信息技术用户界面跨设备和方法的基于手势的界面第12部分:通用系统动作的多点手势

[中文适用范围]： 该文件定义了信息和通信技术（ICT）系统中常用系统操作的多点手势。它指定了系统和应用程序识别多点手势的运动和条件。这些多点手势使用输入设备（如多点触控板、多点触摸屏等）或身体部位（指尖、手部等）执行。无论系统的平台或应用程序如何，这些多点手势均以一致的方式操作。用于常见系统操作的手势表示系统级功能以及跨应用程序的常用功能。系统级功能在系统或平台级别执行，包括启动、恢复、重新启动和终止等。跨应用程序的常用功能是指在同一系统或平台上各种应用程序中常用的导航菜单、打开对象、关闭对象等功能。注：ICT系统包括但不限于数字电视、机顶盒、视频游戏控制台、通信设备、互联网设备、娱乐设备和个人计算机（PC）。 [外文原描述]： This document defines multi-point gestures for common system actions used in information and communication technology (ICT) systems. It specifies movements and conditions for describing multi-point gestures recognized by the systems and applications. The multi-point gestures are performed using an input device (multi-touchpad, multi-touchscreen, etc.) or body parts (fingertips, hands, etc.). These multi-point gestures are intended to operate in a consistent manner regardless of systems, platforms or applications. The gestures for common system actions denote system-level functions and common functions across applications of ICT systems. The system-level functions are executed at a system or a platform level. They include initiation, resume, restart and termination, etc. The common functions across applications are commonly executed among applications of a system or a platform. The functions include navigation of menus, opening an object, closing an object, etc. NOTE ICT systems include, but are not limited to, digital televisions, set-top boxes, video game consoles, communication devices, internet devices, entertainment devices, and personal computers (PCs).
