Mobile technology is becoming ubiquitous, with usage ranging across such diverse activities as direction-finding, music storage, photography, texting, checking social-media, accessing newspapers and watching TV. This paper describes a major study examining the use of such technology by people with Learning Disabilities (LD). It concentrates on the issues related to undertaking research with this specific cohort – such as difficulties participants may have in generalising, abstract thinking, and the possible tendency to simply agree with comments or questions made by the researcher (known as acquiesce bias) - and methods being adopted to minimise or obviate these completely.
