HW4 (for Cardboards): Bad Design, UI Havoc¶

Due date: 2025-11-28 23:59.

Download¶

Start with downloading the following VR Cardboard application:

BadDesign.apk

For Students with Their Own HMDs¶

Please complete the alternative HMD-based assignment.

Find Design Flaws¶

The objective of this assignment is to help you better understand and recognize bad and good design practices when it comes to user interaction, UI, and UX in VR applications. After downloading the above file, make sure to use the correct QR code that you generated in HW1 when running the application. To interact with the environment in this apk, you’ll use the "gaze" method, which involves looking at an interactive object or button and waiting for about a second.

The application contains seven scenes. Each scene contains one bad design practice. Your task is to recognize these design problems and answer our questions about what you see/perceive the issue are, and how things could be done differently to improve user experience in VR applications.

This homework can also be seen as an inspiration for your final project, in which you could implement more perceptual flaws/tunings/illusions of your choice.

Question 1¶

When designing menus, mention one bad design choice in Scene 1.

Question 2¶

Mention one bad design choice in Scene 2.

Question 3¶

What would be the most effective way to reduce the discomfort in Scene 2?

Question 4¶

There is one design choice problem in Scene 3, what would fix it?

The use of too many objects (grass) in the scene causes a drop in FPS. Using a more powerful GPU would improve the comfort.

The scene is well designed.

The grass follows your head motion, it happens when the hierarchy of objects in Unity is not correctly implemented. Fixing the hierarchy in Unity will eliminate the problem.

Reducing the number of objects in the scene would help with dropped frames.

Ask the user to not look at the grass.

There is a yaw drift in the scene that can be correct by a better tracking algorithm.

None of the above.
