A computer-implemented method for customizing training contents for a user, including: establishing a user profile and a personal learning corpus for the user; generating a first baseline indicating that the user is interested and a second baseline indicating that the user is not interested; monitoring the user's reactions when the user is consuming contents related to a second topic, wherein the reactions include the one or more of biometrical indicators, facial expressions, and body language; comparing the reactions with the first baseline and the second baseline to determine an interest level; and recommending additional contents related to the second topic if the interest level is higher than a predefined threshold.
