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.

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".
