Below are a few links to show what I have been researching so far:
Unfortunately I found this link cumbersome to deal with, but I did find some appropriate information to do with some of my initial ideas.
This is the technology used in cars to alert them if another vehicle is in their blind spot, it is called a Blind Spot Monitor and could be very appropriate for a variety of my ideas.
I also researched the above link but I found it inappropriate for my need.
The above link is to a wikipedia page about a wired glove that is worn by a user to control a computer. This would be very appropriate to one of my ideas in particular, the virtual glove for a blind person to use while on the computer to feel what is on screen.
