3D Printers

I read this article about a 3D printer that was recently unveiled at the Consumer Electronics Show and couldn’t help but get a bit excited.  Sure, as the article points out, at $1300, this “affordable” printer may not be affordable for everyone.  (It’s not for me.)  But it’s getting closer to affordable.

The notion of being able to create or download a 3D image file on my computer, send it to the printer via a USB cable, and have the real object in my hand a few minutes (or a couple of hours) later is pretty amazing — and I’m not even in a business that does any rapid prototyping, nor do I have a burning need for my own custom designed neon ABS plastic chess set, two of the most often cited uses for such a device.

The best part will be watching the prices come down on these.  They are a bit expensive now, but in five years, I could see myself forking over $500 for something like this.  Especially if the media that is “printed” comes down in price as well.

I’m sure, in addition to being a fun, novel tool with which to experiment, I could find more and more uses for it once I had one.  Kids break one part of their favorite toy?  Make another!  This gadget were exactly the same but with a built-in loop for hanging it from a hook?  No problem!  Like something I have?  I’ll scan it and email it to you and you can print one for yourself (almost) instantly!  It’s a pretty exciting future.

Web Browsing in 3D

Everything else is available in 3D (movies, televisions, the real world), so why not 3D browsing?  I recently came across this demo video of a 3D browsing experience created using WebGL, HTML5, Javascript and the Mozilla Audio API.  Is this the future of Web browsing?

I’m not extremely fluent in all of these technologies (for more info, see Flight of the Navigator), but as a demo, this is pretty impressive.  To me, it looks a little like Second Life with tons of screens out to the internet.  In other words, slick and different, but I’m not sure how useful, or even how truly integrated this experience would be.  Would you rather navigate to different places on the Web by moving through a 3D space or by Ctrl-Tabbing to the next open tab in your browser?  Maybe I’m old-school, but the latter seems far easier to me.

Of course, there are lots of other demos posted online and it will be interesting to see where this goes.  Checking your favorite Twitter feeds in-game would certainly blur the line between the gaming experience and the real world, but is this necessary?  Probably not, but maybe that’s not the question to be asking with whiz-bang technology like this.  It certainly opens up interesting avenues for the greater integration of a wide range of technologies.  Where that takes us will be interesting to see.

Kinect Development

Microsoft recently announced plans to release a software development kit (SDK) for the Kinect.  This should allow academics and enthusiasts to find new ways to connect the motion-sensing Xbox hardware to other platforms, such as desktop and laptop computers, much more easily.  In short, there should be many more Kinect hacks to come.

I’m still not sure how this would directly apply to classroom teaching, although it stands to reason that these applications could someday replace physical interactive whiteboards in the same way that Kinect was originally designed to replace physical videogame controllers for the Xbox.

For more, see my previous post on Kinect Hacks and below for some new examples of how Kinect is being used in new and exciting ways.

Control Windows 7

The touchless multitouch is really nice.  Mice are so 2008.

3D Tetris with Face Tracking

As the user moves his head, the perspective on the screen changes to match so that the 3D perspective is constantly updated.

Kinect Lightsaber

A wooden stick becomes a lightsaber in real time.  This would save hours of  frame-by-frame editing.

Balloon Body

After Kinect scans your body, use your scroll wheel to expand or contract the surface.

Christmas Lights

Use Kinect attached to a bunch of dimmers to control Christmas lights for a very nice effect.

Flying Robot

The 3D capability of connect makes it perfect for a robot that navigates three-dimensional space.

2010 in review

I got this auto-generated post direct from WordPress, which hosts ESL Technology.com, and thought some of it was worth sharing.  Every time I login to my blog, I can check on these numbers and other interesting data.  I can see how many page views I’ve had by day, week, and month as well as which pages were most popular and what sites are referring people to my blog.  More interesting than the numbers themselves are the fact that this data is so easily available that WordPress can automagically pull it together into a blog post for me.  (Incidentally, you can search “2010 in review” on WordPress to find other bloggers who have posted the autogenerated post.)

This kind of data is becoming easier and easier to work with — to mashup.  And all kinds of new software allows us to pull together lots of data in enlightening ways.  Governments that are making this kind of data available are finding citizens stepping forward to develop ways to make it more useful.  See Tim Berners-Lee’s TED Talk for a six-minute rundown of the highlights, below.

