Motivation: interaction in the near-field (arm‘s length)

Interaction at arm’s length;with 3D displays

What about gaze (and vergence)?

Vergence underestimates target beyond z=0 depth plane

Problem is worse at close distances

5CHI 2013 Workshop on “Gaze Interaction in the Post-WIMP World”, April 27, 2013, Paris, France.

How do we measure vergence?

6CHI 2013 Workshop on “Gaze Interaction in the Post-WIMP World”, April 27, 2013, Paris, France.

Vergence signal is noisy!

Filtering is needed to smooth signal

3D calibration is also necessary

7CHI 2013 Workshop on “Gaze Interaction in the Post-WIMP World”, April 27, 2013, Paris, France.

Calibration needed for both vergence and reaching

3D calibration adjusts gaze depth estimate

Calibration in VR may help reaching as well

How to test? Calibration for reaching...

How to test? Easing comfort via depth-of-field rendering
