Systems and Technologies

Ambient Intelligent systems are explicitly spatial, they arise out of concerns for the movements and actions of people in space and they suggest a model of spatial design and architecture that employs interaction systems to create different modes of communication in an environment.
A variety of technologies can be used to enable ambient intelligent environments. The technologies used are directly dependant on the type of activity to be undertaken and therefore equipment required and intelligence needed. Technological capabilities are progressing at rapid speed. In accordance with Moores Law, data density on integrated circuits is continuing to double every eighteen months. Storage, capacity, CPU, speed, memory, wireless transfer speed and battery energy are all showing similar rates of change. More functionality is becoming possible at lower cost, with easier configuration and more wide spread possibilities. The environments that are created today have an essential requirement to provide a platform for possible change; otherwise what is created today will not be appropriate for use in five year’s time.
A typical example of this interaction could be a bio sensor network monitoring physiological parameters – heart rate blood pressure or sugar levels. Some of the sensors may be body worn others may be integrated into the surroundings connected through a network. An example of this is in health monitoring applications in which alarms or drug doses may be adapted using information from the ambient sensors, both at network level and on a one to one basis.
The benefits of ambient intelligence are in their ability to adapt an environment to counteract uncomfortable architectural parameters or to a personalised preference of comfort in order to create a space of cognitive balance. Lighting can adjusts its intensity level and colour profile to your level of stress or your activity needs, kitchens are able to adapt its configurations to cognitive needs during cooking, offering recipe guidance and real-time monitoring. Desks in offices are smart in predicating needs for computing and building systems adapt air quality for comfort and lighting levels for productivity.
