Accessible names and labels are essential for eye-trackers, screen readers, and other assistive tech. HTML is interpretable by most assistive technologies, including eye-tracking systems, and helps to accurately identify on-page elements. When developing your content, use generic HTML wherever possible.

However, developers should understand the intent of the rule: When targets are close together, real-world users may be unable to navigate comfortably. For example, websites can provide users with a mechanism to change the CSS pixel size of each target or its spacing. WCAG outlines several exceptions for this guideline. Websites can address this barrier by conforming with WCAG 2.1 SC 2.5.8, “Pointer Target Spacing,” which reads:įor each target, there is an area with a width and height of at least 44 CSS pixels that includes it, and no other targets. “You need to allow as much space and size as possible when determining your placements to help the eye tracking user select those targets without accidentally selecting something else nearby.” “There are many ways to handle actionable target elements such as buttons, banners, and text links,” says Jaén Cantor, UX designer of Tobii Dynavox. However, small targets can still create barriers for users. Provide space between buttons, links, and other targetsĮye-tracking systems often have screen magnifiers, which enable users to activate links, drop-down menus, and other interactive targets. For each entry, we’ll also identify WCAG 2.1 Success Criteria (SC) that could help content creators prevent (and fix) accessibility barriers.įor expert guidance on this article, we reached out to two of the leading eye-tracking developers: Tobii Dynavox and Eyegaze, Inc. The Web Content Accessibility Guidelines (WCAG) provide the best framework for designing content that works for all users - including people with disabilities who use assistive technology.īelow, we’ll discuss a few design and development decisions that could impact people who use eye-tracking technology to access websites or mobile apps. However, all assistive technologies work more effectively on well-designed websites. When properly calibrated, eye trackers provide a comfortable, intuitive way to browse the internet. The technology addresses many of the challenges that people with disabilities encounter when using a mouse: Users are less likely to become fatigued or make accidental clicks. #Itracking tracking chip software#A camera tracks the reflections from the LED, and software processes eye movements.īy looking at specific parts of the screen, users can interact with on-screen keyboards, mouse simulators, and other input fields. The technology typically uses a low-powered infrared light-emitting diode (LED) to illuminate the user’s eye. Eye-tracking devices (also called eye trackers) are an assistive technology developed for people with mobility conditions, neurocognitive conditions, and other disabilities.
