The project is born of the will to want to know in an objective way the mental state of people who can not express it by themselves or who are not even aware of it because it is valuable information to improve their well-being and quality of life, To improve their therapies and customize them to make them like them and more effective, “explains IRD research director Joan Oliver.


The problem is that these people not only can not express their emotions but they do not use the help tools that are used with others, such as face recognition software, so we thought the solution was to look in your mind and in your Body physiological signals emitted by its state of mind, because we know from the literature that each emotion is associated with physiological patterns, “said Jainendra Shukla, a robotic researcher involved in the project.


The handicap was that these patterns did not exist in people with intellectual disabilities, so the first task of IRD researchers was to develop them by combining external information-facial expression, eye tracking, subjective information from therapists who know the person- With internal information – heart rate, electrodermal and cerebral activity – of some of the residents of the Ave Maria Foundation while provoking different intense, positive and negative emotions.


With all that information, and obtained in other experiments mediated by therapists who interpreted their mood, researchers have developed MuDERI, a multimodal database for the recognition of emotions among people with intellectual disabilities, in which it has been systematized and Labeling each mood state from the physiological signal patterns found in the experiments.
