29. Current definition: �E&IT� Electronic and information technology.� Includes information technology and any equipment or interconnected system or subsystem of equipment, that is used in the creation, conversion, or duplication of data or information. The term electronic and information technology includes, but is not limited to, telecommunications products (such as telephones), information kiosks and transaction machines, World Wide Web sites, multimedia, and office equipment such as copiers and fax machines. The term does not include any equipment that contains embedded information technology that is used as an integral part of the product, but the principal function of which is not the acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or reception of data or information. For example, HVAC (heating, ventilation, and air conditioning) equipment such as thermostats or temperature control devices, and medical equipment where information technology is integral to its operation, are not information technology.

31. Proposed definition: �ICT� Electronic and Information Technology (E&IT).� This is also referred to as Information and Communication Technology (ICT).� This includes information technology and is any equipment or interconnected system, or subsystem of equipment, which is used in the creation, conversion, duplication, automatic acquisition, storage, analysis, evaluation, manipulation, management, movement, control, display, switching, interchange, transmission, reception, or broadcast of data or information. ICT includes, but is not limited to: electronic content, including email, electronic documents and Internet and Intranet web sites; telecommunications products, including video communication terminals; computers and ancillary equipment, including� external hard drives; software, including operating systems and applications; information kiosks and transaction machines; videos; IT services; and multifunction office machines that copy, scan and fax documents.

33. What�s different �ICT� instead of �E&IT� Definition separated from provision (�principal function� [E103.3.2]) New examples of content: email, video communication terminals, electronic documents  E103.3.2 Components of an ICT System.� When ICT is a system of interoperable components, the provisions of this part shall apply to each interoperable component that has a user interface, or transmits information. Exception:� When ICT is a component of a system where the principal function is not ICT, then the provisions of this part shall only apply to the ICT components which have a user interface or transmit information. Advisory E103.3.2 Components of an ICT System.� An example of ICT that is a system of interoperable components is a personal computer.� In this example, the interoperable components are the CPU, the display monitor, the keyboard, the mouse, and any attachments (such as an external hard drive, removable flash drive, and printer).� Each of these interoperable components is required to conform to the applicable provisions of this part. An example of an ICT component that is not required to conform to the provisions of this part is the motherboard inside the CPU, because it does not have a user interface. The covered components may not necessarily be in the same physical location.� An example of an ICT system required to conform to the provisions of this part is a service that provides for telephone callers to adjust a thermostat or turn on a building security system and lights. Advisory E103.3.2 Components of an ICT System Exception.� Vehicles, such as cars, boats and planes, are not ICT because the principal function is not ICT.� Some ICT found in vehicles would be covered where the principal function is ICT.� Examples of covered ICT components in vehicles include:� laptops fixed inside a vehicle used by a Federal uniformed security officer, car phones, and video players mounted in vehicles.� Electronics used in the operation of a vehicle are not ICT.� An example of electronics that are not covered is the dashboard of a car.

35. Agenda Big Change: More Documents, More of the Time, for More People Full scope TBD What are some expectations for accessible electronic documents? Using WCAG 2.0 Success Criteria as benchmark Examples of using MS Word for making accessible documents Advisory 501.1 Scope.� The provisions of this chapter apply to electronic documents, which are mostly static, read-only, non-interactive electronic content.� Examples include Word files, PDFs, PowerPoint presentations, Excel spreadsheets, and simple web pages (which do not contain Flash).� However, electronic documents may also contain interactive content, such as hypertext links, buttons, and form elements or fields.� All of these elements are covered in this chapter.� Electronic content covered by this chapter includes most non-paper documents and web content, regardless of format. This chapter is oriented towards document authors, rather than developers.� Provisions relevant to more robust user interaction, including scripting, are found in Chapter 4 (Platforms, Applications, and Interactive Content). Additional requirements for audio and video content are found in Chapter 6 (Synchronized Media Content and Players).Advisory 501.1 Scope.� The provisions of this chapter apply to electronic documents, which are mostly static, read-only, non-interactive electronic content.� Examples include Word files, PDFs, PowerPoint presentations, Excel spreadsheets, and simple web pages (which do not contain Flash).� However, electronic documents may also contain interactive content, such as hypertext links, buttons, and form elements or fields.� All of these elements are covered in this chapter.� Electronic content covered by this chapter includes most non-paper documents and web content, regardless of format.

36. Why WCAG? Why not use draft provisions? We know we will be making changes. We don�t know what the final language will be. Why use WCAG 2.0 language? We know we will be harmonizing� We do not know the details of how!

37. WCAG 2.0 Virtues Publically vetted, lots of input 9+ years active work! Attention paid to plain language But there is still a learning curve WCAG 2.0 Success Criteria Written to be technology neutral Written so they can be evaluated as true/false statements Each Success Criterion is written as a statement that will be either true or false when specific Web content is tested against it. The Success Criteria are written to be technology neutral. All WCAG 2.0 Success Criteria are written as testable criteria for objectively determining if content satisfies the Success Criteria. While some of the testing can be automated using software evaluation programs, others require human testers for part or all of the test. Principles -> Guidelines -> Success Criteria Vernacular: �normative�, �programmatically determinable�, �accessibility supported�Each Success Criterion is written as a statement that will be either true or false when specific Web content is tested against it.
