Redesign of the cell
phone
In order to make it
safer for the user,
add sensors around
the cell phone to
detect obstacles
and warn the user

Jogging or running
device
Used in complete
audio; speaks any
text body
Sync to cell phone;
speak text messages
Still able to play
music and video

Prototype A Sketch
Prototype B Sketch
Prototype A
Scenario
 User
is on
Facebook
responding to
someone’s status.
At the same time
an obstacle, bike
rider, is fast
approaching the
user.
Step 1:
Task Flow
User opens Facebook app by tapping their
touch screen
Step 2:
User Reads friend’s status
Step 3:
User taps comment box to respond and taps
letters to type.
Step 4:
A warning box pops up onto the phone’s
screen alerting user to on coming obstacle.
Step 5:
User is able to avoid obstacle from the alert.
Prototype B
Scenario
 User
is jogging and
receives text
message while
listening to class
notes. User
responds to text
message while
continuing to jog,
hands free.
Step 1:
Task Flow
Device interrupts what the user is currently listening to
and reads an in-coming text message
Step 2:
Device asks user if they would like to reply, user presses
left thumb sensor to say “yes”.
Step 3:
Device asks user to speak their message. User
responds. Device senses message is done when no
longer hearing a voice.
Step 4:
Device asks if user would like to hear their message.
User presses left sensor for yes. Device reads back the
message. Device asks if user would like to listen again,
user presses right sensor for “no”.
Step 5:
Device asks is they would like to rerecord. User presses
left sensor for “yes”. User re-records. And is re-asked
questions in step 3-5, and responds with right sensor
“no”. Device asks is user would like to send, user presses
left sensor for yes and returns to audio.
Usability, Part 1: Preliminary Survey
 Before
deciding which prototype I design,
I made a survey to see what the users’
needs were in relation to prototype A and
B. I only asked three simple questions to
keep get a quick view and a variety of
answers. These questions were also aimed
to generate answers that would give me
the information I needed to choose
between my prototypes. I had 5 people
take the survey, persons A-E.
Usability, Part 1: Question 1
 What
would you not do while running,
jogging or walking that you wish you
could do?

A. Class assignments / homework
B. Eat or watch TV
C. Text without spelling errors and
Homework
D. Homework
E. Use both hands

What are the downsides to an IPod?
A. Get sick of your songs if you listen to
them too much
B. The headphones hurt my ears
C. Batteries die so fast & paying for new
music
D. Same thing as IPhone, but with no texting
so why not just get an IPhone?
E. You drop it and break it easily. (wear it on
your wrist!)
Usability, Part 1: Question 2
 3.
What are the downsides to a cell
phone?





A. Running into obstacles while texting
B. Paying a data plan and detaches you
from society
C. No Buttons!
D. Less face to face communication and
paying attention to one’s surroundings
E. Radiation, cellular data, bad
connections, broken Wi-Fi, unexplainable
drops
Usability, Part 1: Added Suggestions
 User
D: Suicidal wrist sensor; senses injury
on user’s body.
 User E: Holograms
Usability, Part 1: Conclusion

My first question
specifically let me know
what people wish they
could do while they were
mobile. The majority of my
answers pointed me
toward Prototype B which
can allow a user to do
one type of homework – a
reading for classes.

The second and third
questions asked the
downsides of mobile
devices we already use.
From this I have decided
which features to include
in Prototype B: texting
(phone & Facebook /
Twitter), satellite radio,
wrist or arm band or clip,
and paper composer.

“Jogging Device”

Usability, Part 2: Wireframe Testing
I
printed out my wire frames and gave a
series of tasks and asked a series of
questions to both my parents. My dad is
very technology savvy when told how to
use the device. My mom has minimum
exposure and use of mobile devices.
Usability, Part 2: Changes
 When
asked, “Where
would you go to send
a Facebook
message,” user was
unsure and hesitant
to choose “Texter”
because the user
considered that word
to refer solely to cell
phones.
Usability, Part 2: Changes
 The
device will operate on voice
commands instead of thumb sensors.
When asked to use the thumb sensors, the
user testing the device asked why
wouldn’t they just verbally speak yes or
no, since they were already verbally
composing text messages.
