A virtual reality (VR) system includes an image playback system that sends
images to an image viewing device, such as a pair of display glasses.
Each image has a 360-degree field of view. An user views a portion of the
images. The portion of the image viewed is determined by a directional
sensor mounted to the display glasses. The images are advanced according
to a speed sensor attached to a moving device, such as a stationary
bicycle. The VR system simultaneously coordinates the portion of the
images viewed by the user by coordinating signals from the directional
sensor and the speed sensor.
