The Physically Disabled and Computers

Now... this is actually my homework for ICT, to find out how the physically disabled people can use computers, but I actually find this quite interesting as well.
I do wonder sometimes how I would manage without my senses, and on top of that without my computer. So the research I had found out about this is quite enlightening. I found out that...

- there are softwares made for the physically and mentally disabled, and that they will remove all barriers of disability, depending on the disability
- There is such a device called "The Tongue Drive System" where a small magnet is implanted in the users tongue, whom then has to movie his tongue to move the cursor around, as the tongue is directly connceted to the brain by a nerve, whereas all other parts of the body are connected to the brain through the spinal cord.
- The cursor can me moved by trackballs and foot pedals instead of the usual mouse
- There are joysticks that control the cursor on screen in the same way a mouse does
- There is the obvious touch screen that allows us to interact with the computer by touching the screen, although this method is used throughout the world by people with no disabilities
- Keyboards that have larger or smaller keys, or one that can be used with only one hand
- There are reading machines, that read the information on screen out loud, this is usually for the visually impaired
- There is the well known "Braille Technology" that writes the text into embossed Braille output. The embosser also lets you access your email, the internet and audio-streaming and many more

There is new technology coming out every day for the Physically disabled, and this allows them the use of computers just like everyone else.
The more advanced and usually more expensive, use infrared beams, ultrasound, eye movements, brain waves etc., to guide the cursor on screen without the use of hands.

This gives me a little bit of hope, that I would still be able to use my computer if something happened to me :-)

Homework- CHECK.
