Week 7 Activity 4.1 - Researching Assistive Technology Tools

I chose the following technologies for further research from the TechDis Presentation 'Assistive Technology Overview' and evaluated its main features, the cost of the technology and supplier training.

Talking Word Processors
  • Word processors that have a speech facility to enable users to hear the words and sentences as they are being typed. Some also read toolbars and menu’s. They may have a word bank facility to make suggestions.
  • Write:Outloud seems to be popular in the UK and can be purchased for between £31 - £71 depending on the number of licenses.
  • ‘Getting Started’ manual available online. Also found some third party tutorials. I didn’t find any formal training courses for Write: OUtloud.

Trackballs
