用户界面 软件工程

什么是用户界面(What is the User Interfacespan style=”font-weight: bold;”>)

The user interface is noting but the platform in between a user and a computer activity. A conjoin or an interface is a set of orders or tariffs through which a user interacts with an application. An order-operate interface is one in which you bypass certain sets of commands. A menu-operated interface is one in which we comment commands of choices from various tariffs displayed.

用户界面注意的是用户和计算机活动之间的平台。 联合体或接口是用户与应用程序进行交互的一组命令或价目表。 订单操作界面是一个您绕过某些命令集的界面。 菜单操作界面是一种菜单界面，我们在其中注释显示的各种价目表中的选择命令。

The UI is one of the most chief parts of any program because it decides how fastly you can make the program and do what you want. A strong program with a badly designed UI has a small demand in the market. Graphical user interfaces (GUIs) that use windows, icons, and pop-up menus have become ideal on personal computers.

UI是任何程序中最主要的部分之一，因为它决定了制作程序和执行所需操作的速度。 具有不良UI设计的强大程序对市场的需求很小。 使用窗口，图标和弹出菜单的图形用户界面(GUI)已成为个人计算机上的理想选择。

用户界面的理想特性 (Desirable characteristics for a User Interface)

It is very chief to denote the characteristics of the desired user interface because if we are not conscious of these, it is very much hard to draw an interactive user interface. A few chief characteristics of an interactive user interface are the following,

表示所需用户界面的特征非常重要，因为如果我们不了解这些特征，则很难绘制交互式用户界面 。 交互式用户界面的一些主要特征如下：

• Rate of Knowledge:

  知识率 ：

  An interactive

  互动式

  user interface should be easy to study. Rate of Knowledge is inhibited by a difficult structure and design of the command issue procedures.

  用户界面应该易于学习。 知识的发布速度受制于命令发布程序的结构和设计困难。

• The pace of Usage:

  使用速度 ：

  The pace of Usage of a user interface is resolved by the time and user effort compulsory to initiate and execute different orders. This attribute of the interface is some times referred to as fertility support of the interface. It indicates how fast users can perform their given tasks.

  用户界面的使用速度由强制执行和执行不同命令的时间和用户努力来解决。 接口的此属性有时称为接口的生育支持。 它指示用户执行给定任务的速度。

• Speed of remembering:

  记忆速度 ：

  Once users know how to use an interface, the rate with which they can remember the command issue procedure should be increased.

  一旦用户知道如何使用界面，就应该提高他们记住命令发布过程的速度。

• Mistake stoppage:

  错误停止 ：

  A good user interface should reduce the vision of committing errors while initiating different commands. The mistake speed of an interface can be normally be determined by monitoring the mistakes committed by average users while using the interface.

  良好的用户界面应减少启动不同命令时犯错误的可能性。 通常，可以通过监视普通用户在使用接口时犯的错误来确定接口的错误速度。

• Charmingness:

  魅力 ：

  An interactive user interface should be charming to use. An attractive user interface catches user attention and desire. Graphics-based user interfaces have definite profits over text-based interfaces.

  交互式用户界面应该很吸引人。 有吸引力的用户界面吸引了用户的注意力和渴望。 与基于文本的界面相比，基于图形的用户界面具有可观的利润。

• Steadiness::

  稳定度 ：

  The orders supported by a user interface should be steady. The basic purpose of steadiness is to allow users to guess the knowledge about aspects of the interface from one part to another.

  用户界面支持的订单应该稳定。 稳定性的基本目的是允许用户猜测关于界面各方面的知识。

• Response:

  回应 ：

  A good user interface must respond to various user actions. Especially, if any user request takes more than a few seconds to process, the user should be enlightened about the state of the processing of his request

  良好的用户界面必须响应各种用户操作。 特别是，如果任何用户请求需要花费多于几秒钟的时间来处理，则应该向用户启发有关其请求处理状态的信息

• User guidance and on-line help:

  用户指南和在线帮助 ：

  Users seek guidance and on-line help when they either forget a command or are unaware of some features of the software.

  当用户忘记命令或不知道软件的某些功能时，他们会寻求指导和在线帮助。

用户指南 (User Guidance)

User guidance denotes replica message, alarms, enhance, and labels, as well as to more formal instructional things provided to help guide a user’s interaction with a computer. The fundamental objectives of user guidance are to promote efficient system use (i.e., quick and accurate use of full capabilities), with minimal memory load on the user and hence the minimal time required to learn system use, and with flexibility for supporting users of different skill levels.

用户指南表示副本消息，警 ，增强功能和标签，以及用来帮助指导用户与计算机交互的更正式的说明性内容。 用户指南的基本目标是促进有效的系统使用(即快速，准确地使用全部功能)，使用户的内存负载最小，从而使学习系统使用所需的时间最少，并具有为不同用户提供支持的灵活性技能水平。

User guidance cannot be merely a decoration added at the end, like frosting on a cake. A study by Magers 1983 has established cogent that good user guidance can result in faster task performance, and will allow the completeness of information handling tasks otherwise impossible for novice users.

用户指南不能只是最后添加的装饰，例如蛋糕上的糖霜。 Magers 1983年的一项研究确立了说服力，即良好的用户指导可以提高任务的执行速度，并使信息处理任务的完整性对于新手用户而言是不可能的。
