A method of navigating viewable content within a virtual environment generated by a virtual reality system

摘要

A method of navigating viewable content within a virtual environment generated by a virtual reality system is disclosed. The virtual reality system comprises a display 13 for displaying the virtual environment comprising viewable content in a virtual reference frame to a user, and at least one head mountable sensor 14 such as an accelerometer or gyroscope for sensing a tilt of the user's head in a real reference frame. The method comprises the steps of moving the virtual reference frame relative to the real reference frame in response to the tilt of the user's head to present the viewable. Preferably, the rate or speed of movement of the virtual reference frame is governed by the tilt orientation and/or length of time the head is held in a tilt position. A control module 15 may present alternative interactions with the virtual reality system 10 by presenting two navigational modes, an input mode such as lists, menu options and a viewing mode presenting a portion or scene within the virtual environment both navigated using head tilts or head gestures.
