Embodiment Construction

[0020] The techniques described herein are directed to tracking a user's hand on the screen side of a handheld device using a three-dimensional (3D) sensing device to create a more natural connection between the user's hand's movement and what is happening in an augmented reality scene . In one or more implementations, the user device has multiple coordinate systems: an object-to-device coordinate system (for object space), a hand-to-device coordinate system (for control space), and a virtual cursor coordinate system (for cursor space). The user device captures the translational and rotational movements of the user's hand and / or the user device itself to control the movement of a "virtual hand" or "virtual cursor" in three dimensions (3D). The virtual cursor can then interact with an augmented reality (AR) scene. Since the user's hand can have twenty-seven degrees of freedom, more mapping coordinate options between coordinate systems can be provided to control the movement o...

Abstract

A method for spatial interaction in augmented reality (AR) includes displaying an AR scene including an image of a real world scene, a virtual target object, and a virtual cursor. The position of the virtual cursor is provided according to a first coordinate system in the AR scene. The user device tracks the gesture of the user device relative to the user's hand according to the second coordinate system. The second coordinate system is mapped to the first coordinate system to control movement of the virtual cursor. In the first mapping mode, the movement of the virtual cursor is controlled to change the distance between the virtual cursor and the virtual target object. In a second mapping mode, virtual cursor movement is controlled to manipulate the virtual target object. User input is detected to control which of the first mapping mode or the second mapping mode is used.

Description

[0001] Cross References to Related Applications [0002] This patent application claims the benefit of U.S. Provisional Application No. 62 / 080,050, entitled "SPATIAL INTERACTION INAUGMENTED REALITY," filed on November 14, 2014, assigned to the present assignee, and is expressly incorporated herein by reference in its entirety. technical field [0003] Aspects of the invention relate generally to augmented reality, and in particular, to spatial interaction in an augmented reality environment. Background technique [0004] Augmented reality is an emerging technology that combines images of the real world with computer-generated data, such as graphical or textual information. Augmented reality technology superimposes graphics, audio, and other sensory enhancements onto the real world using advanced user devices (eg, tablet computers, smartphones, etc.), thus augmenting reality. Augmented reality allows users to interact with real objects in real time, thereby aligning virtua...
