Target Audience
In conjunction with our Concept Brainstorming, we decided to focus on people with weight issues, not necessarily those who are already considered obese. This decision not only expanded our target audience, it also reframed our solution as a tool for the prevention of obesity.
We also identified a characteristic commonly identified with people interested in new technology, that of the "early adopter". This type of person is interested in trying new things and serves as a potential entry-point to market acceptance.
Anecdotally, a person with this characteristic might be seen trying the latest, strangest diets (The DaVinci Code Diet for example), but perhaps this behavior could be directed towards lasting solutions.
