Abstract: The present invention relates to the field of human-machine interactions and discloses an information processing method and an electronic device so as to address the technical problems in the convention that it may be time-consuming for the electronic device to receive an entry operation and the electronic device may respond to an improper entry operation. The method is applicable to an electronic device with a display unit on which there are displayed N target objects, wherein N is a positive integer, there is a display parameter for each of the target objects, there is an initial value for the display parameter of each of the target objects, and the display parameter is configured to determine a display size of the target object, and wherein the method includes: determining M target objects and K target objects among the N target objects according to a preset rule.

Abstract: A plug-in power supply wherein the mains plug unit is exchangeable in the form of a conversion plug system. The plug-in power supply includes a housing having a voltage transformer module for converting a mains voltage into the required low voltage, and an exchangeable mains plug unit with at least two mains plug pins. The plug-in power supply includes an exchangeable mains plug unit, and the housing includes at least two spring contacts which are electrically connected to the voltage transformer module. The mains plug unit includes at least two contact pins which cooperate with the spring contacts so as to establish an electric contact with the mains plug pins, and each contact pin is arranged in a separate recess.
