Operational Demands of AAC Mobile Technology Applications on Programming Vocabulary and Engagement During Professional and Child Interactions

ABSTRACT Typically, the vocabulary in augmentative and alternative communication (AAC) technologies is pre-programmed by manufacturers or by parents and professionals outside of daily interactions. Because vocabulary needs are difficult to predict, young children who use aided AAC often do not have access to vocabulary concepts as the need and interest arises in their daily interactions, limiting their vocabulary acquisition and use. Ideally, parents and professionals would be able to add vocabulary to AAC technologies “just-in-time” as required during daily interactions. This study compared the effects of two AAC applications for mobile technologies: GoTalk Now (which required more programming steps) and EasyVSD (which required fewer programming steps) on the number of visual scene displays (VSDs) and hotspots created in 10-min interactions between eight professionals and preschool-aged children with typical development. The results indicated that, although all of the professionals were able to create VSDs and add vocabulary during interactions with the children, they created more VSDs and hotspots with the app with fewer programming steps than with the one with more steps, and child engagement and programming participation levels were high with both apps, but higher levels for both variables were observed with the app with fewer programming steps than with the one with more steps. These results suggest that apps with fewer programming steps may reduce operational demands and better support professionals to (a) respond to the child’s input, (b) use just-in-time programming during interactions, (c) provide access to more vocabulary, and (d) increase participation.

“Social Media has Opened a World of ‘Open communication:’” experiences of Adults with Cerebral Palsy who use Augmentative and Alternative Communication and Social Media

An online focus group was used to investigate the experiences of nine individuals with cerebral palsy who use augmentative and alternative communication (AAC) and social media. Information was gathered related to (a) advantages of social media, (b) disadvantages of social media, (c) barriers to successful use, (d) supports to successful use, and (e) recommendations for other individuals using AAC, support personnel, policy makers, and technology developers. Participants primarily chose to focus on social media as a beneficial tool and viewed it as an important form of communication. The participants did describe barriers to social media use (e.g., technology). Despite barriers, all the participants in this study took an active role in learning to use social media. The results are discussed as they relate to themes and with reference to published literature.

My World Has Expanded Even Though I'm Stuck at Home: Experiences of Individuals With Amyotrophic Lateral Sclerosis Who Use Augmentative and Alternative Communication and Social Media.

PURPOSE This study aimed to expand the current understanding of how persons with amyotrophic lateral sclerosis (pALS) use augmentative and alternative communication and social media to address their communication needs. METHOD An online focus group was used to investigate the experiences of 9 pALS who use augmentative and alternative communication and social media. Questions posed to the group related to (a) current use of social media, (b) advantages of social media, (c) barriers to independent use, (d) supports to independent use, and (e) recommendations for developers, policy makers, and other pALS. RESULTS Participants primarily reported that use of social media was a beneficial tool that provided increased communication opportunities, connections to communication partners, and networks of support. Specific results are discussed with reference to the research as well as implications for practice and recommendations for future research. CONCLUSIONS As individuals with ALS experience loss of function, some communication modes may no longer be viable. Providing access to different modes of communication, including social media, can allow independence, participation and better quality of life.

Social media experiences of adolescents and young adults with cerebral palsy who use augmentative and alternative communication

Abstract Purpose: This pilot study aimed to expand the current understanding of how adolescents and young adults with cerebral palsy (CP) and complex communication needs use social media. Method: An online focus group was used to investigate the social media experiences of seven individuals with CP who used Augmentative and Alternative Communication (AAC). Questions posed to the group related to social media: (a) advantages; (b) disadvantages; (c) barriers; (d) supports; and (e) recommendations. Result: Adolescents with CP who use AAC used a range of communication media to participate in daily interactions, including social media. An analysis of the focus group interaction revealed that the participants used social media to: bypass the constraints of face-to-face interactions; communicate for a number of reasons (e.g. maintain relationships, share experiences); and support independent leisure (e.g. playing games, looking at pictures/videos). Despite the advantages, the participants discussed barriers including limitations related to AAC technologies, social media sites and literacy skills. Conclusion: The results suggest that service providers should implement interventions to support social media use, including enhancement of linguistic, operational and strategic competence. Technology manufacturers should focus on improving the designs of AAC apps and social media sites to facilitate access by individuals who require AAC.

