As the animation I am creating is driven by the short story present within, I do not believe that it would benefit from having user embodiment. As well as that, the animation would not benefit from user embodiment due to the limited user interaction within the animation.
Taking into consideration cyber sickness as well as motion sickness, I have made the movement and transformation within and between scenes simple. When transitioning between the bedroom and space scene, the walls below will fall and the ceiling will rise. When transitioning back to the bedroom from the space scene, the room will rise back up and the ceiling will set in place above. No effects are used within the animation that gives the impression of the user moving as another preventative of cyber sickness. Only assets within the scene will move, assets in the bedroom rise, rotate and alter scale. These movements are not enough to cause the sickness of a user. Within the space scene, the large moving planets could have been a cause of sickness. To prevent this I have no added motion blur to them, adding this could have improved the overall look of the scene but due to the sickness it may cause I have not.
