State of the Art
Brilliant Ideas That Found a Welcome
By
DAVID POGUE
Published: December 28, 2006



It may take a village to raise a child, but that’s a trivial task compared with the act of bringing a new electronic gadget to market.


lllustration by Stuart Goldenberg


Marketers determine what the masses want, product managers guide the design, engineers bring the thing to life — it’s a lot of cooks. No wonder so many people across the country are, at this very moment, staring at newly unwrapped electronic holiday gifts in utter bewilderment.
Even so, brilliant ideas sometimes make it off the drawing board, past the layers of lawyers and onto store shelves. Sometimes, a delicious idea is part of a triumphant overall product. Other times, the flash of greatness is wasted on a turkey.
Here, then, is my second annual Top 10 List — not of the greatest tech products of the year, but of the greatest ideas, individual features, that surfaced. It’s a little tip o’ the egg nog to the great thinkers whose ideas made it out of committee.


THE FLASH-DRIVE FUEL GAUGE You gotta love those U.S.B. flash drives. They’re cheap, shiny and tiny, and they offer a practically perfect way to transport computer files.
On the other hand, you gotta hate it when you plug in a flash drive to receive a file you need — and discover that the darned thing doesn’t have enough free space.
That’s the beauty of ,
Lexar’s Mercury flash drive, whose case has a “fuel gauge” — a bar graph that tells you, without even plugging the thing in, how full it is. Thanks to a technology called E-Ink, this graph is always on and stays visible indefinitely, without requiring any power whatsoever.

THE MAGNETIC POWER CORD Somewhere there’s surely a support group for people who have dragged their $2,000 laptops to the floor by tripping on the power cord.
That doesn’t happen with
Apple’s 2006 laptops, whose power cords connect with a powerful magnet rather than a pin or a plug. If someone trips or yanks on the cord, the magnet detaches and drops harmlessly to the floor. The laptop switches seamlessly to battery power, saving your data, your money and months of therapy.
Better yet, this magnet has no “right side up”; it works no matter which way you slap it on. Oh, and it lights up to confirm that you’re plugged into a working outlet.

THE TWO-STAGE FLASH It may seem counterintuitive that the more expensive the digital camera, the less likely it is to have a built-in flash. The manufacturers assume that if you’re that much of a professional, you certainly own an external flash unit.
Among other virtues, an external flash can be aimed upward so the light bounces off the ceiling, rather than blasting into your subject’s face. The result is more even and flattering light.
Panasonic’s Lumix DMC-L1 and LC1 cameras, though, offer the best of both worlds. If you push the open button for the built-in flash firmly, it pops up and faces forward.
But if you push lightly, it pops up to a different position, angled 45 degrees upward — yes, in bounce-off-the-ceiling position. Great idea, cleverly done.

A RECORD RADIO BUTTON Samsung Helix is a regular music player, like an
iPod (though smaller). But it’s also an XM satellite radio receiver.
That’s already a good idea, but here’s the clincher: When you hear a song that you like on one of XM’s 70 themed, ad-free music channels, one button-press records that song from the beginning — even if you were a little late hitting record. In all, this gadget can hold about 25 hours’ worth of recorded radio.
Long-suffering music fans could probably have predicted that XM would be sued over this glorious idea, and, well, sure enough. Maybe what’s so great about this idea isn’t so much its ingenuity as its bravery.

MUSIC BEAMING The Zune,
Microsoft’s new music player, does something amazingly well that its rival, the iPod, doesn’t do at all: It lets you beam songs or photos wirelessly to another Zune. It’s easy and fast, and it could be a great way to discover new music recommended by your friends.
In practice, there’s more to the story. To avoid lynch mobs from the record companies, Microsoft designed the Zune so that beamed songs self-destruct after three plays or three days, whichever comes first — even, idiotically, your own recordings like college lectures and garage-band demos.
The Zune, therefore, is that classic case: a killer idea diluted by a ham-handed execution.

