在从传统的Software逐渐转换到Webware的大潮中，设计模式与技术实现双重变革和推进下。我们提倡页面中的任务对应用户群明确，任务少而精。回到我们传统的后台软件系统中，对于面对系统与流程再造。我们顺其自然得想到把在Web服务中的设计思想迁移到后台软件系统中。多数情况来说，这会使系统变得更加轻便，结构清晰，对软件的用户群开始洞察和优化。
但是，是不是有助于提升可用性的改进在软件系统中都需要改进呢? 今天分享一个例子。
背景是：
1， 一个页面中包含一个主要任务和若干分支任务及完成主要任务所需的页面信息架构。
2， 用户角色繁多，信息量大，页面区域有限，只能展示主要任务所需信息。
我们面临其中这样一个挑战：
1， 做出主要任务的决策时，若干条件下需要查看分支任务的详细情况以支持决策。
2， 做出分支任务的决策时，若干条件下需要查看主要任务信息以支持决策。
在开始阶段，我们很自然的对任务所需信息进行归类和梳理，页面更加结构化。大量使用展示层脚本语言，希望让页面更加瘦小，让操作更加流畅。从图中可以看到，把之前的页面跳转改为当前页面弹出一个蒙板浮动层。此时，我们发现忽略了一个问题。页面使用浮动层之后，主要任务和分支任务之间关系由并列变成了包含关系，分支任务又在系统其他环境中处于主要任务地位，任务之间并不存在包含关系。在长达3屏的页面中，浮动层虽然可以做到之前并列关系结构中的自由信息组合、信息对比和自由移动。但是信息量繁复的情况下，移动浮动层，拖拽滚动条，浮动层遮盖部分信息等原因让用户在环境测试时皱紧了眉头。因为之前主次任务之间并列结构、自由打开和隐藏、不规则对比和拖动的习惯不能被延续了。此时，如果不考虑到系统结构本身的问题，此处使用弹出层的使用可以让用户更加自由无束缚，也减小了业务扩展和张力所带来系统调整成本，而时下常用的浮动层反而会限制使用过程。
衡量一个可以提升软件系统可用性特性，它能否适合一套软件系统。不只需要从可用性的角度来审视，还需要深入了解系统结构、用户习惯和技术成本等因素。如果是Web服务产品，需要更加周全地衡量。

How does Adobe Kuler work? What do I need? The only requirements, for using Kuler, are a Web browser with an enabled Flash Player 9 or higher, since it is Flash based. Additionally, you can access the Kuler extension from any Creative Suite 4 product or use the Desktop Air Kuler application.
Whether you are a design professional or a beginner, there will always be a situation, where it’s hard to find the right color theme for a project. This is where Kuler comes in. Kuler not only provides a huge number of color themes, it’s also build on an active community, which creates and publishes the color palettes we are talking about. Let's learn how to set up an Adobe ID, to log in to the Adobe Kuler website, to browse, save, create and publish your own color variations.
Well, you can use Kuler to experiment with colors and copy & paste the color values, but after signing in, you'll get access to download the Adobe Swatch Exchange files, which contain the color themes. It's always stressful setting up all these different accounts on different websites and keeping everything in mind, but Adobe did a good job on this one.
If you already have an Adobe ID, then you can easily login, using the Sign In button located at the top-right corner. You can also click on Register. Adobe will redirect you to their website and guide you through the registering process. After creating an account, come back to continue and login to Adobe Kuler.
Go to the top-right-corner. Click on Sign In and insert your AdobeID and password, then click Go.
Go to the top-right corner and click on Register. You'll be redirected to the Adobe.com website. Click on Create an Adobe account. Fill out the required information and come back to Kuler to Sign In the way described above.
Adobe Kuler is split into different sections. These sections allow you to add or retrieve certain information. Below you can see the single sections with short descriptions, accompanied by images.
Explore color themes by either browsing or searching the Kuler database. You can sort listed themes by Newest, Most Popular, Highest Rated or other random options. By setting a time frame for your results, Kuler will only list themes, uploaded in that time span.
You can narrow down your search results by using the Search bar. You can search by tags, titles, creators or colors. To make it easier for everybody to find the themes you create, you should always choose proper tags.
Color themes, found on Kuler, are submitted by the Community. By creating, saving and publishing your themes on Kuler you make them accessible to everybody. In this section other users can retrieve information about the creator, title, different tags and more.
To give or get some feedback for your themes, add comments. Like on many other websites, you can read comments, but posting comments is only available after Log-In.
The MyKuler section in this image is empty, that's because I've set up a new account, but after creating the first themes, you'll be able store, view, and retrieve all your saved and favorite themes here. You can save themes as favorites, while you are browsing through the database by clicking on the proper button in the details section. You can later import your saved themes to Photoshop.
This section lists information about the current products using or featuring Kuler.
After signing in, you can download the themes you like by clicking on the download Adobe Swatch Exchange file in the details section.
This is how the downloaded files will look like. All Creative Suite 4 products support the exchange of colors via ASE files. For example, you can easily exchange single colors or themes you've created in Illustrator to a Photoshop project. In our case we want to import the files we've downloaded from Kuler.
Go to your Swatches Panel, click on the little triangle in the top-right corner. Next Choose Load Swatches, then Select the proper File type and import it. That's it!
