Kinect Dyadic Distance App
A short screencast of my Kinect Dyadic Distance App in action at Johan Nieuwenhuize’s studio. The app makes use of the live data streams from a Microsoft Kinect motion sensing device to continuously calculate the …
Lock-in Amplifier Game at Physics@Veldhoven
Last week Maurits, Davide and I had a great time demonstrating our “Flappy Bird” game at the Physics@Veldhoven conference. “Flappy Bird” invites a player to wave his or her arms in a rhythm set by …
Qualtrics wide to long export file conversion
While helping out with the implementation of a slightly tangled Qualtrics survey, I needed to develop some workarounds that might be of use to others – so I thought I’d share them with you here! …
Our paper “Tracking the decoy” has been published!
Really happy (and proud) that our paper on the application of lock-in feedback for optimal placements of decoys has just been published – written in close collaboration with Prof. Davide Iannuzzi and Dr. Maurits Kaptein. …
Face ratio optimization
Do you like average faces best? Adjust the sliders and find out! * If you find the avatars at the center of the feature space more attractive than those at the perimeters, you are …
Lock in Feedback in two dimensions
A visualization demonstrating how Lock in Feedback (LiFt) is able to optimize over multiple dimensions – here, optimizing the position of a decoy on two attributes. If you are interested in playing around with Lock …
Online continuous decoy optimization
April 2016: We have removed Qualtrics from our experimental workflow, and have instead chosen for a custom Drupal based survey engine. As time went by we needed more and more workarounds to get our code …
Decoy Effect LiF simulation in R
We ran the R simulation below to test our hypothesis that LiF should be able to optimize decoy effects (I will add comments further clarifying my train of thought as reflected by the script within …
