Discussion on the Initial version of our User Interface Designs:
a)
The client specified that he would like the application only in the
Interactive mode rather than to have the option of both the Interactive
and the Non Interactive Mode as the main purpose of this application is
for the students to know the steps in Protein formation.
b)
He has given us snapshot of how he wants the UI of the application to look
like.
c)
The client would like to have all the functionality buttons
(Transcription, Splicing, Translation, Express Gene, Reset Gene…) at the
top of the page and based on clicking on any of the buttons only the
matter displayed on the applet screen should change instead of changing
the whole screen into a new screen.
d)
He would like to have a button on the application screen for turning the
animation ON/OFF.
e)
He looked at our UI designs and would not like the DNA strands to appear
in a helix form. He mentions that, although the helix shape for the DNA
strand would be cool to have but it would be confusing for the students
and would distract them from the actual task of the application. Hence we
would like to have the DNA strands in the application as decoupled
straight parallel complementary strands.
f)
We discussed the editing feature of the application. He liked our idea
of having a drop down list with the options of deleting, inserting… or
modifying (changing the current base to A, G, C, T) the existing
nucleotide base on which the user has double clicked.
g)
The client
specified that the student would be able to modify/edit only the DNA
sequence and edit should update every part of the gene expression. The
base edited should be highlighted thought out the entire representation of
the gene expression process. He also mentioned that the student should be
given the option to undo the last edit they made.
h)
The client
mentioned that he wanted a way to hide the promoter and the terminator
part of the DNA sequence and so in his current version of the GenExplorer
he has shown the Promoter and the Terminator with different colors. He
also mentioned that he would like to set a map for the Exon and the Intron
parts of the pre mRNA strand so that the exons labeled as exon1, exon2,
… inside black boxes above the actual exon sequences and the introns are
labeled above the intron sequences and are not labeled. This should be the
case for both while displaying the splicing part in the application as
well as in the printer friendly option of the application.
i)
Sequences should also be clearly visible when printed on a Black and White
printer for the Printer friendly version.
j)
He is comfortable with the idea of scrolling to get the picture of the
whole DNA strand for the printer friendly version rather than having them
as a line after line.
K)
He was happy
with the idea of graying out the inactive buttons, for example the
splicing button is not highlighted until the user has clicked on the
translation button and the translation process has been completed.
