[Week13_Final] Prototype3, pecha kucha PT

IMG_9960Elevator Pitch : I am studying user experience design and physical computing technologies that can reinforce the formation of good habits for children aged 4 to 6. I found this falls in the larger domain of children education and behavioral psychology and based my work on the recent (2012) book about the habit cycle by Charles Duhigg. I involve the parents with the habit cycle by displaying the progress the child makes on a website. Parents are also the keepers of the rewards and set new goals for the next habit that needs to be learned. In addition, I want to understand how to make a wearable device for young kids that help them develop self-control ability, self efficacy and other positive traits in early childhood.

[Week 13_Final] User Scenario, User Stories



To articulate the user guide and specify the user flow of my project, I wrote down user flow of some example tasks, started from a simple habit like drinking water.



Also, I imagined the ideal use of this product in users’ daily life.

My product should be controlled by parents at first because they will educate their children by giving a direction and instruction how to use this properly. Also, parents will manage overall process of habit formation of their child. It will create a meaningful interaction between the parent and their child and enhance their relationship as well.




My ideal user stories.





[Week13_Final] Prototype 2 & Problem-solving

I solved some expected user experience issues of my prototype by adding physical computing works and adjusting the code !


  1. Now, all LED lights turn on in sequence and those are remaining when the other LEDs turn on. So, users can count the number to keep on track.

But I’m still figuring out how long the delay should be.





I had been working on stopping the repeated recording of the button. From my first user testing, the expected problem was when children continue to push the button at random. To prevent children from pushing button recklessly, I set a time delay. So, even if kids randomly push the button regardless of the actual behaviors, the led lights will not react to it.




Finally, the motor works when all the LED lights (8 LEDs) turn on !


So, now physical computing works are done!! 🙂


To polish my final prototype, I’m going to use laser cutting and I’m developing on the website as well.
