Briefing
The purpose of the application is to create a better
system than the “lockout” feature found on most cable TV systems. The new application is used on the TV itself,
and helps parents control what TV channels their children can watch. The application also allows parents to specify
what type of program content should be blocked, how much TV children can watch
each day, and during what time zones children are restricted from watching TV.
Parents create a password to be able
to set up the system. This password is a
security feature so that children cannot change the system settings. When setting up the system, parents create a
kids channel menu, which has the channels they want their children to be able
to access. When kids want to watch TV,
they select a channel to watch from this menu.
At that point, the system automatically performs all the checks that
parents have set up. The system makes
sure the program content is not blocked and that the current time is not a
restricted viewing time. The system also
keeps track of how much TV has been watched, and shuts off when the limit set
by parents has been reached for the day.
Parents also have the ability to
disable the system, so that they can watch TV without any restrictions. When parents are done watching TV, they can
set the system back to “kids” mode.
Scenario
Tasks
(1)
Set up the system to allow three channels
for your children to watch: channel 2, channel 4, and channel 195 (NESN).
(2) Set up the system to place these
restrictions on your children’s viewing: set a maximum of 4 hours of TV time
per day, block access to programs with violent content, and do not allow
children to watch TV between 3PM and 5PM.
(3) It is 8PM and there is a violent
show on channel 4. You want to test the
system. See if your kids would be able
to watch that show. Then, set the system
up into “parent” mode, so that none of the children restrictions apply. See if you can watch the program now. When done, set the system back into “kid”
mode.
Observations
User
Test 1 Notes:
o
For task 1, tried
clicking on many different buttons on the front page to try to set up the
channels. Did not try to log in. Said that the available channels screen
should not appear as the initial screen that parents see. The first screen should just allow parents to
login and set a password, and go from there.
o
For task 1, after
checking the check boxes for the 3 channels, wasn’t sure what to do next. Eventually tried Exit.

Successfully
completed task 2.

completed task 3.
User
Test 2 Notes:
o
For task 1, this
user logged in. Said the way for parents
to login on the front screen should be to push one button called “Parents
Login” instead of the whole section there is now. When setting up the channels, got confused by
the buttons at the bottom of the screen.
Said there should be two buttons directly below the check boxes. One button called “Select All Channels” and
one button called “Unselect All Channels.”
Also, user did not like the “Exit” button because the user wasn’t sure
that system would accept the updates made.
Said there should be an “Accept Changes” button and a “Cancel Changes”
button.
o
Successfully
completed task 2.
o
When performing
task 3, wasn’t sure how to change channels.
Thought they would use an outside remote control. I told the user to use what is before them on
the screen as if it was a computer.
Then, the user pressed the “Watch” button.
User
Test 3 Notes:
o
User 3
successfully logged in. Set up channels
correctly. Did not like the “Exit”
button because they felt they would exit the system entirely, which is not what
they wanted to do. Said there should be
an “OK” button instead, which would accept changes, and leave the sub-screen.
o
This user also did
not like the “Exit” buttons in the sub-screens.
User said they all should be replaced by “OK” buttons. Said the “Exit” button on the main Parental
Controls screen should say something like “Exit Parental Controls.” User was confused by the term “time
zone.” This phrase reminded the user of
Eastern Standard Time, or Pacific Standard Time, etc. User said should instead use the phrase “Time
Frame” to refer to a set period of time lasting from a specific beginning time
to a specific ending time. Also, when
the user set the time frame of 3PM to 5PM, the user did not check off any day
to apply it to. User was confused by
that part of the screen. User said there
should be an error message which tells the user to check off which days of the
week to apply the time frame restriction.

User successfully
