Mobile, Ubiquitous and the Sense of Space,, mobile devices we know and use today risk to generate a kind of . of the sense of space. Mobile means, when we deal with portable devices, that we can access information no matter where we are; our territory of life becomes indistinct.

Informed by the types of projects that children have done with this material in the context of educational research in science and engineering, we present a few scenarios for why children would bui

Scalable and Flexible Location-Based Services for Ubiquitous Information Access,esign of the Internet does not provide any conceptual models for addressing this issue. As a result, developing a system that requires this functionality becomes a challenging and costly task, leading to individual solutions that only address the requirements of specific application scenarios. In th

Enabling Context-Awareness from Network-Level Location Tracking,erywhere. However, user’s mobility also means that the context in which the information system is used change dramatically. To be useful in these new environments, applications will have to be adaptive, which requires context-awareness. We propose in this paper an efficient way to export context-dep

Advanced Interaction in Context,ods.When the user‘s situation, place or activity changes, the functionality of the device should adapt to these changes. In this work we propose a layered real-time architecture for this kind of context-aware adaptation based on redundant collections of low-level sensors. Two kinds of sensors are di

Handheld Computing Predictions: What Went Wrong?,ctions made over a 10 year period, investigating what went wrong, and what went right, with handheld computing predictions. Handheld computing predictions can be divided into three phases, depending on the product concept definition widely held at the time: handheld computers as penbased computers,
