Design Thinking

Gamification of Chores

"For every task that must be done, there should be an element of hidden fun."

The design thinking or life attitude above can be applied to chores as well, which are generally considered not a favorable thing to do.

So, how can we find the hidden fun elements of the non-favorable things?

We Hate Washing Dishes

Nothing can be more disappointed when you are stuck from work and want to cook a nice dinner to bounce back, but find out there are dozens of unwashed plates in the sink. No worries, you are definitely not the only one who suffers from this. Based on research, 37% of the people in the US hate washing dishes!


Quarantine life is Hard

During the quarantine, everyone's mental health was affected more or less. For partners, the number of quarrels has increased to a certain extent, which is not conducive to the couple's cohabitation life and mutual feelings. In most cases, these quarrels occur in small things, such as washing the dishes, sweeping the floor, or folding clothes ... etc


Fun Observation

I cannot forget the night when I was washing dishes, and listening to k-pop via my phone. Since I was doing my project, I kept thinking about how to gamify chores in an intuitive way. I looked at the dishes on my hand meanwhile keep the repetitive radial motion of washing dishes. Suddenly, the image of the DJ spinning the discs appear in my mind. I realized that the motion of washing dishes is quite similar to spinning discs, and the bridge to connect those two behaviors is music!

I choose semi-transparent polypropylene as the package material, since it will make people be curious about what is inside, whcih is an interesting way to introduce a new concept design.



The best way to introduce a new design or attract new audience group is to allow them play around with it. And that is also my design intent behind this user experience center.
