Systems and methods are provided for improving the latency for display of ink during user creation of ink content with an object, such as a stylus, mouse, finger (or other touch input), or other drawing device. In order to reduce or minimize the time for display of ink content created by a user, aspects of the technology described herein generate predictive wet ink that can be displayed with actual wet ink. The predictive wet ink is calculated by extending an active ink segment a predictive distance. The predictive distance is intended to be a distance between a termination ink point for an active wet ink segment and a tip of the writing object. In one aspect, the predictive distance is calculated by determining the current latency period on a touch device and the velocity of the writing object.

Devices and a method are provided for providing feedback to a user. In one implementation, the method comprises obtaining a plurality of images from an image sensor. The image sensor is configured to be positioned for movement with the user's head. The method further comprises monitoring the images, and determining whether relative motion occurs between a first portion of a scene captured in the plurality of images and other portions of the scene captured in the plurality of images. If the first portion of the scene moves less than at least one other portion of the scene, the method comprises obtaining contextual information from the first portion of the scene. The method further comprises providing the feedback to the user based on at least part of the contextual information.

A 3D (three dimensional) model reconstruction method that includes the steps outlined below. Depth data of a target object corresponding to a current time spot is received. Camera pose data of the depth camera corresponding to the current time spot is received. posed 3D point clouds corresponding to the current time spot are generated according to the depth data and the camera pose data. Posed estimated point clouds corresponding to the current time spot are generated according to the camera pose data corresponding to the current time spot and a previous 3D model corresponding to a previous time spot. A current 3D model of the target object is generated according to the posed 3D point clouds based on a difference between the posed 3D point clouds and the posed estimated point clouds.

Methods of route planning for a moveable device and associated systems are disclosed herein. In representative embodiments, the method includes (1) downsampling a 3-D point cloud generated by a distance-measurement component of the movable device to obtain a downsampled point cloud; (2) extracting ground points from the downsampled point cloud; (3) analyzing the ground points in a surface-detecting direction; and (4) identifying an object based at least in part on the downsampled point cloud and the ground points. The identified object and the ground points can be used for planning a route for the moveable device.

A method and device for real-time generation of a multiresolution representation of a digital image for real-time generation are disclosed. A sequence of main representations of the digital image is stored at successive different main resolutions in a main memory. A part of a current main representation is loaded from the main memory into a local memory via a bus. A current main representation is processed by determining a corresponding part of an intermediate representation of the image having an intermediate resolution lying between the resolution of the current main representation and the resolution of the subsequent main representation. The loading and processing steps are repeated for other parts of the current main representation until all parts of the current main representation have been successively loaded and processed.
