Couplable Components for Data Processing in Mobile Sensing Campaigns

In mobile sensing, modern phones allow scientists obtain the information about the participants and their surroundings. At times, obtaining raw sensor data from mobile devices demands their collection through sensing campaigns. Often, processing these data requires data processing components in the mobile device. Some of the data processing components pertain to mathematical functions that can be reused to form other functions. These types of functions are usually crafted at a design stage by the programmers. In this work, we present a novel way in which components can be coupled at the design of the sensing campaign, without the need to redeploy the app. That is, scientists can couple two existing data processing components into a new, high-level component. The results of this paper can facilitate code re-use, code maintenance, and flexibility to a mobile sensing campaign.
