"AT" stands for "Assistive Technology," which refers to devices or software designed to help individuals with disabilities perform tasks that might otherwise be difficult or impossible. This technology can range from simple tools, like magnifying glasses, to advanced systems, such as speech recognition software. The goal of AT is to enhance the quality of life and promote independence for users. Examples of AT include screen readers for visually impaired users, hearing aids for those with hearing loss, and communication devices for individuals with speech difficulties. These tools are tailored to meet the specific needs of users, enabling them to engage more fully in daily activities and society.
