1. A computer-implemented method for teaching materials using a first window of a display, with at least some of the space outside of the first window being viewable via the display, with the space outside of the first window including a second window at least partially viewable via the display, the method comprising: acquiring data, by a computing device, regarding a volitional input of a user, the data being sensed by a sensor monitoring a physical attribute associated with the user, the sensor being detached from the user; and analyzing the data by the computing device, which is coupled to the sensor and the display; and determining by the computing device from the analyzing of the data whether the volitional input is in the first window or in the second window, whereby the volitional input being in the second window indicates a learning situation different from the volitional input being in the first window.