THE VIDEO-GAME WORKOUT
Nintendo’s Wii game console, on the other hand, is a stellar product that succeeds precisely because its central idea is unencumbered by corporate baggage — and is tons of fun.
The masterstroke is its wireless controller, which detects the motion of your arm in three dimensions and in real time. As you swing, jab or whap through the air, your animated character on the TV screen swings the corresponding baseball bat, tennis racquet, fishing rod and so on.
(Perhaps it’s a bit much to suggest that this video game may actually help to address America’s problem of sedentary youth. But my own two in elementary school play the Wii’s tennis doubles game nightly with full-body vigor — and are perspiring after half an hour.)

THE TRACKPEARL On most
BlackBerry cellphones, you scroll through on-screen choices using a side-mounted thumb wheel. Too bad if you’re a lefty or if you’re trying to move horizontally across the screen.
The tiny and terrific BlackBerry Pearl solves both problems neatly: it has a front-mounted trackball. This ball is also clickable, so you can scroll to something and then select it with a single quick thumb flick.
And because this trackball is pearly white, translucent and illuminated, it nests neatly with the phone’s name and concept. A pearl, indeed.

THE FACE FINDER Several 2006 Canon cameras, including the image-stabilized SD800IS, offer face-recognition software. In this mode, the camera identifies human features in a scene, even in group photos. Little rectangles appear around each face (up to nine in a scene) as you view the back-panel screen; these little rectangles move around, tracking your subjects as they shift.
The point of all this is to calculate focus and exposure properly for portraits. The facial recognition eliminates shots in which, for example, the camera locked its focus on something in the background. And it forces the flash to throttle way back to avoid blasting nearby faces into whiteness.

POINT WITHOUT POINTING The speech-recognition software in Windows Vista offers anyone who can’t type — or doesn’t like to — a slick, efficient alternative. Wearing a headset, you can dictate text into any program and “click” any button or tab by saying its name.
But what if you don’t know its name? What if it’s some cryptic little toolbar icon? You can’t exactly say, “Click the little thing that looks like a watermelon seed on two beach balls.”
What you can say, though, is “show numbers.” The program immediately overlays every clickable thing on the screen with colorful numbers. You can just say “21” (or whatever) to click the corresponding spot — a trick that works especially well for navigating Web pages.

THE UNCOMPLICATED CELLPHONE Plenty of people have, while grousing to their spouses, imagined a cellphone that does nothing but make phone calls — no Internet, camera, music, text messaging, or any other complicated gimmickry. In other words, it’s not such a new idea.
GreatCall, however, has actually gone and built one. Its Jitterbug phone is a big finger-friendly flip phone with huge light-up number buttons, no nested menus at all, and — get this — a simulated dial tone.
Any big-name cell carrier can beat this phone on price, network coverage and, of course, features. But for the aging technophobe, this one’s an idea that works.

A SPARKLING YEAR The truth is, you could fill 20 more columns with all the good ideas that popped up this year. For now, though, here’s a toast to the dreamers who thought up these delicious twists — and the committees that let them through.

A net phone called the iPhone has been launched by Linksys just weeks before analysts were expecting Apple to release a similarly-named device.

The wireless iPhone allows users to make free or low-cost internet phone calls using the Skype service.It joins a growing market of phones which use wi-fi to make telephone calls instead of traditional mobile networks. There has been intense speculation about Apple entering the mobile market for the last few months. Wireless net telephones are growing in popularity because they offer a low-cost alternative to making mobile phone calls. The phones can connect to wi-fi networks - which are often free or low-cost to access - and access the net to make telephone calls, using Voice over Internet Protocol (Voip).
Analysts predict
Increasingly, mobile phone manufacturers and operators are incorporating Voip services into handsets. Apple has neither confirmed or denied that it is working on a mobile phone but speculation has continued for months with many analysts predicting it will be unveiled in January in San Francisco. Jupiter Research analyst Michael Gartenberg said the speculation around the Apple product - which was expected to be called iPhone - showed there was "pent up demand for something from Apple". Many analysts predict that Apple will launch a device which combines the features of a mobile phone with its popular iPod. But there is uncertainty over whether the device will simply be a Voip handset or will also connect to mobile networks. Jupiter analyst Thomas Husson, told the BBC News website, that he did not expect any Apple phone, if one were launched, to have an immediate impact on the mobile market.
'Disruptive'
"It's a very competitive market. It will take time for Apple to be disruptive." He said that any Apple phone would most likely be sold direct to consumers, rather than through a mobile operator. That would mean customers would have to pay a premium for the phone, as it would not then be subsidised. "Apple would need to offer a compelling phone experience," he said. The Linksys iPhone comes in two models - a $180 (£92) model which can make Skype phone calls and a $200 (£102) model which is a dual Skype and landline phone.

