"The power of the web is in its universality. Access by everyone regardless of disability is an essential aspect."
Tim Berners Lee, inventor of the World Wide Web and Director of W3C
Digital accessibility means enabling everyone, and especially those with a disability, to use computers and software, and to use or create digital resources on every type of device (computer, mobile phone, tablet, etc.).
Digital accessibility addresses every type of disability: visual, auditory, motor, cognitive, technical, etc.
SPIE is involved in this social movement, and is committed to providing you with a fully accessible website that achieves WCAG (Web Content Accessibility Guidelines) 2.0 AA-level compliance.
This website has been designed to comply with the web standards set by the W3C (World Wide Web Consortium), and the web content directives published by the WAI (Web Accessibility Initiative). As a result, this website is accessible to all web users, including seniors and disabled users with functional limitations.
Websites that comply with accessibility standards benefit all users.
This website is compatible with all relatively new browsers offering HTML 4.01 and CSS 2 compatibility, and is compliant with the XHTML and CSS vocabulary and syntax recommended by W3C.
Consequently, this website will perform best with the latest versions of today's browsers, whilst remaining usable with older versions.
The following browsers are recommended:
- Under Mac.OS.X (Macintosh Operating System 10): Safari and Mozilla Firefox
- Under Windows: Mozilla Firefox 25, Internet Explorer 9 and Chrome 30
You will find the following browsing components on all pages of the website:
- the SPIE logo to go back to the homepage
- the main menu, with links to access the main contents of the website structured into a hierarchy of sections
- the 'breadcrumb trail' shows you which page you are on, and helps you to switch quickly to a higher browsing level. It is displayed just before the start of the page content
- shortcut links (go to menu, go to content, etc.) are particularly useful for visually impaired users, since they provide direct access to the editorial space of each page
- the search engine is available on every page and provides the facility to search the entire website. The search results list the website pages containing the terms searched for
- the site map provides an overall graphic representation of all website sections and subsections. It is available in the form of a link at the bottom of every page
- priority links at the bottom of each page: Accessibility, Contact, Site Map and Legal information
- keyboard browsing: use the 'up' and 'down' arrows to scroll, the 'Tab' key to switch from link to link, and the 'Enter' key to follow an active link.
Small font sizes can make it difficult for some users to browse the Internet. This website has been designed so that the font size can be adjusted easily using the options offered by individual browsers:
- Internet Explorer: Tap or click 'View', and then tap or click 'Text size'
- Mozilla Firefox: Click 'View', then go to 'Zoom' and select 'Zoom Text Only'
- Safari: Click 'View' and choose 'Make Text Bigger' or 'Make Text Smaller'
If you use a wheel mouse, most browsers can make font sizes bigger by using the wheel in combination with a keyboard key:
- Windows: Ctrl + mouse wheel
- Mac: Apple + mouse wheel
You may find that some of the downloadable PDF files offered on this website have no directly associated accessible version. To read PDF files, you can download Acrobat Reader.
Alternatively, you can convert PDFs to standard HTML format using the Adobe online converter; just copy the address of the PDF file link and paste it in into the field provided in the Adobe online converter.
Viewing media using an accessible player
Some video content can be viewed using the Youtube video player.
A text transcription of video content is also available in a link just below the player.
Lastly, a link to the video on YouTube allows those whose device cannot display video within the SPIE website to access a dedicated video channel.
