Introduction
The Capstone project consists of designing a template for the Accessible Books for Shore
Educational Collaborative. Accessible Books are popular children’s books that have been recreated through
the use of scanning and recording to enable the non-reader to access them via technology. These books are
mainly intended for high interest/low reading level students with disabilities. The graphics and the text of a
selected book are displayed on the computer screen with narration added through either digitized (human
reader) or synthesized (computer speech) speech. These books with their rich graphic content and human
voice narration provide access to reading materials so children can read and re-read their favorite books
independently. These books are created with speech capabilities that enable switch and adapted access
methods.
There are numerous ways in creating the “Accessible Books Template”, using programs such as
Microsoft Powerpoint, Clicker 5, and Intellipex Studio. However we have came up with the most efficient
way in creating the Accessible Books Template, by using an complete programming language such as
Visual Basic. The template consists of three forms included as part of a core software prototype, which
includes the Welcome Screen, Create Book screen as well as the Library; the Welcome Screen allows the
user to easily navigate around the program from book creating to accessing the database library for the
Accessible Books.
Looking in depth at creating the Accessible Book within the “Create Book” form, the user gets to
select the template by preference, initiate the title and the author of the book and gets to select the subjects
as well as the grade level components. Once the components have been selected the user gets to edit the
book in Powerpoint and make further modifications, such as add text and pictures to slides. Once the book
has been created it will be manually saved in Powerpoint presentation, Powerpoint Show and an HTML
format. From here onwards the book is viewed within the Library interface where the user has the option to
search through titles by inputting the relevant text in the search bar or has the option to select the grade
level and the subject level criteria to narrow down the results. Once the list is populated the user gets to edit
the book to make further modifications or gets to play the book in Powerpoint show format. The user has
also connecting buttons located within the forms to switch between the different forms for convenience and
finally the preview window located in “Create Book” and “Library” forms is used to illustrate a quick
3
snippet of the book that’s been selected or a template that’s been created as part of the program. Thus,
making this software an easy to use, compatible and assistive to folks with reading disabilities.
Important information conveyed while creating the Accessible Books are the Copyrights
violations and the inclusion of photos. Copyright prevents us from altering the texts, but the texts can be
presented a different size or can be broken into couple of pages. The Accessible Books need to consist of
numerous stock photos pertaining to the novel and that reflects the child’s interests.

Design Details
Project Goal
The goal of this project was to build a complete software tool to assist any classroom
environment or learning centers, addressing reading proficiency needs.
Project Outline
Our project involved creating a software prototype template for Accessible Books. We
begin with the initial installer file that would install the software’s GUI and the Text-ToSpeech program that’s embedded in the prototype and the Accessible Books are then
created through the GUI by assigning the different fields then are directed into MS
Powerpoint. Once the book has been created it is stored in the server and is distributed
amoung the client PCs (See Figure 1).
Figure 1 – Accessible Books Block Diagram

Design Parameters
Welcome Screen
The accessible book initial GUI appears after the installer file has been installed.
This form includes the “Create Book”, “Edit Book” and “Read Book” functions. The user
gets to select between the three functionalities based on their choice to either create an
accessible book, edit a previously created accessible book, or to read a accessible book
that’s stored in the database. The exit button quit the program.
Figure 2 – Accessible Books Welcome Screen
Create Book
In the Create Book form the user gets to select a default template from the list of
default templates that’s pre-created and included in the software. The selected template
could be viewed in the template preview window. The user then inputs the book title
followed by the author’s name and selects a single grade level or multiple grade levels
6
followed by choosing a single subject or multiple subjects and hit the Go button. This
creates the accessible book in the database and opens the book in PowerPoint for further
modifications. Once the accessible book is modified using the standard PowerPoint
features the book is saved in PowerPoint presentation format, PowerPoint Show format
and PowerPoint HTML format. Saving the accessible book in three formats populates the
book in edit book and read book forms. The buttons that’s included to the bottom of the
page are the navigational buttons where the user can switch between the forms or return
to the main screen.
Figure 3 – Accessible Books Create Book
Edit Book
In the Accessible Books Edit book form. The user gets to select a book from the
database and makes modifications through PowerPoint. The user can narrow the search
results of the book by choosing a single or multiple grade levels, as well as selecting a
single or multiple subjects. The user could also search for a specific accessible book by
entering keywords such as the book’s title or the Author’s name. The user could use the
7
book preview window as a snippet to view the entire book before selecting the book.
After modifying the changes in PowerPoint, the user saves the book as PowerPoint
presentation, PowerPoint HTML and PowerPoint show. Saving it in these forms
populates the book into the Edit Book and Create Book forms.
Figure 4 – Accessible Books Edit Book
Read Book
In the Read Book form the user select a book from the database and play the book
directly in PowerPoint show format. The user can use the book preview window to see
the content of the book before initiating play. The books can also be sorted by grade
levels and subject area. To further narrowing down the search results key words such as
Author or the Book Title can be entered to display the search results. The navigation
buttons at the bottom of the program help switch between forms as well as return to the
main menu.

Conclusion
The final result of my project has fulfilled the original purpose. Though some
modifications were made in the interest of time and application such as creating the
database library and using it as an entirety for the prototype, the essence of the project
was maintained and was highly valuable. In the coming days the project will be
delivered to Shore Educational Collaborative to supplement their mission of educating
their students possessed with reading proficiency with this utility.
