Abstract
Mobile crowdsourcing applications leverage volunteers to collect information using their personal devices. It is hence vital to foster the volunteers' engagement and their contributions to ensure the long-term viability of these applications. A method to reach this goal is to notify participants about new tasks in their physical proximity. Such location-based notifications can however impact the users' experiences, disclose their location, and/or incur additional resource consumption. In this paper, we therefore investigate the potential worthiness of introducing location-based notifications in the wild. Our analysis includes the perspectives of both potential users and campaign managers. To this end, we have conducted two questionnaire-based studies counting 335 participants in total. By doing so, we gain insights about the participants' expectations and the value attributed to invested resources. We further identify significant factors that influence their readiness to activate this new function. Finally, we measure the impact of job alerts and rewards on both the quantity and quality of users' contributions. Consequently, our findings can help campaign administrators in the design of future crowdsensing applications.
