Copenhagenlayer Map View

Copenhagen Layer is the name of an environment monitoring initiative which shows you local conditions in Augmented Reality on your mobile phone. These environmental conditions are continuously sampled from the city by volunteering bike messengers who carry around tiny measurement devises – senspods – and upload this data in real time to the Copenhagen Layer data center.

Currently the project runs in Copenhagen only, so if you’re not in in the neighborhood you’re out of luck to experience the project yourself.

Good news: as of today the same data can be viewed on the map at copenhagenlayer.org. The site is still under development and we are actively experimenting with different visualization methods. As more data becomes available, more aggregate data may lead to richer views and more consistent data. At the moment only NOx levels are being used while the deployed sensor type is capable of measuring far more parameters, like COx, temperature, humidity and noise level in dB.

Tweeps Around 3D view

The popular Augmented Reality app Layar just got updated to a very exciting new version with support for a 3D Reality View and a couple of other neat features.

I’m proud to announce a new version of the Tweeps Around layer, with the following improvements:

• The images of tweeting people are shown in 3D in space, just as they are around you
• Support for the new native geotagging feature of Twitter
• You can now reply and post new tweets (status updates)
• Your tweets will be geotagged with your current location (optional)

Like to experience this yourself? Make sure you have the latest version of Layar installed in your iPhone (free download in App Store) or Android powered device (free download from Android Market).

You need a Twitter account with geolocation eneabled to send local tweets yourself (no worries, Tweeps Around will guide you through the process when you first log into Twitter).

Local tweet in Tweeps Around

Right now Twitter released their long awaited Geotagging API and activated the user interface for every user: Think Globally, Tweet Locally!

This allows every twitter user who uses a (mobile) device that is capable of determining their location, to annotate their tweets with exact location. This makes Tweeps Around so much more useful! Up to now, the location had to be parsed from the user’s profile location field, which some clients indeed dutifully update with the location of the last posted tweet. But this is often rather inaccurate, as the last update is kept when no location data is available.

Twitter: mobile geo activation screen

So, we will get real exact locations and – as can be expected – many more location annotated tweets. That is, if users are willing to activate the geotagging setting and use the feature. It is switched off by default, for privacy reasons, so you have to manually activate it under your twitter account settings (the mobile settings lead to just one activate button).

Be sure to check out Tweeps Around the coming days and let’s see how fast this catches on!

BTW: in Tweeps Areond, the officially geotagged tweets are indicated with Distance 234m, whereas the guessed locations are prefixed with a tilde character, like this: Distance ~234m.

Today Dennis Crowley from Foursquare gave an excellent presentation at  Mobile Monday, Amsterdam edition (#momoams on Twitter).

If you were there, you now know everything about the city as playground (pacmanhattan.com) and personal metrics.

I’m very grateful and proud that he took the opportunity to announce my Foursquare application for Layar, which allows you to use the most popular features of Foursquare from Layar.

What it is

Foursquare is a very popular social network game which integrates virtual social networks with the real world. Friends meet friends in cafes and bars and let each other know where they hang out. If you haven’t yet, it is definitely worth to check it out.

The Foursquare Layar app gives you access to the most frequently used features of the network.

• Show venues around you, including which people are frequenting them, who is the mayor and user tips what to do.
• Find nearby tips what to do and see at a glance what makes a location special.
• Check in to a venue and let your friends know that you hang out there.

Open Layer with foursquare

A basic version of these views is accessible even when you’re not signed in to Foursquare, which gives you an excellent opportunity to look around before jumping in and signing up (I’m quiet sure you will eventually plunge in and sign up to connect with your friends)!

These views are greatly enhanced when you’re signed-in. Then all venues where you or your friends have checked in are prioritized and highlighted. Tips from friends stand out. And you’re able to view what users have on their profile, which “badges” they earned and so on.

Give it a spin: open the Foursquare Layer on your mobile device.
