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.

Enhancements:

• 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.

Screenshots

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".
