Digital Accessibility: MS Powerpoint Alt Text (2)

-

Tip: To write a good alt text, make sure to convey the content and the purpose of the image in a concise and unambiguous manner. The alt text shouldn’t be longer than a short sentence or two—most of the time a few thoughtfully selected words will do. Do not repeat the surrounding textual content as alt text or use phrases referring to images, such as, "a graphic of" or "an image of."


Add alt text to images

PowerPoint does not automatically generate alt texts for drawn images, such as diagrams or icons. If you want to add an image that is an icon, screenshot, or other image that is not a photograph, you need to add the alt texts manually.


Do one of the following:


Option 1: Right-click an image and select Edit Alt Text



Option 2: Select an image. Select Format > Alt Text


The Alt Text pane opens on the right side of the slide.


Type 1-2 sentences to describe the image and its context to someone who cannot see it. It is not necessary to say "this is an image of" in the description. The screen reader may already make this distinction. Rather, give a robust description of what is being pictured:




Tip: To spell check and correct a word you typed, just right-click the word and select from the suggested alternatives.

Digital Accessibility: MS Word Hyperlinks (5)

A URL ( uniform resource locator) or web address is a location on the web, such as  www.ndm.edu/nursing . For a screen reader user, a URL is problematic as the screen reader attempts to read out the full address one letter at a time. On longer web addresses, a screen reader can lose or skip some of a URL as it attempts to read it. The way to fix this is to make a natural language hyperlink such as the  MSN News Page . Two Rules of Thumb: Don't show the actual URL, and Do not write "click here." Instructions for Adding Hyperlinks in Word To add a hyperlink to your Microsoft Word document, do the following: Type a meaningful title for your hyperlink. Select the title text. On the Insert tab, in the Links group, select Hyperlink to open the "Insert Hyperlink" dialog box. (Alternatively, you may right-click the selected text.) With the Link to: Existing File or Web Page option selected, insert the link's full URL into the Address bo

Digital Accessibility: Saved as PDF

A more common type of PDF is one created in a different format and saved as a PDF. Perhaps you created a Microsoft Word handout and wanted to make it as available as possible to students. But to keep the formatting correct and not allow them to make any changes, you saved it as a PDF. The PDF is always less accessible than the original file. So, if you didn’t run the accessibility checker on your Word file and resolve any issues found then, the PDF will have those issues While PDFs are becoming easier to make accessible, the editing options are limited. My advice is that if you create the original file in another authoring tool (Word, PowerPoint, Etc) run accessibility checks in this tool and make your necessary changes there. It saves you quite a bit of work in Adobe Acrobat. that said, here's how to get the process started: Open the file in Acrobat Pro Click Tools Click Action Wizard Click Make Accessible After “making accessible,” Acrobat will want to run the ac

Digital Accessibility: MS Word Structure (3)

Structural Tips for Microsoft Word Headings and Lists provide the basis of good document structure. Layout, spacing, pagination, layout, and blank characters are also helpful structural considerations. Note: the the most frequent error in using the accessibility checker is four or more blank characters. This error occurs if someone hits the space, tab, or enter key more than three times. The solution is to use three or fewer blank spaces (tabs or hard returns). These often occur is because we use tabs or spaces to format our documents. There are ways to achieve certain looks which are accessible. Under the Home tab in your Word Ribbon, you have "Paragraph Tools" to help align columns of text and increase or decrease indentations. Under the "Layout Tab" you have several more options, such as: Columns Page and Line Breaks Increase and decrease indentation Using the built-in formatting tools make your finished product look more consistent w
