Thesis approach

I've been thinking about my thesis idea being multi-touch screens used for service and ads in Toronto. While this idea could still be shot down, I think it might be an idea to use it to see what I'm missing in general. I've only thought about the potential that this technology and system could provide a multi-cultural city like Toronto and a city that has a large amount of large billboard ads. I haven't thought about how long this project can last, meaning the entire 8 months of study, or anything else I have missed.
