Nowadays, ubiquitous computing - devices all around us - create a new reality to cope with. This artificial environment is subtle added to the real world and feed us with huge quantities of information pushing to the limits our adapting capacity. We need a high speed information processing. For the human brain the fastest solution is offered by affective neural system. Emotions have an unconscious evaluative role, but the offered solutions are not always functional. It is the moment when personal emotional state could unconsciously migrate to a dysfunctional zone. Thus, the following question arise: "How can we handle an emotional state we are not conscious of?" In this article we propose E-PET -Emotion PErsonal Trainer, a ubiquitous system for the detection and interpretation of emotions. It is a hardware free concept since it is projected to be incorporated in different types of already existing devices such as: smart phones, intelligent goggle and / or smart watches. Information about emotional state is taken from audio channel (words and paralanguage parameters) because this approach requires no additional equipment. The system provides warnings and recommendations in order to help the person to handle its emotional reactions. Moreover, we analyze the opportunity of the above mentioned system, from the potential users' point of view. An investigative research is conducted to find out the key factors for a successful implementation of E-PET. The results encourage us to continue our research in this field and to promote a new technological view on handling [self-] emotions.
