As part of the TUI process we developed quick prototypes whose main purpose was to serve as communication tools for user validation. These quick sessions were held throughout the course of the idea development phase of the project and were closely tied to our initial user research phase by going back to the same people we had interviewed originally.
The most interesting thing about these sessions is the speed at which you can confirm and dismiss assumptions about the value of your design. In this session I took an idea for a chopping board abacus which allowed you to track your diet in relation to the food pyramid. The idea was that as someone is preparing food or having a snack they can self-track their intake, recording it daily and be presented with a simple analog visualisation at the end of the week showing the state of their diet. This turned out to be a bit of a failure. The user validation session ended up with me doing most of the activity for them as they were way to busy chopping, mashing and frying. People just don’t have the time or inclination to add another activity during their cooking time. What struck me most was how easy it was for me as a designer to overlook (and even sometimes ignore!) these truisms in favour of an ‘engaging solution’. Our dreams are not always shared.
The truth is that this process of user validation, or co-creation, or whatever you call it is a really integral part of an any design process.
