Types of Selection Displays
|
Fixed
Dynamic Hybrid |
|
Fixed Display
|
Any device where the symbols are fixed in a specific location
|
|
Dynamic display
|
Computer screen displays that automatically change when the individual selects a set
|
|
Hybrid Displays
|
Electronic fixed displays with a dynamic component such as indicator lights to tell individual which items are available for selection
|
|
Selection Techniques
|
Direct Selection
Indirect Selection |
|
Direct Selection
|
Indicates the desired item directly from the device
Physical Pressure, Physical contact Pointing, eye gaze |
|
Indirect Selection
|
Scanning - for those individuals who are unable to directly select from the selection set - due to lack of motor control
|
|
Scanning Patterns
|
Linear
Circular Group Item |
|
Circular Scanning
|
Least complicated - placed items in a circle and scans them electronically
|
|
Linear Scanning
|
Light moves across each row (item by item) until desired item is selected.
|
|
Group Item Scanning
|
A group of items is selected then each item in the group is eliminated until choice is made
|

|
2 important factors in vocab selection for pre literate |
1. Chosen from a functional, rather than developmental perspective 2. Age appropriate e.g. smily face symbol might mean happy for a child, but awesome for a teenager |
|
Developmental vocab |
- Words that individual doesn't know yet - Selected to encourage language growth - E.g. if a child is going to the circus for the first time clown, tiger, funny might be included - Should include words or messages that encourage use of various structures and combinations |

|
If an adult has poor speech, poor hang function, good mobility.... |
Alternative access May need some AAC options to be portable May need AAC and other AT to be integrated |
|
If an adult has poor speech, poor hand function, poor mobility.... |
Alternative access AAC options don't need to be lightweight as can be wheelchair mounted May need AAC and other AT to be integrated |
|
What are some common apps used with adults? |
Predictable Assistive chat TouchChat Proloquo2Go Clarocom |
|
Most effective measure in ALS for predicting need for AAC |
Speaking rate Intelligibility NOT sensitive enough - Too little time between loss of intelligibility and loss of speech - Recommend AAC referral when rate 100-125 wpm on the speech intelligibility test |
|

List and briefly describe the 4 phases of assessment. |
Referral- A person with a complex communication need is referred for an AAC assessmenInitial Assessment and Intervention- Assess physical access needs, sensory capabilities, cognitive skills, and focus on meeting immediate communication needs.Assessment for the future- Develope an AAC system to use in a variety of contexts, involve additional facilitators, observe the use in a variety of environments, plan and support.Follow up- Maintenance, replacement, repair, update, assess vocabulary needs, make adjustments. |
|
Describe the Opportunity and Access barriers related to communication that are assessed when using the Participation Model of Assessment |
Opportunity barriers include policy, practice, knowledge, and skill. Policy deals with legislative, funding, and instruction. Practice means “the way it’s done”, or common practices. Knowledge refers to a lack of information regarding opportunities. Skill is the actual implementation of AAC intervention.Access barriers include physical, cognitive, literacy, and visual/auditory. Physical barriers include motor abilities, can the client even operate the device. Cognitive refers to the client's abilities to understand what to do. Literacy, can the client understand written text. Visual and auditory, can the client see or hear well enough to operate the device. |
|
Define unaided and aided symbols and provide 2 examples for each. |
Unaided communication means without the use of external equipment to communicate. Some forms of this include gestures, facial expressions, vocalizations, manual sign, and eye gaze.Aided Communication refers to the use of external equipment to communicate. Examples of this would range from no-tech (Pictures, eye gaze board) to high tech (touch screens digitalized voice, Voca, iPad). |
|
Aided symbols include the following… |
real objects, text, line drawings, photographs |
