Abstract:
1. An electronic device comprising: a display; a proximity sensor arranged near a display surface of the display and configured to provide an output signal corresponding to a degree of proximity of an object to the display surface, and also configured to provide a position of the approaching object in a direction horizontal to the display surface; a user interface control unit having a first operational mode and a second operational mode; wherein the user interface control unit, in the first operation mode, is configured to monitor proximity of a user's hand from the display surface based on the output signal of the proximity sensor, and when it is determined that the user's hand is within a first predetermined distance from the display surface, the user interface control unit changes a display state of the display and sets the second operational mode, whereas if it is not determined that the user's hand is within the first predetermined distance from the display surface, the user interface control unit does not set the second operational mode, and wherein when the user interface control unit, in the second operational mode, detects a position of the user's hand in a direction horizontal to the display surface within a detection target range in which a distance to the display surface is equal to or less than a second predetermined distance, the user interface control unit accepts the user's operation according to the detected position of the user's hand or a change in the position of the user's hand, whereas if it is not detected that the position of the user's hand is equal to or less than the second predetermined distance, the user interface control unit does not accept the user's operation according to the detected position of the user's hand or a change in the position of the user's hand, and wherein the second predetermined distance is less than the first predetermined distance.
