Web Page Usability


jakob-nielsen
This guy has some great points about usability testing. Tesying is not something that crosses my mind on a daily basis, but he makes the point that
1. don't use your friends
2. anything that takes longer to load than 1 second is too long
3. you only need 5 users to test.

My Vampire Weekend


For this topic, I went to MP3.com and navigated over to the Free Mp3 page. I clicked on Vampire Weekend's infectiously groovy "Cape Cod Kawassa Kwassa" and listened to the streamed "Play Now" option and then downloaded the Mp3 Version onto my computer's hard drive and listened to each file, one after another using headphones.

Before I compared the files,
I needed a quick lesson about streaming audio and down loadable audio. Apparently there are there are two ways to deliver audio over the Internet . In downloads, the compressed file is stored on the user's computer and played using an installed software player like Windows Media Player, or iTunes. Mp3s are a very popular format, but AIFF, WAV and ACC can also be delivered through a web or FTP site. With streaming audio, the sounds are not stored, only played. This process is similar to analog radio signals, only sent through the series of tubes that is the Internet rather than the airwaves. The streamed audio is can be "On Demand" meaning that the file starts playing when the user clicks the "Play Now" button, OR listeners can "tune in" into live audio streams such as disk jockeys playing music, or speeches as they happen. These signals are picked up by applications embedded in the user'sInternet browser, or can be tuned in using Windows Media Browser or iTunes.
All this is interesting, but the core question is: How do they compare?

Mp3s: This format is much maligned by audiophiles as the end of listenable audio itself. It has been my experience that this is true to a certain extent. The terrible beauty of the MP3 is its small size, which makes it able to squeeze into ipods and through skinny Internet tubes. Compression ratio is the root cause at work. Audio sound waves are squished and flattened and chopped and channeled into a small size with only the most prominent frequencies surviving the process.

Streams: If audio lovers hate MP3s because of the loss of all but the most obvious parts of the waveform, you can imagine what they say about streamed audio. Not only are the sounds compressed like mad, but they are also subject to the vicissitudes of real time playback. The signal is chopped up into little "packets" and sent through the originator's server and through the listener'sInternet connection. When the tubes are full, packets get rerouted or forced to wait until bandwidth opens up. These Internet traffic snarls cause the dreaded buffering that interrupts playback.

The MP3 was passable audio quality. Sound quality was enhanced by the headphones and I was able to adjust my iTunes equalizer to goose up the lows by selecting the "Small Speakers" option.

The streamed option was limited by my sluggish connection and the lower quality/low bit-rate inherent in streamed audio formats. The highs exhibited the tinny, digital decay that is a hallmark of overly compressed sound-waves. The lows were dull and lacked the rounded sustain of natural sound waves.
So, in conclusion I would say that both formats are going to disappoint a few audio purists, but as an easy, portable Internet integrated listening option, both can't be beat.

What does E ink smell like?

Will we be the last generation to sit and leaf idly through the book in our lap? What about the smell? I used to be about to identify certain publishers by the way the book smelled when I opened it, probably something to do with the particular inks used in a particular print house. Will that sense be deprived as well as touch? I was wandering through the SONY mega store recently in San Francisco, a city of tech savvy, early adopters if ever there was one, when a bookish looking man materialized at my elbow. "Hi" he enthused, "do you want to see the new SONY eReader?" He pushed it into my hands. I looked, I saw a consumer electronic device that I want. The text seemed to levitate 1/8 inch off the surface of the Epaper it was displayed on. The screen itself didn't glow, it accepted the available light, like a printed thing. The man walkd me through the features, how to turn a page, what art looks like, how new titles are added... Which brings us to the first question I have about all eBooks:

1. How do you get the words in there?
I looked at 3 different portable books, the Kindle 2, the SONY Prs-700 and the iPhone. I realize that the iPhone is not technically an eReader. It doesn't have the fancy E Ink that sends little electrically charged capsules of pigment flopping and wallowing around like seals to form the letters of the alphabet, but it is small, it is wirelessly networkable and with the download of Stanza (http://www.lexcycle.com/) it allows you to read your stories anywhere. In a nutshell, The Kindle and the iphone uses 3G technology, like the smart phones that are constantly in communication through the wireless networks that transmit telephone calls. The SONY uses a connector, you have to have a computer to download the books onto SD cards, which the 700 accepts, or you can transfer the files via a USB cord. Mac users are out of luck, you have to use Windows to interact with Prs-700.

2. What is so special about eInk? It's an endlessly recycleable resource. The words are not back-lit like most other displays, so they take less energy to use. I've read a few descriptions about how it actually works and the best answer I can come up with is the tiny little capsule one in the paragraph above.

