Abstract: Systems and methods are described to enable the creation and use of one or more interest meshes that may comprise interest values associated with points of interest in a virtual environment. The virtual environment may use a mesh to guide a user toward points of interest. Guiding may comprise haptic, visual, and/or audio cues and may also comprise moving the virtual environment around the user. Further, events may be triggered in the virtual environment that may change one or more meshes and/or create a new point of interest for a user.

Abstract: Future data connection quality may be predicted based on historical data connection quality, and future requests for data may be predicted based on past requests. These predictions may be used to help decide whether, when, and/or how to deliver the data in a proactive manner. For example, according to some aspects described herein, a future data connection quality may be predicted based at least on historical data connection quality. It may be determined whether to pre-deliver at least a portion of an item of content based at least on the predicted future data connection quality. The pre-delivered portion may include any portion of the content including a latter portion of the content. If so, then the at least the portion of the item of content may be pre-delivered to the device and/or to another destination.

Abstract: A method implements data visualization collaboration. The method displays, for a second user, an interface with a comment pane that displays a first comment text and a first thumbnail image of a data visualization generated according to a first visual specification, from a first user. In response to detecting an input from the second user to select the first thumbnail image, the method generates and displays the data visualization. The method receives, from the second user, input modifying the data visualization, and input specifying a second comment that refers to the data visualization. In response, the method generates a second thumbnail image and a second visual specification corresponding to the modified data visualization, and transmits that information along with the second comment text to the first user.

Abstract: A method of distinguishing between a first-type touch event and a second-type touch event is disclosed. A force-measuring and touch-sensing system includes piezoelectric force-measuring elements (PFEs) and piezoelectric ultrasonic transducers (PUTs), wherein each PUT can be configured as a transmitter (PUT transmitter) and/or a receiver (PUT receiver). The force-measuring and touch-sensing system is configured at a sense region.

Voltage signals are generated at PFEs in response to a low-frequency mechanical deformation of the respective piezoelectric capacitors. An event is determined to be a first-type touch event or a second-type touch event depending on a PUT data decrease and a magnitude of PFE data.
