The main idea behind this design is to have a very simplistic layout with big button,big pictures, and simple flow.
This was focused on making the automation process as simple as possible. The idea was to have every item you buy, have the option to buy it on a regular basis.
For my extreme design, I decided to focus on an illiterate point of view. So I sketched out an interface made with mostly pictures. I was trying to be as visual as possible, because our interviews showed that the elderly enjoyed having a lot of big images.
