Prototype APrototype B
Device Idea Summaries Prototype A
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
Prototype B 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 (does not show images of 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.
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.
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
Usability, Part 1: Question 2
2. 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.
Prototype B Named: “Jogging Device”
Features: Composer

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.
