Waze – Map data collection with an exploration game approach

Samstag, November 28th, 2009

While projects like Google Building Maker or Google Map Maker enable people to contribute bricks for Google’s Digital Earth, other tools like a new Points of Interest Collector facilitate map data collection for the Open Street Map project. Hey, there is probably nothing wrong with people working on different map data silos – may not be ideal and may take twice as long, but maybe there is something else to map making than commercially motivated backgrounds – for whatever commercial reasons that may be. Most often, because no one really wants to pay for map data, right?

So it is quite interesting to see yet another approach to crowdsourced map-building. Waze, which labels itself as a “social mobile application” provides free of charge turn by turn navigation based on data that Wazers have already collected and are collecting right now. Starting from a blank map, the road network and Points of Interest are growing minute by minute as people contribute their traits and mappings. The Waze map emerges. I have yet to try this myself, but it must almost feel like the early days of the Open Street Map project. I am not sure about the initial idea and motivation behind Waze – but I enjoyed reading this bit on the Waze blog“In fact, in certain countries with no base map, users will literally be building maps from scratch – paving the roads entirely themselves, as they drive…”

To me that sounds like a call for wakening the explorer inside ourselves. And it works. I do feel like going out exploring today! Maybe not so much on the road – but wouldn’t it be great to waze the Great Outdoors? Map the trails you have walked, the walls you have climbed, the streams you have mastered and the slopes you have skied. Make it an exploration game – creating your personal Digital Earth. Your private universe.

Imagine, having your personal discovery map – a map that basically puts you back in time to give you a terra incognita experience, but customised for the 21st century. The map would just show the roads and tracks that you have already explored solely by yourself. Personal exploration by direct experience that is. No virtual exploration and discovery tools like Google Earth or Bing Maps allowed. In fact, these virtual globes should be banned since they take away all the fun of direct personal exploration if you can’t resist having a look. Statistics would provide your total life-kilometres, a spatio-temporal lifeline and your personal exploration road and track network. Boldly going where …. you have not been before.

Augmented Reality – A new interface to search, explore and discover

Samstag, November 21st, 2009

Augmented Reality technology must be nearing the gap – at least that’s what comes to mind when you discover two articles about the latest developments around the technology on the front page of Germany’s most important online news magazin, Spiegel Online.

Both articles are in German, but Google Translate results will get the core ideas across. The first article provides an overview of different use cases that can already be served by the technology. The author of the first article notes that what is still missing, is an application, which pulls things together to offer a one stop shop for augmented reality search, exploration and discovery. The second article looks at some applications like Mobeedo and Layar in more detail.

But it was a third article about the disruption in the Navigation Systems market that Google Maps Navigation and low-cost iPhone navigation apps like Skobbler have kicked off recently, which got me thinking about augmented reality in a different way – even though that third article does not actually cover augmented reality.

The authors argue that Google’s camera equipped Street View Cars are in fact Trojan horses, since capturing the images is just one aspect of the map data collection and processing that is actually happening behind the scenes and under the hood of the Google Street View cars. As the 360 virtual reality mapping mission progresses, each kilometre of geodata generates more information and less privacy. But how is this related to Augmented Reality?

Google continues to build the most impressive digital earth application out there – Google Earth. Thinking to the end, it may be difficult to distinguish the real view that you see when you are actually out there, exploring, from the the virtual reality view, generated by geodata. The next best thing to being there. So what is the difference between…

  1. …pointing your iPhone or Android device around and looking at the augmented reality camera view that displays overlayed objects in reality and…
  2. …virtually moving around a 360 virtual reality world, where additional information can also be overlaid?

Time. Obviously, Google’s virtual world cannot provide a real time view any time soon. Although first steps in that direction have been made by research groups, even Google consider it creepy and probably also a little bit too difficult – at least at the moment.

But if you don’t mind the time gap between now and when the images were taken, then Mapsicle, a cool new Street View library developed by New Zealand company ProjectX, will enable you to create and experience armchair augmented reality. Virtual tours that link up panoramic images and overlay information have been around for quite a while, especially in the real estate industry. But with Google Street View providing the ultimate roadtrip virtual tour and easy tools to overlay information and add links, like Mapsicle, things are taken to a new level. Mapsicle was even featured on the Google Lat Long blog and we may expect that there is more cool stuff ahead with this project. Why?

Because it is very cool to have a real world interface that complements the map as a way to search, explore and discover information as if being there. State of the art augmented reality apps enable you to check out what’s around your current position and put it in context of what you can see in a certain direction – soon we’ll find out what’s around the corner in the same photorealistic way – but without having to walk there if it is not worth it. We can virtually explore and use augmented virtual reality as an intuitive real world metaphor for search, exploration and discovery.
