Abstract

In an augmented reality and/or a virtual reality system, virtual annotation surfaces, or virtual sheets, or virtual whiteboards, may be materialized in in response to a detected gesture. A user may annotate, adjust, store, review and revise the virtual annotation surfaces, and allow for collaboration with other users, while in the current virtual environment, and/or within another virtual environment, and/or outside of the virtual environment.

Background

An augmented reality (AR) and/or virtual reality (VR) system may generate an immersive, three-dimensional (3D) virtual environment. A user may interact with objects in this virtual environment using various electronic devices, such as, for example, a helmet or other head mounted device including a display, glasses or goggles that a user looks through when viewing a display device, one or more handheld electronic devices such as controllers, joysticks and the like, gloves fitted with sensors, keyboards, mouse, and other electronic devices.

Summary

In one aspect, a method may include displaying, on a display of a head mounted display (HMD) device, a virtual environment, detecting, outside of the HMD, a gesture input, generating, in response to detection of the gesture input, a virtual notation surface, and displaying the virtual notation surface as a virtual object in the virtual environment, detecting, outside of the HMD, another gesture input and annotating the virtual notation surface based on the detected gesture input, and displaying the annotated virtual notation surface as a virtual object in the virtual environment.

In another aspect, a computing device configured to generate a virtual reality environment may include a memory storing executable instructions, and a processor configured to execute the instructions. The instructions may cause the computing device to display, on a display of a head mounted display (HMD) device, a virtual environment, detect, outside of the HMD, a first gesture input, generate, in response to detection of the first gesture input, a virtual notation surface, detect, outside of the HMD, a second gesture input, display, in response to detection of the second gesture input, the virtual notation surface as a virtual object in the virtual environment, detect, outside of the HMD, a third gesture input, annotate, in response to detection of the third gesture input, the virtual notation surface, and display the annotated virtual notation surface as a virtual object in the virtual environment.

In another aspect, a computer program product embodied on a non-transitory computer readable medium may have, stored thereon, a sequence of instructions. When executed by a processor, the instructions may cause the processor to execute a method, including displaying, on a display of a head mounted display (HMD) device, a virtual environment, detecting, outside of the HMD, a first gesture input, generating, in response to detection of the first gesture input, a virtual notation surface, detecting, outside of the HMD, a second gesture input, displaying, in response to detection of the second gesture input, the virtual notation surface as a virtual object in the virtual environment, detecting, outside of the HMD, a third gesture input, annotating, in response to detection of the third gesture input, the virtual notation surface, and displaying the annotated virtual notation surface as a virtual object in the virtual environment.
