Abstract
The invention relates to a portable digital device with an intuitive browsing function and an operating method thereof. A start unit is enabled to allow the value and direction of a gravity acceleration variation to be sensed. According to the gravity acceleration variation, a sensing signal is provided for a control unit, and then the control unit operates a user interface based on the sensing signal. Therefore, users are able to operate the digital device instinctively and obtain variable operating effects by varying the displacement.
