After the multiple research, brainstorm, and iteration of sketches, and receive feedback from classmates, friends, and professors, I finalized the product design of the problem that I wanted to solve. Based on multiple user interviews, here are some key goals about the product:
1. Simple, easy to read
Use huge San-serif font instead of the small serif font, to increase eye recognition.
Have enough information for the driver to check the car, such as the car speed, car fuel, direction steps, and coordinate.
3. Safety Reminder
The color on the left bar will be changed by the driving speed, when it's driving too fast the color will be changed to yellow then red.
After the product function is solid, I started to design the main features of the app. I have gone through several iterations of the app and user testings with different people and finalizing all the screen's feedback into the final prototype.
