Interconnected collections of computational artifacts have to exhibit smart and coherent behavior in support of the users' activities and tasks across artifacts/devices, in order to be perceived as smart environments on the users' side. A promising approach to enhance the user experience in smart environments is to exploit recorded histories of the users' interactions in context (context histories for short). These histories can be used to support ubiquitous/pervasive computing applications with an enhanced understanding of the users' activities and interactions as they expand and develop over time. In addition, current contextual data is often imperfect and noisy and can be smoothed from the use of histories. Exploiting context histories may, for example, result in less distractions, more adapted and coherent behavior of multi-computer setups, and better support in information management and search. The user could end up with a more supportive and comforting environment. At the same time, however, the collection, storage, management, and exploitation of context histories is a delicate issue, as privacy, informational self-determination, and data security are touched. In smart environments, there will be multiple users interacting with multiple and heterogeneous devices, some of them with little storage and computing power. In this workshop we want to bring together researchers to discuss the trade-offs of exploiting context histories for supporting user experiences with applications in smart environments. Several systems and approaches have already been proposed. We will set out to shape a common vision for this emerging field by identifying common requirements and issues.
