Confidential project, visuals are limited.
Aim of the Project 
Simplified UI project was initiated by our team to explore a simple and easy to use way of whitegoods, by eliminating the functions that are not used by users and highlighting the most necessary ones. 
My role was to design a simplified user interface for washing machine. I created the concept based on previous user research insights about users’ laundry habits.​​​​​​​ The outputs are confidential, here I will explain the process of prototyping & testing process.
Proof of Concept / Prototyping
We wanted to test our designs; but the first challenge was to create a prototype for a physical interface. We collaborated with a design & prototyping agency in Amsterdam.
I created the digital prototype and user scenarios for the prototyping team and we made some design iterations together.
 We built the realistic prototypes to simulate the haptic feedback and the interaction as in the real product.

Neuro- eyetracking test

User Testing

After getting the prototypes, we organized the user testing. Our user testing method was  a combination of think-aloud usability testing and neuro - eye tracking. With neuro eye-tracking, we aimed to mesure users’ first impression of interacting with our concept design compared to benchmark products, which they use during the test. 
Because of the new and technologic look, users EEG signals showed that before using the product (at the first look) users feel a hesitation if they are able to use it or not.
A short learning curve gains importance in ‘simplified’ user interfaces.
