9、word 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

10、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

11、the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare Internatio

12、nal Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. ISO/IEC 23007-2 was prepared by Joint Technical Commi

This lack of support results in unavailabi

15、lity to utilize such industry ready advanced interaction devices in a standard way. This part of ISO/IEC 23007 presents the list of new data formats for scene specific advanced user interaction devices. It also includes the high-level view of the relationship between semantically recognized informat

Moreover it provides other interface formats of advanced user interaction devices in order to show the applicability of this International Standard with the existing standard.

21、a user interfaces Part 2: Advanced user interaction (AUI) interfaces 1 Scope This part of ISO/IEC 23007 specifies advanced user interaction interfaces (AUI) to support various advanced user interaction devices. The AUI interface is a part of the bridge between scene descriptions and system resources

22、. A scene description is a self-contained living entity composed of video, audio, 2D graphics objects, and animations. Through the AUI interfaces or other existing interfaces such as DOM events, a scene description accesses interesting system resources to interact with users. In general, a scene com

30、 Interaction MPEG-U ISO/IEC 23007 MPEG-V ISO/IEC 23005 4 Overview 4.1 Introduction This Subclause introduces the AUI patterns which this part of ISO/IEC 23007 provides as below. 1. The geometric patterns are a set of geometric shapes which are recognized with sensed geometric information as 2D or 3D

31、 Cartesian positions. Currently, the standard is trying to define the following geometric interactivity patterns: Point, Line, Rect., Arc and Circle patterns. 2. Instead of speaking or writing a word, simple well-known gestures help to communicate with others. For instance, V sign and Rock sign, whi

32、ch are well-known semantics, are already used in various situations. Therefore, the standard provides a container format for symbolic patterns and a classification scheme to enlist well-known symbolic shapes. 3. Many applications adopt well-known touch patterns for users to control themselves. In th

33、is part of ISO/IEC 23007, a container format for well-known touch patterns and a classification scheme to enlist basic touch patterns are provided. 4. This part of ISO/IEC 23007 describes the hand posture and gesture patterns to support the intuitive hand based interaction for scene description. For

34、 example, if a user wants to control an object in a scene description, the user in the real life makes a hand gesture such as grabbing, fist, and open palm which would be a good candidate gesture to support such an interaction modality. In addition, when the user wants to interact with people using

35、hand gestures, “waving a hand” gesture is common semantic to all the human beings, even though the contextual meaning of the gesture may vary.

37、on Sensor Bend Sensor Composite PatternFigure 1 Architecture of MPEG-U part 2 Figure 1 presents the overall architecture of this part of ISO/IEC 23007. User interaction devices such as motion sensors and multi touch interfaces generate the physical sensed information from users environment. Accordin

38、g to the use cases which are mentioned in the context and objectives document for this part of ISO/IEC 23007, a set of physical information can generate a semantic meaning by a recognition process. For instance, some feature points drawn by users finger can be understood as a circle which is specifi

39、ed with a circle center position and a radius value. Therefore, this part of ISO/IEC 23007 provides a set of data formats which describes geometric patterns, symbolic patterns, touch patterns, hand posture patterns and their composite pattern. At the right side of the above figure, other standard ac

40、tivities are also providing similar data structures for new user interaction interfaces such as physical sensors and even new features of mouse and keyboard. Therefore, scene description can use not only the data formats of this part of ISO/IEC 23007 and existing data sets from others. 4.2 Advanced

41、user interaction devices Recently various new types of user interaction devices are available on the market such as multi-touch pad, motion sensing remote controller, etc. Figure 2 shows a few available advanced user interaction devices and Figure 3 shows multi-touch devices currently available on t

42、he market. Figure 2 Motion sensing remote controllers ISO/IEC 23007-2:2012(E) 4 ISO/IEC 2012 All rights reservedFigure 3 Multi-touch devices Among various possible Advanced User Interaction (AUI) Interfaces, multi-touch interface is the first recognized interaction interface to be ready both in term

43、s of device availability on the market and in terms of applicability to various MPEG scene representation standards. Almost unlimited number of actions can be mapped with the combination of 1) the number of fingers touched, 2) the moving direction of each touched finger, 3) the amount of displacemen

44、t of each finger, etc. Therefore, multi-touch interface should be defined by carefully extracting necessary core attributes and make the structure expandable. Figure 4 Hand based 3D interaction Another example among possible Advanced User Interaction (AUI) Interfaces is related to hand based interfa

45、ce shown in Figure 4. If a user wants to select an object and move it to a certain place in the scene, the user in the real life moves his/her hand toward the object, and then move the object while holding and grabbing the object. The user finally releases the object by opening the hand. That is, ha

46、nd postures such as grabbing, fist, open palm, pointing, thumb-up, and thumb-down would be a good candidate posture to support such an interaction modality. The semantics of the postures shall be selected as the descriptions of the shapes, which are independent upon the cultural difference. 5 Intera
