ATP EXAM RESNA INTERVENTION
STRATEGIES. EXAM 2025 QUESTIONS
AND ANSWERS
Mountability - ANS Refers to the attachment of the interface to the client, a wheelchair or a
work surface
Physical properties - ANS Describe the force the interface applies to the client and the force
the client needs to apply to the interface, as well as the size, weight, texture, and hardness of
the interface
Feedback - ANS Refers to the assistive device's responses to the client's action; expressed in
terms of magnitude, type of and orgin
Human/ technology interface - ANS Part of an assistive device with which the client interacts
Direct selection method - ANS The user chooses the input source directly at any time;
requires more physical skill
Indirect selection input - ANS Which selection input requires more cognitive, visual, and
perceptual skills
Indirect selection - ANS User must complete intermediate steps in order to make a selection;
Used when there are more inputs needed than the user can physically control

, The processor - ANS Part of the assistive device that provides a link between the human/
technology interface and other components
Commands - ANS Basic information needed to operate device; ex: joystick forward,
backward
Control parameters - ANS Optional parts of the assistive device ; allow client to modify and
adjust the system: ex: set up power WC speed
Activity output; characteristics are magnitude, precision and flexibility - ANS Refers the the
activity the system does for the client; 3 characteristics
Magnitude: extent of output (vol of speech system)
Precision: measures how accurately the system performs the activity
Flexibility: means the output is useful in multiple contexts - ANS What are magnitude,
precision and flexibility in relation to the activity output?
Environmental interface (ex: microphone, camera); 2 characteristics: range and threshold -
ANS Refers the the part of the assistive device that takes in information from the world; 2
characteristics
Range: measures size range of a discernible signal
Threshold: refers to the smallest possible signal size that is still detectable - ANS Define the 2
characteristics of environmental interface: range and threshold
Physical construction - ANS What characteristics of an assistive device are mountability,
portability, and packaging
Mountability - ANS Refers to the location where an assistive device is located
