during that time period. The basic case here is the meeting. Person A and Person B need to meet each other, but GPS data is only shared between them when they have a scheduled meeting. When the meeting ends, the data wall closes off, giving them back their privacy, kind of like a wormhole of temporary transparency between two people. This solves the problem of extreme bouts of "checkin-ism".

Whether the gutter and cistern had been originallylined could not be ascertained. In the latter a portion of a mill-stone was found. Along the corridor we discovered two leaden bowls and a largeiron knife. It will be seen by the Plan that the main approach to Section Awas by the great corridor in front of the house. 14. The stokehole to No. 10. The north side of this chamberwas so mutilated that it is difficult to determine its relation to thecorridor (No. 13), but we are of opinion that the south wall ofNo. 9 extended to that of the court-yard, thus dividing the corridorfrom the stokehole, with simply an opening in it for the gutter beforementioned to pass under, hence the entrance to the stokehole wouldhave been through the south wall from the outside. In this chamberwe found a brouze chain, fragments of glass, a bronze bangle, and PLATE E.

Bravo. La tradizione della musica popolare, da un po' di tempo, sembra tornata in grande spolvero. C'è gente che si diverte a ritirare fuori dal cassetto i vecchi stornelli, con tutto il loro carico di complesse ritmiche ridondanti. Tra quelli che cantavano c'era anche un meccanico in divisa: aveva un tatuaggio che diceva "Mamma ti amo". Grande
