Joe Eats a Rainbow

At lunch the next day, Joe keeps his eyes open for red vegetables. Because his goal is to complete the challenge, he doesn’t even realize that he would normally walk right past the vegetables.

That evening, Joe enters the vegetables he ate during the day into the website. His Vegetable Rainbow Meter displays his progress toward eating a whole rainbow, and gives him extra points for completing the challenge.

Joe is a typical Stanford student. He knows that he should eat more vegetables, but somehow he always ends up eating fried foods and soft drinks. Joe wants to change his eating habits for good.

One day, Joe discovers the Eat A Rainbow Challenge. He sees that Eat A Rainbow will help him get a balance of vegetables into his diet and let him track his progress.

After signing up, Joe receives his first vegetable challenge color. Joe can get extra points for eating vegetables of this color.

Joe realizes that he has finally managed to start eating vegetables. He can’t wait to complete his rainbow.

Prototype of Eat A Rainbow

• The Vegetable Rainbow Meter (left) shows the user’s progress in consuming different colors of vegetables• Users will receive emails (above) telling them what the next color Challenge is

Features/Functionality

• Users sign up to participate on our website• An email is sent every evening to all participants,

informing them what their Vegetable Challenge color is for the next day and asking them to record their vegetable consumption for the current day

• The user’s progress toward completing his rainbow is reflected by the rainbow diagram on the website. Each color of the rainbow is a progress bar for vegetables of the same color. Users make extra progress if they ate the Challenge color for the day

• The five users who have progressed the furthest on completing their rainbows are displayed in the Top 5 Leaderboards

Theoretical Justifications

• College students are a great audience because of their access to dining halls, which provide a wide variety of vegetable options.

• The daily Challenge color provides motivation to seek out vegetables that day, and adds an element of fun because of the bonus points you receive for finding it.

• Displaying the Top 5 leaderboard adds a social element to the Eat A Rainbow challenge, as users can see who’s in the lead and try to compete to be at the top of the list.

• The web-based nature of our design allows anyone, anywhere to take the Eat A Rainbow challenge.

Plan for User Testing

• Users will be recruited from at least two different Stanford dormitories

• Users will be asked to create an account on the website and participate for at least 10 days

• The website will track users’ progress and record their participation

Shortcomings of Design

• One possible drawback of the concept is that users may forget about the daily Challenge color, and therefore not eat vegetables on that day.

• Smaller dining halls may not have a wide variety of vegetables

• Participants may lose motivation if they struggle to find the vegetables, or if they just get tired of eating them

Expansion - What else is possible?• Other form factors or ID possibilities

o The website interface could be ported to a Facebook application, to increase the visibility and virality of the Eat A Rainbow challenge

o Text messaging could be used in place of email reminders in an attempt to target the times when users are actually eating

• Other features and interactionso The competitive aspect of the interface could be increased by

allowing users to view other people’s rainbowso The system could add bonus points or virtual trophies for

various feats – eating a rare vegetable, completing your first rainbow, eating 5 different vegetables in one day, etc.

o The website could support the ability to upload pictures of the various veggies people find, or allow users to make comments on each others’ progress

o We could communicate the health benefits of the various colors of vegetables to our users

Next Steps in Design Process

• The website must be implemented, including front and back ends. A simplistic design will be used for the first version, with an emphasis on an appealing rainbow progress meter.

• Users must be recruited; we hope to enroll students from a few different dorms on campus, to sample a variety of dining halls
