Mobile and Web are the key point in teaching computer graphics

This year I have experienced a really difference in my Computer Graphics course. I'm still using processing in my laboratory work, but I have introduced a new unit called 'From Desktop to Mobile and Web'. You can check it out, with my all slides and materials of the course, at http://processing.tk

Any difference from my previous courses ? Many. Students were really more motivated and I have received a brilliant collection of good little projects: games, augmented reality examples, image viewers and so on. Why were my students so motivated ? Because they were able to port their processing application to Android and the Web, using android.processing.org and processing.js.

World is changing, and mobile devices (smartphones and tablets) are going to be the items everybody will desire and buy this year. It is really interesting to offer our students the opportunity of working with these new hardware, and processing allows it. We can make the most of their sensors (accelerometers, magnetometers, camera etc.) when creating a game or app.

Why Mobile Augmented Reality doesn't work

I came back yesterday from Sweden. There, I was in an international conference where I had a work to present.

Being a Nexus One owner, I was very excited before the trip. Applications like Layar and Wikitude would be helping me a lot there, in Stockholm. I didn't know anything about the city, so this Augmented Reality (AR) apps could have been helpful, but it didn't.

Why ?

Are not those AR applications useful ? Yes, they are. But in order to use them, as well as Google Maps, Navigator and Googles, you need internet connection. And here it is when my problems arise.

Enjoying here, Spain, a 3G data connection, I asked about prices in Sweden. They're cheap as far as you have a swedish telephone company, but coming from abroad the things are really different. How much different ? 10 euros / 1 Mb. Yes, it's not a joke.

And that's not something between Spain and Sweden, it seems it is a common problem when traveling in Europe. Fantastic.

So Google and others are providing fantastic solutions and we cannot use them when we're in the perfect situation to use them: when we're abroad.

Thanks we're in a European Community !!! Just enjoy the following picture you can see at Layar website. See the world ! ... if you don't mind to pay a lot for it ;)

New ways of reading books

Following my previous post, here another example on how iPad and the new tablet devices are going to change the way we read, learn and interact with books and magazines:

Multitouch devices and education

We have been discussing a lot about the possibilities of multitouch interfaces, speculating about their real advantages over traditional interaction paradigms.

But now, with the current explosion of the iPad and a huge assortment of new multitouch tablet devices to come, we have now real and fully functional applications.

The example of the following video is really very representative. It's really a good example on how these new devices, multitouch enabled, with the new refreshing way of approaching to user interfaces, can undoubtely change fields such as education, magazines, books etc.

AR at SkyNews

A very interesting AR demo from Total Immersion at SkyNews. Visit this specialised AR French company website for additional online demos and videos.

Without any doubt, Augmented Reality is becoming more and more popular.

Do you want to learn processing ?

Very nice set of 5 tutorials with which you can follow an introduction to processing.
In the last one, a final little demo is generated using input audio and displaying the different band levels in an interesting fading effect.

Created by switchboard (Andy Best).

Yes, it's still a prototype, but ...

In the following video from a company called TAT, you can see a prototype of an AR mobile solution of theirs really fantastic. It is a prototype but it looks potentially very interesting.

The problem is legal issues and private rights. What do you think ?

Augmented Reality in one hour

I have discovered a very interesting video describing AR technology in about one hour, focusing on mobile solutions. It is part of the youtube O'Reilly channel. Although it is difficult nowadays to have one hour free, and the sound is very bad, it is really worth watching it.

Another video about the future of AR

Another nice video about the future of Augmented Reality (AR). We're talking about AR a lot lately, thanks to the fact that we are enjoying real applications (iPhone and Android phones, e.g.)

I wonder when we will be able to have those glasses.

The continuous evolution of processing

From the very beginning, processing was created as a development platform with one objective in mind: generative/procedural art. And this objective is a reality not only because of the tools this language offers, but because some additional libraries some developers are providing to this open community.

People from toxiclibs and their incredible set of libraries for processing is an example.

In the following video you can see a showreel of some of the works created using processing and toxiclibs libraries:
