Geek on the Cheap #132:
iPad versus Skinput — Device versus Surface

Sunday, April 4th, 2010

No, this is not yet another review of the vaunted iPad. Yes, I did swing by the local Apple store on Saturday to check it out: it looked/worked like my iPod Touch ballooned a few times larger, with lots more fingerprints. Enough said. (If you want an iPad review, you can read a ridiculous number of iPad stories from Wired.com or just go and play with an iPad yourself.)

What you may not have heard due to all the Apple mania, is that the JooJoo tablet also came out this past weekend. Originally dubbed the CrunchPad, it’s had a tortuous journey to market and looks a little like the iPad’s ugly stepsister (see also Engadget’s unboxing video).

Soon there will be more and more tablets to choose from, just as there are now a plenitude of netbooks on the market. So the question is: Which is the future — tablet or netbook? Or neither?

Both tablets and netbooks are taking two user issues into consideration: size and functionality. Ideally, we users would like all the functionality of our desktop or laptop computers in a smaller (more portable) form factor. Or, we want at least the functionality of our smart phones in a larger form factor. The netbook partially solves the first issue and the tablet partially solves the second. There’s also the creator vs. consumer issue. The netbook makes it easier to be a creator with a built-in keyboard and access to productivity software. The tablet makes it easier to be a consumer with a simple touch interface and ready access to entertainment and social networking.

Of the two, the tablet has captured the imagination in a more concrete way. According to Wired, the tablet “will change the world.” (A mini-entertainment center is a lot more fun than a mini-workhorse.)

But in fact we kind of want it all, don’t we? We want small size (phone size) and high functionality (desktop functionality). We want to be able to create at times and consume at times. But how many devices do we want to purchase and carry around and have to sync? Instead of more devices, what about one small device and many surfaces?

This is where something like Skinput comes in. It projects an graphical user interface (GUI) on your arm, then reads the vibration when you tap your arm. The example they show in the video of controlling another device strapped to your arm is where you can see its utility. It wouldn’t work for typing, for example, because you’d be one-handed. But imagine being able to project a GUI or a keyboard wherever you want — like the Virtual Laser Keyboard (VKB), only smaller, more accurate, more graphically extensible.

Now imagine a tiny device in your pocket that transmits to a tiny projector that you can use for input and output, or to a “screening” surface that you can fold up and stick in your pocket. Now that’s the future. The tablet is merely the right now.

Scanning a Book in One Minute – Process vs Product

Sunday, March 28th, 2010

How could it be possible to scan an entire book in one minute? By flipping the pages, of course. Researchers Takashi Nakashima and Yoshihiro Watanabe at the University of Tokyo have developed a superfast scanner that lets you digitize a book by rapidly flipping pages.

Their system uses a camera with an incredibly fast shutter (500 frames per second) to take pictures of the text and/or images as the pages are flipped. Except, you might interject, what about the fact that the pages are curved as they’re being photographed (we’re flipping the pages, right?). You’re right! Because the pages are curved, the letters in the text and any images will be distorted in the pictures taken. They would be useless if the clever researchers hadn’t solved this problem by shining a laser on each page that projects a set of lines, which are also photographed. Their software then uses the lines to flatten each image.

(FYI, for those of you who don’t know, converting an image of text [not readable by a Kindle or Nook, for example] into a PDF [a format recognized by text readers] is already quite easy and accessible to all by using OCR software.)

The next step the researchers plan to take is miniaturizing the process for integration into smart phones. “One day,” according to Erico Guizzo, “you might be able to flip the pages of a book in front of your iPhone and get a digitized version in seconds.”

Holy crap! When the news story about the superfast scanner came out on March 17th, I imagine thousands of publishers took this epithet literally as they dropped to their knees to pray it ain’t so.

On the other hand, let’s look at the process for a minute and not just the product. The device is predicated on the existence of a hard copy book, not a digital book. And it’s predicated on the idea that you want to read this hard copy book in digital form. One scenario would be that don’t want to buy the digital form. So you go into a bookstore, pick up a book and scan it — essentially stealing it. Makes the whole idea of getting a digital copy for free hit home, doesn’t it? It really is stealing.

