Aniseikonia Control

Some quick notes.  Aniseikonia is basically when one eye sees the world at a different scale to the other.

You can start the scene in EyeSkills, but you need a bluetooth keyboard attached.

The keys “awdx” are mapped to “left, up,right,down” respectively.

Press and hold either left or right for 3 seconds, then release. This will select which eye is strabismic and/or for which you want to try repositioning the world view.

If you then do a short press on left/right it will change what you look at.

Up/Down will move the object for the released eye further away or closer (making it larger or smaller).

See if you can make the two images fuse, and if so.  Let us know your experiences here :


Universe of Discource – VR Headset

To avoid confusion, we’re trying to settle on a useful set of terms to describe what we’re talking about when it comes to designing our VR headset.

Here’s the current diagram – it will evolve I’m sure:

Issues with git submodules

So, the EyeSkillsCommunity app has the EyeSkillsFramework as a submodule in Assets/EyeSkills/Framework.

When you first check out the submodule it is in a “detached state” which means that changes can’t be resubmitted.

The Hackaround I found is to make changes, commit them (remember the commit id) then :

git checkout master
git pull [5......4092ef...]
git push

A Manifesto

“Eye Skills, You Skills, We all got Skills for …”


Basic questions remain unanswered about what Lazy Eye really is, and how able different people are to overcome or moderate its effects.


It is our mission to empower the Lazy Eye community to collectively contribute to answering these questions.


For the last years this project has been funded privately, and with the support of the We have done this because my wife and I decided it mattered, and we could help make a difference. It has now outgrown us, and our resources. It now needs the right structure which will lead to permanent, ongoing efforts to improve and develop the system.


I believe it is necessary to consider four different groups of people in order to create a self-sustaining eco-system which can accelerate research and best-practice treatment. Here are some of the objectives I believe EyeSkills should strive to reach:


First, we the community, must take on the role of basic experimenters and hypothesis generators. This is why there is a community app for individual exploration and experimentation.  An derivative version for community trials/multi-person experiments can be developed from this.


Secondly, we must turn these hypothesise into potential research projects for scientists. It must be simple for researchers to build exactly the experimental environments they need to conduct repeatable open-science. This is why the framework is abstracted out.


Thirdly, we must make best-practice available at affordable levels around the world, which in turns feeds back into cohorts for high-quality science.  This will require social entrepreneurship and investment to set up distribution structures.


Finally, armed with hard evidence and professional commercial support, we must shift the treatment paradigm by helping Ophthalmologists move from just treating eyeballs to helping patients train their own visual system – without adding to their already overburdened daily regimes.


I hope you will join us in working to provide a viable alternative paradigm for understanding and working with Lazy Eye.

Designing for a better understanding of alternating strabismus conflict zones

Now that we’re increasingly certain that alternating strabismus is something in its own right, with different perceptual side-effects to “regular” fixed strabismus, we’re starting to think about how we could better understand/categorise/explore what those perceptions are in a way that can be reliable reported….

Here are some initial ideas one the very simplest first steps we could take:
