This section will explore various types of technology that can be used to control the computer without using the traditional keyboard and mouse.
Alternative keyboard layouts and other enhancements allow people who experience difficulty with conventional keyboard designs to use computers.
Alternative pointing devices, trackballs and keypads are used to replace the mouse.
Personal Digital Assistants (PDA) are portable computers that are designed to act as organizers, note takers and/or communication devices.
An onscreen keyboard generally appears on the same display used for programs and will remain permanently visible. The keyboard can then be accessed using pointer devices. In the simplest sense a pointer is a standard mouse, but through the use of alternative pointer devices or switches a large number of disabilities can be accommodated.
Switches are a common solution for users with mobility disabilities who need to use computers or other electronic devices, but have difficulty with the physical interface based on its’ design.
Voice Recognition allows a user to use their voice instead of typing on the keyboard. Voice recognition may be used to dictate text into the computer or to give commands to the computer (such as opening application programs, pulling down menus, or saving work).
