Abstract: Disclosed is a method, implemented in a visualization device, to assist a user in placing 3D objects. In certain embodiments the method includes displaying, on a display area of the visualization device, to a user, various virtual 3D objects overlaid on a real-world view of a 3D physical space. The method can further include a holding function, in which a first object, of the various virtual 3D objects, is displayed on the display area so that it appears to move through the 3D physical space in response to input from the user, which may be merely a change in the user's gaze direction. A second object is then identified as a target object for a snap function, based on the detected gaze of the user, the snap function being an operation that causes the first object to move to a location on a surface of the target object.

Abstract: Methods for providing real-time feedback to an end user of a mobile device as they are interacting with or manipulating one or more virtual objects within an augmented reality environment are described. The real-time feedback may comprise visual feedback, audio feedback, and/or haptic feedback. In some embodiments, a mobile device, such as a head-mounted display device (HMD), may determine an object classification associated with a virtual object within an augmented reality environment, detect an object manipulation gesture performed by an end user of the mobile device, detect an interaction with the virtual object based on the object manipulation gesture, determine a magnitude of a virtual force associated with the interaction, and provide real-time feedback to the end user of the mobile device based on the interaction, the magnitude of the virtual force applied to the virtual object, and the object classification associated with the virtual object.

Abstract: Disclosed are a technique of generating and displaying a virtual measurement tool in a wearable visualization device, such as a headset, glasses or goggles equipped to provide an augmented reality and/or virtual reality experience for the user. In certain embodiments, the device generates the tool by determining multiple points, each at a different location in a three-dimensional space occupied by the user, based on input from the user, for example, by use of gesture recognition, gaze tracking and/or speech recognition. The device displays the tool so that the tool appears to the user to be overlaid on a real-time, real view of the user's environment.