Everybody's Talking About RSS

By Merle
February, 25 2004


No matter if you call it "Really Simple Syndication" or "Rich Site Summary," RSS is definitely all the rage right now online. With email filtering, IP blocking and the newest "Can Spam Act," everyone's scampering for a better way to get their messages across to their subscribers.

With RSS, the customers don't have to come to your website or open their inboxes to get your latest news and updates. Once they subscribe to your "feed," the news comes to them automatically. But wait; I'm getting ahead of myself here. Let's get back to the basics.

RSS is an XML based format that originated with Netscape. To use RSS, you must first create what's called a "feed." This is basically a file which you upload to your server. RSS feeds end with .rss rdf or .xml extensions and can be created by hand. An RSS file needs to include the headlines, links, and summaries of the content you want to distribute.

Once a feed has been created, other computers can subscribe to your "channel" and read your updates using what's called an "Aggregator" or "news reader."

Most feeds consist of a link with a short summary to click on to read the entire article. To let people know your site offers an RSS feed, you place an orange XML icon on your site linked to the url of your feed. You'll also want to list your feed with various RSS search engines that exist just for the purpose of collecting a database of feeds.

So what kinds of things can you turn into feeds? I thought you'd never ask. Any area of your site that changes on a regular basis is a good candidate. Things like newsletters, news announcements, site updates, anything that you update regularly.

How to create a feed?

If you have no idea how to create a feed, this site will do it for you: MyRSS.com .

Just type in the HTML page you wish to make a feed from and it converts it to RSS for you automatically.

Another great tool that will create a RSS feed for you is Feedster.com . This works especially well if you need a feed of your third party hosted Blog, for example Blogger.

There's also a script that will convert any HTML doc into RSS -- Go to http://kalsey.com/tools/blogfeed/ . If you'd like to validate your feed, you can do so at FeedValidator.org .

A News Reader is simply a software program that brings what's new straight to you in an organized, easy to read format.

Let's take a look at some of your options when it comes to readers and what's available to you.

1) RSSReader: Free; it collects news in the background and warns you with a popup in your system tray when there's new information available.

2) Ampheta Desk: Free, cross platform aggregator.

3) WildGrape: For Windows; reads headlines from thousands of sources. Free.

4) Sharp Reader: Free reader for the .Net Framework created by Luke Hutteman

5) Newz Crawler: Web News Reader and browser. There's a two week free trial. You can purchase it for only $24.95.

6) Feed Demon: Download a free trial or purchase for only $29. Written by Nick Bradbury, creator of Top Style and Hoesite. Feed Demon is loaded with great features.

7) Feed Reader: Freeware; Windows app that supports all RSS feeds and formats.

8) Blog Lines: A web based Blog and newsfeed reader. No software to install to read your feeds; just visit the site and log into your account.

9) Awasu: Free Windows news reader that integrates with Internet Explorer.

10) Feed Readers: Lockergnome's offering in the news reader field. Seven day free trial. Two versions available: pro or standard with pricing ranging from $5.00 to $15.00.

If these options aren't enough, you'll want to check out the full list of readers over at
http://www.lights.com/weblogs/rss.html

If you'd like to have feeds sent directly to your inbox instead of downloading a reader, check out BlogStreet.com

Once you download a reader you need feeds to subscribe to. Check out Syndic8.com for thousands of choices.

