Systemic approach to an analysis of the design of printed, digital, and hyper-digital books

For a long time, printed books were the only tools to support teaching-learning, but as technology advanced digital books emerged. In addition to being content-specific repositories, they also enabled the development of new formats and the connection with other bases. This work begins with the selection of three books of different formats: printed, digital and hyper-digital. Then, the differences in relation to the design were analyzed from a systemic approach. The aim was to verify if there is a need for adaptation and improvement to fit the various existing devices and if the existing supports are complementary or substitutive between them.
