The CongitOS Classboard: Supporting the teacher in the Intelligent Classroom

Nikitakis, G., Ntagianta, A., Korozi, M., Leonidis, A., Antona, M., Stephanidis, C. (2020) The CongitOS Classboard: Supporting the teacher in the Intelligent Classroom 14th annual International Technology, Education and Development Conference, At Valencia


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.

Grammenos, D., Georgalis, Y., Partarakis, N., Zabulis, X., Sarmis, T., Kartakis, S., et al. (2009) Rapid prototyping of an ami-augmented office environment demonstrator 13th International Conference on Human-Computer Interaction, HCI International 2009, San Diego, CA., 5612 LNCS(PART 3) 397-406.


This paper presents the process and tangible outcomes of a rapid prototyping activity towards the creation of a demonstrator, showcasing the potential use and effect of Ambient Intelligence technologies in a typical office environment. In this context, the hardware and software components used are described, as well as the interactive behavior of the demonstrator. Additionally, some conclusions stemming from the experience gained are presented, along with pointers for future research and development work.
