Embedded system as a third version of a didactic transmitter of needs that provides a way of communication to children with cerebral palsy of the spastic type

Cerebral Palsy (CP) is a disorder originated in the motor cortex of the brain. Its causes are unknown but many theories detail that it occurs during the gestation period when the fetus has not enough oxygen in the brain (hypoxia). This paper shows the last investigative stage in the development of transmitters of needs, here is detailed the third version of it, which is based on completely improving its predecessorsin order to cover a larger population of boys and girls with cerebral palsy that present clinical pictures of hemiplegia and quadriplegia. Children who suffer this disorder cannot communicate their needs, thoughts or desires even with language of gestures, because it is difficult for them to learn it and in many cases their bodies do not even allow them to move their arms. So it is necessary to find a way to provide these children with a means of communication, a non-invasive method, that is; a system that adapts its functionality to the specific needs of children. This latest version of the device brings an update of the mobile application. This is necessary for the child's interaction with their parents, teachers or therapists. The validation method of the device is the contrast of the results obtained with respect to its predecessor version. All these points including the process of development of said system, is detailed in the chapters below.
