Perspectives, SIG 12, Vol. 3, Part 1, 2018
In these articles, authors explored various alternative access methods for augmentative and alternative communication with a variety of populations. One author introduces brain-computer interfaces (BCIs, reviews both the misconceptions about them and the important factors to consider when evaluating a BCI for use by someone with CCN. In another article, the author describes advances in access technology already being employed as access solutions to SGD’s and highlights areas for advancement and refinements of access technologies. Another author reviews research evidence related to eye tracking and gaze technologies with various populations. The final article focuses on teaching switch access for individuals who have significant communication, physical and sensory disabilities and who are unable to use direct selection. In this article, the use of switch access with scanning is explored in terms of how to teach motor/cognitive aspects with aided language receptive input and expressive use.
You will be able to:
- evaluate the appropriateness of a brain-computer interface as part of the communication plan for a client
- describe the current state of alternative access for individuals with complex communication needs and severe physical impairments
- identify at least three factors that can affect using eye gaze as an access method
- describe the rationale and need for teaching motor cognitive skills for using switches as an access method for AAC and educational technology
- identify the benefits of two switch step scanning in comparison to timed scanning access methods
- explain the Stepping Stones to Switch Access process for moving from cause effect learning to motor automaticity for switch access
