The paper presents a personal training system that allows the user to use non-verbal communication techniques that help him improve his way of speaking in public. The tool is a software solution that implements algorithms to identify elements of non-verbal communication (NVC), such as the positions of the head, hands and trunk of the users making use of cascading classifiers. It presents the developed technology and the different characteristics of the application that is an important part of the treatment in artificial vision techniques in the detection of NVC and its training.
