**4. Conclusions**

In line with this introductory chapter, the remaining of the book confirms that several scientific areas are involved in the development of assistive and rehabilitation systems. First of all, in terms of computer sciences, at least five specialties are represented: (i) software engineering, for the proper development of the applications; (ii) artificial intelligence, for the implementation and assessment of smart behaviours; (iii) health computing, to adapt the platform to the medical requirements; (iv) serious games, to increase the motivation of the patients; and (v) affective computing, to interpret the emotional state of the user. The second important area is human factors and ergonomics, which focus on (i) human-centred design, to make sure that the system is user-friendly, and (ii) user experience, to perform usability and accessibility studies. Finally, human sciences (psychology and neurosciences) and health sciences (paramedical fields) have a key role in (i) the design of experimental protocols, (ii) data analyses and (iii) adaptation of the traditional therapy to the new technologies. The next chapters address the interconnection between these complementary areas through the development of solutions for both assistive and rehabilitation purposes.
