信息技术.便携式计算机键盘布局

[中文适用范围]： 就本国际标准而言，便携式计算机被定义为具有屏幕和附加键盘的计算机，能够依靠电池电源长时间运行，并且相对容易通过单个位置从一个位置运输到另一个位置。 个人。 该国际标准为产品设计师提供设计指导；本国际标准指出了 ISO/IEC 9995 和 ISO 9241-4:1998 中包含的在设计便携式计算机键盘时要考虑的要求和建议。 本国际标准力求尽可能保持便携式计算机和台式计算机键盘之间的一致性。 为了实现这一目标，本国际标准审查了 ISO/IEC 9995 和 ISO 9241-4:1998，以确定应遵循的这两个基本标准的设计特征，哪些设计特征不受本国际标准的约束，哪些是允许的变化。 该国际标准主要适用于全尺寸便携式键盘（例如A4）。 它也可能适用于此范围之外的其他键盘。 ISO 9241-4 包含建议的替代方法，通过基于用户表现和主观评分量表的测试来实现一致性。 本国际标准由便携式计算机的两大类指南组成： 1. 布局特征 2. 物理（人体工程学）特征 [外文原描述]： For the purposes of this International Standard, a portable computer is defined as a computer with a screen and an attached keyboard that is capable of running on battery power for extended periods of time and is relatively easy to transport from one location to another by a single individual. This International Standard gives design guidance for product designers; this International Standard indicates those requirements and recommendations contained in ISO/IEC 9995 and ISO 9241-4:1998 that are to be considered in designing portable computers keyboards. This International Standard strives to maintain consistency, as far as practical, between keyboards for portable computers and desktop computers. To accomplish this goal, this International Standard has reviewed ISO/IEC 9995 and ISO 9241-4:1998 to identify those design features of these two base standards which are to be followed, which are exempted from this International Standard and which are permitted variations. This International Standard is intended primarily to apply to full size portable keyboards (e.g. A4). It may also apply to other keyboards outside this scope. ISO 9241-4 contains a proposed alternative method for conformance by a test based on user performance and subjective rating scales. This International Standard consists of two major categories of guidelines for portable computers: 1. Layout characteristics 2. Physical (ergonomic) characteristics
