Abstract: A computing device obtains an image depicting a watch and performs segmentation on the watch in the image to generate a segmented watch region comprising a watch case region, a first watch strap region, and a second watch strap region. The computing device generates a three-dimensional (3D) mesh according to the watch case region, the first watch strap region, the second watch strap region, and a pre-defined skeleton containing at least one straight part and at least two curved parts. The computing device generates texture attributes according to the segmented watch and applies the texture attributes to the 3D mesh to generate a textured 3D watch object. The computing device renders the textured 3D watch object in an augmented reality display.

Abstract: The present invention provides improved driving methods for four particle electrophoretic displays that improves the performance of such displays when they are deployed in low temperature environments and the displays are required to be updated when positioned vertically (i.e., the driving electric fields are substantially perpendicular to the direction of Earth's gravity). Methods are provided for displaying each of the colors at each pixel, as desired, with minimal interference (contamination) from the other particles.

Abstract: The present invention provides four-particle electrophoretic displays with improved driving methods to achieve better color separation between adjacent pixel electrodes. The driving methods improve the color state performance when a first pixel is displaying a mixed state of a first highly-charged particle and a second lower-charged particle of the opposite polarity, while a neighboring pixel is displaying a state of a second highly-charged particle having the opposite polarity to the first highly-charged particle. The particles can be, for example, all reflective or one type of particle can be partially light transmissive.

The computing device renders an augmented reality object on the hand depicted in the image according to the adjusted zoom scale and the pose of the hand depicted in the image.

Abstract: A computing device prompts a user to place the user’s hand including a wrist next to a facial region of the user. The computing device obtains an image depicting the facial region and a wrist of the user. The computing device measures a diameter of an iris in the facial region depicted in the image and measures a width of a wrist of the hand depicted in the image. The computing device estimates an actual wrist width of the user’s hand based on an actual iris diameter, the measured diameter of the iris in the facial region depicted in the image, and the measured width of the wrist of the hand depicted in the image.
