Abstract: Techniques are disclosed for assigning an attribute to an image asset. A touch-sensitive device can display images one at a time. Each image has a status attribute that indicates whether the image has been picked or rejected. The user can display and change the status of the displayed image using a vertical touch contact gesture. An upward gesture may be used to assign a picked status to an image asset or remove a rejected status from the image asset. A downward gesture may be used to assign a rejected status to the image asset or remove a picked status from the image asset. A user interface affordance is configured to display a flag graphic and text string corresponding to the current status of the image being displayed and an animated graphic in response to a vertical touch contact gesture for changing the status of the image asset.

Abstract: Systems and methods for computer-assisted drawing are disclosed. For example, one disclosed method includes the steps of determining a perspective based on at least one perspective point; receiving a sketch drawing input and generating a sketch line segment based on the drawing input; determining a conformance of the sketch line segment to the perspective; and responsive to determining the conformance exceeds a threshold: adjusting the sketch line segment based on the conformance, and displaying the adjusted sketch line segment.

Abstract: Methods for differentiating touch inputs are disclosed. A method detects a touch input by receiving contact at a computing device's touch surface and identifies whether the touch input was received from a stylus based on additional input received from the stylus. The method responds to the touch input, wherein the response differs based on whether the touch input was received from the stylus. The detecting, identifying and responding are performed at the computing device. A stylus has a capacitive tip, a wireless transceiver, and a pressure sensor for determining a pressure level received at the tip. The stylus determines if a pressure level measured by the pressure sensor has reached a threshold, suppresses capacitive output from the tip to a touch surface if it is determined that the threshold has not been reached, and communicates a message to the computing device based on determining that the threshold has been reached.
