A data processing device may be operable to determine whether the data processing device is in a state of charging a battery. When the data processing device is determined to be in the state of charging the battery, a charging condition of the battery may be analyzed by the data processing device. The data processing device may analyze a viewability condition at a display module. The data processing device may analyze an environmental condition associated with proximity of a human to the data processing device. The data processing device may then choose, based on a result of the analysis of the charging condition, a result of the analysis of the viewability condition and/or a result of the analysis of the environmental condition, display of content in a manner to attract attention to the data processing device.
