Abstract

See full text

A method for controllable toggling viewing of written materials with adjuvant or explanatory notation material as a teaching or memorization tool. The method comprises the steps of imprinting adjuvant or explanatory notation materials adjacent to or in close conjunction with a visible text or notation, as a non visible or an invisible imprint. The non visible invisible adjuvant or explanatory notation material is made to become temporarily visible or viewable with a heat source or a viewing device for a controlled desired period of time by using the visible adjuvant or explanatory notation to perform a reading or writing function. Removing the viewing device or reducing heat renders the adjuvant or explanatory notation non visible or invisible.
