Refactoring for flexibility

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…

Mastering eye realignment by watching videos! – An interesting community suggestion

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.

A metaphor for strabismus and amblyopia

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.
