If the icon to the right isn't a "C", the wiki's svg handling is still broken.
Summary
One XO shows an eye chart (8-way Landolt-C), another XO serves as a remote control for input (using the 8-way d-pad).
This is intended to develop into an aid for layperson peliminary vision screening.
Status
Things needed for a release:
- tubes support, and a remote control mode
- handling the d-pad keys
- try on a real xo
I've been pulled away to other things, so there's been no progress since mid July. Volunteers, or someone to take it over, would be welcome.
Next:
- better test driver (chooses which size "C" to show next)
- better choices
- recognize when data is sufficient
- clearer report graphic
- give an acuity number, rather than relying on the user to interpret the graphic.
Nice to have:
- Gathering results to one xo.
- ...

Misc
Issues to elaborate on:
- peeking
- illumination
Ideas:
- Include a gap-less ring in both training and testing. With any direction being correct. To make "inability to see gap" feel less like "failure".
