Hi everyone,
I'm new to the list and am glad that there is such an active community focused on accessibility.
I've developed an iOS app for those with low vision and would like to interface it with a refreshable braille display and use its keys (for dots 1 to 6) as input. In order to do this, the app needs to determine exactly which keys has been simultaneously pressed.
One way to do this would be to capture the ASCII braille output from the braille display in an UITextField, whereby each key combination would result in a unique ASCII character. Unfortunately the 8-dot uncontracted braille setting does not translate to ASCII braille 100% of the time (e.g. dots 4-5-6 should result in an ASCII underscore symbol, but instead calls a backspace/delete action within the UITextField).
Also, I'm not sure if there is a way to access the output of the braille display prior to it being translated by VoiceOver into text.
I would appreciate any help or insight to integrate a refreshable braille display to improve the accessibility and usability of the app.
Thanks in advance for your advice :)
