Generic personal assistance architecture for mobile environments

The usage of mobile computers such as PDAs and mobile phones provides new services for the user. In the early days, user input or external environment information was used for defining context information for personal assistance. Some applications e.g. Location Based Services (LBS) are very handy and powerful and they enable the next generation of assistance by using user related parameters, behavior and preferences. By using new interfaces and sensors, an additional and comprehensive understanding of the user's situation can be determined. This paper shows an improving approach of the generic architecture for mobile personal situation aware assistance and gives an outlook on upcoming challenges of research in activity and assistance models
