Research Groups

Data Management in Mobile Computing and Sensor Networks

The main research interests of the group include Data Management for Systems and Networks, Information Systems, Energy-efficient Distributed Processing, ICT services for eHealth and Ambient Assisted Living. The group has a long term participation in research projects funded from national and international organizations, including the European Union and the Cyprus Research Foundation (RPF). More specifically, the group has participated in a number of IST projects related to mobile, wireless, sensor networks and distributed computing, such as SocialRobot, CoLiving, IPAC, CONET, mPower, LinkCare, HealthService24, and also RPF-funded projects like: PersonaWeb, FireWatch, MELCO, EKPAIDEION, DITIS.

SCRAT Group - Semantic and Cognitive Research Adaptivity Technologies

SCRAT Group's reasearch focus is on Web Personalization and Adaptation, eLearning, Semantics, Meta Information, Intelligent Systems. SCRAT Group's vision is to develop a dynamic comprehensive personalization filter that will be based on the automatic extraction of humans' most intrinsic values, namely, User Perceptual Preference Characteristics, and serve as the prime element of any entity (Web-based system, advanced training system, mobile system, virtual environment, spacecraft, aircraft, robot, etc.), liable to accept any type of semantic content, alter and return it, adjusted to the unique characteristics and preferences of the user. User Perceptual Preference Characteristics (UPPC) are all "the critical factors that influence the visual, mental and emotional processes liable of manipulating the newly information received and building upon prior knowledge, that is different for each user or user group. These characteristics determine the visual attention, cognitive and emotional processing taking place throughout the whole process of accepting an object of perception (stimulus) until the comprehensive response to it".

AAL Group - Ambient Assisted Living

The AAL JP group’s activities aim to create better condition of life for the older adults and to strengthen the industrial opportunities in Europe through the use of information and communication technology (ICT). The group is focusing on integrating the latest research in fall prevention, geriatric exercise physiology, imagery for healing, and brain fitness in our holistic, mind-body approach to healthy living for all stages of aging and supports the elderly’s activities of daily life. It carries out its mandate through the funding of national and international projects that involves small and medium enterprises (SME), research bodies and user’s organizations (representing the older adults).

Distributed Mobile Systems Group

Our team has been working towards realizing innovative mobile solutions that leverage the knowledge inferred from sensors embedded in smart wearable and mobile devices (e.g., user emotions, physical activity, mobile device resource utilization, etc.) for improving user experiences and performance in various mobile application domains. Representative research projects in this line of work include: an adaptive mobile advertising framework based on user characteristics and mobile resource utilization; a middleware for combining heterogeneous wearable technologies in mobile apps with minimal developer effort; and mobile/wearable frameworks for assisting people with disabilities (e.g., people with hearing and vision impairments) in engaging seamlessly with their surrounding environment using the advanced capabilities offered by today's smart wearable devices.
