An AAC (Augmentative and Alternative Communication) device user can navigate the world using various strategies and tools. Here are some key approaches:
- Direct Selection: Users can directly select symbols or words on their AAC device by using touch screens, mouse pointers, or eye-gaze technology. This enables them to communicate their needs and preferences.
- Scanning: Scanning is another method where the AAC device highlights various options or categories one at a time. The user can select their desired option by pressing a switch, blinking, or making a specific movement. Different scanning techniques include linear scanning, row-column scanning, or automatic scanning.
- Partner-Assisted Scanning: In this approach, a communication partner presents options to the AAC user who then indicates their choice through movements, eye-gaze, or gestures. The partner assists in facilitating communication by narrowing down options and asking questions.
- Vocabulary Organization: AAC devices often offer various vocabulary organization systems such as categorization, word prediction, and quick access to frequently used phrases. These features help users navigate and find the words or symbols they need more efficiently.
- Environmental Control: AAC devices can also be programmed to control environmental devices such as lights, television, or home automation systems. This enables the AAC user to independently navigate their physical environment and perform daily tasks.
It’s important to note that the specific navigation methods vary depending on the type of AAC device, individual user preferences, and motor abilities. Regular practice, training, and customization of the device according to the user’s needs can greatly enhance their ability to navigate and interact with the world effectively.
