I am not sure surveying current smartphone users, especially in countries where smartphone penetration is still low, is the best way to gauge the demand for smart-city services, but it is a useful input. Here are some key findings from an Ericsson study that is available on the web. The report – which surveyed over 9,000 smartphone users in nine cities (including Beijing, Delhi and Tokyo) – found that 76% of respondents would use traffic volume maps, while 70% would use energy usage monitors and 66% would use apps to check water quality. “These are services that consumers will expect cities to make available via the internet,” says Michael Bjorn, Ericsson ConsumerLab’s head of research. Bjorn adds that demand for smart-city services could also drive future concepts such as interactive road navigation, social bike/car sharing, indoor maps, as well as healthcare concepts like heart-rate monitoring rings, posture sensors and a digital health network of medical data accessible by physicians.
