AAC Midtwerm Flashcards
Fixed Displays
Not changing, EG a sheet of paper with pictures on it
Dyminc Displays
The screen changes EG food icon takes you to a screen of food choices
Hybrid Displays
a combo – eg: a step sequencer. The message can change, but it’s a set message and you can’t pick what’s beyond what is sequenced into the device.
Visual scene display
This is a picture with hot spots. You touch the hot spots for words that are represented by the picture. Picture of events work well.
Display orientation is in relation to the ________.
Floor
What are standard icon sizes?
½ in, 1 in, 3 in. Really, it just needs to be large enough for the client to see.
Physical contact
touch. Does not mean putting pressure on it. It simply means to touch something.
Physical pressure or depression
must exert pressure on a selected key, think keyboard
pointing
there is no contact. client selects by pointing at target.
timed activation
must apply pressure for x amount of time. This is good for individuals who do not have quick reflexes, or the ability to press/release (eg: someone who drags his or her hand).
release activation
only activated upon release
What is filtered activation, and for whom does it work best?
When an individual is accessing the set, filtered activation will select the item that the individual has contacted most. This is best for someone with a tremor and their hand touches something repeatedly.
What is scanning?
A system that is set up with many options. It is best for individuals that cannot select directly.
Circular scanning
scans in a circular pattern
linear scanning
scans lines
group-item scanning. useful for?
aka categories. This is especially useful for alphabet boards.
Scanning timing and speed
Some individuals may require more time because of motor or cognitive limitations.
Directed (inverse) scanning
Hold button down first, and when you get to the one you want, you let it go. Selection is on the release of the button, not the depression of the button.
Automatic (regular or interrupted) scanning
Scanning starts, when you see the one that you want, you press and release. Selection is done on the depression of the switch.
Step scanning
Press until you get to the one that you want. If you want the 3rd one, you press the button three times to get to it.
Activation Feedback
Sensory feedback that lets you know you’ve made a selection. EG: When you shut your phone off and you hear a click/swoosh that indicates you’ve shut down your device. It may also be a vibration, or another tactile feeling.
Message feedback
This is more of an auditory or visual feedback. The message itself is not important here – it’s just to say that they’ve successfully selected the communication set. Communication partners should be aware of message feedback.
What is message output and input?
This is the actual message
text-to-speech
Type message, and a voice speaks what is written
Digitized speech
Natural speech that has been put into a recorder to make it as natural as possible (proloquo, and dynavox).
advantages to synthesized speech
provides a mode of communication that it relatively easy to understand. It is non-threatening to listeners and allows communication with nonliterate partners. Allows communication without having to first gain attention. Comm can be done from a distance.
cons to synthesized speech
choosing a voice is a very personal, difficult decision to make.
VIsual output
A supportive output method for AAC. It serves to clarify messages when the listener does not understand synthetic or natural speech. Basically, a written message.
Hard Copy
A printer may be a part of a communication device, or an adjunct to it. It produces a permanent, “hard copy” output on paper.
Computer screen messages
These are widely used in AAC technology as feedback and output. May utilize orthographic and/or specialized symbols.
Unaided symbols
Non-electronic forms of output such as gestures or manual signs that impose memory requirements on both of the participants in the communicative exchange. No permanent display is available, and all of the gestures or manual signs must be produced from memory by the sender and processed in memory by the receiver.
What are non-electronic symbol displays?
Communication partners interact directly with the symbol set itself. As the person who uses AAC identifies the symbols of choice, the partner formulates the message, often speaking it aloud as feedback
