Having personally spent hours and hours on train journeys to various locations across the country, I've seen countless numbers of other travellers come and go.
I began to consider that if I was sitting back and observing all of these other people then some, if not all, of them must being thinking in a similar way about everyone around them. With this in mind I began to develop the idea of Perception Station. At its lowest form it could be considered an image sharing website. But I planned to incorporate the ability to allow each user to leave their own thoughts about each of the people tagged in an image, encouraging them to add information before being able to progress to more images.
The data that could be collected through such a site would be incredibly interesting to analyse for patterns and I feel would also act as a good indicator of the kind of stereotypes that are still commonplace today. Given the chance, I think that users could also be tempted to annonymously add an image of themselves into the colelction in order to see how they come across to those around them.
