In more ways than one, assistive technologies can have a profound impact on humans and their operations within society. Understanding these emerging technologies is crucial to their effective use in improving human lives. Human-Computer Interfaces and Interactivity: Emergent Research and Applications aims to address the main issues of interest within the culture and design of interactive systems for individuals living with disabilities. This premier reference work addresses a range of approaches including, but not limited to, the conceptual, technological, and design issues related to human-computer interaction, issues of interest to a range of individuals including academics, university teachers, researchers, post-graduate students, public and private institutions, and HCI developers and researchers.