So now that you understand the technology, what are the advantages and disadvantages of RSS? Here's a big one: your subscribers don't have to give up their email addresses, which is great for those with privacy concerns. RSS puts control of subscriptions directly in the hands of your users. When they wish to unsub- scribe they just delete the feed from their reader. It also reduces the risk of Spam accusations. If you're an ezine publisher and you don't have to worry about getting your messages past all of the filters in place by users and ISP's.

The disadvantages are that you cannot include personalization, and you have no way of knowing how many people are subscribing to your feed. Also, at this time, RSS may seem a bit complicated to the novice user and it has not become widely adopted by Web users.

If you haven't looked into RSS, now's the time to consider this technology as another avenue for reaching out to your website visitors, and keeping them informed.

Delta Asesores

Errores en Diseño Web 2003 (I & II)


Jacob Nielsen es un reconocido experto en usabilidad y arquitectura de sitios Web, y a finales de diciembre publicó el resultado de su análisis de los 10 errores garrafales en los que incurrieron los diseñadores durante el 2003. Este análisis es el cuarto que efectúa, habiendo elaborado los tres primeros en 1997, 1999 y 2002. A continuación iniciamos la divulgación y el comentario de estos errores para el 2003 con algunas recomendaciones para resolverlos en su propio sitio.

1. Propósito poco claro

Muchas empresas, y en particular en la industria de alta tecnología, se utilizan lenguaje vago o genérico para describir su propósito. Es difícil para los usuarios entender exactamente qué pueden encontrar en el sitio cuando su descripción es así de vaga.

Un modelo mental fuerte se compone de pequeñas semillas, a medida que cada elemento de diseño le agrega a lo que el usuario ya entiende del sitio. Sin embargo, muchos sitios crean un modelo mental borroso en la mente de los visitantes porque no ofrecen una visión clara con la cual los usuarios puedan entender el contexto de los elementos.

2. Nuevas direcciones para contenido almacenado

Los archivos agregan valor substancial a un sitio, sin incurrir en mucho trabajo adicional. Aunque cada vez son mas los sitios que están archivando contenido anterior, la mayoría de ellos fallan al construir el archivo. Algunos sitios tratan los archivos com un sitio independiente, asignando nuevas direcciones a las viejas páginas cuando las mueven de la sección principal al archivo.

El cambio en la dirección ocasiona enlaces rotos. También hace que otros sitios no tengan interés en ligar al suyo ya que tendrían que actualizar el enlace cada vez que se cambia la dirección de su contenido.

3. Contenido sin fechas

Sin fechas en artículos, boletines de prensa y otro contenido, los usuarios no tienen idea si la información es actual u obsoleta. Muchas de las cosas que se escriben en un sitio dependen de las fechas. Un artículo puede ser irrelevante sin su fecha, pero con ella, así sea viejo el artículo, puede servir de referencia para como eran las cosas en aquél entonces.

Algunos buscadores presentan las fechas de los archivos al pié del resultado, sin embargo la fecha es de cuando este archivo fue incorporado al sitio Web y no necesariamente cuando se escribió. En el cambio de alojamiento del sitio de DELTA Asesores la fecha de TODAS las páginas quedó asignada a finales de diciembre pasado, lo que hace irrelevante esta fecha al mostrar los resultados del buscador. Esto implica un cambio adicional que habrá que hacerle al buscador para que no presente la fecha del archivo!

4. Pequeñas imágenes de fotos grandes y detalladas

Los sitios han madurado en el uso de imágenes, haciéndolas más livianas y más pequeñas y así evitando las largas esperas en su descarga. También se ha popularizado la inclusión de imágenes más pequeñas (thumbnails) con un enlace a una imagen más grande para poder ver mas detalle.

El mayor problema es que se producen las imágenes pequeñas mediante el escalamiento de imágenes grandes. Es difícil que el detalle de una foto grande se pueda distinguir en una pequeña, y casi hace imposible ver nada en la imagen pequeña. Se recomienda hacer un "resaltado relevante" mediante un recorte de una porción de la gráfica que se enfoque en un elemento sobresaliente de la foto.

