HMI Quality: The quality of the Human-Machine Interaction (HMI) is a primary concern of usability engineering. == Definition == The HMI quality may be defined by the system utility (usefulness), in terms of the user tasks, obtained by task analysis. This is in contrast with automated systems, for which the quality is typically defined by attributes such as performance, reliability and recovery costs of the system units.〔 (), Zonnenshain & Harel: Task-oriented SE, INCOSE 2009 Conference, Singapore 〕 Unlike automated systems, for which the system utility depends primarily on the system availability, performance and reliability, the utility of the HMI interaction is affected mainly by the user’s performance and reliability, in the context of the user’s expectations. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HMI quality」の詳細全文を読む スポンサード リンク
