Making Video Figures Accessible
We strongly encourage authors to make their videos (teaser, presentation) accessible by adding text captions to transcribe the audio (to make videos accessible to people who are deaf or hard of hearing) and audio narration to describe the presented visuals (to make videos accessible to people who are blind or low vision). Authors can refer to the guidelines of video captions and descriptions for more information.
Making Presentations Accessible
We strongly encourage authors to make their (live, recorded) presentations accessible to diverse audiences. For instance, designing slides with high contrast texts or describing slides thoroughly (to make presentations accessible to people who are blind or low vision). We also encourage authors to release their accessible slides (by following the above process on making PDF accessible). Authors can refer to the Accessible Presentation Guide about how to make your presentation accessible.
Making PDFs accessible
We strongly encourage you to add accessibility to the PDF using Acrobat Pro DC and the steps below. If you do not have access to Acrobat Pro, and you need assistance with accessibility, please contact the UIST 2025 Accessibility Chairs at accessibility2025@uist.org.
'Undo' is not well supported in Acrobat Pro, so save often!
- Set tab order. Setting the tab order is necessary so that a keyboard user can use the tab key to navigate through the document.
- Select the Page Thumbnails icon on the left to show thumbnail images for each page (or, in the 'View' menu, select 'Show/Hide > Navigation Panes > Page Thumbnails').
- Select all pages with Control-A (Windows) or Command-A (Mac).
- Right-click and select 'Page Properties'.
- In the popup window, select 'Use Document Structure' on the 'Tab Order' tab.
- Click ‘OK’.
- Open the accessibility tools.
- From the View menu, select Tools > Accessibility.
- The accessibility tools panel opens on the right of the screen.
- Add document tags. The PDF file must be "tagged" with metadata about the document structure and text. For a small minority of pdfs, adding tags may cause visual elements to move or disappear.
- Save the document in case adding tags introduces visual issues.
- Select 'Autotag Document' from the accessibility tools panel.
- An 'Add Tags Report' will appear on the left when tagging has been completed.
- Important: Visually scan the entire paper to make sure the visual appearance has not changed. If items have moved or disappeared, stop here and contact the accessibility chairs for help.
- Check tagging.
- Select 'Reading order' from the accessibility tools panel.
- The Reading Order panel appears, and the paper is visually marked up to show the content detected on each page and the order it will be read.
-
Skim through the pages of the paper.
- Make sure the reading order of the text is correct. If it’s not, you can use the reading order tool to identify the text, and the order panel to reorder the items on each page.
- Mark the paper title as 'Heading 1', main headings as 'Heading 2', second level headings as 'Heading 3', and so on.
- Make sure all the figures have been marked as figures. If the caption is not included in the figure, drag over the figure and the caption and use the 'Figure/Caption' option in the 'Reading Order' panel. If the marked figure includes non-figure content, as in the example above, select the extra content and mark it as text/formula/table/etc using the options on the 'Reading Order' panel. In the example above, after marking the text in this way, the border of the figure is updated.Updated page markup for figure differs from the previous screenshot in that the text below the figure is no longer within the figure's border.
- The border of the figure may appear larger than the figure itself. This is fine so long as the other items on the page are marked appropriately, as with the second column of text in the example.
- Make sure all tables are identified as tables. See Step 7 below for more details on proper table markup.
- Close the 'Reading Order' panel.
- Add figure descriptions (alternative text) to all figures. The alt-text should contain the equivalent information to the image itself, so that the content is accessible to readers and reviewers who cannot see the image. It should not be the same as captions, which provide additional information to the image but do not supplement it.
- Select "Set Alternate Text" from the accessibility tools panel. This option will walk you through each image detected in the paper and ask you to provide alternative text.
- If the highlighted figure is actually a running header or footer, or anything else that isn’t an actual figure, glyph or meaningful image in the paper, click the 'Decorative figure' checkbox. CHECK THE CONTENT DID NOT DISAPPEAR!
- If the highlighted figure is a real figure, copy the description from your source into the 'Alternate text' field. See the SIGACCESS Guide to Describing Figures for details on how to write good figure descriptions.
- After working through all the figures, select 'Save & Close'.
- Mark up tables. For every table in the paper, follow these steps:
- Right-click on the table and select 'Table Editor' from the context menu. If there is no 'Table Editor' option, then open up the 'Reading Order' accessibility tool. Make sure the table is marked up as a table, then select the table and choose 'Table Editor' in the 'Reading Order' tool.
- If you see the message 'Unknown table structure encountered', then your table has not been properly tagged. This happens most often for tables without visible lines separating the cells, or more complex tables.
- Fixing table tagging takes time and a willingness to dig into the tag structure, where there is no way to undo mistakes. The tagging can be manually corrected by using the 'Reading Order' tool to mark up each individual cell, then using the Tags panel to build these table cells into a properly structured table. Refer to Adobe's guidance on table repair for more information.
- If the table is properly tagged, make sure that the header cells are marked as 'TH' and the data cells are marked as 'TD'. The type of a cell can be changed by editing the properties for that cell, available in the context menu. If the cell is a header cell, indicate the scope – whether it is a header for the row, column, or both.
- Set title and language. Select File > Properties from the menu. Select the Description tab. Fill the Title field with the document title. Next, select the Initial View tab. In the Show dropdown, select Document Title. Next, select the Advanced tab. In the Reading Options section, select English from the Language dropdown menu.
- Check accessibility. Run the accessibility checker to see if there are further accessibility issues in your document. Select 'Full Check' from the accessibility tools panel. The checker produces a report that provides help with fixing many accessibility problems. Saving the PDF in Acrobat should save the relevant accessibility data by default. No extra steps are necessary.
