Abstract
A new dynamic software architecture for wearable computers is proposed. Key properties of this MEX architecture are examined and compared to some other existing software architecture. One application utilizing MEX, called WalkMap, is presented. The aim of the applications currently under development is to enhance the communication and cooperation of the users utilizing wearable computers in their daily lives. Based on that the software components needed to access context information anywhere and the hardware requirements arising from constant usage are considered. The hardware platform for the software architecture developed is briefly described.
