We incrementally added features to move in the direction of your gaze, gravity, solid-object collisions, and use head gestures to start and stop walking. We made adjustments for camera height and explored the relationship between a first-person head versus a body in virtual reality. Lastly, we reviewed some of the factors that VR developers should think about to provide a comfortable VR experience and avoid motion sickness.
