Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for implementing a driving simulator are disclosed. In one aspect, a method includes the actions of receiving, by a virtual reality headset, sensor data that reflects characteristics of a user wearing the virtual reality headset. The actions further include, based on the sensor data, determining, by the virtual reality headset, that the user is likely experiencing motion sickness. The actions further include, based on determining that the user is likely experiencing motion sickness, activating, by the virtual reality headset, a vibration device that is configured to provide vibration feedback to a body of the user.

Abstract: A head mounted display (HMD) for viewing a virtual environment generally include a flat display (FD), lenses for focusing on the FD, and a housing to enclose the FD and lenses. The housing is generally opaque to block out all external light, so the viewer only sees light from the FD. By making a portion or all of the housing translucent or transparent, ambient light and other external light can be seen by the viewer, providing additional visual cues and a larger perceived field of view. Additionally, other people can see light from the FD. The lenses are configured to view the FD and parts of the translucent housing.

Abstract: A head-mounted display (HMD) allows a user to view a virtual environment. The HMD displays a field of view to the user. However, the user may experience simulator sickness or motion sickness from viewing the field of view. The HMD is connected to a sensor which can monitor the user. By monitoring the user's physiological state, the user's simulator sickness can be detected or predicted. To reduce the negative effects, the field of view can be throttled. The field of view can also be throttled in order to provide a better user experience even if the user does not experience sickness.

Abstract: A head-mounted display allows the user to view a virtual environment. The head-mounted display is made of a pair of lenses which is directed to a display encased within a housing. However, the display provides a limited field-of-view that is less than what the user sees in a real-world environment. Adding an illuminated frame around the display's periphery can enable the user to produce spatial judgment similar to having a larger field-of-view. The illuminated frame does not require additional processing.
