  • Our creation is called “MEGAN” Which stands for Matriculating Good Nutrition. Why matriculating? Yes, it actually makes use of your matric card!
  • An integrated nutrition monitoring system that tracks the daily consumption patterns of users and uses peer motivation to encourage healthy eating through the use of a social network, and an avatar projection of the user’s body. Objective: Basically, to overcome the barriers to healthy eating through peer motivation and visual goal settings.
  • People: NUS students who stay in campus; demographics include teenagers, concerned about body image, highly influenced by peers, tech savvy, Activities/Context: Choosing and deciding what to eat on campus, making decision which are highly influenced by who you are with, length of queue etc. Technology: Available tech requires users to manually input food items which can be quite tedious. Current technology assumes users already have the desire and actively want to record down their daily nutrition intake.
  • Note: “Scenario serves to identify the problem statement and show how our design will be a solution to the issues identified.” This is Kayla a an image conscious student staying in hall. She goes to the canteen with her friends for her meal and makes the oh so common question of “what should I eat?” Kayla makes her choice based on What her friends planned to eat, Which store has the shortest queue or What she feels like eating More often than not this is what she will end up ordering: nice and golden brown and delicious on the plate, with no or minimal vegetables. When she goes back to hall for her meal, she ends up wondering “What have I eaten for the day?”, “If I continue doing like this is it going to have any effect on me?” And even when she remembers what she has eaten, she has no other additional nutrition information. And she ends up giving up, cause there’s no motivation at all for her to control her diet.
  • Key points derived from scenario: Technology needs to seamlessly fit into the student’s everyday purchase of food and minimizes the extra work that goes into most of today’s nutrition tracking devices. Eating is after all a social activity , and decisions made by the individual are largely influenced by his or her peers Students need motivation to change. It is not easy to track their nutritional intake or change their eating habits. There has to be a motivational factor behind to drive them to do so. And friendship clique is critical as a source of motivation! EXCESS INFO Our group believes that NUS Students who are still young and healthy are not so much affected by information about how healthy eating will be beneficial to their health or will help prevent diseases etc. Instead our group believes that what can really drive teenagers to change their eating habits are these two factors: Body image & Peers More than 90% of girls want to change at least one aspect of their appearance, with most of them picking body weight. Almost 25% would consider plastic surgery to fix perceived flaws, and 13% admit to having an eating disorder. “I believe that poor body image is fairly widespread,” says Elissa Gittes, MD, an adolescent-medicine specialist at Children’s Hospital of Pittsburgh. “The media evokes ideals to girls which are often unattainable and unhealthy.” friendship clique is an important sub-cultural environment for an individual teenage girl, and there seems to be a very close relationship between a girl’s body image and dieting behaviours and those of her friends. It is likely that this culture reinforces particular weight related attitudes.   National Eating Disorder Information Centre ~ 200 Elizabeth St. 7ES-421, Toronto.ON. M5G 2C4 www.nedic.ca sub  
  • (Tra’s flowchart will be the cue for the speaker to talk about the conceptual scenario.) What does MaGn do? She records what you eat very easily, no extra typing, just tap and go She links you to your friends so that together, you can encourage each other to eat healthily Plus, she engages you so you’ll return and continue with the progress.
  • So what happens? Firstly, when user signs in to the online portal for the first time, he/she will upload a photo of him/herself and enters the Age Gender Height Current Weight Desired Weight and a virtual avatar of the user's current state will be generated. A virtual avatar of the user's desired state will also be generated as a visual goal. Whenever a user buys food from a canteen or eats from the dining hall, he/she will scan the matriculation card. The price and nutrition information will be pushed to the user’s online portal. The system will automatically doctor the current virtual avatar as and when. The user will be able to check out his/her progress through this portal.
  • Kayla as an example At a Glance: Gives the user a quick over view of her progress. How far away she is from her goal? IMPORTANT point: the virtual avatar of Kayla will reflect the healthiness of Kayla diet A healthy diet with loads of fruits and vegetables will translate into an avatar that is healthy looking; if not, recommendations of 2 + 2 are made. The social and peer element: Friends' Page: Check and compare how others are doing, and what are your friends suggesting you to do.
  • How feasible is MaGN? As MaGN uses the matric card/ez link card to track what you consume, it is a highly feasible form of design. Plus, in terms of the online portal, it taps on existing platforms similar to those of facebook.
  • EVALUATION. The strengths of MaGN include the following: It is seamless. It reduces the labor intensiveness of data entry unlike most nutrition tracking devices/apps today, because it uses passive ambient technology. MaGN also reduces inaccurate self-reporting, either intentionally or due to cognitive biases. -MaGN can be easily implemented because the technology needed to create her already exists! (REMARKS: Pls copy & paste the picture of the black box “thing” that scans matric cards at halls) -MaGN emphasizes on motivation and encouragement by friends to encourage healthy eating. Hence there is always an element of engagement as the system incorporate elements of identity and immersion. - Appeals to the tech savvy generation such who are adept in online social networks
  • The weaknesses of MaGN include the following which of course can be improved on: - The issue of privacy and acceptability. Do I want other people to know what I am eating all the time? (Solution: Allow for a privacy function that only friends can view) -Is there continuity after ‘fun element’ is removed – (need for longitudinal study) - Serving sizes?: Hard to give a very accurate amount. (May need to take into account customized proportion foods) -Plan may backfire – will users treat it more as a game and fool around, thus destroying the original purpose of why MaGN was created. (Include some game constrains to prevent erroneous entry) -How much of what your friends say online translate into real actions?
  • Magan is not just about healthy eating. It’s about intelligent eating. “ Are you on MaGN” The End.
