Systems and methods for detecting device orientation use two motion sensors arranged perpendicularly to one another require, one horizontal (landscape) and one vertical (portrait), to automatically detect orientation of an electronic device. The motion sensors operate mainly to detect and notify the device of any motion in proximity to the device, but the perpendicular positioning additionally allows the sensors to be used for autodetection of device orientation. The sensors detect movement near the electronic device such that one of the sensors will detect the movement more strongly than the other sensor, depending on whether the device is oriented horizontally or vertically. The stronger detection by one of the sensors can then be used to provide an indication of the device orientation. Such an arrangement avoids the need for gyroscopes, accelerometers, or other components designed to detect position and orientation.
