Abstract: A method includes a computing system receiving an image of a real-world environment, the image including at least a portion of a hand of a user of an artificial reality device, the hand comprising a palm and a plurality of fingers. The computing system determines a hand pose of the hand using the image, and defines, based on the hand pose, a three-dimensional surface positioned in the palm of the hand. The computing system determines, based on the hand pose, distances between predetermined portions of the plurality of fingers and the three-dimensional surface. The computing system assigns, based on the distances, a pose value for each of the plurality of fingers of the hand and determines, based on the pose values for the plurality of fingers, a grab state of the hand.

Abstract: In general, the subject matter described in this specification can be embodied in methods systems, and program products for determining a change in a mode of transportation. A change in a mode of transportation of the mobile computing device may be determined by determining that a speed of the mobile computing device has changed. A first geographical location is stored as a geographical location of the mobile computing device that corresponds to the change in mode of transportation. A graphical indication of the first geographical location is displayed. The graphical indication of the first geographical location is different than graphical indications for one or more other geographical locations of the mobile computing device at one or more other times. The one or more other geographical locations were not determined to correspond to a change in mode of transportation.

Abstract: The present disclosure is directed to a system and method for dynamically updating list views. In some implementations, a method for expanding items includes presenting media display including a list of a plurality of items. The presented list includes an expanded view of a first item from the plurality of items at a predefined position in the media content. A request to scroll to a second item from the plurality of items is received. A view of the second item is automatically expanding in response to at least the request. The expanded view of the second item is presented at the predefined position in the media display.

Abstract: Some techniques feature a computer-implemented method for messages associated with a user location. The method involves determining, by a mobile computing device, an estimated geographic location of the mobile computing device. The method includes receiving, at the mobile computing device, one or more messages associated with an area within the estimated geographic location, where the one or more messages include messages posted by users of a system that associates messages that those users posted about the area within the estimated geographic location. The method involves providing, on a display of the mobile computing device, one or more posted message icons that are presented in a layer over a map, where the one or more posted message icons represent the one or more posted messages. In a system, the one or more posted messages may not appear on mobile devices after a predetermined amount of time from their respective postings.
