Designing the front door for a vending machine
I worked on this project when I was working for the product consultancy Kinneir Dufort. The goal for the client, Mars Drinks, was to integrate a digital screen at the front door of a vending machine.
Background and process
This client came to us because they wanted to add a touch screen at the front of the machine to guide the user through the process and to show information about faults in the system.
After mapping the process and designing the user journeys, I designed an interactive prototype using a big screen TV to show the real size of the machine.
We tested the prototype in the UK, German and French markets.
The research results were very positive regarding the interaction with the screen, but they showed problems with the front buttons. The information wasn’t clear so I redesigned them.
