Just a short note, linking to an article I read (on Christmas Day apparently) about using mobile phone data to analyse crowd movement in Hyde Park. This wasn’t real time, but based on historical data from provider EE. The comments suggest many think of it as an invasion of privacy, despite being anonymous and not real time. It suggests that they could be popular resistance to heritage sites using the technology, especially if using it in real time.
Alternatively, Dr Suzy Moat, in Jim Al-khalili’s radio programme, Putting Science to Work, made the case for using mobile photo data to monitor crowd movements and save lives by preventing panic/crush disasters such as Hillsborough, and those that that occurred in Mecca during the Hadj.
So I’m not discouraged from experimenting with the technology and testing users’ reactions to the privacy/benefit equation.
