While online crowdsourcing markets (such as Amazon's Mechanical Turk, CrowdFlower and oDesk) make it convenient to pay for workers willing to solve a range of different tasks, they can suffer from a number of limitations. For instance, these online platforms do not always attract workers of desired background or skills. Thus, it can be a challenge to recruit workers that speak a specific language or live in a certain city. Further, these online platforms are not ideal to collect information on the go (either passively or actively) or for tasks that require workers to be in a specific location. Mobile and situated crowdsourcing can help fill in the gaps where online platforms are suboptimal. This special issue aims to present a set of high-quality, high-impact, original research results reporting the current state of the art of mobile and situated crowdsourcing. Manuscripts must be original, but significant revisions of papers recently presented at conferences and workshops will be considered (at least 50% new material). We encourage contributions in the following key areas and considering a mobile or situated crowdsourcing context: * Applications: crowdsourcing applications that can benefit from being conducted using mobile or situated technologies as opposed to using online platforms. * Quality control and incentives: designing crowdsourcing applications that encourage truthful responses. * Methodologies: methods and methodologies used for gathering and evaluating crowd contributions. * Behaviours: understanding worker behaviours in these contexts. *Submission* Deadline: the final manuscripts are due February 15, 2016 but early submissions are encouraged. All contributions will be rigorously peer reviewed to the usual exacting standards of the IJHCS journal. Further information, including submission procedures and advice on formatting and preparing your manuscript, can be found at: http://www.elsevier.com/journals/international-journal-of-human-computer-stu... Manuscripts are submitted via the Elsevier Editorial System (EES) at: http://ees.elsevier.com/ijhcs/. It is important that authors select the article type "SI:MSC" when they submit their articles in EES.
