Partner-assisted scanning or listener-assisted scanning is an augmentative and alternative communication technique used to enable a person with severe speech impairments to communicate. The approach is used with individuals who, due to sickness or disability, have severe motor impairments and good memory and attention skills. [1] It is used as an alternative to direct access (e.g. pointing) to symbols, pictures, or speech generating devices when these are not used. [2]
Partner-assisted scanning is a technique used with children who have severe motor and communication impairments, and especially those with additional visual impairment, those who do not yet have an established alternative form of communication, or who are unable to use their usual method, perhaps because their electronic speech output device is being repaired. [3] Adults may also use scanning with a partner when they are not using their more high-tech alternative communication device. [2] Partner-assisted scanning can also be the main means of communication for adults in late stages of diseases such as amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS) or those in intensive care. [4] [5]
In partner-assisted scanning, the communication partner presents messages or letter choices in a sequential fashion to the individual who wishes to communicate something, and the individual then makes their selection. Scanning refers to the process of items presented one after the other, in the same patterns, until a choice is made as the desired item is reached. [6] Items can be presented either visually, by pointing, or auditorily, by speaking. [7]
Efficiency may be increased in visual partner scanning by the partner first pointing to groups of items, such as rows of letters, and once a row has been selected, proceeding to point to all letters in that row until a choice is made. [4] The communicator can spell words this way in order to express what they need to communicate. Similarly, the partner can point to groups of words. Visual scanning may also be accomplished by the partner pointing to pictures, such as those in a personal communication book, using an agreed upon pattern. [2]
The selecting system can be divided into two categories: alphanumeric and choice making. These differ, because in the alphanumeric version you scan through letters and numbers. Choice-making is where you present multiple choices. For example, when asked "Would you like a movie or book?", the communicator indicates a "yes" response. They can do this in a variety of ways, like facial expressions, vocalizations, or body gestures. To determine the best way, one's team of caretakers has to look at the individual's abilities.
Auditory scanning with a partner is often used when the communicator has very poor vision. Groups of letters can be represented by numbers, such as 1=abcdef. The partner lists off the numbers, and once a group is selected, names all letters in that group. [8] Auditory scanning can also be accomplished with lists of novel messages. The partner orally lists the options and then repeats them so the communicator can make a selection. This could be a short list of emotions to inquire as to how someone is feeling (e.g. happy, sad, frustrated). [9] The partner and communicator can memorize many lists, or "menus", with sub-lists covering different topics for communication. It is important that lists are repeated in the same order and with pauses after each item, so that there is time to respond. [10]
Jean-Dominique Bauby, who had locked-in syndrome, used partner-assisted scanning to communicate and to write his book The Diving Bell and the Butterfly . [11]
Assistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for people with disabilities and the elderly. Disabled people often have difficulty performing activities of daily living (ADLs) independently, or even with assistance. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing, grooming, and personal device care. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Assistive technology promotes greater independence by enabling people to perform tasks they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to, or changing methods of interacting with, the technology needed to accomplish such tasks. For example, wheelchairs provide independent mobility for those who cannot walk, while assistive eating devices can enable people who cannot feed themselves to do so. Due to assistive technology, disabled people have an opportunity of a more positive and easygoing lifestyle, with an increase in "social participation", "security and control", and a greater chance to "reduce institutional costs without significantly increasing household expenses." In schools, assistive technology can be critical in allowing students with disabilities to access the general education curriculum. Students who experience challenges writing or keyboarding, for example, can use voice recognition software instead. Assistive technologies assist people who are recovering from strokes and people who have sustained injuries that affect their daily tasks.
Makaton is a communication tool with speech, signs, and symbols to enable people with disabilities or learning disabilities to communicate. Makaton supports the development of essential communication skills such as attention, listening, comprehension, memory and expressive speech and language. The Makaton language programme has been used with individuals who have cognitive impairments, autism, Down syndrome, specific language impairment, multisensory impairment and acquired neurological disorders that have negatively affected the ability to communicate, including stroke and dementia patients.
