Sense of Scale?

Size? Distance?

Scale in 2D

Conveying Scale

  • Familiar objects
  • Relative size
  • Parallax

Parallax

Parallax is the relative movement of objects as a result of a change in point of view

Parallax

Assumptions

  • Familiar objects - assumes normal size
  • Relative size - assumes at same distance
  • Parallax - assumes objects are stationary

Scale in Real Life

Vergence

Assumptions?

  • Vergence - assumes a fixed distance between the eyes

Interpupilary Distance

Interpupilary distance, or IPD for short, is the distance between the pupils of your eyes.

Interpupilary Distance

  • Real IPD
  • Virtual IPD

Scale in VR

Virtual IPD

This parameter is now back in the hands of the artist

Scaling or Vergence?

Experiments

Experimenting in Tuscany

  • Scaled Virtual IPD
  • Player height
  • Neck model parameters
  • Player speed

Warning and Conclusion

  • Dynamic scaling causes eye strain!
  • New phenomenon
