Methods and apparatus include providing a head-mounted display to be worn by the user and presenting a video to the user through the head-mounted display; measuring outside world information; detecting whether or not the outside world information contains any notification information to be notified to the user, including detection of at least one reference position, which is set by the user as notification information; and notifying the user when notification information is detected.

A wearable heads-up display includes a power source, laser sources, and a lightguide. A photodetector is positioned to detect an intensity of a test light emitted at a perimeter of the lightguide from an optical path within the lightguide. A laser safety circuit provides a control to reduce or shut off a supply of electrical power from the power source to the laser sources in response to an output signal from the photodetector indicating that the detected intensity is below a threshold.

Systems and methods for augmented-reality-based marine navigation. An electronic controller plots a navigational route between a current geospatial position of a host vessel and a target destination of the host vessel. The navigational route is plotted as a series of waypoints. The electronic controller receives an electronic transmission from at least one nearby ship indicative of a current position of the at least one nearby ship (e.g, an MS transmission) and updates the navigational route based at least in part on the received electronic transmission. A graphical representation of the updated navigational route and a graphical indication of the current position of the at least one nearby ship (e.g., a conformal overlay of the at least one nearby ship) are then displayed on a head-worn augmented reality display device.

Methods and apparatus providing a head-mounted display to be worn by the user and presenting a video to the user through the head-mounted display; measuring outside world information via an outside world measurement section of the head mounted display; detecting, via a notification information detection section, whether or not the information measured by the outside world measurement section contains any notification information to be notified to the user, including that the notification information detection section detects at least one reference position, which is set by the user as notification information; and notifying the user, via a notification section, when the notification information detection section detects notification information by way of displaying a video of the at least one reference position to the user in the head-mounted display.

A display control device configured to control a projection device that projects an image on a windshield of a vehicle includes a circuitry. The circuitry is configured to determine a target ground object that is a ground object other than an object which a driver of the vehicle is to be warned of, the target ground object being used to provide the driver with a sense of distance to the object, and project, using the projection device, an image for indicating a presence of the object in a manner that allows the driver to perceive a sense of distance to the object on a windshield of the vehicle, such that a first part of the image and the target ground object overlap each other and a second part of the image and the target ground object do not overlap each other when viewed from the driver.

A head mounted display (HMD) device that includes a plurality of sensors, an actuator, a plurality of protective mechanisms, and a processor configured to identify a situational state of a user of the HMD device within a proximity of the user, based on sensor input received from the plurality of sensors. A risk-level of a potential injury to the user from a component of the HMD device is determined based on the identified situational state and the sensor input. A protective mechanism is selected from the plurality of protective mechanisms based on the identified situational state and the determined risk-level. The actuator is controlled to deploy the selected protective mechanism to mitigate injury to the user from the component of the HMD device, based on the identified situational state and the determined risk-level.

Innovative techniques and apparatuses to control metaverse presentation are disclosed. The proposed techniques and apparatuses allow prevention of overindulgence to metaverse presentation based on user biometrics (e.g., oxygen saturation, heart rate, body temperature, blood pressure, etc.). If the biometrics indicate that the user's health is compromised due to the metaverse presentation, the metaverse presentation (visual, audio, haptic outputs) may be altered to reduce the user's overindulgence.

A head-mounted display, a display control method, and a program that facilitate a user to understand proximity between the user and an object around the user are provided. A display block (36) is arranged in front of the eyes of the user wearing a HMD (12). In accordance with proximity between the user and an object around the user, the HMD (12) controls the display block (36) so as to have the user visually recognize a forward direction of the display block (36).

A movable carrier auxiliary system includes a state detecting device, a braking device, an environmental detecting device and an emergency brake controlling device. The state detecting device detects a movement state of a movable carrier. The environmental detecting device includes at least one image capturing module and an operation module. The brake controlling method thereof includes receive the movement state detected by the state detecting device, and deriving an operating distance based on the movement state with the operation module; capture the environmental image with the image capturing module; determine whether there is an obstruction within the operating distance based on the environmental image; automatically actuate the braking device with the emergency brake controlling device when there is the obstruction within the operating distance in the environmental image, thereby to stop the movable carrier within the operating distance.

The invention concerns an augmented vision system (1) comprising: a displaying device (3) comprising: a fixing element (31) for coupling the displaying device (3) to a head-mountable component (90) configured to be positioned in front of a 5 face (102) of a user (100), and a display body (32) being coupled to said fixing element (31) by means of a pivoting link (321, 322, 323) providing a rotation of the display body with respect to the fixing element around a rotational axis (38); the display body (32) comprising 10 a display (33) configured to display thermal data and/or images provided by a thermal sensing device (2); and a first surface portion (325) configured to enter in contact with a forehead of a user, when said head-mountable component (90) is positioned in front of the face of the user, so as to rotate the display 15 body (32) to a predefined angular positioning (381) around the rotational axis (38).
