A task-based approach to data and context management in a virtual personal server space

In English This paper presents our vision for an activity based pervasive com- puting system based on a virtual personal server space. Our target demographic is a group of elder computer users. Using collaborative inter1faces technologies; we focus on reminiscence activities for their use in promoting social and intel- lectual fitness. Current computer applications while designed for single use are not suitable for multi-user, multi-device and multi-modal interaction. Our pro- posed architecture (middleware) consists of three planes of service (data, con- text and activity). The context plane mediates access to various services (de- pending on the current user activity) while optimizing data access around sim- ple activity models.
