I focus on designing interventions that can change the personal shopping behavior to address the obesity issue. The previous draft proposal is designing a record system that can record/ present personal sugar consumptions in a week/month/year. The system is presented in supermarkets via self-checkout machine. The intention of this design is to showing people the ‘scary data’ of sugar consumption to raises alarm bells in their mind.
I received a lot of feedback from my tutor and my group about the draft idea. Unfortunately, this design doesn’t really work. And my tutor suggested me to come up with other ideas that not conventional. Also, he suggested me to think about the ‘tone’ of the design (do you want it to be entertaining or serious). After the discussion, I decided to think of some design ideas that is more engaging.
I drew a lot of mind maps to help me brainstorming more possible design directions. I firstly came up with designing a digital pad(looks like iPad) that installed in a shopping cart. People can use it to scan food products and get to know the ingredients more easily. Also, it will show healthy/unhealthy tips when you put food in the cart.
The second idea is the ‘healthy-eating challenge’. It is a challenge game that present online via website/app. People can take a 10 days/ 30 days challenge of trying a healthy eating habit. For example, there are 20 days of giving up chocolate challenge. Users can invite friends or family to join the challenge and also be a supervision.
The third idea is based on public advertising. The idea is setting digital mirrors in the snacks/sweet beverages area in supermarkets. When people go to buy unhealthy food, they will pass by the mirror. And the mirror is reflecting yourself, but in a ‘weight-gain’ version by surrounding various of snacks/sweet beverages.
I decided to develop the third idea further:
Project title: “Do you still want a chocolate?” ‘magic’ mirror
-smart mirror reviews possible body changes
Practice type: Service design
Personal responsibility plays an essential role in promoting the obesity epidemic. There are already a lot of online information or knowledge that suggesting healthy eating habit; they are easy to access via website/apps. However, a lot of people still seems to care less about dieting habit; they still shop unhealthy snacks because they think ‘well, one chocolate bar, not big deal’. Thus, the fundamental way to tackle the obesity issue due to bad eating habit, is to change people shopping habit.
The idea behind:
Every time we enter the supermarket, we are being manipulated. By design, all the fancy tasty snacks and sweet beverages are present at eye level, and will grab your attention immediately; and on the other hand, food like eggs, healthy cereal are put in the bottom. But could we be manipulated for the better? Design can nudge people a better direction toward food choices. There are a lot of research showing that advertising that included words like ‘healthy’, ‘low-sugar’ and ‘low-calorie’ caused people who were overweight or dieting to subconsciously buy fewer snacks. Seeing those words can remind them to choose eat healthily.
Remind people the shop wisely.
Help people to change people shopping behavior – stop buying unhealthy food.
