In this quiz, you will test the knowledge and skills you learned in Unit 1 related to VR Basics.

This quiz is part of the Create with VR course.

Question 1

If you are targeting a mobile VR headset (as opposed to a tethered headset), which scriptable render pipeline (SRP) is most appropriate?

Select only one

The Universal Render Pipeline (URP)

The High-Definition Render Pipeline (HDRP)

The VR Render Pipeline (VRRP)

The Mobile Render Pipeline (MRP)

Question 2

When a VR Device claims to support “6 Degrees of Freedom” (6 DOF), what is “6” referring to?

Select only one

The 6 degrees of freedom are:

1. Move head

2. Move left controller

3. Move right controller

4. Rotate head

5. Rotate left controller

6. Rotate right controller

The 6 degrees of freedom are:

1. Move up

2. Move down

3. Move left

4. Move right

5. Move forward

6. Move backward

The 6 degrees of freedom are:

1. Move along x axis

2. Move along y axis

3. Move along z axis

4. Rotate about x axis

5. Rotate about y axis

6. Rotate about z axis

Question 3

Which of the following can be done through the Package Manager window?

Select all correct answers.

Select all correct answers

Add the XR Interaction Toolkit package, which enables you to more easily develop for VR.

Add the XR Plugin Management package, which allows you to deploy to different VR devices.

Configure your Build Settings in order to deploy to your device vs the device simulator.

Configure whether your scene is using either 3 DOF (Degrees of Freedom) or 6 DOF.

Question 4

You have an empty Unity scene with only a Directional Light and a Main Camera in it.

What would happen if you added an XR Origin object to that scene?

Select only one

The Main Camera is duplicated so that there is one for each eye.

A new object is added called an XR Origin and the Main Camera is made a child object of the XR Origin object.

The Camera component on the Main Camera is replaced by an XR Camera component.

The Directional Light is removed from the scene, since it cannot be rendered in VR.

Question 5

Listed below are four types of locomotion that are possible in VR.

Which two of these are least likely to induce simulator sickness?

Select the two correct answers.

Select all correct answers

Physical (Room-scale) movement - the user physically moves in the real world in order to move in VR.

Continuous (Controller) movement - the user uses a thumbstick or D-pad to smoothly move through the scene.

Scripted movement - the user is automatically moved around the scene, controlled by a script.

Teleport movement - the user clicks and is instantly transported to a new location.

Question 6

You want to make a ball that the user can grab and throw around the scene. The ball should bounce off of the walls and floor.

Which components and properties would the ball likely have?

Select all correct answers.

Select all correct answers

A Sphere Collider with “Is Trigger” enabled.

A Physics Material assigned to the collider.

“Is Kinematic” enabled in the Rigidbody component.

“Use Gravity” enabled in the Rigidbody component.

An XR Grab Interactable component with “Kinematic” movement type.

Question 7

You made a socket interactor for a phone charging dock in VR. However, the phone object is not snapping to the socket.

What could possibly explain why this is happening?

Select all correct answers.

Select only one

The collider does not have “Is Trigger” enabled.

The collider is a box collider instead of a sphere collider.

The socket and the phone interactable only share one interaction layer.

The socket has a Rigidbody component.

Question 8

In the screenshot below, you can see the way the hand should be oriented when it picks up the lantern.

The local direction of the lantern is shown by the axis gizmos in the image.

Which of the following orientations for an Attach Point for this lantern would achieve the desired effect shown in the image?

Select only one

Green arrow pointing forwards and blue arrow pointing right.

Green arrow pointing left and blue arrow pointing forward.

Green arrow pointing forward and blue arrow pointing down.

Green arrow pointing forward and blue arrow pointing up.

Question 9

Which of the following is true about mobile vs tethered headsets?

Select all correct answers.

Select all correct answers

A mobile headset can support higher-end graphics than tethered headsets.

A tethered headset gets its processing power from a gaming console or computer.

A tethered headset supports 6 degrees of freedom (6DOF), while mobile headsets do not.

Some mobile headsets can be plugged in and operate as tethered headsets.

Question 10

What does “XR” stand for?

Select only one

Extreme Reality

Extra Reality

External Reality

None of the above
