2.1 Structure

Computers rely on structural integrity to process maths:

• PDF, print, handwriting and E-books using images of maths cannot be processed
  • They are inaccessible and inflexible on, for instance, small screen devices. They are lossy formats for maths!
• Word, HTML based formats and EPub3 have structural integrity for maths and are accessible to many assistive technologies (AT)
• But not all AT can access maths all formats - right now we probably need to produce as much choice as possible
• PowerPoint 365 is theoretically accessible but most AT won’t work with it yet and it can’t be transformed
• Using AT effectively for maths requires authors to produce accessible materials
