Abstract
A gravity switch and a microprocessor are disposed in an electronic device having a virtual image display. The gravity switch provides a determination of the electronic device's orientation to the microprocessor. The microprocessor provides a display signal to the virtual image display based on the orientation of the electronic device. The microprocessor rotates the input from a display interface based on the orientation of the electronic device. The microprocessor includes a time hysteresis to prevent inadvertent changes to the image orientation due to momentary movements of the electronic device.
