A PUBLICATION OF ACM SIGMOBILE
Mobile Computing and Communications Review
GetMobile is the new incarnation of the quarterly ACM SIGMOBILE Mobile Computing and Communications Review, which was formerly known as MC2R. GetMobile is the premier forum for addressing networks, systems, algorithms, and applications that support the symbiosis of portable computers and wireless networks.

Controlled Studies Outside of the Lab
Khai Truong
Often, evaluators study a computing system inside a laboratory setting to best gain an understanding of the effect of the system when different factors are manipulated. The laboratory setting allows evaluators to create not only the environment, but also the scenario in which a user study of system is conducted. Thus, the laboratory setting allows evaluators to control possible confounding variables and to develop insight about the cause-and-effect of the system when they manipulate specific usage factors. For example, it is clear that people often use mobile devices while walking. Thus, a laboratory study can be designed to test how well users might be able to interact with a mobile device while walking on a treadmill machine. Such a study, because it is conducted in a laboratory setting, would allow the evaluators to control the speed at which study participants would walk while using a mobile device, without fearing that participants must also pay attention to traffic or could be distracted otherwise.
Prototyping Capacitive Sensing Applications with OpenCapSense
Tobias Grosse-Puppendahl, Andreas Braun, Xavier Dellangnol
OpenCapSense is a prototyping platform to develop innovative applications that rely on perceiving humans with electric fields. Despite today's use of capacitive sensing mostly as a method to detect touch, it offers many interesting facets that range from mid-air interaction to contactless indoor localization and identification. The platform provides active sensors to detect human interactions at distances of more than 40 cm, by generating electric fields. Passive sensors allow for measuring changes in electric fields that occur naturally in the environment, enabling detection distances up to 2 m.
