Progress???? in General discussion Posted July 11, 2019 · Report reply 8 hours ago, Contrabombarde said: If anyone knows how to write the computer code that will recognise my vocal command "next page!" or perhaps "go back a page" on my music display tablet they deserve more than a pint or two. Better still is there a way of getting the camera to recognise frantic gestures and translate them to page turns that too would be good. My home practice organ has thumb and toe pistons for page advance and page back, as I believe does the console at Kings College Cambridge but that's not much use when both hands and feet are employed simultaneously! Voice and gesture commands already exist and are in mass production as part of the "infotainment" system in a number of premium German cars. A trawl of the internet suggests that they are still not entirely successful. With voice commands unless the organist was wearing a microphone i suspect that the sound of the instrument might corrupt the vocal data reading. An innocent conversation happening behind you could also lead to some very interesting registration changes.
