Information technology — User interfaces — Gesture-based interfaces across devices and methods — Part 12: Multi-point gestures for common system actions

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).

Introduction
A multi‐point gesture is generated by a user with several pointers (which includes an input device such
as a multi‐touchpad, multi‐touchscreen or body parts such as fingertips, hands, etc.) providing gesture
actions using a multi‐point of interest. Multi‐point gestures are used in several commercially available
ICT systems including personal computers, smartphones and video game consoles.
There is a need for an international standard to define the multi‐point gesture so that users do not get
confused. Potential variety and inconsistency among multi‐point gestures might cause a serious
usability problem in using applications on the ICT systems.
This document presents descriptions of multi‐point gestures and their corresponding gesture
commands for system‐level functions and common functions across applications on ICT systems. The
system‐level functions include functions for selecting and initiating applications which are handled by
operating systems or platforms. The common functions across applications are also identified. These
functions include menu navigation, “help”, “undo”, “redo”, and so on.

gestures for common system actions
1 Scope
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).

users see the upper part of the page by using the gesture. The function of the gesture is similar to “page up”.

Introduction
A multi-point gesture is generated by a user with several pointers (which includes an input device such
as a multi-touchpad, multi-touchscreen or body parts such as fingertips, hands, etc.) providing gesture
actions using a multi-point of interest. Multi-point gestures are used in several commercially available
ICT systems including personal computers, smartphones and video game consoles.
There is a need for an international standard to define the multi-point gesture so that users do not
get confused. Potential variety and inconsistency among multi-point gestures might cause a serious
usability problem in using applications on the ICT systems.
This document presents descriptions of multi-point gestures and their corresponding gesture
commands for system-level functions and common functions across applications on ICT systems. The
system-level functions include functions for selecting and initiating applications which are handled by
operating systems or platforms. The common functions across applications are also identified. These
functions include menu navigation, “help”, “undo”, “redo”, and so on.

Multi-point gestures for common system actions
1 Scope
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
