In short, yes. Assistive technology is a broader category incorporating devices, products, equipment and software to help people with disabilities by helping improve functional capability. Assistive devices may include walkers, wheelchairs, hearing aids, and speech recognition software. The main point is that these products are inclusive of both mainstream technology and those created specifically for the temporarily or permanently disabled or impaired.
Adaptive devices are a subcategory of assistive technology. These independent living aids encompass all items designed to make everyday activities efficient and self-care achievable. Examples of adaptive equipment are dressing aids, eating and drinking aids, or bathing and toileting aids.
