The poster on the pillar was more successful than the poster on the door as the pillar was placed somewhat central as you walk out from the stairs. Instinctively you look at the pillar so that you don't walk into it and the fact we placed it at about head height would ensure that's it's seen. We are happy with the changes we made to the design as a result of the feedback from other students, the larger font helped the text stand out at further distances and the darker blue on the sinking ship made it stand out especially under a dim light. We also interviewed some of the people who looked at the poster and asked them if they were from Dorset in a attempt to see if citizens of Dorset are more likely to interact with the poster rather than people who aren't, however the the results were roughly the same so no trends could be identified through that line of questioning.
Here is a floor sketch which illustrates the flow of people in and out of the foyer which also shows where we placed our posters and the areas with the most traffic. As you can see people mostly moved in between the two pillars and close to the Coste area.
From analysing the flow of people I would say that the screens closest coste would be the ideal place to have my interactive display as the display would likely be spectated by people waiting in the Coste queue and therefore might influence the people spectating to interact with the display themselves.
