In the remaining time of the tutorial, I spoke openly with Tim about the evolution of our idea and how we could represent this. I suggested using lights to represent the data; the higher the light beam, the more active the person, however Tim was not fond of this idea. We spoke about integrated living forms, which is where our group had started, and I mentioned how we were considering using fake fish a few weeks ago but eliminated this due to our then, elderly market. However, he loved this idea and I did agree that the novelty did suit our young and active target market. I put this forward to the group and they agreed that using the floating height of the fish to represent how active the person was was a good solution to work with. The technology was obviously going to be the hardest part.
So our idea at this stage was that each group member would wear a slimline heart rate monitor which would transmit this information to a sensor within the fish. Each fish would correspond to a different person and would have a distinguishing feature such as colour. The higher your fish floats the higher your heart rate has been on average. If you are inactive for a certain period and are transmitting a very low heartrate then your fish may die and you will have to reset your fish which may involve going to many of your friends houses and facing that humiliation. This could be used by a coach to keep an eye on his team, competitors and friends. Issues are the fluctuation of heart rate based on the individual.
