According to Roblyer and Doering (2012), in the USA, federal law recognizes several types of disabilities: deaf, hard of hearing, mental retardation, multi-handicapped, orthopedically impaired, seriously emotionally disturbed, special learning disabilities, speech impaired, or visually handicapped.

For those who are vision impaired- you have the ability to turn on a narrator who reads aloud any text on the screen, or hear descriptions of what’s happening in videos, turn off all unnecessary animations, make the cursor larger, increase the contrast on the screen, remove background images, audible clicks on the keyboard or zoom in so that smaller items may be seen larger.
For those with physical impairments- you can use an on-screen keyboard so that you can type with the mouse or joystick, speak into a microphone to control the computer, open programs and dictate text, set up the mouse so that the user only has to hover over an area for it to open rather than requiring the user to click and keyboard shortcuts so that it limits how much typing is required.
For those with attention deficit disorders- you are able to have the narrator read aloud to you, remove the distracting background images, turn on sticky keys , toggle keys and filter keys, adjust the time limits and flashing visuals, make it easier to manage windows by preventing windows form being automatically arranged when moved to the edge of the screen.
For those with hearing impairments- you may turn on visual notifications for sounds or have text captions for spoken dialog.
