Our goal was to enhance the interaction between the pin pad machine and humans. We came with a new concept, making the interaction easy, intuitive and beautiful.
The whole team was involved in the research part and the concept. My main role in the team full of Ux Designers was to create the working prototype. I used Action Script 3.
We started the research by observing the purchase process. We saw that transactions with a pin pad were inconsistent, making it difficult for users to operate it. With these observations, we created some notes on how our pin pad machine needed to work.
Part of the teamwork on the product design, another part with the sound creation, but I was responsible for the prototype, being more involved with the interaction and user journeys.
I sketched the different paths of the journey in a diagram:
