Abstract: An automated adaptive engine alters content in real-time based on feedback received. With this engine human adjustment is no longer necessary or is kept to minimum by choice. The engine may build an Emotional Profile (EP) from scratch, may modulate an existing EP based on detected real-time responses, or also may randomly try different things to detect new response from the user. The engine may be applied with an interactive media application, preferably embodied as an interactive book, that adjusts content automatically in real-time, based on a reader's quality of emotional response (or mental response) against expectation, without requiring any human intervention. The response feedback is detected as expressed through voice, facial expressions, vitals such as pulse or blood pressure, and/or activities in different parts of the brain, or other means of such expression.
