Introducing TU100 ‘My Digital Life’: Ubiquitous computing in a distance learning environment
In this paper we describe the Open University’s progress towards delivering an introduction to ubiquitous computing within a distance-learning environment. Our work is strongly influenced by the philosophy of learning-through-play and we have taken technologies originally designed for children’s education and adapted them for adult learners, many of whom will have no formal experience of computer science or information technology.
We will introduce two novel technologies; Sense, a drag-and-drop programming language based on Scratch; and the SenseBoard, an inexpensive hardware device that can be connected to the student’s computer, through which they can sense their environment and display outputs.
This paper is not intended as a detailed discussion of individual technologies (they will follow in time), rather it should serve as an introduction to the Open University’s method of teaching and how we hope to continue to recruit new computer scientists and engineers using novel technologies
A UBIQUITOUS TECHNOLOGY FRAMEWORK FOR CURBING THE BOKO HARAM MENACE IN NIGERIA
The security threat posed by the Boko Haram sect in Nigeria has remained unabated with no hope in sight. Weexamined the concept and applications of ubiquitous technology and taking advantage of its potentials, proposed anarchitectural framework – N-tier Ubiquitous Architectural Framework (NUAF) – for curbing the Boko Harammenace in Nigeria. NUAF is a hierarchical and segregational distributed architectural framework which in itssimplest form consists of the base-tier, inner-tier and top-tier. The real life implementation of NUAF is howeverdependent on some anticipated research sucesses in nanotechnology and wireless network security.Keywords: Internal security, Terrorism, Boko Haram, Ubiquitous technology and Distributed architectur
Futures in the making: Practices to anticipate 'ubiquitous computing'

The imagination, proposal, or playing out of ubiquitous computing environments are bound up with particular ways of constructing futurity. This paper charts the techniques used in ubiquitous computing development to negotiate that futurity. In so doing, it engages with recent geographical debates around anticipation and futurity. The discussion accordingly proceeds in four parts. First, the spatial imagination engendered by the development of ubiquitous computing is explored. Second, particular techniques in ubiquitous computing research and development for anticipating future technology use, and their limits, are discussed through empirical findings. Third, anticipatory knowledge is explored as the basis for stable means of future orientation, which both generates and derives from the techniques for anticipating futures. Fourth, the importance of studying future orientation is situated in relation to the somewhat contradictory nature of anticipatory knowledges of ubicomp and related forms of spatial imagination

Performance and Interoperability In Solar
Ubiquitous computing promises to integrate computers into our physical environment, surrounding us with applications that are able to adapt to our dynamics. Solar is a software infrastructure designed to deliver contextual information to these applications. To serve the large number and wide variety of context-aware devices envisioned by ubiquitous computing, Solar must exhibit both high performance and the ability to interoperate with many computing platforms. We created a testing framework to measure the performance of distributed systems such as Solar, as well as a pluggable data-transfer mechanism to support the dissemination of information to heterogeneous applications. This paper explores the testing framework developed, analyzes its findings concerning the performance of the current Solar prototype, presents several optimizations to Solar and their effects, and finally discusses the design of the pluggable data-transfer mechanism
Quality of Context in Context-Aware Systems
Context-aware Systems (CASs) are becoming increasingly popular and can be found in the areas of wearable computing, mobile computing, robotics, adaptive and intelligent user interfaces. Sensors are the corner stone of context capturing however, sensed context data are commonly prone to imperfection due to the technical limitations of sensors, their availability, dysfunction, and highly dynamic nature of environment. Consequently, sensed context data might be imprecise, erroneous, conflicting, or simply missing. To limit the impact of context imperfection on the behavior of a context-aware system, a notion of Quality of Context (QoC) is used to measure quality of any information that is used as context information. Adaptation is performed only if the context data used in the decision-making has an appropriate quality level. This paper reports an analytical review for state of the art quality of context in context-aware systems and points to future research directions
Ubiquitous Computing and Cellular Handsets—are menus the best way forward?
Embedded interactive computer systems, such as those found in cellular handsets, can be hard to use. The
combination of small form factor – limited input and output potential – and an increasing feature set, result in devices which confuse novice users. Although most of these devices utilise hierarchical menu structures to mediate the interaction between user and device, we believe that these menus are poorly designed and that other interaction styles may be more appropriate. In this paper we will investigate how well menu design research has been used by current handset manufacturers. We will also propose and report on the success of some new interface designs and finally examine how new Internet technologies, like WML, might be
used to further improve the handset’s interface
