Recently there has been an interest in spatially aware systems for pedestrian routing and city exploration, due to the proliferation of smartphones with GPS receivers among the general public. Since GPS readings are noisy, giving good and well-timed route instructions to pedestrians is a challenging problem. This paper describes a spoken-dialogue prototype for pedestrian navigation in Stockholm...

This paper presents a framework for building user interfaces for context-aware service management. It enables us to easily deploy context-aware services at computers through user-friendly manipulations to edit documents and monitor changes and services in the real world. It is constructed as a compound document framework whose the structural composition of visual components can be adapted to ch...

We consider the problem of reconfiguring a set physical objects into desired target configuration, typical (sub)task in robotics and automation, arising product assembly, packaging, stocking store shelves, more. In this paper we address variant, which call space-aware reconfiguration, where goal is to minimize space needed for while obeying constraints on allowable collision-free motions object...

This paper describes a platform for the user-centred design and evaluation of adaptive, context-aware services in the wireless, mobile and pervasive computing markets. It focuses on evaluating the user interactions with context-aware adaptive systems while synchronising the control of the environmental context that drives adaptivity and the user’s perception of that environment. The platform us...

Information Retrieval (IR) models based on vector spaces have been investigated for a long time. Nevertheless, they have recently attracted further research interest beyond the classical statistical view of vectors and matrices. Moreover, “context” has been recognized as a crucial component of IR systems. As the way context affects IR systems is very complex, a principled approach to modeling a...
