Thanks again for the advice. I live in England, I'm sure there is something similar regarding caption call app. Ultimately I'm looking forward to Augmented reality with realtime transcoding for subtitles/close captioning. As long as i can read the text above peoples heads, similar to speech bubbles would make a hell of a difference understanding others.
As for my DJ virtual turntables. The idea behind them is to use in virtual reality with finger tracking. So they work just like the real world counterpart. I have the drumkit working already using oculus touch controllers. I'll try and wire up the synth next, but that will be more problematic because of my hearing or lack of. Thanks again for the kind words about my project and thank you for the advice. I appreciate that very much.
