  "description_excerpt": "The present disclosure is generally related to virtual technology and, more particularly, is related to systems and methods for providing user interaction in a virtual environment.\n\nLarge scale Immersive Virtual Environments (IVEs) are common in current research. Some of the major problems in large scale IVEs, however, are traveling and navigation. These problems has been addressed by input devices such as handheld and fixed station user input devices as well as environment specific devices such as, for example, a virtual reality snowboard. The utilization of these input devices, however, is awkward or unnatural and may require extensive training, especially if the device offers many degrees of freedom. For example, some of the previous input devices have required the user to memorize and perform specific coded gestures or sequences of gestures to make virtual environmental changes such as a direction or mode change. In such a device having many degrees of freedom, the user is tasked with memorizing and performing many potentially unnatural tasks and gestures to travel and navigate within a large scale IVE.\n\nEmbodiments of the present disclosure provide a system and method for teleportation in a virtual environment.",
