Eliminate all elements that are not helping … UI Design Principles. The user interface provides access to the functions or capabilities of the software system. The following are the golden rules stated by Theo Mandel that must be followed during the design of the interface. Usually less customizable. A well designed user interface is comprehensible and controllable, helping users to complete their work successfully and efficiently, and to feel competent and satisfied. There are two main types of User Interface: Text-Based User Interface: This method relies primarily on the keyboard. Establish meaningful defaults: Always initial set of defaults should be provided to the average user, if a user needs to add some new features then he should be able to add the required features. The following rules are mentioned to be the golden rules for GUI design, described by Shneiderman and Plaisant in their book (Designing the User Interface). Text-Based User Interface or Command Line Interface. Command Line Interface: Command Line Interface provides a command prompt, where the user types the command and feeds to the system. The principles … Making things easier for your users means not forcing them to learn new representations or toolsets for each task. Identical terminology should be used in prompts, menus, and help screens. A typical example of this type of interface is any versions of the Windows operating systems. the alignment is correct or not, spelling checking, position of logo or banners, consistency, easy to navigate with status, colour & brightness of UI and without hesitation to the user. As a result, their … Relies heavily on recall rather than recognition. Software design is a phase in software engineering, in which a blueprint is developed to serve as a base for constructing the software system. So the interface should be designed in such a way to reduce the remembering of previously done actions, given inputs and results. He should interact with the interface just to do his work. The visual layout of the interface should be based on a real-world metaphor: Anything you represent on a screen if it is a metaphor for real-world entity then users would easily understand. Multiple windows allow different information to be displayed simultaneously on the user's screen. Principles of User Interface Design The placement of knobs, buttons, and switches is as essential to the making of a good product as the firmware.
