Abstract: A machine includes a processor and a memory connected to the processor. The memory stores instructions executed by the processor to receive a message and a message parameter indicative of a characteristic of the message, where the message includes a photograph or a video. A determination is made that the message parameter corresponds to a selected gallery, where the selected gallery includes a sequence of photographs or videos. The message is posted to the selected gallery in response to the determination. The selected gallery is supplied in response to a request.

Abstract: An electronics-enabled eyewear device includes a mode indicator comprising a series of light emitters arranged on a forward-facing surface of the eyewear device, for example being provided by a ring of LEDs arranged peripherally about a camera lens opening in a front surface of an eyewear frame. The mode indicator automatically displays different visual indications corresponding to different modes of operation or states of the eyewear device. One visual indication provides an animated pattern of circulating LEDs during video capture by the eyewear device.

Abstract: A phase change material (PCM) is positioned about a battery of an eyewear device such that a latent energy of the PCM transfers to the battery as the ambient temperature drops to maintain a battery temperature. The latent energy maintains the temperature of the battery until the PCM loses it latent energy and converts to a solid phase. At normal operating temperatures, the PCM is in the liquid phase.

Abstract: A method for prohibiting email content propagation that receives, at a server, an email message. At the server, at least one email address associated with the email message which is designated not to receive a content of the email message is identified. At the server, the email message is modified by selectively removing a content of the email message to be conveyed to the at least one email address. The server conveys the modified email message to the at least one email address. The server conveys the email message to one or more recipient email addresses except the at least one email address. Consequently, the server has sent a submitted message to multiple email addresses, while modifying the content sent to a subset of the addresses that received the email message.

A communication interface that is associated with the messaging application is generated for display, concurrently with a display of the gaming application. Functionality of the communication interface is modified based on the state in the messaging application from which the gaming application was launched.

Abstract: A wallpaper system presents a first wallpaper image of a wallpaper video to a user and receives, via a user input device, one or both of: (i) a spatial user input selection, and (ii) a time user input selection from the user to apply to the wallpaper video. In response to detecting one or both of: (i) the spatial user input selection, and (ii) the time user input selection, the wallpaper system determines one or both of: (i) a respective spatial movement parameter within a wallpaper video associated with the spatial user input selection, and (ii) a respective time coordinate within the wallpaper video associated with the time user input selection. Wallpaper system presents, via the image display, a second wallpaper image associated with one or both of: (i) the respective spatial movement parameter, and (ii) the respective time coordinate.

Abstract: A dolly zoom effect can be applied to one or more images captured via a resource-constrained device (e.g., a mobile smartphone) by manipulating the size of a target feature while the background in the one or more images changes due to physical movement of the resource-constrained device. The target feature can be detected using facial recognition or shape detection techniques. The target feature can be resized before the size is manipulated as the background changes (e.g., changes perspective).

Abstract: Electronic eyewear device providing simplified audio source separation, also referred to as voice/sound unmixing, using alignment between respective device trajectories. Multiple users of electronic eyewear devices in an environment may simultaneously generate audio signals (e.g., voices/sounds) that are difficult to distinguish from one another. The electronic eyewear device tracks the location of moving remote electronic eyewear devices of other users, or an object of the other users, such as the remote user's face, to provide audio source separation using location of the sound sources. The simplified voice unmixing uses a microphone array of the electronic eyewear device and the known location of the remote user's electronic eyewear device with respect to the user's electronic eyewear device to facilitate audio source separation.
