Necessity and problem of computational intelligence in welfare and rehabilitation engineering

The ultimate goal of rehabilitation for the elderly and people with disabilities is not to recover their lost functions, but to make them happy. Self-determination is most important for this purpose. For example, most tetraplegics want to be able to feed by themselves, because a satisfactory meal improves the quality of their lives. If computational intelligence could perform the task perfectly as they pleased, it could make them happy. However, a simple tool without intelligence, operated by them, can realize a better quality of life than state-of-the-art imperfect computational intelligence. Contrary to this, such individuals do not want to wash dishes by themselves. An automatic system with computational intelligence would be useful in this case. It could affect people with mental problems positively or negatively according to the circumstances. Computational intelligence should only be used when it can improve the quality of their lives overall.
