Astraea's story
Name: Astraea Gender: F Age: 14

Astraea loves drawing and playing PC games and watching animations. Her favourite PC game is the Sims. She enjoys creating new avatars and virtual objects in the game and share them in the Sims community.

Astraea likes to eat seafood and dairy products such as milk, yogurt and butter. She thinks her eating habit is quite healthy but she would like to know if she could eat healthier.

Astraea downloaded Crayon Cook to her computer. She likes it because she can draw her favourite food in the game. She has created many food items in her inventory.

"The fun thing is," she said, "you can use the ingredients in the game to create all kinds of food and check their nutrition information. I have actually created some new dishes that I've never had opportunities to try in my life. I always try my best to make them look beautiful, delicious and healthy. I've shared some of my food on Crayon Cookbook and my friends love them! That makes me very happy. Sometimes my friends will ask me to create some food for them, because I do it so well!"

"I didn't care much about the food or their nutrition information, and I didn't care much about what I'm going to eat for lunch or dinner."

"Now when I look at my food I automatically start to analyze its nutrition information using my knowledge. I will also think about how to make it more healthier if I were to create it in my game. I tend to avoid food that is not healthy because I really don't want to feed myself with junk food."

**Sue's Story**
**Number ** 1 **Title ** Middle School Student

**Description ** In this user story the game Crayon Cook and the website Crayon Cookbook are used by a 2nd grade student in a local middle school.

**Actor(s) ** Sue is a lovely 13-year-old girl who lives in Great Boston Area. As a 2nd grade student in Watertown Middle School, Sue is recently introduced the concept of nutrition in her science class. She learns a little about the basic idea of fat, calorie, vitamin, etc. which is truly boring to her. Sue likes biology and nutrition just OK. She can’t utilize the nutrition information and believes it meaningless to learn it.

Sue enjoys delicious food and is always willing to try different food. Last winter vacation, her mother taught her to cook her favorite dish. She was so excited and she dreams about preparing meals for her friends and family. “What if I can apply nutrition in daily life and combine it with my food!” Sue is also good at drawing and art class has long been one of her favorite courses.

**Scenario (Flow of Events) ** Sue is told by her friends that there is really cool stuff about drawing a healthy meal. She enters the Crayon Cookbook website. There is a video tutorial on the website page. Out of curiosity Sue clicks on the play button and watches the tutorial. She is soon attracted by the game, where users can draw whatever food they like to serve the guests. In the website, there’s also a gallery page where the food drawn by others are presented and commented. Sue is very excited about what others have done and can’t wait to download the app. Actually her parents have just bought her a new iPhone, but she doesn’t have many apps in it.

Sue downloads the Crayon Cook Game to her iPhone, enters the main interface, and creates her own account. Then she is led to customize her avatar. She is guided to choose the hair, dress, skin color and so on for her own avatar. Sue really enjoys this process and makes her own avatar quite like herself: light skin color and yellow long hair. She seems pretty satisfied with her look and enters the game, where appear four options: “New Game”, “Load Game”, “Game Help” and “Visit Cookbook”. Although Sue has watched the basic tutorial, she still clicks on “Game Help” to get a better sense of the rules of the game. Then she loads the game and finds herself in a kitchen where there is a big fridge. She presses the sticky note on the fridge. “Your friend Mr. Richards is coming to dinner. He is allergic to peanuts and has high blood pressure. Please prepare dinner for him.” Sue reads. Sue finds it helpful that she can look up the profile of her guest by clicking on the “Guest Info” button on the bottom of the screen. Sue tries to recall something about allergy and hypertension that she has learnt in class. Suddenly she finds the “Glossary” button beside the “Guest Info” one. She clicks on it and there is a detailed explanation of the symptom, points patients should pay attention to in terms of diet nutrition, and other basic information of the diseases. Actually Sue finds the explanation of words (such as fiber) in the “Glossary” helpful to her in understanding them.

Now that she has enough information, Sue begins drawing the meal. She is first asked to label the food she wants to draw. Sue enters “Pizza”, her favorite food. A window pops out asking Sue to also label the ingredients of the pizza, such as broccoli, mushroom etc., so that the system can compute the calories. Then she presses the “Drawing Board” button and uses the brushes to draw the food. Sue presses “Done” and a window pops out asking Sue to enter the quantity of the food. After finishing all the process, Sue can choose to add the food to the plate on the table. The “Nutrition Facts” table beside the plate shows the basic nutrition information of the food, which includes Calorie, Fat, Vitamin A, Vitamin C, Calcium, Dietary Fiber, Iron and Sugar. This table will always show the total nutrition facts in the plate. When Sue clicks on the separate items in the table, the information on the particular nutrient (such as Vitamin A) pops out. Sue can draw more than one dish or drink and add them to the plate. The score plate on the screen basically tells the user whether they are serving too much or too little nutrition to the guest. Besides the pizza, Sue also draws a bottle of milk and some fruits to the plate. She is careful in deciding the quantity and keeps calculating by herself. When she finishes the preparation process, she takes a final look at the nutrition table and presses “I’m ready to serve my guest” button.

On the screen both Sue and her guest Mr. Richards enters the dining room. Mr. Richards eat the food and it seems that he really enjoys the meal. He smiles and the conversation bar pops out “Thank you very much Sue! I enjoy the dinner and you did a great job in serving a healthy meal. Good job!” Sue is happy that her guest likes the food. She presses “Take a photo of my meal and add it to the gallery.” Now she can enter the gallery, on the wall of which are the meal she has just drawn. There is also nutrition information when she clicks on it. She can also share her meal in the website if she wishes.

Having finished the first level, Sue is ready to go the second and higher level. She also finds that she can customize the guests she wants to serve by creating new guest profiles.

Besides the Crayon Cook game, Sue is now excited to go the Crayon Cookbook website where all meal doodlers communicate with each other in the forum. There are also sections where they can share nutrition information and their own drawings. A more detailed information and tutorial page about nutrition and disease can also be accessed in the website.
