Abstract: Images of a scene are received. The images represent viewpoints corresponding to the scene. A pixel map of the scene is computed based on the plurality of images. Multi-plane image (MPI) layers from the pixel map are extracted in real-time. The MPI layers are aggregated. The scene is rendered from a novel viewpoint based on the aggregated MPI layers.

Abstract: A client device processing received emoji messages using emoji-first messaging. Text messaging is automatically converted to emojis by an emoji-first application so that only emojis are communicated from one client device to another client device. Each client device has a library of emojis that are mapped to words, which libraries are customizable and unique to the users of the client devices, such that the users can communicate secretly in code. Upon receipt of a string of emojis, a user can select the emoji string to convert to text if desired, for a predetermined period of time.

Abstract: Shortcut keypad system for electronic communications comprises first apparatus and second apparatus. First apparatus and second apparatus each comprise an input device, a processor and a memory. The input device comprises selectable items including first selectable item. The processor of the first apparatus receives a selection of the first selectable item, and transmits a signal corresponding to the first selectable item to the second apparatus. The processor of the second apparatus receives the signal corresponding to the first selectable item, and causes the input device of the second apparatus to indicate that the signal corresponding to the first selectable item is received. Other embodiments are described herein.

Abstract: An augmented reality system having a light source and a camera. The light source projects a pattern of light onto a scene, the pattern being periodic. The camera captures an image of the scene including the projected pattern. A projector pixel of the projected pattern corresponding to an image pixel of the captured image is determined. A disparity of each correspondence is determined, the disparity being an amount that corresponding pixels are displaced between the projected pattern and the captured image. A three-dimensional computer model of the scene is generated based on the disparity. A virtual object in the scene is rendered based on the three-dimensional computer model.

Abstract: An apparatus with a selector input device to transmit an audio signal comprises a microphone, a communication interface, and a selector input device. The apparatus can also comprise a processor and a memory having instructions stored thereon, when executed by the processor, causes the processor to perform operations comprising detecting an activation of the selector input device. In response to detecting the activation, the processor captures the audio signal via the microphone and transmits the audio signal via the communication interface to a first client device. Other embodiments are described herein.

Abstract: An audio response system can generate multimodal messages that can be dynamically updated on viewer's client device based on a type of audio response detected. The audio responses can include keywords or continuum-based signal (e.g., levels of wind noise). A machine learning scheme can be trained to output classification data from the audio response data for content selection and dynamic display updates.

Abstract: Method of performing acoustic zooming starts with microphones capturing acoustic signals associated with video content. Beamformers generate beamformer signals using the acoustic signals. Beamformer signals correspond respectively to tiles of video content. Each of the beamformers is respectively directed to a center of each of the tiles. Target enhanced signal is generated using beamformer signals. Target enhanced signal is associated with a zoom area of video content. Target enhanced signal is generated by identifying the tiles respectively having at least portions that are included in the zoom area, selecting beamformer signals corresponding to identified tiles, and combining selected beamformer signals to generate target enhanced signal. Combining selected beamformer signals may include determining proportions for each of the identified tiles in relation to the zoom area and combining selected beamformer signals based on the proportions to generate the target enhanced signal. Other embodiments are described herein.

Abstract: Method of detecting objects in non-perspective images starts by generating an arrangement of tiles based on a field of view of a non-perspective camera lens, a predetermined size of the tiles, and a predetermined maximum object radius.
The arrangement of the tiles includes the minimum number of tiles to cover the field of view. A non-perspective image is then captured using the non-perspective camera lens. The non-perspective image may be a still image frame or a video. Using the tiles, a plurality of images are generated, respectively, and at least a portion of a first object is detected in one or more images. The first object is generated using the one or more images that include the at least the portion of the first object, and the first object is displayed on a display interface. Other embodiments are described herein.-

Abstract: Systems and methods are provided that relate to vibrational input elements configured to provide inputs to control an application executed by a mobile computing device. The vibrational input elements may produce distinct vibration patterns that are detectable by a sensor of the mobile computing device. The respective vibration patterns may correspond to one or more actions that may be performed in relation to the application.

Abstract: Method to retrieve media content items using captured parameters associated with a moment starts with a processor detecting an activation of a selectable element. Processor determines parameters associated with the activation including a date and a time that the activation is detected and a location of the selectable element when the activation is detected. Processor stores in a memory of a client device a first record including the parameters. When a request for the first record is received, processor transmits the request to a server for media content items associated with at least one of the parameters of the first record. Media content items are uploaded to the server from client devices communicatively coupled to the server. Processor causes a display of the client device to display the media content items. Other embodiments are described herein.
