Challenges identified by the study and directions for their resolution
As a result of the tests, we are aware of the following issues and will continue to work to resolve each of them.
Issues found in web pages (HTML)
- Web pages were identified where images were not properly labeled with alternative text (Success Criterion 1.1.1 Non-Text Content)
- Video content without subtitles, audio descriptions, or transcribed text was found (Success Criterion 1.2.2 Captions (prerecorded), 1.2.3 Audio descriptions or media alternative content (prerecorded), 1.2.5 Audio descriptions (prerecorded))
- Web pages were identified where headings or lists were not marked up as headings or lists (Criterion 1.3.1 Information and Relationships)
- Dashboards and video slides relied solely on color to provide information (Success Criterion 1.4.1, Use of Color)
- Some slides in the video were found to have insufficient contrast ratios between the text and background colors (Success Criterion 1.4.3 Contrast (minimum))
- A link was identified that could not be predicted from the link text or surrounding context (Criterion 2.4.4 Link Purpose (In Context))
In order to resolve the above issues, we will promptly check the accessibility of the website before and after updating it. We will also revise components as necessary.
Video content issues for English-language pages
- On a page that features YouTube video, Japanese characters in the channel name or video title are not interpreted by screen readers or other programs (Requirement 3.1.2, Partial Language)
In order to solve the above problems, we will consider countermeasures from both technical and operational aspects.
Issues found in the PDF file
- PDF files were identified that were not properly labeled with alternate text for images (Success Criterion 1.1.1 Non-Text Content)
- PDF files with unstructured headings, tables, and lists were identified (Criterion 1.3.1 Information and Relationships)
- PDF files that were not tagged and had no reading order set were verified (Success 1.3.2 Meaningful Order)
- Checked Untitled PDF Files (Success Criterion 2.4.2 Page Title)
- PDF Files Without Language Settings Identified (Success Criterion: Language on page 3.1.1)
Overview of accessibility by document type
Proceedings, minutes, and meeting materials
The lack of tagging, language settings, and file titles makes it difficult to use with screen readers.
Efforts to Improve Accessibility
- When publishing in PDF format, create proceedings, minutes, and meeting materials that can be read by a screen reader.
- If PDF is not necessary, prepare a web page.
- Further Efforts
- Add headings to help you understand a long passage of text more accurately and move through a document more easily
- In the case of a long document such as minutes of a meeting, a summary should be provided at the beginning of the document to facilitate understanding of the entire document.
Presentation material
- Lack of tagging, language settings, or file titles makes it difficult to use with screen readers
- You can't understand a given presentation with a verbal explanation just by adjusting the reading order.
- If there is too much information in one slide, it may be difficult to understand the content even if the readability is improved.
- Attached graphics used in different materials with no alternative text and no information that can be read by a screen reader
Efforts to Improve Accessibility
- Use text or a Web page as a alternative content for a slide
In order to solve these issues, we will continue to develop the flow and various guidelines for creating PDF documents and the accessibility confirmation system.
