paperback book and an ebook
What are the main concepts
and metaphors that have been used? How do they differ? What aspects of the
paper-based artifact have informed the digital app? What is the new
functionality? Are any aspects of the conceptual model confusing? What are the
pros and cons?
Comparing the above objects, an ebook is
designed as a copy of the paperback book to provide ease of carrying to other
locations without any extra luggage. It is a redundant form of paperback book.
The ebooks are designed in a manner to correlate with the paperbacks, giving
reader the same feel while swiping the pages of the ebook as turning the pages
of the paperback book. It
can have numbered pages, table of contents, pictures and graphics, exactly like
a printed book to imitate the paperback. One can mark pages and highlight text
on it. It is a conceptual model of a paperback book with same look and feel to
give a more realistic experience.
The only difference between the two is
that one is hard copy and the other is soft copy.
The new functionality of an ebook which a
paperback book lacks is the zoom in and out capability. The user can easily
zoom in or out adjusting the size of the characters to ease his visibility.
The ebook becomes confusing when it comes
to resizing the text, because
of the fact that text will flow differently from page to page if we resize. If,
for example, you increase the text size, fewer words will now fit on the
“page”, so the text that was once on page 8 might end up on page 9.

maps are based on a conceptual model of the paper-based map, using similar
concepts to show a geographical area. The digital maps are based on the
metaphor of paper-based map in terms of looks but are provided with the much
One of the several new functionalities
added to the digital maps so far, includes navigation. This feature helps user
to compute distance from one place to another and estimates the time of arrival
at the destination. Other
functions include the use of gestural signs in the form of arrows to show which
direction to move.
The conceptual model gets confusing when
it comes to network. The digital maps are restricted to network. Facing a
network issue directly affects the smartphone map locations.
1. User can locate himself.
2. Navigation facility
3. Estimation of time of arrival at the destination
1. Digital apps are restricted by the size of the
device while a paper-map can be spread-out to see a whole area.
2. Network constraint
3. Battery constraint; paper maps can be viewed
multiple times while digital maps are confined to the battery of the device.