As mentioned above, being a member of the community not only gives you access to the color themes, but also provides commenting and rating which will later help Adobe organize the themes. To leave a comment, go to Add comment. Type in your text, then click submit.
The five-star rating system shows you what the community thinks about the theme. High ranked themes will be listed and ordered when choosing Sort by Highest rated/Most Popular and will be featured on the home page.
So far, we've learned how to browse and download themes, but now we want to create our own color theme. Either click on the button you can see below to edit the current theme or click on Create in the menu to create a theme from scratch. Both will redirect you to the Create page. You can then choose between creating a theme from colors or an image.
Kuler provides very efficient tools to quickly create new color themes. You can choose different harmony rules, use the interactive color wheel and different sliders for brightness and angle, extract colors from an image or simply input color values.
Like the name says, you can choose a Base color and build the color theme around it. After setting the Base color, four other colors are available to choose. Harmony rules will apply to the base color and affect the colors around it. By dragging and dropping on the color wheel, you can adjust the base color. The other colors will then move simultaneously.
The color rules are based on color theory. If you are interested in the theory behind Kuler, check out the links provided below. After selecting the base color, select one of the following rules to quickly create harmonious themes. I think the best way to understand what any single rules does is to experiment with each of them. By selecting Custom, Kuler gives you the freedom to select colors individually.
Move the markers on the interactive color wheel to choose the colors in your theme. Do this by either using a color rule or individually selecting colors. Below the color wheel is another Slider, which adjusts the brightness of the colors.
If the color wheel is imprecise, you can additionally adjust the colors in your theme by inputting numeric values for the HSB, RGB, CMYK, LAB, or HEX color models. If you only want to change a single color, make sure Custom is selected, since entering a new value will adjust all the other colors in the theme. If you want to experiment with the theme, use the color sliders under each color swatch. For those of you who are not logged in, you can easily create themes and copy & paste the values to Photoshop or any other Software.
A very neat feature of Kuler is the extraction tool which generates themes from an image. You can upload images from your desktop or use images from Flickr. Just as the harmony rules, Kuler provides different Moods: Colorful, Bright, Muted, Deep, Dark, and Custom. The moods you can choose from, will automatically generate appropriate colors. By moving the markers around, Kuler picks the color of the current position and displays it, below the image, in the color theme preview. Kuler supports TIFF, JPEG, GIF, PNG, and BMP image formats.
Before saving your themes, you should always give it a proper title and tags to make it easier for other users to find. You can choose to save your themes in private mode to your MyKuler section or share them with other members, who can rate them and add comments. Tags and comments are displayed in the details section. Popular tags are displayed in a certain text size. The larger the size, the more popular the tag word. Creator's can set an avatar or personal color swatch as their default picture. Other members can click on avatars to view all the themes created by that member.
Downloaded Adobe Swatch Exchange files can be used as color swatches in all Adobe CS4, CS3 and CS2 products. We'll take a look at Photoshop CS4.
With the new CS4 version, Adobe integrated Kuler right into Photoshop. You can find it by going to Window > Extensions > Kuler. The Kuler Panel will appear. In case you still don't know what Kuler is or how it works you can read the information, by clicking on the About tab. You can additionally read the Terms of Use and Privacy Policy if you are interested.
This extension provides access to Kuler via RSS feed's. The extension loads the themes directly from the online database. You can also log in to your Adobe account by clicking Window > Extensions > Connections, which will create a connection to Adobe services, while you are using Photoshop or any other Creative Suite 4 product.
The Browse tab reveals a list of currently uploaded and available color themes. To use this feature an Internet connection is required, since the extension uses a RSS Feed to read and list the color themes in Photoshop. You can browse, search and sort themes the way we did on the Kuler website. At the bottom of this section, you can see the arrows pointing up and down. These help you to view the previous or next sets of themes.
The create tab reveals a smaller version of the Create Page on kuler.adobe.com. As you can see, these are the same functions like choosing a harmony rule, adjusting the single colors or brightness, setting the base and related colors and retrieving the values. At the bottom of this section there are additional buttons, which let you upload your theme directly to your account or download/save the current theme.
This is how the standard Swatch Panel looks like in Photoshop. You can open it via Window > Swatches. In a previous step we've learned how to import ASE files to our Swatch Panel. The extension makes it a lot easier for us. We can easily browse and directly add themes to our Swatch Panel though without downloading and importing ASE files from the Kuler website.
The button on the bottom-right-corner, adds the theme directly into your Swatches Panel. You can now select single colors as your Foreground or Background color and apply them to your project. You can reset or delete the colors by clicking on the little triangle in the top-left corner.
So far, we've used the website and extension in Photoshop CS4, but as I mentioned before, there's a cool Air application which runs on your desktop. The only requirements for using it is having Adobe Air installed on your computer.
You can start the installation by double-clicking the Installer. The setup will guide you through the single steps. After you've successfully installed the widget, open it. You should see something similar to the widget in the following image. This Air application works exactly the same way the extension does, providing some extra features. Themes downloaded via the application will be directly added to your Swatch Panel.
You can now browse, search, and save themes directly from your desktop. You can drag individual themes to your desktop, where you can scale them to any size you want, copy swatch values directly from the application or visit the selected theme at kuler.adobe.com to retrieve additional information or comments. I recommend playing with it to get to know the application. It's a really helpful tool to have on your desktop when working with any Adobe Product.
