Computing device providing electronic book data with rolling images and related methods

A method for using a computing device comprising a display, a memory, and a user input pointing device, the method comprising:

• storing electronic textbook data in the memory comprising a plurality of different sets of images, each set of images being associated with at least one location within the electronic textbook data and having a common set of elements but with different arrangements of the common set of elements within the set of images based upon different respective difficulty levels;
• displaying the electronic textbook data with a primary image from among a given set of images from among the plurality of different sets of images at the at least one location on the display based upon a difficulty level selected by actuation of the user input pointing device;
• selectively hiding the primary image and displaying at least one secondary image from among the given set of images at the at least one location on the display based upon actuation of the user input pointing device so that the primary image and the at least one secondary image are alternatively viewable on said display responsive to selection by a reader during a reading session;
• and
• hiding a portion of the electronic textbook data based upon a placement of a hand icon, the placement of the hand icon being selected by actuation of the user input pointing device.

A non-transitory computer-readable medium for a computing device comprising a display, a memory, and a user input pointing device, the non-transitory computer-readable medium having computer-executable instructions for causing the computing device to perform steps comprising:

• storing electronic textbook data in the memory comprising a plurality of different sets of images, each set of images being associated with at least one location within the electronic textbook data and having a common set of elements but with different arrangements of the common set of elements within the set of images based upon different respective difficulty levels;
• displaying the electronic textbook data with a primary image from among a given set of images from among the plurality of different sets of images at the at least one location on the display based upon a difficulty level selected by actuation of the user input pointing device;
• selectively hiding the primary image and displaying at least one secondary image from among the given set of images at the at least one location on the display based upon actuation of the user input pointing device so that the primary image and the at least one secondary image are alternatively viewable on said display responsive to selection by a reader during a reading session;
• and
• hiding a portion of the electronic textbook data based upon a placement of a hand icon, the placement of the hand icon being selected by actuation of the user input pointing device.
