In an ambient intelligence world, devices work in concert to support people in carrying out everyday life activities and tasks in a natural way using information and intelligence that is hidden in the network connecting these devices. Ambient intelligence emphasizes people and user experience and ensuring ultimately that the technology disappears into our surroundings until only the user interface remains visible to users. The International Journal of Ambient Computing and Intelligence (IJACI) will specifically focus on the convergence of ubiquitous computing, context, intelligent systems, networking and security. Ubiquitous computing will focus on mobility, location and the development of various ad hoc networking capabilities that exploit numerous low-cost computing devices. Intelligent systems research will focus on learning algorithms and pattern matchers, speech recognition, gesture classification and situation assessment. Context awareness will concentrate on the tracking and positioning of objects' and people's interactions with their environments. Finally, an appreciation of human-centric computer interfaces, intelligent agents, network security, indoor positioning and the social interactions of objects in environments is essential.
