Project: Simulator sickness

In collaboration with Nokia Research we investigated if spatial sound causes effects of simulator sickness (or motion sickness (there is a lengthy discussion about whether simulator sickness is a form of motion sickness. Therefore we will refer to what made people sick during our experiments as "simulator sickness")).

We started off with a recording made with an improvised binaural recording device (the head) mounted on a manipulated record player that allowed seamless speed manipulation. We compared the binaural recording to a stereo recording (made with a Zoom H4) and found it worth to take a closer look at.

At Nokia Research in Helsinki we rebuilt the initial setup but used 5 Genelec 8240A
speakers emitting various sounds (music, human voices, environmental noises), real human head wearing an Augmented Reality Audio headset for the binaural recording, and a soundproofed studio.

We ran a study on 82 participants and compared random to predictable to no movements at all.

Listen to what they have listened to (shortened and lower quality). Oh, and be warned - it's in Finish.
This is for regular left to right movements:

And this is an example of random movements:
