Prinianakis, A., Stefanidi, H., Leonidis, A., Korozi, M., Katzourakis, A., Stamatakis, E. and Antona, M. (2021) An Intelligent Modular Student Desk 15th International Technology, Education and Development Conference


With the emergence of the Ambient Intelligence (AmI) paradigm, Intelligent Environments became a reality and have already permeated various domains of everyday life such as work, health, entertainment and education. The Intelligent Classroom of ICS-FORTH, adheres to the human-oriented nature of AmI environments -whose primary goal is to satisfy the needs of the people living in them- and features a collection of interdependent technologically-enhanced artefacts (i.e., desk, teacher’s workstation, whiteboard) that are capable of exchanging information and communicating with each other, offering a unified interaction experience. The student’s desk is a key classroom artefact, where students spend most of their class time, so this work aspiring to enhance their daily educational activities introduces an Intelligent Desk, namely modDesk, featuring a modular design. Its construction allows customizable surfaces to be added or removed on demand, so as to support the specific and different needs of each course. Considering that related studies recommend to equip students with a display along with an appropriate input method as it would be beneficial for the educational process, the surfaces of modDesk feature built-in monitors and input devices, but also enable students to connect their handheld devices (e.g., Smartphones, Tablets). Via sophisticated mechanisms the desk identifies any external devices that are docked to its surface or that are in close proximity, and determines the capabilities they offer. Based on the identified capabilities, modDesk adapts to offer better support to the student. This new generation desk aims to further increase students’ engagement and motivation, providing hands-on experience and offering personal study spaces featuring specialized equipment.

Leonidis, A., Korozi, M., Sykianaki, E., Tsolakou, E., Kouroumalis, V., Ioannidi, D., Stavridakis, A., Antona, M. and Stephanidis, C. (2021) Improving Stress Management and Sleep Hygiene in Intelligent Homes Journal Article, Sensors 2021, 21, 2398.


High stress levels and sleep deprivation may cause several mental or physical health issues, such as depression, impaired memory, decreased motivation, obesity, etc. The COVID-19 pandemic has produced unprecedented changes in our lives, generating significant stress, and worries about health, social isolation, employment, and finances. To this end, nowadays more than ever, it is crucial to deliver solutions that can help people to manage and control their stress, as well as to reduce sleep disturbances, so as to improve their health and overall quality of life. Technology, and in particular Ambient Intelligence Environments, can help towards that direction, when considering that they are able to understand the needs of their users, identify their behavior, learn their preferences, and act and react in their interest. This work presents two systems that have been designed and developed in the context of an Intelligent Home, namely CaLmi and HypnOS, which aim to assist users that struggle with stress and poor sleep quality, respectively. Both of the systems rely on real-time data collected by wearable devices, as well as contextual information retrieved from the ambient facilities of the Intelligent Home, so as to offer appropriate pervasive relaxation programs (CaLmi) or provide personalized insights regarding sleep hygiene (HypnOS) to the residents. This article will describe the design process that was followed, the functionality of both systems, the results of the user studies that were conducted for the evaluation of their end-user applications, and a discussion about future plans.

The proliferation of Internet of Things devices and services and their integration in everyday environments led to the emergence of intelligent offices, classrooms, conference, and meeting rooms that adhere to the paradigm of Ambient Intelligence. Usually, the type of activities performed in such environments (i.e., presentations and lectures) can be enhanced by the use of large Interactive Boards that—among others—allow access to digital content, promote collaboration, enhance the process of exchanging ideas, and increase the engagement of the audience. Additionally, the board contents are expected to be plenty, in terms of quantity, and diverse, in terms of type (e.g., textual data, pictorial data, multimedia, figures, and charts), which unavoidably makes their manipulation over a large display tiring and cumbersome, especially when the interaction lasts for a considerable amount of time (e.g., during a class hour). Acknowledging both the shortcomings and potentials of Interactive Boards in intelligent conference rooms, meeting rooms, and classrooms, this work introduces a sophisticated framework named CognitOS Board, which takes advantage of (i) the intelligent facilities offered by the environment and (ii) the amenities offered by wall-to-wall displays, in order to enhance presentation-related activities. In this article, we describe the design process of CognitOS Board, elaborate on the available functionality, and discuss the results of a user-based evaluation study.

