A Systematic Literature Review into the Effectiveness of Visual Scene Displays to Support Communication.
Bell, J. (2014) A Systematic Literature Review into the Effectiveness of Visual Scene Displays to Support Communication., no. 90.
Recent developments in technology and research into the field of augmentative and alternative communication (AAC) have enabled the development of a wider range of AAC. This gives people with a variety of communication impairments the opportunity to be better supported. This study aimed to carry out a systematic literature review to examine the literature currently available on visual scene displays and provide a summary of this. It also aimed to investigate the advantages and disadvantages visual scene displays hold for people with different communication impairments and any areas of future research. Five databases were searched with inclusion criteria kept to a minimum to obtain as many articles as possible, with the initial search producing 62 articles. After duplicate removal and two screening processes, 22 articles completed the final list of articles. The communication impairments described within the articles fell into three different categories; typically developing, aphasia and autism spectrum disorder, with the "other" category including articles that did not clearly fit into the other three categories. Within each category advantages were found. Visual scene displays have the potential to support communication for people with different communication impairments. This can range from supporting the learning of new vocabulary to enabling a person to share stories and personal experiences. However, the literature within the area of visual scene displays is not vast and further research is required to ensure individuals with communication impairments are receiving the most appropriate augmentative and alternative communication to meet their needs.
