有没有衡量 java web GUI 设计有效性的指标？
对于我的 Java Web 应用程序的特定 GUI，我的团队的一些成员设计了不同的 Web GUI。每个设计的 GUI 都有自己的优点和缺点。是否有一个指标来评估 Web GUI 并为每个设计的 GUI 打分“优秀分数”？我想选择得分最高的 GUI。或者有什么工具可以用于此评估？
For a specific GUI of my java web application, some members of my team have designed different web GUIs. Each of the designed GUIs has its own pros and cons. Is there a metric to evaluate a web GUI and score each designed one a “goodness mark”? I want to pick up that GUI that has the highest score. Or any tools is available for this evaluation?

事实并非如此，因为“善”对不同的人来说意味着不同的东西。在网站上，您可以衡量有多少人通过不同的界面变化进行结账，或者他们找到他们正在寻找的页面的速度或他们在网站上停留的时间等。
您可以衡量一些东西已知的标准，例如可访问性，还有一些非常通用的设计原则（网格布局通常比随机混乱更好，例如，按钮位置和顺序的一致性是另一个）。
如果您的应用程序有足够多的用户来形成合理的样本量，那么典型的方法是 A/ B 测试，向不同的人提供不同版本的界面，看看会发生什么。但是，您仍然需要决定衡量的目标（销售数量、网站停留时间等）来比较两个版本。
如果您的用户群较小或者这是一个内部应用程序，那么直接用户反馈可能是更好的选择 - 即直接询问他们他们认为哪个更容易/更好使用。
Not really, because "goodness" means different things to different people. On a web site you might measure that as how many people make it to the checkout though different interface variations, or how quickly they find a page they're looking for or how long they stay on the site etc.
You could measure some things against known standards, accessibility for example and there are some very general design principles (a grid layout is generally better than random jumble for example, consistency in placement and ordering of buttons is another).
If your application has a sufficiently high number of users to make a sensible sample size then a typical approach is A/B testing where you serve different versions of the interface to different people and see what happens. However, you still need to decide on a goal to measure against (number of sales, time spent on site etc) to compare the two versions.
If you have a small user base or this is an internal application then direct user feedback might be the better option - i.e. just go and ask them which they find easier/better to use.
您可以尝试“有用性”与“易于使用”指标。
让一些用户坐下来对两个变量的 UI 评分为 -10 到 10，并绘制它们在不同颜色的图表中，显然左上角的点越多越好。
我经常使用这种方法，因为它可以在 10 分钟内完成，并且您可以根据项目范围切换“变量”。
只是我的 2 美分
You can try the "usefulness" vs "easy to use" metric.
Get some of your users sit down to rate UI with -10 to 10 on both variable, and plot them on the graph with different color, obviously more dots on top left is the better one.
I use this approach a lot as it can be done in like 10 minutes, and you can switch the "variable" depend on the project scope.
just my 2 cents
在真实客户身上进行测试。他们感到最满意的产品就是他们最有可能继续向您付费的产品。那是最好的图形用户界面。
Test it on real customers. The one they feel most content with is the one they are most likely to continue paying you for. That's the best GUI.
这实际上是一个个人调用，具体取决于 GUI 的预期目的及其未来的用户。如果它是为视力障碍人士设计的，我会使用大而清晰的字体和按钮，可能还会使用声音。这实际上取决于您的需要。
您应该制定自己的指标，并根据所需的偏好对选项进行排序（甚至赋予权重）。
对于可访问性，有一些自动工具，例如用于 firefox 的 HTML Validator。
This is really a personal call, depending on the intended purpose of the GUI, and its future users. If it's intended for sight-impaired people, I would use large and clear fonts and buttons, and possibly sound. It really depends on what you need.
You should make your own metric, and sort (or even give weights to) the options according to the desired preferences.
For accessibility, there are automatic tools, e.g. HTML Validator for firefox.