3. Will low-income serfs like me ever get a piece of the action?
Yes, I think that the price of an eReader is out of my range. the Kindle2 is $360, the prs-700 is $400 and the iPhone costs $200, not including service pack. A CD player cost $800 in 1985, now I can buy one for $12. The prices will come down just like any other consumer electronic. The question is, will publishers try to make their own proprietary readers that you can only use with their subscription? How will the print industry make selling eBooks and eMagazines profitable once the technology become ubiquitous?

In the future...we will still be reading books. Will they be bound collections of flat, dry cellulose based composite covered with solvent based deposits? Sure, just like there are radios in a world of digital televisions. Will libraries have row upon row of them? Yes. Will libraries have invested in the kind of technology that allows you to wirelessly connect to the library's main content server, or subcontracted, vendor provided file storage system and acquire everything on the New World Time's 2029's top ten list? Maybe. I'll be old and grumpy by then, perhaps I'll need my robot to read me the last book from Salman Rushdie's clone while my new corneas grow in. Well, that probably won't happen because it seems that a computer reading a digital book out loud is considered a "Performance" and subject to the collection of royalties, at least according to the president of the Author's Guild, Roy Blount Jr. This is a new twist in the age old problem of singular content, multiple formats. The Reuter's tech blog MediaFile quotes Blount as saying "... the technology Amazon uses to turn text into a human voice is quickly improving, and authors need to be 'duly vigilant' about this new means of transmitting their work."
Copyright issues aside, I am reminded of something digital librarian David Lee King (http://www.davidleeking.com/) said in an interview I taped with him recently. When asked about what will happen to books he said that a truly good book transports the reader out of their chair and puts them in the story as an unseen observer. The reader experiences the actions of the story in a way that transcends the words on the page and the container of the story itself. I believe that it really isn't about a book, but about the content.

SPECS: The latest entry to Sony's family of eBook readers, the PRS-700, includes a touch-screen and virtual keyboard Sony's PRS-700 is approximately 174.3 x 127.6 x 9.7 mm, weighs about 10 ounces, sports a 6-inch diagonal display with a 170 dpi/8-level grayscale resolution and contains 512 MB of memory. It uses a lithium-ion battery that allows 7,500 page turns per charge, and also has a built-in LED reading light. For Windows, Sony Reader contains Sony's proprietary Sony Connect (a.k.a. Sony eBook Library).
SPECS: Kindle 2 weighs in at 10.2 ounces, downloads books in less than a minute and sports a 25 percent longer battery life than the original Kindle. It allows users to peek at newspapers from around the world, download up to 230,000 books and also access blogs and 22 magazine titles. Storage is greater than the earlier Kindle, with 2 GB overall (enough for 1,500 books) and 1.4 GB available for user content. Display-wise, Kindle 2 offers 16 shades of grayscale and has a "Read-to-Me" function that offers text-to-speech
SPECS: The iPhone weighs about 5 ounces Screen size: 3.5 inches, Screen resolution: 320 by 480 at 160 ppi, Storage: 4GB or 8GB: ( 3000 to 6000 books) There were no specific details about battery usage for just reading, but the battery is said to last up to 5 hours for internet and phone usage. playback Dimensions: 4.5 x 2.4 x 0.46 inches. You will need to download eBook software such as Stanza or Shortcovers to access books online.

Mod Art 4 Mod Kids


This is a link to my latest Library School Project. We were tasked with making a Pathfinder consisting of mainly online resources about a certain subject that was suitable for Late Middle Schoolers. I started out with the idea that I would make a website for Contemporary Art, a subject that is near and dear to my heart. Sadly, there is not enough material about straight up Contemporary Art out there to merit 30 links, So I expanded out to include Modern as well.

I remember when I was an earnest 14 year old, I hated Modern Art. I thought it was stupid, and lazy and a pointless exercise in frivolity. Hmmmmmm, where do you think I got that atitude? My teachers! They scoffed and derided Modern Art concepts such as expressive line and color emotional relationships. I, in turn, applied myself to learning how to draw like a draughtsman, to painting like an uptight realist.

It wasn't until I went to college and started hearing teachers speak in loving terms about the way perceptions could be rendered in paint and pencil that I got a clue about how didacticism diminishes your life. Hopefully kids exposed to modern art and Modern Art concepts won't sound like the idiotic hillbilly I was when I first started talking about art.

Buffalo Bill, the comic


Hi, I've decided to post some of my assignment for class. Here is a comic I made using the excellent "Comic Life " software from plasq. I used old Wild West posters from the Library of Congress.
