Abstract
The invention is directed towards wearable devices and operating wearable devices in a visual mode when a display device of the wearable device is within a line-of-sight (LOS) of a user and operating the wearable device in an audible mode when the wearable device is outside the LOS of the user. The position of the display device, relative to the user's LOS, is automatically determined. The operational mode of the wearable device is automatically transitioned when a transition of position of the display device is detected. The wearable device may be a head-mounted display (HMD) device. A visual mode provides visual-based presentations of UIs, content, information, and data, via the display device. In contrast to a visual mode, an audible mode provides audio-based presentations of UIs, content, information, and data, via one or more audible speakers included in the wearable device.
