What’s actually slowing this PC down?

Assistive technology includes products and services that help people maintain or improve functioning in areas such as vision, hearing, mobility, communication, cognition, and self-care. It ranges from wheelchairs and hearing aids to screen readers, speech recognition, and captions. The right choice depends on what a person wants to do, their environment, and whether the product can be fitted, learned, maintained, and supported.
What assistive technology means
The World Health Organization (WHO) defines assistive technology as an umbrella term for assistive products and the systems and services related to them. An assistive product can support everyday activities, communication, access to information, or independence. It may be physical, digital, or part of a broader service.
Assistive technology is not limited to products marketed specifically for disabled people. A phone’s built-in magnification, speech recognition, or captions can serve an assistive purpose. Conversely, buying a device does not always solve an access need: assessment, fitting, instruction, maintenance, and other services may be necessary.
How many people need assistive technology?
WHO’s 2024 estimates describe a global need, not a count for any one country. They also show why availability and access matter alongside product design.

Common types of assistive technology
Mobility and positioning
Wheelchairs, walkers, and white canes can support movement and navigation. Seating and positioning products may also be part of a mobility setup. For a white cane, suitability depends on factors including length and tip style, as well as the user’s needs and environment. Instruction in orientation and mobility can be important to using it effectively; a general product listing cannot determine the right cane or replace that instruction.
Vision and information access
Spectacles and magnification can support vision tasks. For digital information, screen readers can speak interface and page content, while braille displays provide tactile output. These tools work best when digital content and controls are structured so they can be identified and operated without relying only on sight.

Hearing and communication
Hearing aids and assistive listening products can help with hearing access. Captions display spoken content as text, while speech-recognition tools can turn speech into text or support voice-based input. Whether a particular tool helps depends on the listening or communication setting and the person’s requirements.
Cognition and self-care
Memory supports, time-management software, and environmental adaptations can help with planning, remembering tasks, and managing everyday activities. The useful setup is the one that fits a person’s routines and surroundings, rather than one with the longest feature list.

Alternative input and digital controls
Voice input, additional navigation methods, and other content transformations can make digital services easier to use for people who cannot rely on standard keyboard, mouse, or touch interaction. A tool’s compatibility with the person’s device, applications, and preferred way of working is central to whether it helps.
How screen readers, captions, and accessibility standards fit together
Assistive technology helps a person access or use a product; accessibility is a property of the content, service, or environment they are trying to use. A screen reader can speak page content, for example, but it cannot make missing labels or poorly structured content meaningful. Captions can expose speech as text, but they do not by themselves make every part of a video accessible. Effective access depends on both the tool and the thing it is used with.

WCAG 2.1
The World Wide Web Consortium (W3C) describes WCAG 2.1 as technology-neutral guidance with testable success criteria for web content on desktop, laptop, kiosk, and mobile devices. The W3C Recommendation is dated 6 May 2025. Its scope addresses needs including blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and some learning or cognitive limitations. W3C notes that assistive-technology functions can include synthesized speech, magnification, voice input, additional navigation, and content transformations.
WCAG 3.0
WCAG 3.0 is a W3C Working Draft dated 26 February 2026, not a final conformance standard. Its proposed scope is broader than web content alone, encompassing applications, streaming, virtual and augmented reality, and related user agents, authoring tools, and testing tools. It uses outcome-oriented approaches. Because it remains a draft, organizations should not present it as a finished standard or substitute it for applicable requirements.

Choosing assistive technology for a real need
Start with the task a person wants to accomplish, not a product category or headline feature. A useful decision considers the person, where and how the product will be used, and the support available after purchase or provision.
- Functional goal: Identify the activity or barrier the person wants to address.
- Independence and safety: Consider whether the option supports the desired level of independence and can be used safely in the relevant setting.
- Compatibility: Check fit with the person’s other devices, software, home or work environment, and existing assistive products.
- Training and support: Establish what instruction, fitting, professional support, or practice may be needed.
- Durability and upkeep: Consider portability, repairability, maintenance, replacement, and expected use.
- Total cost and funding: Look beyond purchase price to fitting, accessories, repairs, replacement, and possible funding or reimbursement.
- Privacy: For digital tools, understand what information is collected, processed, or shared and how the tool handles it.
Do not rank options on price or feature count alone. An option that is technically capable but incompatible with a person’s setup, difficult to maintain, or unsupported locally may be less useful than a simpler, well-supported alternative.
A practical provision process
- Define the goal. Describe the activity the person wants to do and what currently prevents or complicates it.
- Involve the person who will use it. Include the user in decisions and, where appropriate, involve family or others who support daily use.
- Assess the context. Check the physical environment, devices, software, compatibility needs, and relevant safety considerations.
- Select and fit the product. Choose an option suited to the goal and arrange fitting or configuration where needed.
- Provide instruction. Make sure the user knows how to use the product and where to get further help.
- Plan upkeep. Identify maintenance, repairs, and replacement needs before they interrupt use.
- Review the outcome. Check whether the product is helping with the intended activity and whether the person’s needs or circumstances have changed.
Why access remains uneven
WHO identifies several barriers to access: high costs and limited financing; products that are physically unavailable or come in an inadequate range; procurement difficulties; shortages in workforce capacity; limited awareness; fragmented services; and policy gaps. Even in high-income systems, products may be rationed or excluded from health and welfare schemes, leaving people to pay out of pocket. Availability of a product is therefore not the same as access to a product that is appropriate, fitted, and supported.
Are websites legally required to be accessible?
Legal obligations depend on jurisdiction, the type of organization, the applicable rule, and its implementation dates. In the United States, the Department of Justice published a fact sheet on 8 March 2024 about its Title II web and mobile-app rule, which applies to state and local government public entities; the final rule appeared in the Federal Register on 24 April 2024. The rule’s applicability, technical requirements, and compliance dates depend on the entity and the rule’s provisions. This does not establish one identical deadline for every private website. Organizations should check the official rule and obtain qualified advice about their own obligations.