5. Mucho de talle en el texto para ALT

Muchos sitios han empezado a ponerle cuidado y a seguir los lineamientos para los usuarios discapacitados, como la inclusión de texto en la variable ALT para las imágenes. Sin embargo, este texto con frecuencia es excesivo y trata de describir la imagen. La recomendación es que en el ALT se describa lo que el visitante necesita saber de la imagen para tomar acción en el portal, no para "adivinar" como es la imagen.

6. No hay soporte de "que pasa sí"

Para una buena parte de las actividades en una web se requiere la posibilidad de seleccionar entre varias alternativas, aunque muchos sitios no la proveen. Por ejemplo, ¿qué pasa si quiero viajar el viernes en vez del sábado? Para responder a esta pregunta, en la mayoría de los sitios habría que llenar de nuevo la información de un nuevo viaje. Aunque algunos sitios permiten seleccionar unos productos y luego se produce una tabla comparativa, estas tablas tienen poca utilidad ya que no resaltan las diferencias.

Es indispensable que los sitios permitan al visitante cambiar uno o varios de los atributos de lo que está buscando, de tal manera que los demás componentes permanezcan fijos, y se obtenga el valor resultante de los cambios. Un buen ejemplo de esto es el sistema de pedido en línea de Dell que permite al usuario agregar y/o eliminar características de los equipos que se están configurando sin tener que iniciar de cero.

7. Filtros a los atributos

Anteriormente un sitio ofrecía tres o cuatro cosas. Ahora ofrecen tantas cosas que puede ascender a los miles y/o millones. Uno de los lineamientos de facilidad de uso en las páginas de categorías es permitirle al usuario excluir items que no correspondan a un criterio en particular, dejando como resultado una lista de menor tamaño y más manejable. Se debe entonces efectuar desarrollos de estos árboles en los sitios ojalá en bases de datos que permitan la búsqueda por cualquiera de los criterios, tanto en forma incluyente como excluyente. Por ejemplo, debería uno poder entrar a un portal de zapatos y pedir que solo muestre los que están disponibles en talla 41 color negro. Si no hay existencia, no debería mostrar nada.

8. Productos clasificados solo por marca

La mayoría de sitios que ofrece productos de diferentes marcas solo permite la clasificación por marca, pero no por colores por ejemplo. Tendríamos toda la ropa de un proveedor en particular clasificado por el proveedor, pero no los colores, que tal vez sería el criterio que el usuario valoraría. Se convierte en asunto importante entonces determinar cuales son los atributos que valora el usuario, y aunque las respuestas son distintas por categoría de productos, una investigación corta con usuarios, o con vendedores de los productos, podría arrojar estos criterios.

9. Restricciones en formularios

Por alguna razón los sitios web están colocando el trabajo al visitante, en vez de a la máquina. Por ejemplo, en formularios de registro, separan la información del Nombre y del Apellido, en vez de dejar un solo cajón para los dos. Lo mismo sucede para números telefónicos donde separan en cantidades de dígitos, o en números de tarjetas de crédito. Los esquemas de validación también entorpecen esta labor. Si un usuario se siente más cómodo ingresando la información de su tarjeta de crédito con espacios cada cuatro dígitos (como está físicamente en su tarjeta), debería poderlo hacer y luego el sistema los uniría.

10. Páginas que enlazan a sí mismas

Tener un enlace a la página de inicio desde la página de inicio es insulso. Se queda ahí, por la facilidad de hacer un solo menú para todo el sitio, pero se debe tener la funcionalidad de poder incluir o eliminar funciones del menú acorde a las necesidades de cada página. Este problema es recurrente en todas las páginas, no solo en la principal, ocasionando inquietud en el usuario de no saber qué pasó al hacer clic sobre la opción.

Queda completa la lista para que efectúe usted mismo una prueba de su sitio. Haga de su sitio uno excelente en facilidad de uso, revise que no caiga en los errores ya mencionados.
