EDvent Calendar: Day 14 (Augmented reality)

For those who don't know about it, augmented reality is the name given to any technology that can overlay the real world with information or data. There is huge potential for learning in Augmented Reality; if you've got a smartphone, download one of these apps and have a play. If you'd like to learn more about how students can use AR as a publication tool, go here. At the frivolous end, we can turn roadsigns into monsters:


...while at the more serious end, AR can be used to see what the world used to be like...


...before the Christchurch earthquake (CityViewAR by Hitlab):

...to bring textbooks to life (Aurasma):


...or make meaning out of the world around you (Wikitude):

Infographic: mobile phones and teenagers

This is a pretty comprehensive run-down of mobile phone use by teenagers. Some points to note:

• 40% use phones to do last-minute study before exams
• 88% text during class time (despite this being 'banned'- are you winning the war on this?)
• Scary: 25% have been at one end of 'sexting' or the other. Woah!

Three cool features of the latest Android phone

Here's a nice video about NFC (near field communication). The latest Android phones, equipped with NFC, allow people to pay for purchases using credit card details loaded onto their phone. As the video shows, you can tap the point of sale terminal with your phone and have small purchases deducted from your account. http://googleblog.blogspot.com/2011/10/more-google-wallet-merchants-are-live.html

The second cool thing about NFC is its ability to share content using 'Android Beam'. It works a bit like bluetooth, and allows users near each other to share just about anything: videos, website links, contact details, images etc. Just tap and go.

The other cool thing about the latest Google phone? You can unlock it by smiling at it. :-)

Layar AR gets a re-vamp

Layar has provided users with a very usable augmented reality platform, but its recent re-vamp offers some really nice new features. One of the most interesting is the ability to use AR to share real-world content like magazine articles with Twitter or Facebook followers. Another (less earnest but still just as much fun) application is to interact with things like cafe menus and wine lists. The only difficult part of using it seems to be choosing between the strawberry and lemon margarita during happy hour.

Zappar: augmented reality app

Here are two examples of the augmented reality app 'Zappar': one where a 2D poster for a film turns into a 3D animated advertisement for a film:

...and another one that could get a bit out of control (if you're prone to hearing voices)...

QR Code Craziness

After a few exchanges on the MLE discussion group, I kicked myself into action to explore something I've been meaning to play with for a while: QR codes. I've been aware of them for a while, but a few exciting things have crossed my radar recently that have opened my eyes some of the possibilities they hold for learning. The first was this video about Tesco's homestore set up in a Korean subway. Commuters, too busy to visit the supermarket, can scan the QR code of a product on a billboard and have that product delivered to their home.

Cool stuff eh? So I got to thinking, why don't we do the same thing for our school? Instead of QR codes for food and household items, why don't we link the code to apps related to learning in the Android Market? Y'know, nourish the brain rather than our desires to eat processed food? I threw a few screenshots and QR codes into Gimp and knocked up this poster which is now on noticeboards around the school:

Students can scan the code of an app they like (algebra quiz, Spanish vocab, periodic table, e-portfolio uploader etc.) and be taken directly to the market so they can download it. It's difficult to make out, but down at the bottom of the page is a QR code to connect to the school wireless. Scanning the code connects a user to the wireless network (including a password if necessary) and opens a browser and prompts them to enter their username and password before heading out to the internet. QR code craziness!

Edit:

For the people who have been asking for it, here's the youtube video of the poster in action:

Six steps to rock and roll greatness*

• Find a phone, and piece of paper and a marker pen.
• Take the marker pen and draw a keyboard on the piece of paper.
• Position the phone so the camera can see your keyboard.
• Turn on the Piano Reality AR app
• Bang out a melody on your portable, paper piano.
• Practice dodging the paparazzi.

Open Source Physics: Tracker

I discovered this neat tool when learning about the physics of Angry Birds. Not only does Tracker identify and track objects frame-by-frame through a video, it also records and graphs this data for you. It comes with quite a few experiments installed and, in the hands of a good Physics teacher, would form the centre of a very interactive unit on motion and movement. I can imagine students the world around grabbing their cellphones to record video of all manner of objects 'bouncing'. Hmmm. Does my glass of chocolate milk fall at the same rate as a bowl of noodles?
It's an easy-to-use tool that allows students to become better askers of questions and designers of experiments instead of becoming better memorisers of someone else's data.

Hold the world in the palm of your hand

One of the winners at last year's New Zealand Open Source Awards was Ghosts in the Form of Gifts by Bronwyn Holloway-Smith.

This project used Open Source machines - the RepRap - to recreate physical artefacts from Te Papa that had been lost or destroyed over the years. The finished files for the artefacts were released under a Creative Commons licence so that anyone who wished to could create their own exhibits. Most of these represented items of significance to Pacific cultures.

Wouldn't it be great to be able to use public domain 3D models like these with students wherever and whenever we liked? Of course. Enter AndAR, which stands for Android Augmented Reality. This app allows anyone with an Android phone to download 3D model files and, using a black and white printed marker, use Augmented Reality to view and interact with those models. It's hard to explain just how it works, so here's a video, using one of the stock 3D models that come with the app:
See what I mean?
And as Bronwyn has very thoughtfully made her models available under a CC-BY-SA licence, anyone can download a copy of a file and use it within AndAR. So if you need to play around with an adze, a sperm whale tooth or even a giant land snail shell, now you can.

Four cool tools for studying astronomy

Two of my favourite applications when it comes to studying the stars are Celestia and Stellarium. The former allows one to fly through the solar system following planets, asteroids or satellites, while the latter allows one to place oneself anywhere in the world to watch the constellations travel across the sky above. Stellarium also allows one to pause, fast-forward or rewind time to see what the starts do. There are some very cool videos on youtube that showcase what these two programmes can do:

• Stellarium
• Celestia

There is also an increasing number of applications for Android that help people learn more about the night sky while standing in their front yard as well. Google Sky Map is great. If you want to find where Mars is, type in Mars and it will point an arrow in the right direction until you find it (video). Satellite AR is something I've only just discovered but it is no less impressive. It uses augmented reality to overlay the night sky with images and trajectories of satellites passing overhead. Here's a demo of it in action:

Wikitude AR

Okay, so here's something I've been playing with for a while: Wikitude AR. I first discovered it 18 months ago and have been working on integrating it with what we do at Albany Senior High School. It's augmented reality, which revolves around placing information into the landscape. The content is accessible with the use of a smartphone and mashes up GPS, 3G or wifi and a phone's compass. My history class had some fun placing information about the 1951 Waterfront Strike around the waterfront in Auckland. If you're interested in learning more, you can go there, and with the help of Wikitude AR learn as much as you like. Because the content is wiki-based and placed into the landscape, the only limit is a teacher's (or a class's) imagination. Here's a video of Wikitude AR being used around the Waitemata Harbour:
P.S. the bird you can hear calling in the video is the pukeko; a tenacious Aotearoa wading bird.

Open mobile learning

I'm totally convinced about a couple of things regarding mobile phones: that I can't be without mine for very long before suffering withdrawal symptoms, and they are going to be the main way we access learning within a few years. As a result I've decided I'm going to be blogging a bit more about mobile devices and their uses within schools as we explore their use more and more. Like most things I prefer free and open (and therefore lean toward Android as an OS) but I can see that the way we use m-learning in future will probably call on the strengths of Android, iOS (and possibly even Windows 7 for Phones). Stay tuned for more info about how ASHS is using mobile phones and tablets.
