Abstract: In order to guide the user to a target object that is located outside of the field of view of the wearer of the AR computing device, a rotational navigation system displays on a display device an arrow or a pointer, referred to as a direction indicator. The direction indicator is generated based on the angle between the direction of the user's head and the direction of the target object, and a correction coefficient. The correction coefficient is defined such that the greater the angle between the direction of the user's head and the direction of the target object, the greater is the horizontal component of the direction indicator.

Abstract: An image copying assistant is a computing application configured to aid users in copying a digital image to a physical canvas using traditional media on the physical canvas. The image copying assistant utilizes augmented reality techniques to present features of the digital image projected onto the physical canvas. The image copying assistant detects previously generated markers in an output of a digital image sensor of a camera of a computing device and use the detected markers to calculate the plane and boundaries of the surface of the physical canvas. The image copying assistant uses the calculated plane and boundaries to determine a position of the digital image on a display of the computing device.