I recognize that the numbers generated for me by my blog are not as important as which roads are impassable after an earthquake in Haiti.  But, on almost every scale, this data is becoming easier to find, use, and mashup.  Some of our students may already be doing this.  Surely, many are not.  Developing the ability to work with this kind of data in very dynamic ways is sure to be an asset, if not an expectation, in the near future.

So, without further ado, my numbers.  Thanks for reading.

A Boeing 747-400 passenger jet can hold 416 passengers. This blog was viewed about 13,000 times in 2010. That’s about 31 full 747s.

In 2010, there were 50 new posts, growing the total archive of this blog to 119 posts.

The busiest day of the year was August 4th with 95 views. The most popular post that day was OutSMARTed.

Where did they come from?

The top referring sites in 2010 were twitter.com, esl.osu.edu, en.wordpress.com, en.bab.la, and google.com.

Some visitors came searching, mostly for esl technology, esl and technology, technology esl, technology for esl students, and kinesthetic learners.

Hacking Kinect

I never really thought much about Microsoft’s Kinect until I saw what hackers were doing with it.  A story in the New York Times outlines how a designer and senior editor at Make magazine posted a $3000 bounty for the first person to post an open-source hack of the Kinect interface.  Huzzah!  In fact, I’m still not that impressed with it — 3D drawings are cool, but will they help me teach English? — but I’m thrilled that hackers big and small are poking around under the hood.

Interestingly, Johnny Chung Lee, who became famous for his TED talk where he described hacking a Wiimote to act like an interactive whiteboard, is involved in the development of Kinect.  Microsoft were so impressed with his skills on the Wii-based IWB and other projects they hired him.  He is reportedly very happy to see hackers taking on Kinect in the way he took on Wii a couple of years ago.  If a hacker can squeeze an interactive whiteboard out of a $40 Wiimote, what will come out of the $150 Kinect system?

Will this technology help us teach ESL and EFL?  It’s not easy to see how, at least not immediately.  But prepare for a giant step forward in how we interface with computers in the next few years.  Interactive whiteboards are just the beginning.  You can always show your students this video and ask them to predict the future (in English).

Interface with the Future

I’ve been thinking about interfaces for a while. Interactive whiteboards (IWBs) probably got be thinking in this direction, and the recent announcement of the motion sensing Project Natal for the Xbox has finally pushed me to write about them.

Note the fine print: actual features and function may vary.

As computers have evolved, so have the interfaces we use to interact with them.  To give you an idea of my own personal timeline, I have no experience programming on punchcards, but I do remember the pre-GUI days.  The mouse has become ubiquitous, but what comes next?  Here are some possible answers:

Interactive Whiteboards: These are pretty heavily documented on this blog and elsewhere.  Here, the user can interact with the display, making the mouse and, to an extent, the keyboard unnecessary.

Slap widgets: Physical tools to be used with IWBs and the like, further blurring the line between the physical and the virtual.  (Watch the video!)

Siftables: An interesting miniaturization of an IWB-type interface with the added bonus that each mini screen can interact with the others.  If each Siftable had a letter or a word, how could they be used to teach English?

MIT’s Sixth Sense: This video went viral a few months ago, but keeps popping up.  Why can’t your computer interface with the physical world?  It soon may.

Wii & Natal: Nintendo has enjoyed blockbuster sales of it’s Wii gaming system which features motion-sensitive controllers.  Now, Microsoft has unveiled the same thing with Natal, but no controllers are needed.

Do it yourself interfaces: In addition to making your own IWB using a Wiimote, other examples include the Beatbearing, in which ball-bearings are used to sequence electronic drum beats, a modified Nintendo Powerglove, which upgrades late 1980s virtual reality technology, and a giant Katamari ball controller, which is a controller designed and built specifically for the game Katamari, in which players roll a ball through an environment which attracts more stuff (litter, park benches, people, their pets, etc.).  The makers of each of these interfaces have posted detailed plans and instructions online so that you can build and modify your own.

Move over visual learners, kinesthetic learners are about to have their day.  And why not?  Why should  simply watch something when we can interact with it in more natural ways?  The next generation of computer interfaces promises to expand our idea of how we relate to computers.
