Tools, Devices & Communication Systems Flashcards

What is the purpose of AAC devices?

Answer: To assist with communication

AAC (Augmentative and Alternative Communication) devices are specifically designed to help individuals with severe communication impairments express themselves. These tools provide alternative methods for communication, such as speech-generating devices, picture boards, or communication apps, thereby assisting with communication rather than replacing hearing or improving physical strength.

Which tool supports visual communication?

Answer: Picture communication board

A picture communication board is a visual tool that uses images, symbols, or photographs to represent words, phrases, or concepts. Users point to or exchange these pictures to convey messages, making it an effective method for visual communication. It is specifically designed to support individuals who communicate visually.

What feature is common in dynamic display devices?

Answer: Multiple pages

Dynamic display devices in AAC feature screens that change, allowing users to navigate through multiple pages or levels of vocabulary and functions. This capability enables access to a vast array of words and phrases, making communication more comprehensive and flexible than static display systems. The ability to switch between pages is a defining characteristic.

Why is voice output important in communication systems?

Answer: It enables speech output

Voice output is a critical feature in many AAC systems because it converts selected text or symbols into spoken words. This enables individuals who cannot speak or have limited verbal abilities to communicate audibly, participate in conversations, and be understood by others. It provides them with a 'voice' to express their thoughts and needs.

What is a key benefit of customizable AAC tools?

Answer: Individual tailoring

A key benefit of customizable AAC tools is their ability to be individually tailored to meet the unique needs, preferences, and abilities of each user. This personalization ensures that the vocabulary, symbols, access methods, and voice output are optimized for the individual, maximizing their communication effectiveness and engagement. It moves beyond a one-size-fits-all approach.

Which system uses symbol sequences for communication?

Answer: PECS

PECS (Picture Exchange Communication System) is a well-known AAC system that teaches individuals to communicate by exchanging pictures or symbols for desired items or to express thoughts. It focuses on functional communication through a structured sequence of symbol exchanges. This makes it a primary example of a system using symbol sequences.

How do eye-gaze devices support communication?

Answer: Eye tracking for selection

Eye-gaze devices utilize sophisticated technology to track a user's eye movements, allowing them to select items, type messages, or control a computer by simply looking at specific areas on a screen. This method provides a vital communication pathway for individuals with severe physical disabilities who cannot use their hands or voices effectively. It directly translates eye movements into selections.

What is the benefit of switch access in AAC?

Answer: Access for limited mobility

Switch access provides an alternative method for individuals with significant physical limitations to operate AAC devices or computers. By using a single, simple movement (e.g., pressing a button with their head, hand, or foot), users can activate a switch to select items or navigate menus. This greatly enhances accessibility for those with limited mobility.

Which factor is most important in selecting an AAC system?

Answer: Appearance

The appearance of an AAC system can significantly influence a user's acceptance and willingness to use it in various social contexts. A device that is aesthetically pleasing, discreet, or socially appropriate for the user's age and environment can reduce self-consciousness and promote consistent engagement. This factor is crucial because even the most functional system will not be effective if the user is reluctant to carry or operate it due to its look.
