Assistive Technology

Assistive Technology — devices, software, and services that help people with disabilities perceive, operate, communicate, and participate in learning and daily life. In AI in education, assistive technology spans screen readers, speech-to-text and text-to-speech, captioning, braille and tactile output, sign-language tools, and increasingly AI-powered accommodations that adapt content and interaction to individual needs.

Assistive technology is the concrete tool layer of Accessibility. Where accessibility is the design property of an environment (can everyone access it?), assistive technology is the specific equipment and software that individuals use to bridge access gaps. It is foundational to Special Education and Inclusive Learning — students with specific learning disabilities, visual or hearing impairments, and motor challenges rely on assistive tools to access the curriculum. In the U.S., the Assistive Technology Act (2004) and the Individuals with Disabilities Education Improvement Act (IDEA, 2004) provide the legal basis for providing these tools to students with disabilities.

Key research themes

AI is expanding assistive technology. Generative AI and LLMs are transforming assistive tools — LLM-based text simplification adapts reading level in Intelligent Tutoring, voice-first AI removes visual dependency for blind and low-vision learners, and AI-generated tactile graphs convert visual data to touchable output. Zhang et al. find AI-based interventions (robots, software, intelligent VR) yield a medium positive effect on the learning outcomes of students with disabilities (g = 0.588).

Policy and provision. Shin et al. document that U.S. AI policy documents largely fail to address assistive technology and accommodations for students with specific learning disabilities, calling for policy guidance grounded in the Assistive Technology Act and IDEA.

The limits of assistive tools. Assistive technology enables access but does not by itself ensure inclusive instruction or learner Agency. Critical research and the push for agentic roles for students with disabilities remind us that access must pair with meaningful participation.

Implications for practice

• Match the tool to the learner and task. Screen readers, captions, speech, and tactile output each address different barriers — choose based on the individual's needs and the content format.
• Leverage AI to lower the cost of assistive adaptations. AI can auto-caption, simplify text, and generate alternatives, but evaluate output quality for pedagogical accuracy.
• Ground provision in policy. Reference the Assistive Technology Act, IDEA, and WCAG when procuring or building AI tools.
