Preface

the AAAI-13 Activity Context-Aware System Architectures workshop builds on the groundwork laid at the first and second workshops at AAAI-11 and AAAI-12, for developing systems that capture, transfer, and recall activity context across multiple devices and platforms, used by people individually and collectively. The scope of the workshop includes finding techniques for creating context, activity-driven systems pro- viding end-user value through monitoring, exchange and support on activities which can be performed better with help of computational devices than otherwise. The consortium and workshop interest is focused on using techniques in artificial intelligence to improve the human-computer interface for better human performance of knowledge work.
