Over the course of World War II, the Dutch Navy lost seven submarines – six of which disappeared in unknown locations. Since then, five have been recovered, and the search for the final submarine, designated O13, is the subject of a documentary by filmmaker Wilco Pleging.

To accompany the documentary, a book has been published containing stories, documents, drawings, photographs and more. But this book, O13: Still On Patrol, is unlike any other. The pages have been made interactive with the Layar Creator and the publisher plans to regularly update the content with new information.

Right now, book readers can scan the book with Layar for access to copies of the original construction plans of the O13, new photos from the search for the ship and more. Each week for the next few months, readers can enjoy more new extra digital content by scanning pages with the Layar App.

It’s not the first time we’ve seen publishers enhancing books with Layar, but the regular updates are unique in this case. This is a great way to bring more interactivity to books. By being promised more content each week, readers will be eager to pick up the book again and again.

You may have noticed that the Layar blog has gone a bit quiet lately. Don’t worry, we’re still alive, but we’ve been hard at work these days on some new ideas that we think you’re really going to like. In the mean time, we thought we’d take a moment to pass on a few items that have come across our radar in the past week or so.

Personally, I’m a history buff so I would encourage you to check out the WW2Museums.com layer. It takes advantage of a huge database of locations related to World War 2, including museums, monuments, cemeteries and general points of interest from all over Europe and the United States. You can browse the database on their website as well - it may surprise you what you might find right around the corner!

We have a bit of company news to share as well, as we bid farewell to one of our earliest employees, Nanda! You maybe remember our “Meet Layar” profile of Nanda back in February, but in case you need a refresher, she has been Layar’s Office/HR/Management Assistant since nearly the very start. Nanda made sure everything around the office ran smoothly, and we will miss her dearly.

And finally, to leave you with a bit of entertainment and wonderment as we head into another summer weekend, have a look at this impressive AR demo. It’s another in a long line of intriguing hacks of the Xbox Kinect system, and it’s pretty amazing how well the 3D model sticks to the tracker used. And to top it all off, the model features live animation mimicking the motion of the person standing infront of the Kinect.

Enjoy that for now, and don’t worry, we’ll have plenty to share with you in the coming weeks. Just you wait.

Here on the Layar blog we have featured many layers that help us peer into the past with photographs and historical information. Augmented Reality has enormous educational potential both in and out the classroom, and one layer is helping visitors of old battlefields to envision history.

The layer “Battle of Franklin Sites” shows Layar users POIs associated with the historic American Civil War battle in Franklin, Tennessee. These include historic buildings, military cemeteries, medical facilities, locations of notable deaths, and even models of the front battle lines. Some practical tourist information, such as the location of nearby public restrooms, is also included.

Tourism officials in Franklin are hoping that using emerging mobile technology like Augmented Reality will help attract and engage visitors as the 150th anniversary of the war approaches in 2014. Why visit an old battlefield only to stand around and imagine what happened where? With this layer, visitors can use their mobile phones to see exactly where the battle lines were drawn.

Interestingly enough, this isn’t the only project using Augmented Reality in conjunction with the history of the American Civil War. The Civil War Augmented Reality Project is an effort by teachers in Pennsylvania to use the technology to enhance student experiences at historic Civil War sites. Along with mobile applications, the group hopes to install stationary “pay binoculars” which they hope will attract less technical visitors to engage with Augmented Reality.

These historical sites are prime targets just waiting to be enhanced by great Augmented Reality experiences. Soon, gone will be the days of tour guides saying, “A long time ago, important evens transpired right here on this ground.” Instead they will allow the visitors to see for themselves with Augmented Reality.
