When moving around, people are encountering different kinds of hardware, all c

14、apable of communicating with the Internet, but having different user interfaces, such as computers with different national keyboards, mobile telephones and TV sets. The purpose of this Technical Report is to provide a way to make access as uniform as possible in a culturally and linguistically accep

15、table way so that users can have the almost the same personal user interface to their environments on the Internet wherever they go. Some areas of concern are the different keyboards or other inputting devices, different protocols for accessing the personal user environment via the Internet, and hav

16、ing uniform access to different Internet hosting environments. The data in this Technical Report is meant for a general audience and is not specifically meant for research/engineering.

22、ponses to requests from other software programs, which are frequently on other remotely connected computers 3 Technology 3.1 Purpose The problem at hand is to match the preferences of a user to the system at hand, including hardware and software. The user preferences are specified as a preference bu

23、ndle. The preference bundle is specifying all preferences of the user, including cultural preferences, accessibility preferences, and personal preferences. A specification of a preference bundle format is given in Clause 4. There can be multiple preferences for the same job, so a way to weight the m

24、ultiple preferences is needed. The system is specified with its hardware and software capabilities. Finding a solution would then be a matter of capability matching to the user preferences. The user can be presented to a way to modify the selected choice of settings. The scenario is that a user can

25、use systems everywhere in the world, in a way that best fits the users preferences. An example is people on a journey, who use equipment like a keyboard suited for a foreign culture, for example, at a net caf or at a hotel. The user would then be able to run programs in a language of choice of the u

26、ser and with input possibilities fitted to make the user able to operate conveniently in the language of choice. This could possibly be run as a service over the Internet. 3.2 User preferences The user preferences are specified as a number of personal preferences, and a number of more general prefer

27、ences, such as cultural preferences on language and cultural conventions. The user preferences would be extensible and with alternate possibilities with preference weights attached. The user preferences would be able to reference other user preferences, including more generically specified preferenc

28、es such as cultural and linguistic preferences. The user is able to obtain the preferences over the network everywhere in the world. The data could also be obtained from a local source, such as a usb stick. 3.3 System capabilities The system capabilities is specifiable in an extensible format, and a

29、ble to include other system capabilities, such as hardware and software capabilities of an accessing system, in combination with services obtained via the net. 3.4 Technology and standards To accomplish this, it is necessary to have a specific standardized format for user preferences and for system

30、capabilities, plus a method to access such information over the net in a personalized way. A way to do this is with XML formatted files and access protected file retrieval over an https connection. Several information service providers, including the users own services, could provide the preferences

31、 information, possibly via a user-id (email) or profile id and optionally a passcode or other identification mechanisms. The specialized software could be easy to install but could also for convenience be part of the operating system environment. The algorithm for capability matching to preferences

32、could be standardized. The capability matching could use existing matching algorithms and be implementation defined.2 ISO/IEC 2015 All rights reserved ISO/IEC TR 30109:2015(E) 4 APIs, se rvic es and file formats 4.1 User preference settings program This subclause specifies formats and contents of us

33、er preferences and system capabilities. It also specifies services to obtain such information. For the local system to obtain and set the users preferences, a program needs to be available on the local system responsible for the inputting and outputting for the user that can retrieve a file with the

34、 user preferences and set preferences accordingly. The users preferences settings program will need to contact a preferences server for the users preferences information. A preference server is a web (https) server that is capable of delivering a file with a personalized profile, given the profile i

35、dentification and optionally a passcode. Info on servers can be found on the SC 35 web site at http:/ /www.open-std. org/jtc1/sc35/wg5/ . The users preferences settings program could have one preferred user information settings server, and a possibility to choose amongst other information servers, p

36、lus a possibility for the user to type in a self-chosen user information server. The users preferences retrieval program lets the identification and retrieval services identify the user and deliver a file with the users preferences. The communication could preferably be done on a secure protocol suc

37、h as the https. From the information retrieved, the users preferences settings program determines the best match from available resources and taking into account available permissions, updates system and application settings accordingly, including installed applications, installed accessibility func

38、tionality, menus, application preferences, and cultural and language settings including input method choice. If the users preferences are elaborate, the settings update processing could be time consuming and error prone, for example, when installing new applications or installing new language versio

39、ns or when direct matches are not possible. For selected generic settings such as language and culture profiles and for simpler settings like keyboard settings, matching of the user profile to the system capabilities could in many cases be not too demanding on local system resources. Also, for syste

40、ms where most processing is done in the powerful cloud and the local system only handles the graphical environments and the inputting environment including a keyboard, this would be not too demanding on local system resources. 4.2 User preference delivery service The user preference delivery service

41、 has the duty to identify the users preferences and deliver a users preferences file to the user preference settings program. The identifying of the user preferences could be allowed to be done in multiple ways, including a specific userid/passcode identification scheme local to the system, use of o

42、ne or more certificate based identifications schemes such as Verisign, CAcert, OpenID, pgp or gpg, use of one or more other external identification schemes such as those provided by vendors (for instance, Google, Facebook or Microsoft) and a generic identification of culture and language profiles, t

43、he latter most likely without a passcode. A common way of identifying a user is using the email address of the user. An email address includes a which can be difficult to find on a foreign keyboard. The first occurrence of the sequence , two period characters, can be used instead of the character to

44、 facilitate easier typing of this form of identification. Once the user identification has been established, the user preference delivery service sends a file with the user preferences corresponding to the identified requirement. It is the responsibility of the user preference delivery service provi

45、der to provide a means of registering user preferences and/or generic profiles and storing such information. The service could allow a possibility to incorporate and edit other duly obtained preference profiles. Users could be allowed to indicate if their profile could be read without restrictions b

46、y other users. This could be presented to the user in a culturally and linguistically adequate way. ISO/IEC 2015 All rights reserved 3 ISO/IEC TR 30109:2015(E) 4.3 User pr efer enc es information file format The user preference information file could be an XML formatted file. The encoding of the fil

47、e is UTF-8. The XML could allow incorporating of other preferences. Specific mark-up includes the following: tag “locale” with parameters “name” and “weight”; tag “keyboard” with parameters “name”, “data” and “weight”; tag “input_method” with parameters “name”, “data” and “weight”. Names here can be

48、 various identifications for Japanese, Chinese or Korean IMs, or more general IMs like the ones specified in ISO/IEC 9995, ISO/IEC 14775, the mnemonic IM in RFC 1345, or the Global-IM described in 4.5; tag “system” with parameters “name”, “data” and “weight”; tag “application” with parameters “categ

49、ory”, “name”, “data” and “weight”. NOTE 1 The “data” parameter is able to contain arbitrary data in any format so that, for example, all kinds of preferences files for all kinds of applications can be applied. NOTE 2 Tags with the same name in the user preference information file and in the system capabilities file match each other and the parameters are for matching the user preferences against the system capabilities.
