ergonomics

This text explores the significance of ergonomics in interface design, particularly in industrial settings. It examines physical characteristics of user interaction, emphasizing standards for control arrangement, environmental conditions, and health considerations. The differences between office and industrial interfaces are highlighted, focusing on data type, environment, and user interaction. Additionally, modern glass interfaces are discussed, showcasing their flexibility and challenges such as loss of context and feedback issues. The importance of adapting interface design to user needs and safety standards is underscored.

  1. ergonomics physical aspects of interfaces industrial interfaces

  2. Ergonomics • Study of the physical characteristics of interaction • Also known as human factors – but this can also be used to mean much of HCI! • Ergonomics good at defining standards and guidelines for constraining the way we design certain aspects of systems

  3. Ergonomics - examples • arrangement of controls and displays e.g. controls grouped according to function or frequency of use, or sequentially • surrounding environment e.g. seating arrangements adaptable to cope with all sizes of user • health issues e.g. physical position, environmental conditions (temperature, humidity), lighting, noise, • use of colour e.g. use of red for warning, green for okay,awareness of colour-blindness etc.

  4. Industrial interfaces • Office interface vs. industrial interface? • Context matters! • office industrial • type of data textual numeric • rate of change slow fast • environment clean dirty • … the oil soaked mouse!
