Short Description
Standard keyboards have been developed for the average user. A range of alternative keyboards are available for computers. They are considered when there is an identified need for:
* increased accuracy
* improved comfort
* accommodating limited range of movement
* automation of specific functions
* using an alternative body part (eg. fist or foot) to operate a device.
More Details
Some keyboards have been designed for a specific purpose (eg. one handed). Others can be used in a variety of ways depending on individual needs.
Features to consider:
* Type of feedback the keyboard provides (tactile, auditory, visual).
* Pressure required: people with limited strength or pain may require very sensitive keyboards. Those with inaccurate movements (eg. tremor) may benefit from a less sensitive or time delayed keyboard to avoid accidental activation.
* Mounting, positioning and portability: consider the size and weight of the keyboard to achieve the desired location and flexibility of the system.
* Ergonomic factors: consider angle of the wrists and elbows, the position of the shoulders and head when using the keyboard. Accessories such as wristrests may be necessary to improve comfort and access.
* Range of movement: it is important to match a keyboard to the available range of movement over which a client has control.
Consultation
In some situations it may be advisable to consult an expert in the area of technology for people with disabilities. The Computer Assistive Technology Services (CATS) is a division of Northcott and located in North Parramatta. They also travel extensively through NSW. The Assistive Technology Service of Cerebral Palsy Alliance is located in Allambie Heights.

Standards
Some assistive technology needs to meet Australian or other standards. Standards may relate to materials, manufacturing and installation. Products that meet Australian or international standards will have written certification. To find out if a product meets Australian Standards ask the supplier to show you the certificate.
