Students who are hard of hearing or deaf often cannot hear the beep or auditory alert a computer gives, but many computers now give visual cues, icons, or captions. Example: A flashing tool bar.
Students are are visually impaired often need a higher visual contrast and large font. Universal Access (Mac) or Ease of Access (Windows) makes this really easy to use a high contrast color scheme. The best options are a black background with white font or a white background with black font. Images and mouse pointers can also be enlarged. Blind students often rely on voiced feedback, narrator, or VoiceOver to read to them.
This is a video about how VoiceOver works for the iPhone.
In the next blog, I will cover the major types of keyboards and the students that benefit for them.
