Sparkle case study


How can children have fun when they are brushing their teeth?
This interactive game app helps children to brush their teeth for two minutes twice a day with songs they like.
The child creates a fairy that acts as their guide. After brushing their teeth
with their personalized fairy, they get a reward sticker to stay motivated. 


Visual research


I searched for what teeth brushing videos tried to convey most, and what issues they were trying to get across to children. 




Based on my research, the rough thumbnail sketches and information architecture werecreated.



Information architecture

I wanted kids to get a sense of toothbrushing as something enjoyable and not a chore. 
I created the information architecture with words that they are most familiar with.




Revisiting my experiences when working with children as a volunteer in NYC,
I created personas for children who would be four to six years of age and the personas of the parents raising those children. 


I believe putting yourself in the perspective of the user is key when creating an app.  
I created personas and empathy maps of users to make the interface efficient and easy to empathize with.
The empathy map helped me to add features like the reward systems and map
where children can compete with their friends for the reward stickers.



The selfie feature was added during the wire frame sketch phase,
based on research that I found that recording selfies while brushing can improve oral health.
