AN ELECTRICAL DEVICE WITH A SELECTED ORIENTATION FOR OPERATION

摘要

The present invention provides methods and apparatuses for configuring an electrical device to a selected orientation. Direction information that is indicative of the orientation of the electrical device is provided by a directional detection switch. A processor selects a selected orientation from a plurality of permitted orientations by processing the direction information and instructs a display unit to operate in the selected orientation. Different adjacent contacts of a directional detection switch are activated corresponding to different orientation of the electrical device. A conductive ball may be positioned by gravity and consequently conducts an electrical current between two corresponding adjacent contacts based on the orientation of the electrical device. A display unit of an electrical device may include an output component or an input component that is configured based on the orientation of the electrical device.
