ABSTRACT
This introduction presents an overview of the key concepts discussed in this book. The book examines the factors that influence success and failure when people use tablets. Researchers in the field of human computer interaction (HCI) produced many early articles on the human interface guidelines to support the standardization or establishment of best practices for designers of tablets. The potential for the tablet as an education tool was apparent from the beginning. Before the iPad, Windows-based tablets and other proprietary tablets were created for, and marketed specifically to, the education sector. The nonverbal communication and augmentative communications scholars and practitioners conducted many studies comparing tablets to non-digital assistive or augmentative communication (AAC) devices. These contributions provided a basis for making changes in special education classrooms. Implementation of most educational technologies into classrooms occurs at the low to middle levels of the taxonomy and this has driven research.
