The PhonicStick®: A Novel Device for Individuals with Complex Communication Needs
Providing Children with Complex Communication Needs (CCN) with access to Phonemic Speech Output
Project funding by: Capability Scotland, The Nuffield Foundation
Introduction
Augmentative and alternative communication (AAC) is a field within assistive technology which has advanced rapidly since the early 1980’s. AAC devices usually have a voice output facility and are designed to be used by people with physical impairments, e.g., using touch screens or switch input. Since the late 1980s, there has been a research focus on using AAC technology to improve the communication and the quality of life for people with disabilities. This has resulted in the development of systems that help individuals with no functional speech to (a) communicate; (b) communicate at a faster rate; and (c) develop language.
Most speech generating devices (SGDs) provide access to pre-stored words or phrases using a code system. Several mnemonic systems are available to assist code recall, e.g. semantic compaction which uses multi-meaning icons and dynamic screens which use a hierarchical set of picture pages. The use of icons and pictures caters for non-literate users; the pool of pre-stored messages is thus not necessarily created by the user but by the supplier, therapist, carer etc.
A major problem with current SGDs is the high cognitive load imposed on users who have to master the retrieval system employed by their system. Users are seldom able to create words from scratch but need to remember what words or phrases are stored and what codes are needed to retrieve them.
User Studies
In our experience, it is often very difficult for individuals with physical disabilities to co-ordinate the operational use of conventional SGDs. However, these children often exhibit good control of powered mobility using a joystick. We wish to exploit the ability of these children to operate a joystick by developing a prototype joystick (to be known as the PhonicStick® ) which will allow children with CCN to have direct access to spoken phonemes.
A number of studies in different countries using the PhonicStick® have been conducted by now. Masters students in Speech and Language Pathology (Logopedi) at the University of Uppsala conducted studies in Scotland, Sweden and South Africa. Please look at our publications (listed below) for links to their theses and further accademic output.
