The proposed system is the result of a research project focused on pupils with sensorial, neuropsychological, and relational impairments. The project involves innovative technological systems that the users (speech terabits psychologists and preprimary and primary schools teachers) could adopt for training and assessment of language and speech. Because the system is used in a real scenario (the Italian schools are often affected by poor funding for education and teachers without informatics skills), the guidelines adopted are low-cost technology; usability; customizable system; robustness. 1. Introduction Learning systems providing user interaction within physical spaces have been carried out over the years. However the high cost and the high complexity of the technologies used have always implied that their use by pupils in real context was limited to occasional visits or short periods of experimentation. Our aim is to provide an interactive multimodal environment (developed in C++) that can be integrated with the ordinary educational activities within the school. For this purpose, we use common technologies¡ªsuch as webcams, microphones, and Microsoft Kinect sensors¡ªin order (i) to provide tools that allow teachers to adapt or create autonomously the educational activities content to be carried out with the system and (ii) to implement a user interface for the management software that does not require specific computer skills. Our system implements the five different types of interaction stated by Moreno and Mayer [1]: (1) dialogue, (2) control, (3) manipulation, (4) search, and (5) navigation. Indeed, these five levels are very familiar during the everyday learning activity. Here are some examples: (1) a comparison/oral discussion in which the exchange of information is not unilateral, but the opportunities to the students to ask questions and express their opinions are given influencing the content of the lesson; (2) oral exposure in which the student has the ability to control the speed and to stop the explanation in order to benefit from the educational content at their own pace; (3) a scientific experiment that leaves the possibility for the student to test different parameters and see what happens; (4) the ability to independently seek information on a certain subject within a %U http://www.hindawi.com/journals/js/2013/564864/
