  • Patent number: 12061790
    Abstract: Some examples provides a set of frameworks, process and methods aimed at enabling the expression and exploration of free-form and parametric 3D shape designs enabled through natural interactions with a hand-held mobile device acting as a controller for 3D virtual objects. A reference plane in a virtual space generated by the location of the mobile device may be used to select a 3D virtual object intersected by the reference plane. Positioning of the mobile device may also be used to control a pointer in the virtual space. In an example, the orientation of the mobile device may be detected by an accelerometer or gyroscope. In example, the position of the mobile device may be detected by a position sensor.

  • Patent number: 11543933
    Abstract: A method of manipulating a three-dimensional image file including a virtual object includes obtaining image information in a processing device of a non-instrumented physical object manipulated by a user, such image information including movement information; and causing virtual movement of the virtual object based on the movement information. A method of shaping a virtual object includes obtaining image information including movement information; and determining a shape of the virtual object based on the movement information. A method of modifying a virtual object includes obtaining image information including movement information; and altering a virtual surface appearance of at least a part of the virtual object based on the movement information. Systems and computer-readable media are also described.

  • Patent number: 11475651
    Abstract: A virtual reality system, comprising an electronic 2d interface having a depth sensor, the depth sensor allowing a user to provide input to the system to instruct the system to create a virtual 3D object in a real-world environment. The virtual 3D object is created with reference to at least one external physical object in the real-world environment, with the external physical object concurrently displayed with the virtual 3D object by the interface. The virtual 3D object is based on physical artifacts of the external physical object.
