Quiz 3 - VR Ergonomics & Optimization thumbnail

In this quiz, you will test the knowledge and skills you learned in Unit 3 related to VR Lighting and Optimization.

This quiz is part of the Create with VR course.

Question 1

Which of the following would make your app LESS comfortable for users?

Select only one

During continuous motion, apply a black vignette around the edge of the screen to reduce the field of view.

During teleportation, fade to black to reduce the sense of vection.

Slowly fade in at the start of the scene so that the user does not suddenly find themselves in a new room.

Decrease the frames per second (FPS) so that the image does not change as quickly.

Question 2

True or False:

Providing users options to choose between several types of locomotion increases accessibility.

Select only one

True

False

Question 3

Which one of the following tends to improve performance?

Select only one

Post-processing

Real-time lighting

Static batching

Fog

Question 4

Which one of the following Unity tools is NOT used to diagnose performance problems.

Select only one

The Rendering statistics window

The Profiler

The Frame Debugger

The Timeline

Question 5

Which of the following techniques would likely DECREASE draw calls (batches)?

Select only one

Sharing one material over many objects.

Using anti-aliasing.

Using anisotropic filtering.

Increasing your number of triangles.

Question 6

Which of the following are true about lighting modes?

Select all correct answers.

Select all correct answers

Objects must be set to static for lightmapping.

Lights must be set to Realtime mode for lightmapping.

Mixed Lighting allows for real-time shadows.

To see the effect of Light Probes, you have to bake your lighting.

Question 7

Looking at the two images below, what can you tell about their lighting settings?

Select only one

Image 1 has a lower Lightmap Resolution than Image 2.

Image 1 will take longer to bake than Image 2.

Image 1 has a lower number of Direct Samples than Image 2.

Image 1 has a lower number of Bounces than Image 2.

Question 8

Which of the following are true about graphic quality optimization in Unity?

Select all correct answers.

Select all correct answers

Mip maps should be used for high-resolution textures that might be seen from far away.

Anisotropic filtering should be used to improve the quality of textures seen at an angle.

Texture Atlases help make images clearer when they are moving at high speeds.

Using lower resolution images can decrease the number of triangles in your scene.

Question 9

What does Anti-aliasing do?

Select only one

It optimizes your textures to improve frame rate.

It simplifies far-away objects to reduce the number of triangles.

It optimizes draw calls by batching together objects that share the same texture.

It smooths out jagged edges on curved and diagonal lines.

Question 10

Which of the following would actually DECREASE the accessibility of your VR app?

Select only one

For mobility / motor accessibility, make sure all actions require two hands.

For hearing / audio accessibility, add closed captions to any critical audio instructions.

For vision accessibility, make text instructions large and clear.

For cognitive accessibility, include directions or tutorials for how to use your app.
