Monitoring mobile device usage

Abstract:

A first image of a mobile device screen is recorded into memory of the mobile device. The first image includes at least one icon that represents an application installed on the mobile device. A second image of the mobile device screen is recorded into the memory of the mobile device. A graphical change in an area of the mobile device screen corresponding to a position of the icon is detected by comparing at least a portion of the second image to the first image. The graphical change results from a user selection of the icon to activate the application represented by the icon. In response to detecting the graphical change, determine an identifier of the application represented by the icon. Send a record of the user selection of the icon to a collection server. The record includes at least the identifier of the application.
