Methods, systems, apparatuses, and computer-readable media are provided for enabling collaboration between writers. In one implementation, the computer-readable medium includes instructions to cause a processor to receive, from an image sensor associated with a wearable extended reality appliance, image data representing a physical surface, the physical surface being a compilation of pages; receive, from a computing device associated with a virtual writer, annotation data representing first virtual markings associated with a first page of the compilation and second virtual markings associated with a second page of the compilation; analyze the image data to determine that the compilation is opened to the first page; and cause the wearable extended reality appliance to overlay the first virtual markings on the first page of the compilation and exclude overlaying the second virtual markings on the first page of the compilation.

A life-assisting system to enhance the quality of life for people with visual impairment. The system integrates state-of-the-art sensing and sensory stimulation with light detection and ranging (LiDAR), machine learning, and advanced haptic navigation to provide the visually impaired population with a real-time haptic map of the three-dimensional environment and auditory descriptions of objects within that environment. By allowing the visually impaired population to sense objects in the surrounding environment through haptic and auditory feedback, the disclosed system has the potential to promote individual independence, reduce anxiety and stress, facilitate access to educational and employment opportunities, and reduce social and economic gaps. To provide those benefits, the system uses multi-modal learning to convert higher dimensional (e.g., four-dimensional) scene data into lower dimensional (e.g., one-dimensional) auditory data and (e.g., two- or three-dimensional) haptic data.

Systems, methods, and non-transitory computer readable media including instructions for extracting content from a virtual display are disclosed. Extracting content from a virtual display includes generating a virtual display via a wearable extended reality appliance, wherein the virtual display presents a group of virtual objects and is located at a first virtual distance from the wearable extended reality appliance; generating an extended reality environment via the wearable extended reality appliance including at least one additional virtual object at a second virtual distance from the wearable extended reality appliance; receiving input for causing a specific virtual object to move from the virtual display to the extended reality environment; and in response, generating a presentation of a version of the specific virtual object in the extended reality environment at a third virtual distance different from the first virtual distance and the second virtual distance.

A system assesses activity and displays a unitless activity value. A detector senses activity of a user. A processor reads sensed activity data from the detector. A display displays the unitless activity value. An enclosure houses the detector and the processor. The processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.

Leak detection user interfaces are provided. In general, a user interface for a pipeline management system can be configured to provide information regarding one or more pipelines to a user. The information can include data gathered using one or more sensors sensing various parameters. The information on the user interface can include results of analysis of the gathered data, such as notifications that the gathered data indicates an anomaly with a pipeline. The notifications of anomalies can be provided on the user interface in real time with the data analysis. Accordingly, the user can trigger one or more corrective actions such as notifying maintenance personnel local to a location of the identified anomaly, remotely controlling the pipeline with the anomaly to close valve(s) and/or other equipment to prevent fluid flow in the pipeline in the area of the detected anomaly, etc.

The present disclosure describes a system and method designed to protect the contents of a region or space within a facility (e.g., building, home, vehicle, outdoor space, etc.). The system is configured to identify an area to be protected (e.g., nightstand, medicine cabinet, safe), monitor surroundings, and manage and deploy response(s) to threats to the region or space under protection. The system may also be configured to provide incremental warnings, interventions, or countermeasures to deter people or animals from accessing the Protected Space.
