A. Analysis of the Website Canal Kids for Children
Looking at the children´s website “Kids Channel” 1 , we
can saw it has several children learning and fun items, as
shown in Figure 5.
Figure 5 – Site Kids Channel / Home
The initial homepage “Home” use many pictures and
colors to draw the attention of the child user. The website
makes use of colors, sounds and color changing on the top
banner and it draws the attention of children with ADD, as
recommended below:
• Children approve the use of animations and sound [13];
• Use different types of sounds and visual effects [14].
After examination of the website home page, we found it is
not developed appropriately for the target audience. Thus, if
the user is a child and has the attention deficit disorder (ADD)
the selection rule R1 will be started by the GuideExpert
system resulting sets of guidelines for the appropriate user –
child-user, ADD-user.
In the games item, as shown in the Figure 6, the content is
very extensive and it should be avoided. Children find it
difficult to read large blocks of text, especially when the text
was written above their reading level. And the kids do not
have the option on that page to read the entire contents using
the arrow keys to move down.
Figura 6 – Site Kids Channel / Games
The Games page at the Kids Channel was not developed
properly. Thus, if the user is a child with the cognitive profile
learning Deductive-Evaluative (DA), the selection rule R15
will be selected by the GuideExpert system resulting sets of
guidelines suitable for child-user with AD profile as
recommended: presentation of the concept using figures
schema [7].
Analyzing the Kids Channel website, we selected seventythree
guidelines.
B. Analysis of the Website Government Portal of the State of
São Paulo
During the browsing on the Kids Channel website, we can
choose the option “Brazil Teaches”, where appears a link to
the “Government Portal of the State of São Paulo”. On this site
we analyzed the use of guidelines for the aged user, and if they
are in agreement with the recommendations of the HCI. When
we select the image we are directed to the “Government Portal
of the State of São Paulo” 2 as shown in Figure 7.
Figure 7 - Site Government Portal of the State of São Paulo
This page of the website is consistent with suggested
recommendations for aged-user. In the top menu there are
options to increase the font size, change the contrast and not
use commercial banners. According to the recommendations:
watch the size of fon ts, screen contrast and audio volume [2];
and the font size used in the texts should be at least 12 points
using buttons to increase and decrease the types, for example,
AA-A+, not to use banner advertising or auxiliary window or
animations. If these resources were used they should be in full
screen and the user must be able to disable them easily. Don’t
use icons, buttons, links and small characters.
Despite the good website presentation, the links at the top
menu are fixed and have too small fonts for elderly users.
After all many aged persons have some type of visual
impairment.
