    Updated Version

    Realizing the more steps involved the more a pain, I recreated the Sloan fonts and turned my images into fonts as well which significantly reduces the size. I also base 64 encoded the one image I had to reduce the package an additional file. The total package is almost 80% smaller then the original and only requires the one download with a version of my font included.

    The font is not FREE, it can be used in a commercial setting. I prefer no other distribution outside of Optiboard without permission and it cannot be packaged into any other application without express consent.

    Directions for Use:

    1. Unpack the Zip file into a folder DOWNLOAD --> openacuity.zip <--
    2. Open the file openacuity.html into a current html5 browser (Chorome or Firefox)
    3. (FIRST USE) Run Calibration from the menu see video below
    4. Use the "+" to increase letter size
    5. Use the "-" to decrease letter size
    6. Additional features can be accessed through the menu see video below.

    Where were you before I installed Ipads in my walls and bought ipod touches to control them through bluetooth?

    This would have been much cheaper to implement.

    Sorry bro wish I knew I had been sitting on this for some time but the need came up recently in our office so I polished it off. That's an interesting idea controlling with a touch enabled device. I have been using an infrared usb dongle, you just gave me an idea.

    Use an android tablet and cast it to a chromecast tv dongle connected to a flat screen. I'll have to whip up another version. I have one now on a raspberry pi that boots straight to a modified version of linux and chromium that is completely chromeless so the VA chart is displayed and nothing else.