The truth is that it’s not going to get harder to convert books to digital form or to share them in digital form. It’s only going to get easier. So the only thing that will stop the theft of intellectual property is the knowledge, the true sense, that it is theft if you don’t compensate an artist for his or her work. I’m not being all high and mighty here; I’m as guilty as the next person of having downloaded one or two things for free. So I’m saying this to myself as well as everyone else. Not compensating artists is simply not right.

But there is yet another side to this issue: What if you want to digitize the books you have paid for? The ones sitting upon shelf after shelf at home? Daniel Reetz, founder and steward of the DIY Book Scanner community, built his own book scanner for about $300 because he wants his books with him everywhere. (I can relate to this; when I travel, I always overpack books.)

If you’d like to build your own book scanner, his instructions are available at “DIY High-Speed Book Scanner from Trash and Cheap Cameras” or DIYBOOKSCANNER.ORG. (Yet another project to add to my list.) Of course, scanning a book with this DIY device will take a lot longer than a minute, but that just gives you time to fondle your book. Oops, should I not have divulged that?

Connect Your Laptop to Your TV + Howcast + SXSW

Sunday, March 21st, 2010

The title says it all this week (see the video). But there’s more behind these handy intrux if you’re a budding filmmaker.

First off, last week was SXSW, a major networking event for the music industry but more interestingly, from my point of view, it’s also now an “interactive” festival geared toward web developers, bloggers, new media entrepreneurs and more. (See my Twitter feed for a couple of nice links to wrap-ups.)

At the same time, I was looking around this week for a GoC topic and found Howcast, a website that’s like Instructables in that it provides how-to’s (such as the one above), and different in that it’s the #1 global mobile platform for instructional video and develops filmmakers by having them create said videos.

My favorite topic area is Technology, of course, but there’s a wide selection ranging from How to Not Suck at Socializing to Baby Sign Language to Finding a Green Hotel.

Interestingly, about a month ago Howcast announced that it was expanding its Emerging Filmmakers Program (EFP), “offering filmmakers a tiered program that will allow them to get more involved with more challenging — and rewarding — video-making.” EFP provides their filmmakers with a fully researched script, professional voice-overs and embedded graphics, then gives them feedback on every upload thus allowing them to refine their skills. Pretty cool for those of you out there who are looking not only to improve your work but to get more eyeballs on it.

How does this all connect?

Well, if you’re an emerging filmmaker, you can get tips on how to attend SXSW from Heather Menicucci of Howcast. Meanwhile, you can work on your skills by making videos for Howcast (you have a year, after all, until the next SXSW). Then you can connect your laptop to your TV to look at your work and show it to others. Beautiful!

Or, you can simply hook up your laptop and watch a few videos on Hulu. The instructions are clear and easy to follow. In my opinion, the factory (the filmmaker) did a good job. What do you think?

Need a Theme Song for Your Website? Enter Codeorgan

Sunday, March 14th, 2010

codeorgan

I’m lucky enough to have a husband who plays guitar and writes songs occasionally, one of which I have appropriated as my theme song. But that’s my personal theme song. What about 2literal.com — my public face?

This week I heard about Codeorgan on GeekBrief.TV (#720). Codeorgan is a free service that translates the code behind your website into music.

It looks at the content in between your homepage’s “body” tags, scraps any characters not found in the musical scale (A to G), then looks at these characters to determine which is the most commonly used “note.” If there are an even number of these notes, then the song will be in a major pentatonic scale; if it’s an odd number then the song will be in a minor scale.

It also defines a synthesizer to use based on the total number of characters used on the webpage, and a drum loop based on the ratio of that total to the number of characters that are musical notes.

The upshot is a pretty decent song. Listen to 2literal.com (it takes a few seconds to process). Not bad, right? Now I need a motto.

Albert Einstein said, “Imagination is more important than knowledge.” According to Helen Keller, “Life is either a daring adventure or nothing.” A dramatic sentiment for a dramatic life. But I think I like designer Phillip Lim’s motto — “Some days peanuts; some days shell.” Today I give you peanuts.
