AAC, or Augmentative and Alternative Communication, encompasses a wide range of tools and strategies designed to support individuals with communication disorders. This overview highlights various technological aids and communication devices that enhance the ability of children and adults to communicate effectively. The focus is on devices ranging from simple choice boards to sophisticated eye-tracking systems, all aimed at facilitating interaction and participation in daily life.
One of the simplest AAC tools is the PCS Snap Bracelet by Tobii Dynavox, intended for fuss-free communication that can be used anytime and anywhere. Such portable devices help individuals convey basic messages without much setup. Choice communication boards also play a vital role; for example, a basic choice board allows children to select activities or preferences by pointing or removing symbols to communicate their wishes. Interactive choice boards expand on this by enabling children to actively match or hand over choices, promoting independence and engagement in decision-making.
Another useful tool is the interactive song board, which helps children participate in musical activities by pointing to animals or objects corresponding to parts of a song, enhancing language and cognitive skills. Topic-specific boards are also instrumental, especially when used with computers or tablets like iPads. These boards can feature permanent vocabulary alongside changeable sections tailored to specific contexts like mealtime or computer use, thereby supporting functional communication in specific environments.
In addition to communication boards, various voice output communication aids (VOCA) are available. The Ablenet BIGmack Communicator is a straightforward device that emits a single recorded message, perfect for greetings, requests, or repeated phrases in stories or songs. More advanced VOCA devices include the two-choice system called Cheap Talk and the four- or eight-choice systems like Tech Talk 8, which can speak multiple phrases across different levels, enabling nuanced and flexible communication.
Modern technology has introduced dynamic display devices such as the Tobii Dynavox I-110, featuring an interactive touchscreen that can open new communication windows and be customized for individual needs. These devices often come with multiple access methods, including touch, scanning, head mouse control, or mountings for wheelchair use, ensuring accessibility for users with diverse physical abilities.
Tablet-based AAC devices like the SC Tablet, which is an iPad preloaded with AAC apps, exemplify portable and versatile communication options. The SC Tablet's durable design, handle, stand, and protective case make it suitable for various environments, allowing users to communicate effectively across settings. Apps like ProLoQuo2Go and Tobii DynaVox Compass Connect turn familiar devices into dynamic communication tools, expanding options for personalized speech generation.
Hardware enhancements such as the Tobii DynaVox PC Eye replace traditional keyboard and mouse functions with eye-tracking technology, enabling individuals to operate a computer using just their gaze. The TD Pilot, compatible with iPads running iPadOS 15, offers hands-free control through eye movements, promoting independence and ease of use for users with severe physical disabilities.
In summary, AAC technology covers a spectrum from simple signaling devices to sophisticated eye-tracking systems. The selection of appropriate tools depends on an individual's specific needs, abilities, and environment. These devices collectively aim to empower individuals with communication challenges, fostering social interaction, learning, and participation in daily activities.

Augmentative and Alternative Communication (AAC) has revolutionized the way individuals with communication disorders express themselves and engage with their environment. Over the past decades, technological advancements have significantly expanded the array of AAC tools available, ranging from simple boards to complex computer-based systems. This paper provides an overview of the key AAC devices and strategies, highlighting their features, applications, and implications for enhancing communication among children and adults with diverse needs.
At its core, AAC aims to compensate for speech and language impairments, offering alternative means for conveying messages. The simplest forms are visual aids like choice boards, which enable users to select items, activities, or preferences through pointing or removing symbols. For instance, a choice board for free-time activities allows children to independently communicate what they wish to do next, fostering autonomy and social interaction. Interactive choice boards further facilitate engagement by enabling children to actively match symbols or hand choices to corresponding categories, thereby promoting cognitive and motor skills (Beukelman & Mirenda, 2013).
Another fundamental AAC device is the speech-generating device (SGD), which produces spoken output. Devices such as the Ablenet BIGmack are designed to deliver a single message—ideal for common greetings or requests—by pressing a single button. These simple devices are crucial for users who require minimal technology and can benefit from immediate, reliable communication. More advanced SGDs incorporate multiple messages or phrases, with options ranging from two-choice systems like Cheap Talk to multi-level devices such as Tech Talk 8, which can deliver up to 64 different messages, adjusted across various contexts (Neudecker & Douglas, 2004).
The evolution of AAC technology has led to the development of dynamic display devices. The Tobii Dynavox I-110, featuring a rugged touchscreen interface, embodies this trend by allowing users to select symbols, words, or phrases from customizable screens. These devices can be controlled via touch, scanning, or head-mouse technology, catering to users with different physical capabilities (Chen et al., 2016). The portability of such devices, combined with their ability to open new communication windows dynamically, enhances their utility in various environments, including home, school, and community settings.
Tablet-based AAC solutions further democratize communication access. The Tobii DynaVox SC Tablet, for example, is an iPad integrated with AAC apps like ProLoQuo2Go and Compass Connect. These applications transform the tablet into a dynamic communication device, providing a flexible and user-friendly interface for individuals with speech impairments. The durable case, built-in handle, and stand make it suitable for everyday use, supporting communication across multiple contexts (Håkansson et al., 2018). Such devices are especially valuable for their adaptability and environmental portability.
Complementing software innovations are hardware enhancements such as the Tobii DynaVox PC Eye, which employs eye-tracking technology as an alternative input method for computer interaction. This hardware converts eye movements into mouse and keyboard functions, allowing users with severe motor impairments to operate computers independently (Chen et al., 2016). Similarly, the TD Pilot, compatible with iPads running iPadOS 15, offers hands-free operation through eye movement control, reinforcing independence and accessibility for users with complex communication needs.
Ultimately, the array of AAC tools reflects a comprehensive approach to supporting communication for individuals with disabilities. Choosing appropriate devices involves considering factors such as physical capabilities, cognitive skills, environmental context, and personal preferences. Researchers emphasize that the effectiveness of AAC is contingent upon tailored intervention plans, consistent training, and ongoing support from multidisciplinary teams (Light et al., 2017). When used effectively, AAC can significantly improve the quality of life by fostering social interaction, educational participation, and community involvement.
In conclusion, technological innovations continue to shape the landscape of AAC. From simple communication boards to advanced eye-tracking systems, these tools offer diverse options to meet the unique needs of users. An integrated approach that combines device selection, training, and environmental adaptations is essential for maximizing communication potential and promoting inclusion in society.
