10、tion 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 respec
11、tive 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. International Standards ar
12、e drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies fo
13、r voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 14754 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 35, User interfaces. Copyright Internatio

15、 input mode have been produced. These systems recognize gestures as commands, unfortunately these gestures vary from one system to another. In particular, the gestures conventionally used to make changes to the layout and content of text differ across systems. This International Standard specifies a
16、 set of basic gestures which will enable the user to operate a system regardless of its country of origin or specific manufacturer. The advantage of these gestures lies in the fact that the indication of a location and the indication of an action to be performed on the object at that location can bo
17、th be carried out simultaneously. The gestures chosen to indicate such functions are the most commonly used. These are essentially the kind of gestures covered by this International Standard. This International Standard consists of 8 clauses and covers commands for two types of required functions an
18、d also some optional functions.

20、on technology Pen-Based Interfaces Common gestures for Text Editing with Pen-Based Systems 1Scope This International Standard defines the basic gesture commands for text editing with pen-based systems and defines the user actions required to have the system execute these commands. The feedback to th
21、e user when a gesture command has been correctly recognized is also defined. This International Standard does not define the user actions necessary for the input of characters. 2Conformance A system conforms to this International Standard if it conforms to clauses 6, 7 and 8. 3Normative references T
22、here are no International Standards referenced. 4Terms and definitions For the purposes of this International Standard, the following definitions apply. 4.1 action point point on the digitizer display where a gesture command will be executed 4.2 digitizer device which can detect the position touched

32、tions and the corresponding gesture commands as described in this clause. 6.1 Select 6.1.1 Function The select function shall identify the area for subsequent editing commands, such as move or copy. The continuous string of characters (including space) from the start point to the end point becomes t
33、he selected area. 6.1.2 Gesture The select gesture shall consist of the following elements: touchdown, pause, system feedback, continuation of the stroke in any direction and lift-off (see Figure 1). To initiate the select gesture, the user touches the screen and pauses until the system feedback is
34、visible and then continues the stroke in any direction. The stroke does not have to be a straight line. 6.1.3 Feedback Visible feedback shall be provided to the user when the system recognizes the entering of a “select” command. Within the limitations of the technology, when the user continues the s
35、troke, there shall be visible feedback to indicate the current extent of the selection. Where possible, audible feedback should accompany this command at the “pause” point. Examples Figure 1 Gesture for the select function Visible feedback shall be provided to the user when the system identify the e
36、ntering of a “select” command. Within the limitation of the technology, when the user continues the stroke, there shall be visible feedback to indicate the current extent of the selection. Visible feedback shall be provided to the user when the system identify the entering of a “select” command. Wit

39、 sequences of elements: a) Touchdown, a stroke of at least four segments in a zigzag manner as shown in Figure 2a and lift-off. The segments of the zigzag should be about the same length and the segments may overlap. b) Touchdown, drawing of two segments of “V” which are drawn from top downward righ
40、t followed by a right upward segment as shown in Figure 2b and lift-off. The action point shall be the start point. The length of the second segment should be more than twice as the first one. Note1: If both gestures, a) and b), are available on the system, then the user should have the option to di
41、sable one of them. Note2: The stroke of these gestures may have no visible trail.
