Study Notes
User Interface Design Principles
- The system must be easy to learn, enjoyable to use, and evoke a sense of pleasure and accomplishment, not tedium and frustration.
- The interface should serve as a connector and a separator, connecting users to the computer's power while minimizing the possibility of users damaging each other.
Principles for the Xerox STAR
- The design of the Xerox STAR was guided by principles that evolved over its development process, establishing the foundation for graphical interfaces.
- Key principles include:
- Displaying selectable and manipulable objects as single-page entities.
- Providing unlimited navigation paths with contextual clues.
- Basic interaction involves a single click.
- Presentation style is artistic, individual, and unrestricted.
Principles of User Interface Design
- An interface must be an extension of a person, reflecting their capabilities and responding to their specific needs.
- The interface should be useful, accomplishing business objectives faster and more efficiently.
- The interface must provide the appropriate emotional effect for the product and its market.
- The interface must match the capabilities of the device on which it will be displayed.
General Principles
- The design goals for creating a user interface include:
- Aesthetically pleasing: providing visual appeal by following presentation and graphic design principles.
- Providing meaningful contrast between screen elements.
- Creating groupings and aligning screen elements and groups.
- Providing three-dimensional representation.
- These principles are general characteristics of the interface and apply to all aspects of GUI and Web design.
