Conditions such as arthritis, repetitive strain injury and carpal tunnel syndrome can make actions like typing or moving a mouse painful. However there are assistive technology solutions that aim to ease the discomfort caused by such conditions. Many people prefer to use ergonomic mouse devices instead of traditional computer mouse devices as they are held in a more natural way, limiting the strain on a person's wrist. Of course the act of typing can become extremely difficult if a person finds the movement of their fingers or wrist painful, but there are also ways of overcoming this. The most popular solution would be to use a piece of speech recognition software such as Dragon. This software allows you to speak what you would like to be typed and the software recognises the words that are being spoken, converting them into text on the screen. It takes a little time to allow the software to adjust to your voice, but it learns your individual vocal range quickly, meaning that once it has adjusted you no longer need to type.
