US Patent 10019131 Two-handed object manipulations in virtual reality

Systems and methods are described for generating a virtual environment including at least one three-dimensional virtual object within a user interface provided in a head mounted display device, detecting a first interaction pattern and a second interaction pattern. In response to detecting the second interaction pattern, a modified version of the three-dimensional virtual object at the first virtual feature is generated according to the first interaction pattern and at the second virtual feature according to the second interaction pattern. The modified version of the three-dimensional virtual object is provided in the user interface in the head mounted display device.
