Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www. iso. org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www. iso.o rg/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www. iso

Introduction
This document provides definition, syntax, structure and explanation of GIML (Gesture Interface
Markup Language) which is used to formally describe gestures for gesture-based interfaces of ICT
products, systems and services. The gestures are recognized by the gesture software for the gesture-
based interfaces and translated into corresponding gesture commands of the ICT products, systems and
services. Some examples of the gestures are defined in international standards such as ISO/IEC 30113-
1 and ISO/IEC 30113-11.
GIML is defined in terms of XML (Extensible Markup Language) which is a special subset of SGML
(Standard Generalized Markup Language). It is useful in exchanging data in various ICT products and
services and used to describe syntax and features of the standard gestures.
GIML is designed to achieve the following goals:
— The standard gestures are formally and consistently defined in a well-formed format.
— The standard gestures are concretely expressed as both human-readable and machine-readable.
— The information of the standard gestures is exchanged and shared among ICT products, systems
and services.
This document focuses on the syntax and the structure of GIML. The XML schema of GIML is presented
in Annex A. Some examples of GIML are listed in Annex B.

1 Scope
This document defines GIML (Gesture Interface Markup Language). The syntax and the structure of
GIML are described in this document.

4 General
GIML is used to describe syntax and features of gestures which support interactions between human
users and gesture interfaces of ICT product, systems and services. The gesture interfaces provide
information and controls for the users to accomplish specific tasks as defined in ISO/IEC 30113-1. They
include mice, touch screens, 3D mice, joysticks, game controllers, wired gloves, depth-aware cameras,
stereo cameras, etc.
The gestures of the users are translated into gesture commands for the ICT product, systems and
services. According to ISO/IEC 30113-1, gesture software implements functionalities of the gesture
interfaces including gesture recognition, command processing and feedback generation. Some of the
standard gestures are single-point gestures for common system actions as defined in ISO/IEC 30113-11.
Since GIML is used to describe syntax, structure and schema (as specified in Annex A) of the standard
gestures in a well-formed format, the GIML-based descriptions are used in developing gestures,
gesture interfaces, gesture software, etc. The GIML-based descriptions of the standard gestures can be
understood by human and machines. Also, the description of the standard gestures can be utilized in
exchanging and sharing information about the gestures.

5 Syntax and structure
5.1 General
The syntax and the structure of GIML are defined in this Clause. The GIML elements and the GIML
attributes are defined. The elements are used to define gestures in a formal way. The attribute is used
to present additional and more detailed information of its associated element.
5.2 Elements
5.2.1 General
The GIML element shall be defined using a start tag, an end tag and its content.
A start tag shall be defined as a string which is a concatenation of the symbol “<”, the name of the
element, optional attributes of the element, and the symbol “>”.
An end tag shall be defined as a string w
