A data processing device may receive, from an application running on the data processing device, an indication that one or more sensors may be associated with a user input for the application. Based on sensing information collected from the one or more sensors, a characteristic of the user input may be determined by the data processing device. The data processing device may refrain from entering a sleep mode if the characteristic of the user input matches a specific characteristic condition specified by the application. The data processing device may allow entering the sleep mode if the characteristic of the user input does not match the specific characteristic condition for a specific timeout period specified by the application. The data processing device may receive the indication, information on the specific characteristic condition and/or information on the specific timeout period via invoking, by the application, one or more application programming interfaces (APIs).
