Answer:
Step-by-step explanation:
The basic concept of virtual reality is that they are a pair of lenses in a headset that allows you to visualize a virtual 3D world and become immersed within it. To do the exercises correctly Anna would need to follow the following basic steps.
Put the virtual glasses over her eyes, complete the exercises in the virtual world, take the virtual glasses off
The headset/glasses need to fit comfortably on her eyes and around her head so that she can clearly see the image on the lenses and so that the headset/glasses do not fall off while she is completing her exercises. Once she is done with her exercises Anna can simply take off her virtual glasses and put them away.
