Professional Practice in Assistive Technology.

1. Sensory Function As Related To
Assistive Technology Use

2. Sensory Functions
• Vision
• Hearing
• Taste
• Smell
• Touch
• Proprioceptive
• Vestibular

3. Examples

4. Perceptual Function As Related To
Assistive Technology Use
• Blindness is the condition of lacking visual
perception due to physiological or
neurological factors

5. Examples of AT
• Speech Recognition software
• Screen Reading Software
• Refreshable Braille Displays

6. Cognitive Function and Development
As Related To Assistive Technology Use
• Cognitive Function and Development As Related To Assistive Technology Use
• In cognitive function it is changes that occur in a child arise from both
environment mental influences and a biological maturation. This is the
performance that most often affects the design and implementation of assistive
technology systems. The assistive technology often provides a function for which
the person has no experience base. The use of a wheelchair the disable human
operator my have never been responsible for his or her own mobility and my not
have experience in making the required decisions.

7. Psychosocial Function As Related To
Assistive Technology Use
• Psychosocial Function As Related To Assistive Technology Use
• This assistive technology is composed of both intrinsic and extrinsic
factors. The intrinsic characteristic of an individual is not easy for the
influence of the person’s social environment. The fundamental is to
regulate behavior to maintain mental health and maximize each person
productive contributions in valued roles and society. The six factors that
determine motivation are elicitors of behavior, symbols, beliefs and
perceptions, cultural norms and expectations, intrinsic motivation and
history of experience.

8. Motor Control As Related To Assistive
Technology Use
• Motor control as related to assistive technology can refer to
tall the central processing functions that lead to planned
and coordinated motor outputs. In order to perform control
task the human operator must be able to locate a target,
plan a movement to that target and produce a desired
action one the target is reached. A movement is repeated
many times, motor learning takes place and both the speed
and the accuracy of the movement improves. The motor
learning is made possible by engrams
• (Preprogrammed patterns of centrally represented
muscular activity). The control devices are aimed through
movement carried out by the user. Many human factors
engineers often use speed and accuracy to measure motor
performance.

9. Effector Function As Related To
Assistive Technology Use
• The human operator controls the assistive technology
through the various effectors and the effectors enable
manipulation of the environment in a variety of ways.
There are a variety of ways of accomplishing the same and
effector function cannot be interpreted from the point of
view of a nondisabled person. The effector provides the
major outputs that are underline both stabilization and
control. The control can include hand or fingers, arm, head,
eye, leg, foot and respiration and phonation. There are two
primary factors that are use for automatic movements and
muscle tone. Primitive reflexes, which are characterized by
immediate and automatic movement, performed at a
subconscious. Muscle tone is defined as a resistance to
stretch provided by neural activity of muscle and joints.
