Safe Mobile Devices Designs Kristen Kuron JMA464; Dr. Gibbs Prototype A Prototype 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 Scenario  User is on Facebook responding to someone’s status. At the same time an obstacle, bike rider, is fast approaching the user. Task Flow Step 1: 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. Task Flow Step 1: 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

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  Create a document  Player  Audio from Music, Audio Books and Video  Reader  Reads PDFs, Newspapers, Text Documents, Magazines, etc.  Satellite Radio  Texter  Sync phone, Facebook, Twitter or any chat site to verbally text  Components:  Mobile Device  Headphones with recorder  2 thumb sensors  Cloths Clip  Arm / Wrist band

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.
