EasyHarvest aims to simplify the deployment and controlled execution of large-scale sensing applications on smartphones. On the one hand, application owners submit to a server sensing tasks for distribution on smartphones, and collect the data produced by them in a simple manner. On the other hand, smartphone owners control the execution of sensing tasks on their devices through a single interface, without having to repeatedly download, install and configure individual sensing applications. The interaction between the smartphone and the server occurs in a transparent way, with tolerance to intermittent connectivity and support for disconnected operation.

Just enter the id of the Sensing Task (found on the URL at the EasyHarvestServer) and the desired way of visualization (raw/orientation/map) depending on the type of data produced by the Sensing Task.
