Introduction and Overview - Assistive Technology

Question # 2

What is meant by “low tech” and “high tech” assistive device? Give and example of each.

Low tech AT are devices or equipment that don't require much training, may be less expensive and do not have complex or mechanical features. 

Example: 

Large print text, Canes and walkers, handheld magnifiers 

High Tech AT refers to the most complex devices or equipment, that have digital or electronic components, may be computerized, will likely require training and effort to learn how to use and cost the most.

Example:

Power wheelchairs and Scooters, Digital hearing Aids

Question # 3

Distinguish between hard and soft technologyAnswer in your own words:

Hard technologies contain within them the processes and methods to achieve the ends for which they were designed. This brings efficiency, scalability, replicability, freedom from error and speed. 

Soft technologies are flexible, supporting creativity and change, because the gaps inside them have to be filled with processes constructed by people. They are needy and incomplete until people fill the holes. 

Question # 4

Give three examples of assistive technology appliances and three examples of assistive technology tools.

Appliances

Examples:

Key guards, Alphabet board, Electric feeder

Tools

Examples:

Joysticks, Sensory, Mobility, Enlarged keyboard

Question # 5

What is the difference between minimal and maximal assistive technology? Give and example of each. 

Assistive technologies are specified and designed to meet a continuum of needs. At one extreme are devices that provide some assistance or augment the individual's ability to perform a task.

Example:

Maximal, an individual with cerebral palsy may be able to speak, but on occasion his speech may be difficult to understand. In those instances the individual may clarify his speech using a letter board to spell out words not understood.

Minimal technologies generally augment rather than replace function. Classically, devices that augment have been termed orthoses or orthotic devices.

Question# 8

Distinguish between specific purpose and general purpose technologies

Generalpurpose assistive technologies include (1) positioning systems, (2) control interfaces, and (3) computers. These are classified as general purpose because they are used across a wide range of applications. 

Specific purpose assistive technologies facilitate performance in one unique application area. Examples include devices for communication, manual and powered wheelchairs, feeding devices, hearing aids, and mobility aids for persons with visual impairments.
