With some minor adjustments you can ensure that you do not exclude this target group and that your client can welcome more people to his website. It is good to make your websites future proof in that regard. More than 350,000 Dutch people have a visual handicap and with the aging population this number will only increase further. It is not very user-friendly to have to click through to the results again on the "search results" page. You could possibly also build in a skip link, but that is not recommended. Therefore, try to ensure that they appear after the search results in the html. This often means that the screen reader first reads the filters before reading the actual search results. Visually you will often find these filters to the left, right or above the results. Use a physical table (you can generate it with this tool, for example) so that screen readers can also read it.Ī search function is very useful and nowadays we also build filters in here, but this does not always work well for the visually impaired. A pity, because a visually impaired person cannot see this information that way. Tables are also often placed as images on a website. A screen reader will read the title of the image and that does not really tempt you to purchase this jacket in this case. However, the image is called, for example, “JS2018col2.jpg”, if there is no descriptive alt text here, such as, for example, “blue winter coat with side pockets”, it is confusing. You often see confusing alt texts at online stores. So don't put nonsense here, but be descriptive, what do you see? In any case, make sure that the alt text does not cause confusion when you read the rest of the text.
For SEO it is important that you have good alt text, but that also applies to the visually impaired. Keep alt texts meaningful and put decorative images in the style sheetsĭecorative images actually belong in the style sheets anyway, but sometimes you can't help but put it in the html.
Not only does Google use that to scan your page, screen reading software does that too! You probably already do this for your SEO, but if not, now is the time to really put the most important words up front in titles and links. Put the most important words in front of links and titles
Therefore, make sure that the subject of a page is clear quickly, after which you can show all your extra features. Often they have to go through a lot of crap before they know what this page is about. The reading software scans a page from top to bottom. But for the visually handicapped this is not so much fun at all. Present the most important information as soon as possibleĮxtra features, beautiful animations, search bars and related articles are of course great fun for the click-through value on your website. This means that they often really have to have the page read to find out what the content of the page is. If there is all unrelated information there, it is very difficult for the visually impaired to scan the page. In order to scan pages, this software first reads out the h1, h2 and h3. An ordinary user will not see this, but screen readers will immediately pick it up. We often come across it, related links are shown as h3 headlines. Only use the H2 and H3 headings for paragraphs and sections If main menu items are just headings for the submenus, keyboard navigation will not work. You can easily solve this by using device independent event handlers (onFocus, onBlur, onSelect, etc.) or by adding extra keyboard event handlers (onKeyDown, onKeyUp, onKeyPress, etc.)ĭon't forget to do this in the menus and make sure that the main menu items actually link to something. These are mouse dependent and users cannot proceed without using the mouse. You stop spam, but also often visually handicapped! Most of the problems are in the use of JavaScript events such as 'onMouseOver' and 'onClick'. The most important thing for you as a developer? The entire website, including menus and forms, must be controllable with the keyboard. They can't see the mouse pointer! Often a choice is made for complete control with the keyboard, a joystick or voice control. The visually impaired do not use a mouse. Make sure that the entire website can be operated with a keyboard Visually impaired people often also use enlargement software or a high contrast value to make pages easier to read. In addition, a Braille line is often used on the computer so that they can feel what is on the screen. First, they use a screen reader, which is software that reads what is on the screen. They often use a combination of techniques. Now that you know that visually impaired people can also be found online, it is not difficult to imagine that they do this very differently from us. How do the visually impaired use the internet?
