The question: How to get users to give up that data? Researchers at the New Jersey Institute of Technology tested two incentives: gamification and micropayments. The test involved building a campus Wi-Fi coverage map using user data collected from student participants who either played a first-person shooter game or who were payed to complete certain tasks (e.g., taking photos). The game turned out to be a quick and efficient way to build the Wi-Fi coverage map. But data from the micropayments group was found to be 'sometimes unreliable, and individuals were trying to trick the system into thinking they had accomplished tasks.'
