A collection of interesting videos about accommodation/vergence issues in VR headsets, and how to work around them using light fields and binocular suppression(Monovision !!!)
I am really quite fascinated by when and what causes suppression. We can see from our quite simple approaches to triggering conflict that the idea of conflict neurons seems to make sense – but there are so many ways we could potentially test the edges of when and why conflict occurs, and push those boundaries.
We will presenting our open-source software for unlocking Stereo Vision at the WMIT conference in Wonju (South Korea) on the 5th of September, should you happen to be in the neighbourhood!
A prototype is, well, a prototype. It breaths life into an idea, it takes an interactive form, and this generates new ideas and insights. Alongside functional ideas and insights (hey! wouldn’t it be cool if the user could do *that*!) – are engineering ideas and insights (hey! wouldn’t it be cool if we could make it do *that* more quickly/flexibly/reliably)!
Now that most of the functionality I wanted is in place, I’m literally losing sleep over those engineering insights…
Thanks to a great suggestion from Rafal in Poland, I have a first working version in which a participant can watch video in way taking into account both their eye misalignment and also the binocular suppression ratio needed to get both eyes working. When they click “ok”, the video screen on the strabismic eye starts to straighten up, very slowly and gradually.
I wondered how fast we could use the EyeSkills framework to implement a basic first version of a measurement tool. The answer? Very fast.
Strabismus and Amblyopia are like a lock, which evolution has put in place to enforce monocular vision once a problem with binocular vision has been detected. We are learning how to pick that lock, how to open the visual system back up to a point where a person has a second chance at learning how to use both eyes again.
Some more interesting changes to Iteration 2 after another user test with Arthur! It is coming together nicely.
Each user test is an exciting event. Each user test throws up at least half a dozen “aha” or “why didn’t I think of that” moments, driving on and further inspiring development. In our most recent user test (yesterday evening with Mr R) there were some obvious but useful minor improvements we could make to help practitioners, and a couple of major issues were also raised about determining what the participant is really perceiving.
