Available interfaces for the disabled

A keyboard for one hand!

It may be difficult for certain disabled users to use computers as they are, therefore interfaces have been developed to meet their needs. These include:
- Voice recognition: this can be a software and a hardware as programs can be bought that convert speech into text.
- Braille printers: this may be used by one who is blind it enables them to read text on a piece of paper.
- Speech: the opposite of voice recognition, this enables users to, for example, hear what they are typing.
- Keyboards with larger keys: this makes it easier for certain users to type
- On screen keyboards: enables users with physical disabilities to type more easily
- Reading pens enable users to read text from a piece of paper, this could help the blind.
- Joysticks could help certain physically disabled people 
- Touch screens can act as a mouse this may be easier to use than a conventional mouse. 


These technologies help the disabled in a big way, they are used in schools, workstations and at home everyday. Some of them are quite cool too like the one handed keyboard^^
