Matching person to technology model Flashcards
Matching Persons and AAC Technology model - areas
Primary components
- language representation methods, vocabulary, methods of utterance generation
Secondary components
- user interface, control interface/selection methods, output
Tertiary components
- peripheral features, training and support, tele-rehabilitation
MPAT- Primary components
Language representation methods - single meaning pictures - alphabet based methods - semantic compaction Vocabulary - core vs fringe Method of utterance generation - SNUG (spontaneous novel utterance generation) - Pre- stored utterances
MPAT - Secondary components
User interface - symbols, navigation, automaticity, human factors Selection methods/ control interface - direct selection (eye gaze, keyboard) - Scanning (switches) - Morse code Output: - speech, display, data logging
MPAT - Tertiary components
Peripheral and integrated features
Training and support
Tele-rehabilitation
Single meaning pictures
Primary component
- one picture for one word/phrase
- does not need literacy
- explicit teaching
- large number of pictures
- organisation really important
- smooth transition from low tech
- excessive programming may be needed
Semantic compaction
Primary component
- one picture for multiple meanings, used in conjunction to make sentences
- does not need literacy
- lots of training and practice
- small amount of pictures represents large vocabulary
- potentially develops motor programs, promotes learning
Alphabet based
Primary component
- words spelt using keyboard
- needs literacy
- unlimited vocabulary
- small symbol set (26 letters)
- rate enhancement features available
- can be slow and physically demanding
- easy concept if they can spell and read
- easy to understand for communication partner
Spontaneous Novel Utterance Generation
Primary component
- combines words and phases
Pre-stored messages
Primary component
- quick access to pre-stored utterances
Symbols - secondary
Symbols (boardmaker, pixons, softpics, symbolstix, COMPIC)
Navigation - secondary
Page navigation - main page leads to other pages - the larger the vocab, the more the pages - single meaning pictures - Types: Activity display Semantic/grammatical display Pragmatic organisation Visual scene display (picture of scene) Icon sequencing (semantic compaction)
Selection method
Direct (hand, foot, keyboard, head pointer, mouse)
Scanning via switches
Eye gaze
Morse code
Speech output
Recorded speech - natural, recorded by someone - needs lots of memory to store. - can't access words that haven't been recorded Synthesized speech - computer generates, robotic voice - can generate an unlimited number of words - less memory needed - range of accent, pitch, rate
Peripheral features
- durability, portability
- display
- email, social network
- camera
- photo album
- carrying options,
- data logging
Training and support
- set up
- internet access
- upgrades
- technical skills needed by support team
- environment- sunshine, rain
