Is cybersickness caused by sensory mismatch? In a new BioMotionLab paper, @SiaEftekharifar shows that motion parallax and stereopsis are both contributing, and that mismatches between the two depth cues do not. @vistayorku @YUResearch @YorkUScience
The role of binocular disparity and active motion parallax in cybersickness
Cybersickness is an enduring problem for users of virtual environments. While it is generally assumed that cybersickness is caused by discrepancies in...

Kudos to Adam Bebko. His workshop on bmlTUX, the BML Toolkit for Unity ExperimentsUnity, given at @VSSMtg drew an impressive crowd. For those who missed it, see the tutorials at https://biomotionlab.github.io/TUX/docs/firstoverview. @vistayorku, @YorkUScience, @InnovationYork
Congratulations, Michael et al. I remember this paper very well and often give it to students. Now I will also recommend MJB's notes (below) about its history. The most important message: "Do the work that you think is important and hopefully the community will agree in time".
I’m honored to share the 2020 Longuet-Higgins prize with @DeqingSun and Stefan Roth. It is given at #CVPR2020 for work from #CVPR 2010 that has withstood the test of time. I’ve written a blog post about the secrets behind “The Secrets of Optical Flow”: https://tinyurl.com/y89odrwf

Today's lab meeting at @BioMotionLab
with Xiaoye Michael Wang, Niko Troje, Ashley Funkhouser, Viswajet Kumar, Max Esser, Adam Bebko, Sia Eftekharifar, Anne Thaler, Saeed Ghorbani.
Using #VirtualReality in trial-based, factorial experiments in #VisionResearch can be cumbersome. In the BioMotionLab @yorkuniversity, we developed a toolbox for @unity3d that makes experimental design and execution easy and convenient. For details visit https://biomotionlab.ca/tux/

Here's my column on parks as the fulcrum points in the "constant, experimental push-pull between social norms and legal restrictions, trust and compulsion, freedom and constraint" -- and the pandemic-fighting importance of keeping them open.

Last day of the virtual @IEEEVR meeting. Michael Xiaoye Wang's avatar is looking at Anne Thaler's poster. Amazing how the conference organizers switched from real to virtual with just two week's notice. Anne's and Michael's papers are here: https://www.biomotionlab.ca/publications/
The hand tracking is cool. We are still working on it here in the @BioMotionLab @vistayorku @YUResearch. But we are getting close.
I use @htcvive, @optitrack, @pupil_labs and @KraftDinner to run experiments that provide information about how touch, proprioception, and vision come together to create the feeling of being inside a body. @VR_Neuroscience @InnovationCA #IAmInnovation #Contest
Here is a wonderful visual illusion that achieves what visual illusions are supposed to achieve: It challenges the trust into your very own senses.

Perception goes Twitter! I still consider it one of the finest journals in our field as it stays faithful to its almost 50-year old tradition to publish unconventional, creative, adventurous research.
Hello world!
And hello 2020. This year Perception is 48 years old, and its open access sister journal i-Perception turns 10. For the new decade we have a shiny new Twitter account for papers, discussion & news from both journals on Special Issues, prizes, new formats, and more.
This is a gem! Not only will it replace how we teach high school students to solve quadratic equations, but we should also point out to them, that new, exciting discoveries may not require deep digging, but rather open eyes and a curious mind to spot them.
A new way to make quadratic equations easy - Cool trick. https://www.technologyreview.com/s/614775/a-new-way-to-make-quadratic-equations-easy/
Congratulations to Johannes Kurz who collaborates with @BioMotionLab from @jlugiessen. His new paper shows how body structure helps to interpret body motion in the context of soccer penalty shooting. Ask us for a reprint, if you don't have access.

Happy to have Larry Maloney here who arrived for the first of a series of visits support by a @vistayorku travel grant. He excited the students in the @BioMotionLab with his crystal clear talks and then gave another seminar to the larger CVR community.
Our sense of touch is at the center of nearly everything we do. Katherine J. Kuchenbecker, Director of the #HapticIntelligence Department, aims to sharpen our understanding of haptic human-machine interaction. She was interviewed @IROS2019MACAU #IROS2019:
#iccv19 reached a productive and happy ending. many thanks to amazing colleagues @PerceivingSys, and our wonderfull coauthers for #amass.
Naureen and Nima working hard to serve the crowds at @ICCV2019 today 10:30-13:00, Hall B, Poster 102. #AMASS: Archive of Motion Capture As Surface Shapes. More here: https://amass.is.tue.mpg.de
It was very nice to reconnect with the @PerceivingSys group at @ICCV19 in #Seoul.
Our first ever alumni event in #Seoul, #Korea @ICCV19! Thank you @Michael_J_Black and all the great helpers and people who make @PerceivingSys what it is - a great place with great people
Congratulations to Anja Cui who successfully defended her PhD thesis today. Anja, I am very happy you contributed so many years to life in the BioMotion Lab. Congrats to your new postdoc position in Janet Werker's lab @UBC.

What does VR add to the picture?
I am pleased to see my editorial "Reality Check" in the newest edition of the journal Perception:

Want to train deep networks to model 3D human pose and motion? AMASS is a new dataset with 45 hours of mocap - and growing – all in SMPL format. Tutorial code shows how to use AMASS for deep learning. To appear: #ICCV2019 data: https://amass.is.tue.mpg.de/

Both sex and weight can be decoded from body- and face-responsive brain regions. https://www.sciencedirect.com/science/article/pii/S1053811919306731
Before OA, publishing costs were covered by library subscriptions. With OA, they shifted to authors, leaving costs for non-OA contents with libraries. Here, BOTH rest on research institutions. Will they ask authors to dip into their grants to get it back?
More than 700 German research institutions strike open-access deal
Agreement will make thousands of German-authored papers available free worldwide every year

AMASS, the largest database of motion capture data is finally online and working beautifully. Represented in the common format of SMPL it provides kinematics but also individual body shape. The system comes with tutorials and helpful code, too. https://amass.is.tue.mpg.de/

Goals
Our main research interest is focused on questions concerning the nature of perceptual representations. How can a stream of noisy nerve cell excitations possibly be turned into the coherent and predictable perception of a “reality”? We work on questions involving the processing of sensory information, perception, cognition and communication.
Topics
People perception: The biology and psychology of social recognition
- detection of animate agents
- conspecific recognition
- gender recognition
- individual recognition
- action recognition
- recognition of emotions, personality traits and intentionality
- recognition of bodies, faces, and biological motion
Vision in virtual reality
- pictorial vs physical spaces
- space perception
- simulator sickness
- perception of self-motion (vection)
- multisensory integration
- perception of the own body
- the nature of presence
Visual ambiguities and perceptual biases
- depth ambiguities
- the “facing-the-viewer” bias
