QUIZ: Vestibular System¶

Due date: .

Topics:

Vestibular System
Optic Flow
Vection
Orientation tracking
Tilt drift correction
Yaw drift correction
Tracking with a camera
Perspective n-point problem
Filtering
Lighthouse approach

Assumptions:

When the term "vection" is used in the questions below, it specifically refers to visually induced vection. For optic flows, use the following coordinate system:

Comments or Concerns¶

Leave any comments about the questions below here. For example, if any of the questions seem unfair, or confusing. This is not a graded question, you don't have to write answers here.

Question 1¶

Which part of the vestibular system measures linear accelerations?

Question 2¶

Which of the following is the main reason for sickness in VR?

Question 3¶

Which one of the following statements is FALSE about VR screens?

A slow-switching LCD display causes blurring (judder) of the stationary objects to be perceived as the user turns their head.

Increasing frame rate, spatial resolution, tracking accuracy, and FOV will increase realism, and therefore, decrease the amount of VR sickness.

Aliasing problems are worse for VR than for ordinary graphics on a computer monitor.

Even for a 180 Hz refresh rate VR display it is possible to perceive the frame rate if objects in the virtual scene move fast enough.

Lower persistence displays reduce judder (motion blur) in VR, as they decrease the amount of time during which retinal slip occurs.

None of the above.
