Ways for controlling a virtual-scene view in a portable device are presented. In one method, a signal is received and the device is synchronized to make the location of the device a reference point in a three-dimensional (3D) space. A virtual scene with virtual reality elements is generated around the reference point. The current position of the device in the 3D space, with respect to the reference point, is determined and a view of the virtual scene created. The view represents the virtual scene as seen from the current position of the device with a viewing angle based on the position of the device. The created view is displayed in the device, and the view of the virtual scene is changed as the device is moved within the 3D space. In another method, multiple players shared the virtual reality and interact with each other in the virtual reality.
