ToothFairy
Through varying prototyping methods–analog, voice user interface, and mobile prototyping– I created ToothFairy. This device is a smart toothbrush attachment that rewards healthy dental hygiene habits. It pairs with a mobile app so you can see how your teeth cleaning habits compare over time.

Prototyping
Prototyping played a large role in making this project come to life. This was done using analogue, voice user interface (VUI), and mobile prototyping.
ANALOG PROTOTYPING
The prototyping methods I chose will allow the user to test the entire flow of the ToothFairy experience. The analog prototype will act as the physical attachment to the toothbrush. Using construction paper and a laminator, I created a realistic, waterproof, and low-fidelity version of the ToothFairy device.

VOICE USER INTERFACE PROTOTYPING
The next prototyping method, VUI, will enable the user to hear what the actual device may prompt them during a toothbrushing session. I prototyped 3 different conversations for the user and ToothFairy: turn on ToothFairy, brush teeth with ToothFairy, and redeem Sparkle Points. Below are the task scripts as well as the dialogue/action flow.
Task 1: Turn on ToothFairy
Person: ACTION - Turns on ToothFairy device
ToothFairy: Hey! Let’s get brushing.
Task 2: Brush teeth with ToothFairy
Person: ACTION - Starts brushing their teeth
ToothFairy: You have started your brushing session.
Person: ACTION - User misses molars
ToothFairy: You might have missed your back left molars, you might want to give them an extra scrub.
Person: ACTION - After 2 minutes of brushing
ToothFairy: Congrats! You finished this brushing session. Check the app to see your session details and redeem your sparkle points.
Task 3: Redeem Sparkle Points
Person: Hey, ToothFairy!
ToothFairy: I’m ToothFairy, your teeth brushing companion. Start brushing your teeth to get started!
Person: How are you doing?
ToothFairy: I don’t think I caught that. Ask your question again or visit the ToothFairy mobile app for more answers.
Person: How many sparkle points did I get for my last session?
ToothFairy: You earned 98 sparkle points for your most recent brushing session. Way to go! To see your full sparkle point history, check the ToothFairy mobile app.
MOBILE PROTOTYPING
Lastly, the mobile prototype will allow the user to see how their toothbrushing data may be explored after using ToothFairy.
Showing off ToothFairy
To determine if ToothFairy would be a viable, feasible, and desirable product I tested my prototypes. Take a look at the video to see how it held up!
