The Human - Computer Interaction (HCI) Laboratory of ICS-FORTH is an internationally recognised research centre of excellence with accumulated experience in user interface software technologies (novel interaction techniques/devices, toolkits and 4th Generation Languages for user interface development, wearable computing, virtual environments), and design methodologies and tools (user and context modelling, design techniques and processes, usability engineering). The Laboratory carries out leading research activities focused on developing user interfaces for interactive applications and telematic services that are accessible, usable, and ultimately acceptable for diverse users in the emerging Information Society. The main thrust of this line of work focuses on promoting the concept of User Interfaces for All, and fosters an evolutionary path towards more systematic and proactive approaches to the development of accessible and usable user interfaces. It involves ensuring accessibility at design time, and developing user interfaces to interactive applications and telematic services, which provide universal access and usability to all potential users. The Laboratory hosts and operates the Centre for Universal Access and Assistive Technologies. The main objective of the Centre is to support the equal participation and socio-economic integration of people with disabilities in the Information Society, by designing products and services accessible and usable by the widest possible end-user population.
