Abstract: A smart glass including photoplethysmography and electrocardiogram sensors to determine a health condition of the user is provided. The smart glass includes a frame for holding two eyepieces, the frame having two nose pads to rest on a user's nose, and two arms to rest on two user's ears, a sensor mounted on at least one of the nose pads or the arms, and configured to collect an optical signal from a user's blood vessel, and a processor configured to obtain a waveform from the optical signal or the electrical signal, and to determine a cardiovascular parameter based on the waveform.

Abstract: The disclosed camera system may include a primary camera and a plurality of secondary cameras that each have a maximum horizontal FOV that is less than a maximum horizontal FOV of the primary camera. Two of the plurality of secondary cameras may be positioned such that their maximum horizontal FOVs overlap in an overlapped horizontal FOV and the overlapped horizontal FOV may be at least as large as a minimum horizontal FOV of the primary camera. The camera system may also include an image controller that simultaneously activates two or more of the primary camera and the plurality of secondary cameras when capturing images from a portion of an environment included within the overlapped horizontal FOV. Various other systems, devices, assemblies, and methods are also disclosed.

Abstract: In one embodiment, a method includes retrieving a media content item for display on a projectable surface. The method includes sending, to an interaction device including a projector and a camera, instructions causing the camera to capture one or more images of the projectable surface, receiving the one or more images from the interaction device, and determining one or more attributes of the surface based on the one or more images. The method also includes modifying the media content item based at least in part on the one or more attributes of the projectable surface and sending, to the interaction device, the modified media content item and instructions causing the projector to project the modified media content on the projectable surface.

Abstract: In one embodiment, a method includes sending, to an interaction device including a projector and a camera, a media content item and instructions causing the projector to project the media content item on a projectable surface and receiving, from the interaction device, one or more media objects captured by the camera, where one or more of the media objects include images of a user in proximity to the projectable surface. The method includes determining one or more movements of the user based on the one or more of the media objects and updating the media content item based on the determined movements. The method also includes sending, to the interaction device, the updated media content item and instructions causing the projector to project the updated media content item on the projectable surface.

Abstract: A method includes retrieving a media content item for display to a user in an environment. The method includes receiving, from one or more interaction devices each including a projector and a camera, one or more media objects captured by one or more cameras, where one or more of the media objects include images of the user, and determining a location of the user in the environment based on an analysis of the one or more of the media objects. The method also includes identifying one of the interaction devices based on the determined location of the user and sending, to the identified interaction device, the media content item and instructions causing the projector associated with the identified interaction device to project the media content item.

Abstract: A method includes sending, to an interaction device including a projector and a camera, instructions causing the projector to project a light pattern to each of one or more specified directions and receiving, from the interaction device, one or more images each including illumination patterns associated with one or more surfaces of a specified direction. The method also includes constructing, based on the projected light patterns and the received illumination patterns, a model describing an environment of the interaction device, where the model includes one or more characteristics of each of one or more objects in the environment and one or more characteristics of each of one or more surfaces in the environment.

Abstract: Systems, methods, and non-transitory computer-readable media can determine at least one media content item that was captured and provided by a camera device; determine at least one story associated with the camera device, the story publishable through a social networking system; and publish the at least one media content item in the story publishable through the social networking system.

Abstract: Systems, methods, and non-transitory computer-readable media can determine that one or more viewers of a live content stream selected at least one option for interacting with a broadcaster of the live content stream; determine audio-based feedback corresponding to the selected option; and provide the audio-based feedback to be outputted to the broadcaster through an audio device.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a first faceplate installed in the computing device, the first faceplate being an attachment that is capable of being physically installed in the computing device. A faceplate profile associated with the first faceplate can be determined. At least one setting of the computing device or operation performed by the computing device can be modified based at least in part on information specified by the faceplate profile associated with the first faceplate.

Abstract: Systems, methods, and non-transitory computer-readable media can determine content captured and provided by a first wearable device associated with a first user of a social networking system; determine a second wearable device linked to the first wearable device; and provide the captured content to a computing device of a second user associated with the second wearable device, the captured content being provided through the social networking system.

Abstract: Systems, methods, and non-transitory computer-readable media can determine at least one media content item that was captured and provided by a camera device; determine at least one story associated with the camera device, the story publishable through a social networking system; and publish the at least one media content item in the story publishable through the social networking system.

Abstract: Systems, methods, and non-transitory computer-readable media can determine content that was captured and provided by a camera device. At least one event that occurred in a social networking system in response to the content can be determined. One or more instructions can be provided to the camera device for illuminating one or more light sources associated with the camera device. The one or more light sources can be illuminated based at least in part on a pre-defined illumination pattern that visually communicates occurrence of the event.
