Disabilities & Assistive Technology
The Plan
• Overview
• Types of disabilities
• Technologies that address them
What you’ll get out of this
• Understanding of disabilities and how
they affect computer use
• Learn what technologies can be used to
get around these obstacles
• Can take this knowledge into
consideration when planning an online
course or website…
• …and when accommodating a disabled
student in a classroom course.
Types of disabilities
