Key Factors Influencing Effective Interface Design in Software Systems

Interface design is critical for user interaction with software systems. This guide discusses the key factors affecting interface design, including user demographics, their familiarity with technology, training, and the specific information that needs to be conveyed. It explores the context of use, such as varying lighting conditions between environments like offices and shop floors. Furthermore, it addresses the hardware used for interaction, highlighting how it determines the interface style, whether through touch screens or keyboard inputs, and the expected output type, like text or diagrams.

  1. Software Factors Affecting Interface Design

  2. Learning Objectives • Discuss the factors affecting interface design.

  3. Factors affecting the design of an interface • Who will be using it? • Ability of workers with computer systems? • Have they received training/are they used to computer use? • What information needs to be conveyed? • Under what circumstances must it operate? • The environment in which the system would be used… • Lighting conditions on a shop floor may be different to those in an office. • How effective will it be in conveying the information?

  4. Factors affecting the design of an interface • What hardware is going to be used to communicate in the HCI? • This will determine style of interface, e.g. touch screen input or keyboard. • What output will be expected from the computer? • An office will probably use text while a shop floor will probably need diagrammatic responses. • The hardware that is going to be used to communicate in the HCI will determine style of interface, e.g. touch screen input or keyboard.
