Hearing and vision impairments
Hearing impairments Harding of hearing Loss of hearing
Vision impairments Visual field, contrast and color, light,
acuity Blind
Basic solutions for sensory impairment
Augmentation Microphone for hearing augmentation Magnifier for visual augmentation
Replacement Hearing problems
Visual and tactile as replacement Visual problems Hearing and tactile as replacement
AT in hearing impairments Alerting Devices and alarm
Visual Tactual Auditory
Amplification (hearing aids) Behind-The-Ear In-The-Ear Canal Aid Completely-In-the-Canal (CIC)
Assistive Listening Electronic devices used along with or instea
d of hearing aids to overcome problems of background noise and distance from the speaker

How Video Relay Works
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
Cochlear Implant
Hearing ear dog
Increase daily living functions, social interactions and communications
AT for visual impairments
Non-technical Solutions Organisation of the home (inside and outsid
e) 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
Personal assistive devices Devices for improving vision
Field expenders Telescope Eye glasses
Devices for reading Typoscope Enlarging photocopiers Magnifiers
PC with speech synthesis CCTV: Closed circuit TV –
Electronic reading machines Optical character reade
rs (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.
