The main way that we create content in both work, education and leisure is by text.
It could be by using Microsoft Word or other applications such as PowerPoint, by adding content to social media sites like Facebook or Twitter or texting a friend using WhatsApp or Skype.
Most users do this by a standard QWERTY keyboard that has become a global standard. For users who may have print impairment or difficulty with spelling and grammar, most word processing packages have both a spell and grammar checker that will highlight possible errors automatically. For users with specific learning difficulties, such as dyslexia, there may be a need for more advanced options such as highlighting homophones, words that sound the same but are spelled differently. It is also helpful to use a text to speech programme to get the words you have typed read back to you. The advantage of this is that when you read your own text, in general, you tend to read what you intended to type. When a third-party application reads your text out loud, any errors will be more obvious!
Many users benefit from the use of predictive text applications. Most people are familiar with these on mobile phones but there are some useful packages available for the PC. One free to use package is DiCom. In this case suggested complete words appear in a small window as you type.
The Communication page has details of how scanning applications can be used for communication. These packages can also be used for writing, as well as control of both the PC and other environmental options.
There are other very specialised applications to address specific difficulties. Dasher is a word processing application that is designed for those who cannot use a keyboard. It works on continuous pointing by either the mouse or a mouse substitute such as eye gaze, head pointer or touchscreen.
