We describe initial efforts at implementing a flexible, modular face identification framework in the context of a pervasive computing environment including handheld computers. Currently, the handheld is used for image capture, while all computation is performed on a back-end server, though other possibilities are discussed. Handheld face identification is difficult due to limitations in process...

In 2011, now 20 years after M. Weiser’s “The Computer for the 21st Century” (1991), the vision impacting the evolution of Pervasive Computing is still the claim for an intuitive, unobtrusive and distraction free interaction with omnipresent, technology-rich environments. In an attempt of bringing interaction “back to the real world” after an era of keyboard and screen interaction (Personal comp...

Pervasive computing is promising emerging endeavor which focuses on the capability for users to perform daily computer activities unobtrusively. Pervasive computing solutions are broad to encompass variety of technologies and real life applications. It provides an environment for people to interact with embedded computers. Networked devices are aware of their surrounding objects, peers and are ...

The mass deployment of sensors and pervasive computing systems expected in the next few years, will require novel approaches to program and gather information from such systems. Suitable approaches will be general purpose, independent of a specific scenario and sensor deployment, and able to adapt autonomically to different scales and to a number of unforeseen circumstances. This chapter focuse...

The explosive evolution of pervasive computing environments presents several new challenges such as smart spaces, invisibility, localized scalability, and masking uneven conditioning. One of the key challenges in such environments is how to manage security and access control. A suitable approach for managing access control in pervasive computing environments should consider different features o...

One of the main features of pervasive computing systems is their need to be dynamically reconfigured in order to properly adapt to the continuous changes in their environment conditions (context). An appropriate solution to provide reconfigurability is Aspect-Oriented Software Development, which allows that optional functionalities can be enabled/disabled and services can be replaced with light...

Pervasive computing environment and users’ demand for multimedia personalization precipitate a need for personalization tools to help people access desired multimedia content at anytime, anywhere, through any devices. User preference learning plays an important role in multimedia personalization. In this paper, we propose a learning approach to acquire and update user preference for multimedia ...

Pervasive computing environments aim to integrate components which are highly heterogeneous, not only in terms of software technologies, but also in terms of hardware resources. Unfortunately, classic middleware platforms do not appear able to cope with such a level of heterogeneity and new communication mechanisms are thus required. This paper presents Plugin-Orb, an adaptive middleware for mo...

This paper presents two novel handheld projector systems for indoor pervasive computing spaces. These projection-based devices are “aware” of their environment in ways not demonstrated previously. They offer both spatial awareness, where the system infers location and orientation of the device in 3D space, and geometry awareness, where the system constructs the 3D structure of the world around ...
