ComunicArte is a VR tool for training the ability of public speaking. It shows an environment where the speaker confronts a virtual audience that reacts in real time to the speaker's features, such as voice or gestures, and to his or her biometrics (heart rate or skin conductivity among others). In this talk, we present the first unit of experience of this tool, in which we measure the feelings projected by the speaker’s voice tone and his or her gaze direction.
