One embodiment includes a computer-implemented method using a window environment of a display, with a detached sensor, to teach a user. Another embodiment includes a computer system helping teach a user using a detached imaging sensor. In yet another embodiment, a computer-aided-educational system considers a user's concentration level when teaching the user. The system monitors automatically more than once a user's concentration-sensitive behavior while the user is working on study materials. Through monitoring the user's volitional or involuntary behavior, the system provides an indication on the user's concentration level. Based on the indication, the system could react such as by providing rewards, punishments, and stimulation; or changing the study materials. The system can also react by asking the user a question to stimulate the user or to assess the user's understanding. Based on the user's response, the system may change to more appropriate study materials, or different presentation styles.