Facilitated communication (FC), or supported typing, is a scientifically discredited technique, which claims to allow non-verbal people, such as those with autism, to communicate. The technique involves a facilitator guiding the disabled person's arm or hand in an attempt to help them type on a keyboard or other such device which they are unable to properly use if unfacilitated.
Computer accessibility refers to the accessibility of a computer system to all people, regardless of disability type or severity of impairment. The term accessibility is most often used in reference to specialized hardware or software, or a combination of both, designed to enable the use of a computer by a person with a disability or impairment.
Reading for special needs has become an area of interest as the understanding of reading has improved. Teaching children with special needs how to read was not historically pursued due to perspectives of a Reading Readiness model. This model assumes that a reader must learn to read in a hierarchical manner such that one skill must be mastered before learning the next skill. This approach often led to teaching sub-skills of reading in a decontextualized manner. This style of teaching made it difficult for children to master these early skills, and as a result, did not advance to more advanced literacy instruction and often continued to receive age-inappropriate instruction.
Augmentative and alternative communication (AAC) encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production or comprehension of spoken or written language. AAC is used by those with a wide range of speech and language impairments, including congenital impairments such as cerebral palsy, intellectual impairment and autism, and acquired conditions such as amyotrophic lateral sclerosis and Parkinson's disease. AAC can be a permanent addition to a person's communication or a temporary aid. Stephen Hawking, probably the best-known user of AAC, had amyotrophic lateral sclerosis, and communicated through a speech-generating device.
Speech–language pathology (also known as speech and language pathology or logopedics) is a healthcare and academic discipline concerning the evaluation, treatment, and prevention of communication disorders, including expressive and mixed receptive-expressive language disorders, voice disorders, speech sound disorders, speech disfluency, pragmatic language impairments, and social communication difficulties, as well as swallowing disorders across the lifespan. It is an allied health profession regulated by professional bodies including the American Speech-Language-Hearing Association (ASHA) and Speech Pathology Australia. The field of speech-language pathology is practiced by a clinician known as a speech-language pathologist (SLP) or a speech and language therapist (SLT). SLPs also play an important role in the screening, diagnosis, and treatment of autism spectrum disorder (ASD), often in collaboration with pediatricians and psychologists.
Speech-generating devices (SGDs), also known as voice output communication aids, are electronic augmentative and alternative communication (AAC) systems used to supplement or replace speech or writing for individuals with severe speech impairments, enabling them to verbally communicate. SGDs are important for people who have limited means of interacting verbally, as they allow individuals to become active participants in communication interactions. They are particularly helpful for patients with amyotrophic lateral sclerosis (ALS) but recently have been used for children with predicted speech deficiencies.
Aural rehabilitation is the process of identifying and diagnosing a hearing loss, providing different types of therapies to clients who are hard of hearing, and implementing different amplification devices to aid the client's hearing abilities. Aural rehab includes specific procedures in which each therapy and amplification device has as its goal the habilitation or rehabilitation of persons to overcome the handicap (disability) caused by a hearing impairment or deafness.
Tangible symbols are a type of augmentative and alternative communication (AAC) that uses objects or pictures that share a perceptual relationship with the items they represent as symbols. A tangible symbol's relation to the item it represents is perceptually obvious and concrete – the visual or tactile properties of the symbol resemble the intended item. Tangible Symbols can easily be manipulated and are most strongly associated with the sense of touch. These symbols can be used by individuals who are not able to communicate using speech or other abstract symbol systems, such as sign language. However, for those who have the ability to communicate using speech, learning to use tangible symbols does not hinder further developing acquisition of natural speech and/or language development, and may even facilitate it.
David R. Beukelman was an American speech-language pathologist who specialized in augmentative and alternative communication and communication disorders associated with neurological conditions. He was the Barkley Professor Emeritus of Communication Disorders at the University of Nebraska-Lincoln and used to be the Director of Research and Education of the Communication Disorders Division, Munroe/Meyer Institute of Genetics and Rehabilitation, University of Nebraska Medical Center, Omaha, Nebraska.
