Human Factors for Informatics UsabilityB. Shackel, S. J. Richardson Human factors are a critical issue in informatics or information technology systems as the computer industry realizes the need to change from technology-dominated goals to the needs of computer users. The study of human factors can help to improve the usability of information systems and to help reduce the huge costs of human-computer interactions. However, information technology equipment is not easy to use. Even specialists in computing and information technology have difficulty with equipment produced by other experts. This book shows how knowledge and methods from the field of ergonomics can be used to help make information technology equipment easier to use. The principal audience is the many designers, software and hardware engineers, system design managers, management service managers, and user managers who are now becoming aware of the importance of usability. This book provides not only an introduction and overview but guidance on what they can do and how they can approach the problems of usability in informatics equipment. |
