A wearable head-up display which allows for convenient and safe stowage when not in use. A hinge component is positioned within the optical path from an image projector to a display component which ensures optical alignment for projection. A detection means is provided to signal when the wearable device is in a folded position in order to deactivate the projector.

A safety system having at least one safety module, which is associated with a system controlled by a controller. A portable augmented reality unit is provided. The augmented reality unit has a camera and a projection unit. The safety module has a connection module. The connection module is designed to provide a data connection with the augmented reality unit, and further, a data connection with the controller. By means of the augmented reality unit, a code identifying the system is captured and transmitted to the connection module. Depending on the code captured by the augmented reality unit, parameters of operating elements are supplied. Based on the parameters, the operating elements are made visible by means of the projection unit of the augmented reality unit.

An information processing apparatus according to an embodiment of the present technology includes a setting unit and a display control unit. The setting unit sets a limitation region in which entry is limited. The display control unit controls display of a blocking object that is a virtual object that blocks entry into the limitation region on the basis of a display area in which the virtual object is capable of being displayed. With this configuration, the blocking object can be appropriately displayed, and natural virtual experience can be provided.

A projection display device includes: a light modulation unit that spatially modulates, in accordance with image data that is input, light emitted by a light source; a housing that accommodates the light modulation unit; a projection optical system that is accommodated in the housing and projects the light that has been spatially modulated onto a projection surface of a vehicle through an opening portion of the housing; and a cover that closes the opening portion, the cover has a shape whose longitudinal direction is a direction extending from a driver's seat of the vehicle toward a passenger seat of the vehicle, and a front surface of the cover is closer to the projection surface than a reference plane and has a shape as defined herein.

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 virtual image display device includes a virtual image position selector, a vision measurement interface, a display information acquirer, a display image generator, and a projection processor. The virtual image position selector selects either a first virtual image position or a second virtual image position as a display position of the virtual image. The vision measurement interface measures a vision of a user based on a user's response to a vision measurement image projected as a virtual image at the display position. The display information acquirer acquires information to be shown. The display image generator generates a display image showing an image corresponding to the information acquired by the display information acquirer in a size determined by the vision acquired by the vision measurement interface. The projection processor performs a projection process of projecting the display image generated by the display image generator as a virtual image.

An HMD device is configured to vertically adjust the ground plane of a rendered virtual reality environment that has varying elevations to match the flat real world floor so that the device user can move around to navigate and explore the environment and always be properly located on the virtual ground and not be above it or underneath it. Rather than continuously adjust the virtual reality ground plane, which can introduce cognitive dissonance discomfort to the user, when the user is not engaged in some form of locomotion (e.g., walking), the HMD device establishes a threshold radius around the user within which virtual ground plane adjustment is not performed. The user can make movements within the threshold radius without the HMD device shifting the virtual terrain. When the user moves past the threshold radius, the device will perform an adjustment as needed to match the ground plane of the virtual reality environment to the real world floor.

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.

An integrated computational interface device may include a portable housing having a key region and a non-key region; a keyboard associated with the key region of the housing; and a holder associated with the non-key region of the housing. The holder may be configured for selective engagement with and disengagement from the wearable extended reality appliance, such that when the wearable extended reality appliance is selectively engaged with the housing via the holder, the wearable extended reality appliance is transportable with the housing.
