Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) had drawn a lot of attention as methods for realizing a ubiquitous society. RFID and WSN are two important wireless technologies that have a wide variety of applications and provide limitless future potentials. RFID facilitates detection and identification of objects that are not easily detectable or distinguishable by usin...

s computing technology increasingly becomes part of our daily activities, we are required to consider what is the future of computing and how will it change our lives? To address this question, we are interested in developing technologies that would allow for ubiquitous sensing and recognition of daily activities in an environment. Such environments will be aware of the activities performed wit...

Activity-oriented computing (AOC) is a paradigm promoting the run-time realization of applications by composing ubiquitous services in the user's surroundings according to abstract specifications of user activities. The paradigm is particularly well-suited for enacting ubiquitous applications. However, there is still a need for end-users to create and control the ubiquitous applications because...

Persistent poor acoustic conditions can imbalance humans’ psychophysical capabilities. A good project starts with either correct measurements of the existing parameters or hypothesis new sound conditions. International standards define invasive measurement and procedures that disturb user activities. For this reason, alternative methodologies have been developed by mounting real-time sound-moni...

Exposure to electromagnetic fields (EMF) is a cause of concern for many people. The topic will likely remain for the foreseeable future on the scientific and political agenda, since emissions continue to change in characteristics and levels due to new infrastructure deployments, smart environments and novel wireless devices. Until now, systematic and coordinated efforts to monitor EMF exposure ...

Space borne radar data facilitates continuous monitoring of almost any location on the earth (limitations in polar zones) with quite low costs. Almost weather-independent operation of radar systems enables a reliable and continuous record of data from earth’s surface. In the framework of an ESA pilot project (AO335), ENVISAT polarimetric SAR data of years 2004 and 2005 are examined for their us...

Current progress in wearable and implanted health monitoring technologies has strong potential to alter the future of healthcare services by enabling ubiquitous monitoring of patients. A typical health monitoring system consists of a network of wearable or implanted sensors that constantly monitor physiological parameters. Collected data are relayed using existing wireless communication protoco...

A ubiquitous computing environment will become a solid social infrastructure for recording human experiences in the real world and facilitating human activities. The captured activity can be used as a good source of novel communication in the infrastructure. This paper focuses on the non-cumbersome recording, abstracting, and summarizing of experiences as well as sharing these experiences among...

The growth of ubiquitous computing has given rise to a range of possibilities for context-based application development. Technologies for mobile computing and context-awareness can be combined to create innovative ubiquitous computing applications. However, the ubiquitous computing paradigm poses a number of difficult challenges that must be repeatedly faced by developers. For each ubiquitous c...
