Various AR systems include a fail-safe mode where the user can see the region in front of the user without the display and/or outward facing imaging sensor (e.g., camera), if for example, power to the display and/or outward facing imaging sensor (e.g., camera) is lost or the outward facing imaging sensor (e.g., camera) and/or display malfunction.

A system and method for operating a keyboard and wearable extended reality appliance combination to control a virtual display are disclosed. The system may include a processor configured to receive, from a first hand-position sensor associated with the wearable extended reality appliance, first signals representing first hand-movements; receive, from a second hand-position sensor associated with the keyboard, second signals representing second hand-movements, wherein the second hand-movements include actions other than interactions with a feedback component; and control the virtual display based on the first signals and the second signals.

Systems, methods, and non-transitory computer readable media for coordinating virtual content display with mobility status are disclosed. A non-transitory computer readable medium contains instructions that cause a processor to: access rules associating user mobility statuses with display modes; receive first sensor data reflecting a mobility status of a user during a first time period; based on the first sensor data, determine that during the first time period the user is associated with a first mobility status; implement a first accessed rule to generate a first display of virtual content; receive second sensor data reflecting the mobility status of the user during a second time period; based on the second sensor data, determine that during the second time period the user is associated with a second mobility status; and implement a second accessed rule to generate a second display of the virtual content different from the first display.

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.

A system includes a personal protective equipment (PPE) configured to be worn by an agent. The PPE includes a sensor assembly comprising a radar device configured to generate radar data, a microphone configured to capture speech input from the agent, and an inertial measurement device configured to generate inertial data. The system includes a computing device configured to: process sensor data from the sensor assembly, the sensor data including at least the radar data and the inertial data, to generate pose data of the agent based on the processed sensor data, the pose data including a location and an orientation of the agent as a function of time, to process the speech input to identify an item of interest in an environment in which the PPE is deployed, and to form mapping information for the environment with the item of interest being marked, based on the processed speech input.

A head-up display (HUD) apparatus comprises a housing including a lower case that is open at a top thereof and defines an internal space, and an upper case that corresponds to the lower case to cover the top of the lower case; an aspherical mirror configured to reflect an image emitted from a picture generation unit onto a windshield, and the aspherical mirror being disposed in the lower case; and a crumple zone including an impact absorbing unit configured to be disposed in the housing and to absorb an impact transmitted to the housing, in the event of a vehicle collision.
