CoSMiC

Abstract

Finding a missing child is an important problem concerning not only parents but also our society. It is essential and natural to use serendipitous clues from neighbors for finding a missing child. In this paper, we explore a new architecture of crowd collaboration to expedite this missioncritical process and propose a crowd-sourced collaborative mobile application, CoSMiC. It helps parents find their missing child quickly on the spot before he or she completely disappears. A key idea lies in constructing the location history of a child via crowd participation, thereby leading parents to their child easily and quickly. We implement a prototype application and conduct extensive user studies to assess the design of the application and investigate its potential for practical use.

A Review of Mobile Crowdsourcing Architectures and Challenges: Toward Crowd-Empowered Internet-of-Things

“…Consequently, participatory sensing can leverage human intelligence by enabling users to transparently contribute to complex and novel problem solving. This type of mobile crowdsourcing applications, such as Transafe [15], SenseCityVity [16], IncentMe [33], CoSMiC [19] and CrowdFound [20], requires human abilities, specializations, or skills of participants.…”

In [19] and [20], they propose the mobile crowdsourcing methods that allow mobile users disseminating information about missing people/items and then send notifications to others who are close to where the people/items lost and immediately after they are discovered, the locations will be determined.…”
