Viewing and interacting with the world is different in the simulator in comparison to the headset. First, when interacting with the world in the simulator, it is controlled through key clicks. This means in comparison to the headset where you are able to walk around the scene, you lose some precision in the simulator. Additionally, in the simulator, I often found that it was a little bit less intuitive. While in the headset, most things mimicked real life. For example, the buttons needed to pick up an item were on the side, and to navigate you physically walked through the scene. In comparison, on the simulator to pick up objects you first have to press 1 or 2 for either the left or right hand respectively. Then, this locks your full body movement and allows you to move each hand individually. Then you have to navigate to the object, press the mouse to pick it up and if you are done, then you can exit the hand by pressing 1. However, when navigating this I found it easy to overshoot the target that I was trying to pick up with the “hand” controller” and ended up inside a drawer or being distant from the target. Additionally, unlike in the headset, I found it near impossible to hold two objects together and hit them against each other. In my scene, I made it so all the individual potion bottles had accurate physics and could be picked up and when they collide with an object or are grabbed they make a clinking sound. However, this was difficult to test in the simulator and was a lot easier to test in the headset. In the headset, it was easier to not only target the object but ensure that the item remains held while you picked up the other.

With the headset, you are more interactive and involved with the environment in comparison to the simulator it meant that it was easier for me to see faults in the scene as I could move my perspective around a lot easier. For example, in development, I managed to lose a pie when I applied physics and I couldn’t figure out why. When I tried on the headset, I was able to look in the oven and realized, it had fallen through. I then added colliders to the oven to prevent the pie from falling to the ground. Another example of this was if something was floating, I found it easier to look at different angles, and then adjust as needed.

Another major difference in how interacting and viewing the world is different in these two methods is also perception. In the simulator, the view is on a plane. There is no peripheral vision and you don’t have to get as close to items in the simulator. Additionally, as the screen in the headset is closer to the eyes, I found my eyes getting more tired viewing the world in the headset in comparison to the simulator. Additionally, while the frame rate was still decent in the headset, the processing power on the simulator was a lot better, leading to smoother walking around, and you had fewer concerns about teleportation as there was less of a chance that your body would collide with an object. Finally, the simulator required less time to interact with the environment, so it was useful if I was doing quick checks of the environment.

1. Download the project from Github and unzip the file

2. In Unity Hub ensure the version is correct click open and click on the now unzipped main folder

3. After opening, there should be a blank scene

4. Navigate to the Assets folder

5. Inside the folder there is a scene called Fall Scene drag and drop into the heirarchy

6. Delete the Untitled Scene, Fall Scene should be the only scene in the heirarchy.

7. Now you should have the scene fully loaded.

• For playing scene in Unity

  1. Ensure that CameraRigs.SpatialSimulator is enabled and UnityXRPluginFramework is disabled. One can do this by clicking Toggle Active State

  2. Click play on the top hand bar.

  3. To navigate use keys W to move forward, S to move back, D to move left, A to move left

  4. Press keys 2 and 3 to select the right or left hand respectively.

  5. Then uses W, S, A, D to move the hand/controller to the right place.

  6. Press on the mouse if you wish to press on an item.

  7. If you are done using the hands/controller press key 1

• For playing scene on Oculus Quest Headset

  1. Ensure that UnityXRPluginFramework is enabled and CameraRigs.SpatialSimulator is disabled. One can do this by clicking Toggle Active State

  2. Under File in the top bar, open Build Settings

  3. Connect the Oculus Quest to the computer with Unity via cord

  4. Click on Android and under Run Device make sure to select the Oculus device being used/device that is connected

  5. Ensure that permissions are allowed on the Oculus to connect to computer

  6. Click Build And Run

  7. Once you set up any boundaries need it should be running!

  8. If not, on the Oculus go to Apps and under the filter where it says All click and scroll down and click where it says Unknown Sources.

  9. Click on P2.angelica_villegas salzar. The application should now be running!

  10. Navigate by either walking the scene, or teleporting using the joystick in the righthand (move green dot to place and click to move)

  11. To pick up/drop off items, click the buttons as if you are grabbing the item.

Congrats!! You should now be able to navigate through the scene that was created!