In the domain of education, an Intelligent Classroom that employs Ambient Intelligence technologies can not only improve learning and student performance, but also support educators with the various educational tasks, such as lecturing, course preparation and classroom management. Given that the board is one of the key artifacts of any classroom, using technology to enhance it offers students and educators rich opportunities by providing access to a wide range of applications, capturing and maintaining a simultaneous focus of attention for large learner groups, supporting collaboration and encouraging discussion. To this end, this work presents the CognitOS Classboard, an educator- and student- oriented framework, employed on the “Intelligent Classroom Board” - a wall-to-wall projected interactive board- offering a variety of tools and applications aiming to support lecturing and enhance the learning process. Aiming to create highly engaging and fascinating learning experiences for the students, the CognitOS Classboard apart from offering access to useful educational applications, features sophisticated mechanisms that can transform the classroom into an immersive environment on demand. It supports multimodal interaction through touch, mid-air gestures, voice commands, and user position tracking, while a tablet and a desktop application were developed for permitting the management and overview of the board. This paper reports the functionality of the “CognitOS Classboard” and the findings of an evaluation experiment conducted with User Experience experts.

The LECTOR Podium – An innovative Teacher Workstation for the intelligent Classroom of the Future

Stefanidi, E., Korozi, M., Leonidis, A., Antona, M., & Papagiannakis, G. (2020) The LECTOR Podium – An innovative Teacher Workstation for the intelligent Classroom of the Future In the Proceedings of the 12th International Conference on Education Technology and Computers (ICETC 2020), London, UK, 23-26 October 2020.


This paper explores a new approach to a teacher’s workstation in the context of the intelligent classroom of the 21st century. Nowadays, the term “intelligent” is not only associated with efforts to incorporate smart/mobile devices into the learning experience (distance learning, educational games/apps, etc.), but also to equip the physical environment of the classroom with technologically enhanced objects. These technologically augmented artefacts (Student Desk, Interactive Classroom Board and Educator’s Workstation) are embedded discreetly in the classroom’s environment. One of the main concerns in designing and developing such artefacts is to facilitate seamless interaction between educators and students, as well as to enable unobtrusive monitoring and supervision of the students by the educators. This paper presents LECTOR Podium, a system that liberates teachers from the confinement of a desk and introduces a flexible and empowering workstation in the form of a smart arm-chair. This arm-chair assumes the role of a control center, enabling the educator to monitor and operate every feature and artefact of the intelligent classroom.

In today's fast-paced and demanding society, more and more people are suffering from stress-related problems; however, intelligent environments can be equipped with facilities that assist in keeping it under control. This paper presents CaLmi, a system for Intelligent Homes that aims to reduce the stress of its residents by: (a) monitoring its level through a combination of biometric measurements from a wearable device along with information about user's everyday life and (b) enabling the ubiquitous presentation of relaxation programs, which deliver multi-sensory, context-aware, personalized interventions.

Shaping the Intelligent Classroom of the Future

Korozi, M., Stefanidi, E., Samaritaki, G., Prinianakis, A., Katzourakis, A., Leonidis, A., & Antona, M. (2019) Shaping the Intelligent Classroom of the Future In International Conference on Human-Computer Interaction (pp. 200-212). Springer, Cham. Vancouver


This paper explores the general concept of the classroom of the future from a technological perspective, and proposes a set of indicative key facilities that such an environment should incorporate. Over the years, there has been an abundance of related research work aiming to build a “smarter” classroom, initially incorporating distance learning, educational games, and intelligent tutoring systems. More recently, many approaches have revolved around the advancements in the domains of Ambient Intelligence and Internet of Things, resulting in the enhancement of the traditional classroom equipment and furniture with processing power and interaction capabilities (e.g. intelligent desk, smart whiteboard) and the integration of emerging solutions in teaching and learning methods (e.g. AR, VR). The proposed intelligent classroom though is a holistic approach towards a student-centric educational ecosystem, which will incorporate state-of-the-art technologies to support (among others) alternative pedagogies, learning through immersive hands-on experiences and collaboration via flexible class layouts. To that end, this paper reports the various ambient facilities of the classroom and the accompanying software, while a prototype of this environment is currently under development in the AmI Facility of FORTH-ICS.
