Systems, apparatuses and methods for outputting fields of view of a virtual reality system according to postures of a user of the virtual reality system can include a sensor for detecting a posture of the user of the virtual reality system and a display for outputting data indicative of a field of view according to the user's posture. When the sensor detects a user's posture, the virtual reality system can display an alternate field of view that indicate to the user that the posture has been detected. When the sensor no longer detects the posture, the virtual reality system can display the original field of view again.
