What are the three components of the AT System?

The correct answer identifies the three essential components that form the foundation of an assistive technology (AT) system. It emphasizes the relationship between an individual with a disability, the activities they need to perform, and the assistive device that facilitates these activities.

A person with a disability is central to the AT system because they are the one who utilizes the assistive technology to enhance their functional capabilities and engage in daily activities. The activities component refers to the specific tasks or goals the individual is trying to achieve, which can include anything from mobility and communication to work-related tasks. Lastly, the assistive device is the technology or equipment that is specifically designed or adapted to meet the individual's needs, helping them to perform these activities more independently and effectively.

This holistic view captures how assistive technology is not merely about the device itself, but rather about how that device interacts with the individual's capabilities and needs related to tasks they wish to accomplish. Understanding this relationship is crucial for professionals working in the field of assistive technology, as it informs the selection and implementation of effective solutions tailored to the user’s unique circumstances.
