Intro
MOOD
Another major resource was the Food and Behavior Research site
Second Edition: The Complete Guide to Eating Well and Feeling
http://www.fabresearch.org/81. As well as many well know medical
Your Best. By Elizabeth Somer, M.A., R. D. and The Food and
websites such as webMD and Mayo clinic.
Mood Project. Founded in 1998 by nutritionist Amanda Geary.
Personas
FOOD
This concept was largely based on the book Food and Mood:
Marvin B Wallace 19yr

Richard ‘Dick’ W. Hoffansted
Comfortable with the technology Busy lifestyle Wants to improve her mental health Wants to stop feeling tired and rundown Compare mood levels before and after meals
Has no prior experience with a smart phone but is slightly above moderately tech savvy Has not ever monitored food consumption or worried about healthy eating before Doesn't want to be depressed anymore
26yr
Comfortable recording data Can use a smart phone Lose weight by making better eating choices See his eating patterns Become more aware of ingredients
Phase 1: research and development
Phase 2: usability study
This study is to build a tool that would help people see the correlation between the food they ate and their mood.
Five different users participated in my study that matched with my user personas. An initial prototype with a medium fidelity design was created so the app could be tested on an iPhone.
Limitations
This screen is displayed after you log your mood so you can see what you entered.
Interactive graph that shows your mood levels though out the day from before and after a meal.
The navigation was moved to the bottom for more comfortable navigation with users thumb. When scrolling is needed a parallax effect allows the Nav to always stay in place with content falling behind.
Food can be searched for in the data base or scanned in with a label. The Hierarchy of this area was not as clear before.
1. Slow response time of the prototype software. 2. Noticeable delay in may spots. Comfort with Technology Computer
Tablet
Smart Phone
1 Least Comfortable
The ingredient page not only lists out all the ingredients but it will red flag any potential known culprits that may negatively impact the user. For instance if someone frequently gets migraine headaches the ingredient MSG would be flagged as a possible trigger. The same principle would apply if you had a food allergy recorded in your user profile.
While creating an account more information is collected to allow for a more robust interaction.

Project Goal: Individuals can improve their emotional and mental health by becoming more self aware of their eating habits and how mood is linked to food consumption.

Task 4
1. Tracking different additives or ingredients that might be triggering chemical imbalances in the body or interacting with medication. 2. Track medication and provide an ingredient brake down with the pros and cons of a given food based on the individual user profile. 3. A quick suggestion guide to make suggestion of foods to eat to help with specific issues. These added features expand on the main feature of tracking food consumption and mood correlation.

Also available is a list of things to watch out for based on your user profile. For instance if you are taking blood pressure medication grapefruit juice will interact with the proper absorption of the medication into your system.
After you search for or scan a food it brings you to the nutrition page where the pie chart shows the main nutrients in the food. Below and accordion allows you to see the ingredients and full nutrition. Then you can add it to your food log.

All of my users owned iPhones or were very familiar with them however two of my users very recently switched from older phones to the iPhone. Having never previously owned a smart phone they were unfamiliar with the use of a touchscreen phone.
Top Points Observed During User Testing
Original Design
Revised Design
Original Design
Revised Design
1. Hierarchy of buttons needed refinement 2. Hit sites were too small 3. Architecture of the site was sound and no one had issues navigating

New Owner Of Smart Phone / Not Familiar
Know How to Use Smart Phone
Phase 3: Improvements And Redesign Based On Review And Usability Study If time had permuted a new IRB would have been submitted with an additional user test on the new design that incorporated the new features. I also enlarged all the type sizes and hit sites for improved usability.
Improvements 1. Hierarchy and clarity in the design. 2. More contrast from the monochromatic design 3. Round out the new features and expand on them.
