Systems, devices, media, and methods are presented for composing and sharing a message based on the motion of a handheld electronic device such as a ring. The methods in some implementations include presenting a keyboard on a display, collecting course data associated with a course traveled by the ring, and overlying a trace onto the keyboard, such that the trace is correlated in near real-time with the course traveled by the ring. In some implementations the display element is part of a portable device, such as the lens of an electronic eyewear device. Based on the course data relative to the key locations on the keyboard, the system identifies and presents candidate words to be included in a message.

Techniques for determining when to store content and when to refrain from storing content are described herein. In some instances, devices exchange communications that include different types of content, such as text, audio data, video data, image data, or the like. For instance, a first device may receive, from a second device, a communication that includes audio data representing speech of a user of the second device, along with text for display on the first device. The text may comprise a transcription of the audio file, additional commentary provided by the user of the second device, or the like. Upon receiving the communication that includes text and audio data, the first device may determine whether or not to store the audio data. For instance, the first device may determine whether it currently stores this audio content. If so, then the first device may refrain from storing the content again.

A method may include presenting a user interface on a display device of a computing device, the user interface including: a search query input element; a plurality of graph type options; a graph level selection element; and a graph presentation area; receiving a search query inputted into the search query input element, the search query identifying a concept object in an ontology; retrieving data associated with the concept object from a graph database based on selections made in the graph type options and the graph level selection element, the data including a set of result objects related to the concept object; and rendering a hierarchical graph in the graph presentation area, the hierarchical graph illustrating the set of result objects and the concept object as interactive nodes.

Improvements to existing technologies associated with point-of-sale transactions and merchant ecosystems to, among other things, reduce in-person contact and, in some examples, improve the efficiency at which point-of-sale transactions are completed (i.e., reduce friction) are described. In some examples, such reduced in-person contact and/or improved efficiencies can limit transmission of infectious diseases. As such, techniques described are directed to modifying aspects of point-of-sale transactions such that they occur on different computing devices (e.g., customer computing devices instead of merchant computing devices), are automated, and/or occur at different times than with conventional point-of-sale transactions. Furthermore, in at least one example, techniques described can leverage a distributed, network-based merchant ecosystem—comprising multiple merchant computing devices and/or customer computing devices that are specially configured to communicate with a service provider—to facilitate social distancing, which can reduce in-person contact and, in some examples, improve the efficiency at which point-of-sale transactions are completed.

A computer apparatus and methods generate multi-parametric color composite images from multi-echo chemical shift encoded (CSE) MRI. Some embodiments use inherently co-registered images (i.e., image maps) that are combined into a single intuitive composite color image. The color (e.g., brightness, hue, and/or saturation) reflects in part the water and fat content, and other properties, particularly T2* relaxation (related to magnetic susceptibility) of the tissue.

A computing device is coupled to a display device, and includes a data monitoring software application program executing on a processor within a data monitoring system. Via the data monitoring software application program, various techniques are performed for generating user interfaces for data monitoring and event response. In a first technique, the data monitoring software application program displays a user interface that includes a first region including a data visualization and a second region including one or more images of a video stream. In a second technique, the data monitoring software application program generates a user interface associated with an event, receive an input corresponding to interaction with a user interface element in the user interface, and initiates an event channel associated with the event in response to the input.

Systems and methods are provided for improved security services. In one aspect, a method is provided for controlling an autonomous data machine situated near a monitored environment. The method comprises: obtaining security data from a plurality of data sources; analyzing the security data to generate an analysis result; determining, based on the analysis result, an action to be performed by the autonomous data machine; and transmitting a command to the autonomous data machine causing it to perform the action.

Listeners to media programs provide feedback to creators or other entities associated with the media programs in the form of one or more spoken utterances. When a listener to a media program speaks one or more words to a microphone or other system, the words are captured and processed to determine an emotion of the listener, or to determine whether the words include any objectionable content. Data including the spoken words is captured and stored, and presented to the creator of the media program. Notifications of the utterances are provided to the creator, who may identify one of the utterances, and include the utterance in the media program, or invite the listener who provided the utterances to participate in the media program.
