This model is not generally not built to be passive, it should then interact with reality to alter the nature of reality. It’s an interesting feedback loop called “active modelling”. If we don’t…

The Binocular Suppression scene is now designed well enough that it not only demonstrates the suppression switching on very well (by introducing conflict), but allows us to find that breakthrough point where – despite the suppression – Mr R can see…

EyeSkills Prototype for Lazy Eye – Iteration 2 – Practitioner View

A first quick look at how the second iteration of the open-source EyeSkills prototype works. This prototype is designed to test the visual abilities of a person with Lazy Eye, and evaluate the effectiveness of a few techniques which may be useful in allowing a participant to re-establish binocular vision.
