Bandpass shielding enclosure design for modern handheld communication devices with internal electric-dipole and magnetic-loop antennas

Abstract Speech-language pathologists, working in a multicultural, community-based environment for young children with special needs in Vancouver, Canada, collected information on 84 clients using AAC from a chart review. The speech-language pathologists collected additional usage information and attended a group interview to discuss barriers and facilitators of AAC. Thirty-one percent of the children were using AAC. Children aged between 16 and 72 months typically relied on multiple modes of communication, including sign, communication boards and binders, and low- and high-tech communication devices. All of the children used at least one type of unaided mode. Fifty-five percent used pictures or communication boards/displays, and 29% used technology with speech output. Similarities in usage of AAC were noted in home and child-care settings with increased use of unaided in homes and a slightly increased use of aided communication in child care settings. Speech-language pathologists reported that the time needed for AAC intervention as well as limited funding for high-tech devices continue to be major barriers. Additional research is needed to describe current AAC practices with young children particularly from minority linguistic and cultural backgrounds. Stakeholder input is needed to explore perceptions of children's usage of AAC in daily life with familiar and unfamiliar communication partners.

Innovations in technology have resulted in increased use of tablets, mobile devices, and applications as augmentative and alternative communication (AAC) systems for children with complex communication needs (CCN). Although research has been conducted on the specific characteristics of AAC technologies, many interfaces remain replications of prior communication devices with little consideration of the features of newer platforms. A greater concern is that these interfaces may not be based on empirical evidence or derived from key developmental language theories. As such, these interfaces may place additional demands on children with CCN instead of supporting their development of language content, form, and use. The purpose of this paper is to discuss potential interface supports for AAC systems that capitalize on current technologies and draw upon key tenets of developmental theory.
