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)
- Headings or list items are not marked up as headings or lists on some pages (Criterion 1.3.1 Information and Relationships)
In order to resolve the above issues, we will continue to improve the flow of web page creation, various guidelines, and the accessibility confirmation system. We will also revise components as necessary.
Challenges with Non-Textual Content such as Images and video in Machine-Translated English Pages
- If an image contains text, the text will not be translated and only the alternate text will be translated into English, so there may be places where the alternate text does not function as well as the image (Success Criterion 1.1.1 Non-Text Content)
- 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, including the use of generative AI.
Issues found in the PDF file
- Files were identified that were not properly labeled with alternate text for images (Success Criterion 1.1.1 Non-Text Content)
- Some are not marked up or bookmarked, which can make it difficult for screen reader users to understand the content of the document (Criterion 1.3.1 Information and Relevance)
- Untitled Files Verified (Success Criterion - Page 2.4.2 Title)
- A file without a language setting was 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.
