A display system is provided in a vehicle and includes: an HUD positioned inside the vehicle and configured so as to display, on the vehicle window, a surrounding environment video indicating the environment surrounding the vehicle; and a display control unit controlling the HUD such that the surrounding environment video is displayed on the window in accordance with prescribed conditions associated to the vehicle or the environment surrounding the vehicle and configured so as to reduce the transmittance of the window.

A head-mounted augmented reality device (10) includes a pair of optical modules (12) for the right and left eyes of the user, each having a collimating display source (14) optically coupled to a light guide (16) for directing image illumination towards an eye of the user. A support structure (20) is supported by the head of the user. An optical bench (22) provides a first set of alignment features (26, 28, 32, 74) for aligning and affixing the right optical module and a second set of alignment features (26, 28, 32, 74) for aligning and affixing the left optical module. A suspension arrangement suspends the optical bench relative to the support structure. The optical bench (22) provides the sole mechanical connection between the pair of optical modules (12) and the support structure (20).

A wearable computing device includes: a wearable housing; a display assembly supported by the housing and switchable between (i) an active configuration to occlude an optical path between an operator field of view and an exterior of the wearable computing device, and (ii) a fail-safe configuration to clear the optical path; and a mitigation subsystem including an actuator controllable to switch the display assembly from the active configuration to the fail-safe configuration in response to detection of a display failure condition.

The head-up display device includes a display element that emits image light and a virtual image optical system. The virtual image optical system includes a lens unit and a free curved surface mirror disposed along the emission direction of the image light in this order from a position close to the display element. The display element is disposed with a tilting attitude with respect to the optical axis of the lens unit with an end on the housing aperture side in an emission surface being close to an incidence surface in the lens unit and with an end on the opposite side of the housing aperture in an emission surface being apart from an incidence surface in the lens unit. The lens unit has an optical characteristic of optically enlarging an optical path length difference according to a virtual image distance difference.

A head-mounted display comprises: a wearing body; a display; a communication module configured to perform communication connection with a mobile information terminal; a field of view (FOV) sensor configured to output status data used for determining whether the mobile information terminal is included in a user's FOV through the wearing body; and a controller connected to each of the display, the communication module, and the FOV detection sensor. The controller determines whether the mobile information terminal is included in the user's FOV based on the status data, and performs display control with respect to the display so as to display an application screen of the mobile information terminal on the display when determining that the mobile information terminal is not included in the FOV, and not to display the application screen on the display when determining that the mobile information terminal is included in the FOV.

An operating method of an electronic system is provided. The operating method of the electronic system includes generating a first user input by a first input device and performing a first input control according to the first user input during a first input operation mode, determining whether a light intersection point of a ray emitted by a second input device with a virtual reality (VR) environment exists in the VR environment, switching to a second input operation mode in response to determining that the light intersection point of the ray with the VR environment exists in the VR environment and generating a second user input by the second input device and performing a second input control according to the second user input during the second input operation mode.