Effect of mobile technology featuring visual scene displays and just-in-time programming on communication turns by preadolescent and adolescent beginning communicators

Abstract Purpose: Visual scene displays (VSDs) and just-in-time programming supports are augmentative and alternative communication (AAC) technology features with theoretical benefits for beginning communicators of all ages. The goal of the current study was to evaluate the effects of a communication application (app) on mobile technology that supported the just-in-time programming of VSDs on the communication of preadolescents and adolescents who were beginning communicators. Method: A single-subject multiple-baseline across participant design was employed to evaluate the effect of the AAC app with VSDs programmed just-in-time by the researcher on the communication turns expressed by five preadolescents and adolescents (9–18 years old) who were beginning communicators. Result: All five participants demonstrated marked increases in the frequency of their communication turns after the onset intervention. Conclusion: Just-in-time programming support and VSDs are two features that may positively impact communication for beginning communicators in preadolescence and adolescence. Apps with these features allow partners to quickly and easily capture photos of meaningful and motivating events and provide them immediately as VSDs with relevant vocabulary to support communication in response to beginning communicators’ interests.

“Augmentative and Alternative Communication (AAC) Will Give You a Voice”: Key Practices in AAC Assessment and Intervention as Described by Persons with Amyotrophic Lateral Sclerosis

&NA; The purpose of this study was to describe the perceptions of persons with amyotrophic lateral sclerosis (pALS) who use augmentative and alternative communication (AAC) with the AAC assessment and intervention process. Twenty‐one pALS with complex communication needs participated in a multipart survey (and follow‐up e‐mails) to provide information on their experiences with AAC assessment and intervention. A majority of the participants agreed with the importance of three key AAC intervention principles: appropriate staging of the timing of assessment and intervention activities, inclusion of communication partners, and the use of multiple modalities and strategies as communication supports. Most participants reported that their assessment and intervention experiences included at least some aspect of these three key practices. The results of this study suggest that the identified best practices in AAC should be reviewed and implemented on an individualized basis for pALS with complex communication needs.

Effects of dynamic text in an AAC app on sight word reading for individuals with autism spectrum disorder

Abstract The purpose of this study was to investigate the effects of Transition to Literacy (T2L) software features (i.e., dynamic text and speech output upon selection of a graphic symbol) within a grid display in an augmentative and alternative communication (AAC) app, on the sight word reading skills of individuals with autism spectrum disorders (ASD) and complex communication needs. The study implemented a single-subject multiple probe research design across one set of three participants. The same design was utilized with an additional set of two participants. As part of the intervention, the participants were exposed to an AAC app with the T2L features during a highly structured matching task. With only limited exposure to the features, the five participants all demonstrated increased accuracy of identification of 12 targeted sight words. This study provides preliminary evidence that redesigning AAC apps to include the provision of dynamic text combined with speech output, can positively impact the sight-word reading of participants during a structured task. This adaptation in AAC system design could be used to complement literacy instruction and to potentially infuse components of literacy learning into daily communication.

The effects of explicit instruction in academic vocabulary during shared book reading on the receptive vocabulary of children with complex communication needs

Abstract The purpose of this study was to evaluate the effect of explicit vocabulary instruction during shared reading experiences on the acquisition of receptive academic vocabulary for children with complex communication needs. A single-subject, multiple-probe design was used. Three preschool-aged children (i.e., one with autism spectrum disorder, one with developmental delay, and one with a rare genetic disorder) were each taught two sets of vocabulary words. Intervention consisted of explicit vocabulary instruction associated with shared reading of academic texts. All three children acquired 10 targeted academic vocabulary items receptively and maintained vocabulary knowledge for at least 4 weeks. Data also suggest probable generalization to new representations. Additionally, participants became more adept at learning via this method, acquiring the second vocabulary set in significantly less time. Results indicate that explicit vocabulary instruction during shared reading experiences can be effective for teaching receptive vocabulary to children with complex communication needs.

Comparison of the effects of mobile technology AAC apps on programming visual scene displays

Abstract Parents and professionals who work with individuals who use augmentative and alternative communication (AAC) face tremendous time pressures, especially when programming vocabulary in AAC technologies. System design (from programming functions to layout options) necessitates a range of skills related to operational competence and can impose intensive training demands for communication partners. In fact, some AAC applications impose considerable learning demands, which can lead to increased time to complete the same programming tasks. A within-subject design was used to investigate the comparative effects of three visual scene display AAC apps (GoTalk Now, AutisMate, EasyVSD) on the programming times for three off-line programming activities, by adults who were novices to programming AAC apps. The results indicated all participants were able to create scenes and add hotspots during off-line programming tasks with minimal self-guided training. The AAC app that had the least number of programming steps, EasyVSD, resulted in the fastest completion times across the three programming tasks. These results suggest that by simplifying the operational requirements of AAC apps the programming time is reduced, which may allow partners to better support individuals who use AAC.
