Cochlear implant
Cochlear Implant

  • A surgically implanted multi-channel electrode housed within the cochlea

  • For clients with severe to profound bilateral hearing loss with poor speech understanding

  • Extensive aural rehabilitation may be needed after surgery

At for visual impairments
AT for visual impairments

  • Non-technical Solutions

    • Organisation of the home (inside and outside)

    • Improved natural and artificial lighting

    • Improved use of colour contrasts

    • Elimination of hazards

    • Organising and labelling items


  • Accessible printed material

    • Large print

    • Braille and Moon

      • Braille uses a raised six-dot system to

        represent letters and Moon uses a raised graphical representation of letters

    • Talking books and magazines

    • Electronic books and newspapers





  • Electronic reading machines

    • Optical character readers (OCRs) scan and translate printed text into a text file that can be read by a built-in speech synthesiser or used on a computer


  • Devices for writing

    • Writing on paper

    • Writing (typing) by computer

    • Writing in Braille

    • Making audio notes and letters


  • Devices for mobility /walking

    • Canes and walking sticks

    • More high-tech aids have recently begun to be developed such as satellitebased orientation and navigation systems to support blind pedestrians.