Speech and language impairment are basic categories that might be drawn in issues of communication involve hearing, speech, language, and fluency.

The International Society for Augmentative and Alternative Communication (ISAAC) was founded in May 1983 in East Lansing, Michigan, United States. Its stated purpose is to improve the communication abilities and quality of life of individuals with complex communication needs who use augmentative and alternative communication (AAC). ISAAC provides information about AAC services, policies and activities around the world thorough various publications and their website. The society publishes a journal and various other publications, organizes biennial conferences, promotes research on AAC use and AAC development as well as implements various projects.
Semantic compaction, (Minspeak), conceptually described as polysemic (multi-meaning) iconic encoding, is one of the three ways to represent language in Augmentative and alternative communication (AAC). It is a system utilized in AAC devices in which sequences of icons are combined in order to form a word or a phrase. The goal is to increase independent communication in individuals who cannot use speech. Minspeak is the only patented system for Semantic Compaction and is based on multi-meaning icons that code vocabulary in short sequences determined by rule-driven patterns. Minspeak has been used with both children and adults with various disabilities, including cerebral palsy, motor speech disorders, developmental disabilities, autism spectrum disorder, and adult onset disabilities such as Amyotrophic Lateral Sclerosis (ALS).
Switch access scanning is an indirect selection technique, used with switch access by an assistive technology user, including those who use augmentative and alternative communication (AAC), to choose items from the selection set. Unlike direct selection, a scanner can only make selections when the scanning indicator of the electronic device is on the desired choice. The scanning indicator moves through items by highlighting each item on the screen, or by announcing each item via voice output, and then the user activates a switch to select the item. The speed and pattern of scanning, as well as the way items are selected, are individualized to the physical, visual and cognitive capabilities of the user. While there may be different reasons for using scanning, the most common is a physical disability resulting in reduced motor control for direct selection. Communication during scanning is slower and less efficient than direct selection and scanning requires more cognitive skill. Scanning using technology has an advantage allows the user to be independent in controlling the assistive technology for those with only one voluntary movement.
Lightwriters are a type of speech-generating device. The person who cannot speak types a message on the keyboard, and this message is displayed on two displays, one facing the user and a second outfacing display facing the communication partner or partners. A speech synthesiser is also used to provide speech output, and some models offer the facility to connect to a printer to provide printed output.
Howard C. Shane is director of the Autism Language Program and Communication Enhancement Program at Children's Hospital in Boston, Massachusetts, former director of the Institute on Applied Technology, and associate professor at Harvard Medical School. He is internationally known for his research and development of augmented and alternative communication systems to support the communication needs of people with neuromuscular disorders, autism and other disabilities.
The rapid prompting method (RPM) is a pseudoscientific technique that attempts to aid communication by people with autism or other disabilities to communicate through pointing, typing, or writing. Also known as Spelling to Communicate, it is closely related to the scientifically discredited technique facilitated communication (FC). Practitioners of RPM have failed to assess the issue of message agency using simple and direct scientific methodologies, saying that doing so would be stigmatizing and that allowing scientific criticisms of the technique robs people with autism of their right to communicate. The American Speech-Language-Hearing Association has issued a statement opposing the practice of RPM.
The Picture Exchange Communication System (PECS) is an augmentative and alternative communication system developed and produced by Pyramid Educational Consultants, Inc. PECS was developed in 1985 at the Delaware Autism Program by Andy Bondy, PhD, and Lori Frost, MS, CCC-SLP. The developers of PECS noticed that traditional communication techniques, including speech imitation, sign language, and picture point systems, relied on the teacher to initiate social interactions and none focused on teaching students to initiate interactions. Based on these observations, Bondy and Frost created a functional means of communication for individuals with a variety of communication challenges. Although PECS was originally developed for young children with autism spectrum disorder (ASD), its use has become much more widespread. Through the years, PECS has been successfully implemented with individuals with varying diagnoses across the aged span. PECS is an evidence-based practice that has been highly successful with regard to the development of functional communication skills.
