I have tried to narrow my have my ideas into two categories

1) looking at how to educate young children who cant express or understand their emotions and stress levels my visualising them in a simple, playful, interacticve and responsive way. so maybe a toy design with a stress sensor which responses on a sliding scale (analog) and produces a highly visual/phyical response in result of the stress levels. ideas linking it with music with bmp in line with the level or in juxtaposition to calm down.

2)finding a fun, light hearted and interactive way to educate and inform health and weight, maybe using a pressure pad to weigh people and produce response accordingly. either in the home, linking it to the fridge  or 'cookie jar' with ideas branching out into the link between stress levels and unhealthy unnecessary comfort eating; or a public space of interaction.
