A head mounted virtual reality (VR) device including an inertial measurement unit (IMU) is located in a vehicle which may be, and sometimes is, moving. Detected motion attributable to vehicle motion is filtered out based on one or more or all of: vehicle type information, information derived from sensors located in the vehicle external to the head mounted VR device, and/or captured images including a reference point or reference object within the vehicle. An image portion of a simulated VR environment is selected and presented to the user of the head mounted VR device based on the filtered motion information. Thus, the image portion presented to the user of the head mounted VR device is substantially unaffected by vehicle motion and corresponds to user induced head motion.
