From the first wheel chair in the 17th century to braille in the 19th century, hearing aids and the type writer in the 20th century to the invention of the Chromebook in the 21st century, assistive technology has adapted. The inventors and users of AT have done their best to grow, develop, and change with the resources, mindset and culture of an area to help the needs that the community has. We can see in this timeline that each invention serves a purpose and evolves (for example from functioning manually to automatically or electronically).
Let's have a walk down memory lane shall we...

Do any of these years surprise you? When have you noticed AT starting to be implemented in your classrooms or schools?
Can you think of anymore influential or "game changing" inventions? What do you think will be invented next? Are the possibilities of AT endless? If not, what do you believe are its limitations or barriers?
