Location-dependent and Context-Aware Computing
Stan Kurkovsky · IGI Global eBooks · 2010
Systems with context-aware features are typically able to adapt their behavior to the changes of the environment surrounding the system and/or its users without any explicit intervention of the user. Therefore, context-aware systems tend to increase the usability and effectiveness by taking into account the context of their environment. Location-based and context-aware systems are typically associated with mobile devices; they react to reflect their current physical location, time, other surrounding systems, their user(s), as well as other features of their environment, and adapt their operation to the changes of the environment. This information about the many aspects of the system‘s environment is referred to as context, which can be obtained from a variety of sources, such as RFID and other sensors, wireless network information, physical device status, maintaining information about the user(s) and many other sources.
