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 instead of hearing aids to overcome problems of background noise and distance from the speaker • FM System • Infra-red System • Personal Amplifier

Telecommunications • Fax machine • Wireless Pagers / PDAs • Text messaging • CapTel • Video Telephone • Video Relay

Computers • Computer Aided Real-time Translation • Video Telephone • Television • Telecaption Decoders • Decoder Chips

Assistive Listening Devices

How Video Relay Works

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

Hearing ear dog Increase daily living functions, social interactions and communications

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

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 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.

Device for recreations • TV audio description

Summary • AT for hearing impairments • AT for Visual impairments • Augmentation vs. replacement
