user interface design principles
A question-and-answer session provides an interaction where the direction is dictated by the user interface. Besides wasting time because of the drop-down animation, it also wastes our "mental bandwidth." A very important factor of intuitive design is the amount of 'mental bandwidth'—the amount of time it might take our mind to comprehend something—it uses. A product also needs to be compatible with the devices that would tend to be used alongside it. When people interact with a product or a device, they need to understand how to approach the UI and enjoy the interaction enough to continue using the product. To avoid that, make the actions easy to backtrack. Let's take a look at a real life example. The more of the user interface's functionality that is visible to the user, the easier it will be to learn the whole device, and the more obvious it will be what the device is capable of doing. The user interface design mainly deals with graphical user interface (GUI) design, which involves multiple characteristics like graphics of the UI, Icons, Windows, Menus, font size, color, alignment, space between lines, etc. I call this multiplexing a control. Intuitive UX lessens the need for explanations. Group controls inside Group controls are not recommended unless there are no more than 2 or 3 of them inside one large Group control. Icons—especially the Windows XP and Office 2003 icons and toolbar bitmaps—help speed up cognition of the UI and the task the user has to perform. Users find it unpleasant to be told they have made a mistake, so design fewer paths that end in error messages. Instead of reinventing the wheel, stick with solutions that people are already used to. There are some basic rules to follow to have a much nicer looking and better functioning UI for your application. Why? Microsoft recently released a preview version of a graphics application, Expression Graphics Designer (formerly codenamed "Acrylic"). This is the last technique of the user interface design. The user can quickly decide what to do without searching for anything in the Help file or opening another window. Developers and tech-friendly people know what that means, but a novice user could possibly think that you could let another user on the other end of your chat use your Web cam, too. Some attempts have been made to standardize alarm sounds and lights in hospitals, but that is a long way from standardizing the whole interface. One of the ways to keep the paths short is to use the data already available from the device output. If you can make the wizard a bit graphical (see the Use Pretty Graphics section), it makes the configuration task that much easier. Using an embedded interface should be as natural as using a tool from your toolbox. This site uses Akismet to reduce spam. A professionally designed splash screen or a header (like the one we talked about earlier) does the trick. The interface is directed enough that the novice does not get lost, but more than one option is available at each step. The Windows Installer wizards are perhaps the most popular headers: a simple icon in the far right; a title label describing the dialog (for example, Select Installation Folder); and a sub-heading that describes the purpose of the dialog (for example, Select the folder where the software files will be installed). An automatic teller machine that has been asked for too much money will display a polite message telling you that you are not rich enough. It states that the writer should keep the text conversational. Sometimes, no amount of grouping, sizing, or spacing can help you when you have many important controls. It does not require too much investment of time or money on your part, and adds a good return on investment. In such cases the modes will seem natural and necessary to the user. We should emphasis on the performance issue of the UI. This is one of the concepts of user interface design for the software application which deals or affects the budgeting of the application. Wizards are also a good way to help set up the initial configuration of your application. However using an internal mechanical or electrical limit can have the disadvantage that the user may believe that the belt is moving at the entered speed, instead of at the limiting speed. More often than not, a white header over a standard Windows intrinsic control face color will do. In this case the ACCEPT key was placed beside the figure being accepted to encourage the user to look at the digits they have just entered before committing them. Multithreading of an interface does not necessarily require the software to be multithreaded. A JIT-Debugger or a critical error dialog is not a good thing. Until you examine the controls you do not know if this device is only for copying, or rewinding tapes, or whether it can actually play the tape. When you have to drop down the ComboBox list and select the second item (out of only 2 items) it can be really irritating. User Interface Design Principles User interface designs must be functional and purposeful. Often there are tasks that require the user to wait. These kinds of "little things" are the core of the overall impression. The following examples provide tips on improving your applications with real-world tips and tricks. A dial graduated in degrees Fahrenheit does not need to be marked FURNACE TEMPERATURE, assuming that there are no other temperatures settable on the furnace. But what do those buttons actually do? Sometimes, headers can even help you accommodate navigation and commands within them as well. Your hammer does not ask you if you want to hit something, just before impact. You cannot always afford to hit the undo button just to find out what will happen. It always welcomes to change or modify the UI depends upon the user or client reviews. Such windows are best used for background processing such as downloading an update or performing a scheduled task, and should never be set to "Always on top.". Microsoft AntiSpyware downloader/updater or the Norton AntiVirus e-mail scanning toasts are good examples of this. With Visual Studio 2005, you can even have Groups for additional categorization. Check your email for a link to verify your email address. Otherwise the user may feel disconcerted. People who see familiar things are more likely to stay and interact with the interface. If there was a single thread of control, operations on the monitoring side would cancel incomplete actions on the settings side and vice versa. The same considerations apply to size.

In the following screen shot you can see a similar custom message box, but with an added advantage—a timer shown visually with the help of a progress bar. Resolution-independent windows look the same whether you use 96DPI or 300DPI screens. Sometimes you need to direct the user to the most important buttons even when you have four or five other buttons lying around it. The standards include everything from the layout of controls in a particular manner on the dialog boxes—like the OK and Cancel buttons, the user interface's shape—rounded-corners of the top of the window as in Windows XP dialogs, styles of icons, styles of any other graphics, interactive behavior of your application, and the like. Instead, cycling through each by popping/fading one toast after the other would be better. Intuitiveness is also born from familiarity. The effort taken to undo the action is equal to the effort taken to perform the action in the first place-leading to a robust system. This concept of UI design technique involves the visibility of user interface for a software application. In the Windows User Experience Interaction Guidelines, a very important point has been made about "Text Tone". But worse is when they are waiting without knowing what is happening. For example, if the belt is physically limited by its motor to a top speed of four feet-per-second, but the user can enter five feet-per-second, the user may make other decisions based on the assumption that the belt is actually moving at five feet-per-second. Too much bold text is confusing and reduces the overall impact of the form. However, this also means that you lose the ability to rewind a tape while listening to the radio-something users may find useful. We are used to thinking of robustness as a mechanical property. These same options are used by the standard MessageBox.Show method. {| foundExistingAccountText |} {| current_emailAddress |}. But if you really want to make sure no special theme or custom colors mess up your header, draw a. Simply, the UI design principles provide the software product user interface/view with focus on look & feel and style i.e. Use the ShowDialog([OwnerForm]) method from the parent form. While Jakob Nielsen’s 10 Heuristics for User Interface Design is probably the most popular set of heuristics out there, there are others. Spacing between two controls is important. A good alternative is to specify what you want the user to do: "Select the folder where you would like to place these files." ISO 8601 is a standard for date and time formats. Sometimes you may need to show multiple items by the toast. The idea that users will be scared of a device with too many controls is a myth. A tape recorder (and they do exist) with a fast forward button but no reverse button will be frustrating because the user will have to turn over the tape to undo the action taken when he wound forward too far.
