Abstract Technology has already permeated education at all levels, ranging from pre-school to higher education. When used appropriately, Information and Communication Technologies (ICTs) can transform learning into an engaging and interactive process and enhance teaching with the use of educator-oriented tools. Nowadays, Interactive Whiteboards (IWbs) stand out as a widespread technological equipment that has already permeated classrooms, with their usage extending from pre-school to university. Many advantages exist in integrating IWBs into the classroom environment. They are considered as a great tool to improve the educational process, while their acceptance is constantly growing; that is because they enable educators to express their creativity, but equally important, because they encourage students’ active participation. 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 - which takes advantage of the facilities offered by the intelligent environment and the amenities stemming from its large dimensions (wall-size), in order to enhance educational activities and provide new educator- and student- oriented experiences. From the students’ perspective, the CognitOS Classboard, apart from offering access to useful educational applications, provides mechanisms capable of transforming the classroom into an immersive environment on demand. Such a facility can enable interaction with the real world in ways that were not possible before (e.g. immerse students into a rainforest). Additionally, taking advantage of its multi-touch functionality, the proposed system supports student collaboration in order to enhance the learning process. From the educators’ perspective, the CognitOS Classboard aims to support lecturing. In particular, the main goal is to provide a unified working environment for the large interactive board, offering a straightforward ‘natural’ interaction paradigm, which allows educators to orchestrate their teaching assets in an optimal way (e.g. use different workspaces to place different types of applications) and present information-rich material to the students. Additionally, it aims to support course preparation before class, by equipping educators with user-friendly tools that allow them to initialize the contents of the board with the appropriate material in advance. Aiming to blend seamlessly in the classroom environment and in keeping with the already existing standards and processes of teaching / lecturing, the CognitOS Classboard enhances wellestablished interaction metaphors (e.g. writing on the digital board is similar to writing on a plain whiteboard) and supports multimodal interaction through: i) touch on the wall surface with the finger or a special marker, ii) a remote presenter, iii) voice commands, iv) sophisticated techniques that take advantage of the Intelligent Classroom’s Ambient Intelligence facilities (e.g. through user position tracking, an application window can tail the educator while moving around), and v) the controller application for handheld devices (tablet). This thesis presents the CognitOS Classboard, describes the design process and its functionality, elaborates on the implementation details and discusses the results of a user-based evaluation study in the context of an Intelligent (University) Classroom.
