Methods and apparatuses for operating a portable device based on an accelerometer are described. According to one embodiment of the invention, a movement of a portable device is detected using an accelerometer attached to the portable device. An orientation of the portable device after the movement is determined based on movement data provided by the accelerometer. It is determined whether the portable device is held by a user after the movement based on the movement data provided by the accelerometer. Locations of the hands of the user for holding the portable device are determined based on the orientation of the portable device. At least one interface that is not within the predicted locations of the hands of the user is activated.
