6.3 Simulator Screenshots of the E-Reader

The basic version of the software for the E-Reader has been implemented using the Nano-x

framework. To utilize the memory more efficiently all windows are not loaded when the

program is initialized. Windows are created and mapped as the user navigates from one

window to another. All previous windows are destroyed when the user leaves that specific

window hence saving memory space. The following are some screenshots of menus and

popup windows. The idea is to clarify the implementation’s ambiguity as much as possible for

the reader of this report. In this chapter, to present the data in a structured form, the

screenshots illustrates one branch of the menu tree i.e. after navigating the main menu when

the user selects “Read Books” option then sub menu of “Read Books” will be shown. Inside

the sub menu the user has the option to select any book from the list of available books. When

the book is open different options, like turning pages, search a word inside the book and jump

to any desired page, is given to the user.

The first screenshot in figure 6.3 is the main menu, which will be shown to the E-Reader’s

user after boot-up process. The user shall, after navigating with the arrow-keys, select any

option from the main menu by pressing “Enter” button or “F4” button to exit (i.e. Turnoff

device) from the program.
