Abstract: Disclosed is an electronic device that is detachably coupled to a frame of a head-mounted device that can be mounted on a head of a user. The electronic device can consecutively perform tracking of the user's head using a sensor, when sensor data is abnormally received. Thereafter, if the sensor data is normally received from the head mounted device, the electronic device can consecutively perform the head tracking, enabling the user's action and the visual information to coincide with each other, thereby reducing inconvenience or misoperation which may occur in the case of the conventional head-mounted device.

Abstract: A power supply includes a first and second switching node, a first power switch and a second power switch, and a first bootstrap capacitor, the first bootstrap capacitor including one end connected to the first switching node, a third and a fourth power switch, and a second bootstrap capacitor, the second bootstrap capacitor including one end connected to the second switching node, and a charge sharing circuit storing a charge using a power supply voltage, providing a first charge sharing path for the first bootstrap capacitor from the stored charge based on a first voltage charged in the first bootstrap capacitor, and to provide a second charge sharing path for the second bootstrap capacitor from the stored charge based on a second voltage charged in the second bootstrap capacitor. The first charge sharing path and the second charge sharing path include a common charge sharing path and overlap each other.
