I often go walk or ride bike and I would like to work with my cards during the walk. It would be great to implement cards control with 'blind mode' capabilityes so I could rotate and swipe cards without looking and touching the screen. Now we have 'play my cards' feature but it is something different - it playback my cards set but I do not actually controll if move card right or left So to realize the 'blind' mode it may need 2 items: voice/pronounce the card translation (native language) controll with volume button, i.e. vol+ to rotate or swipe right, vol- to rotate or swipe left also optionally may add some sounds on cards action - swipe left, swipe right and take new card from set. Scenario. I learn Romanian and my native language is ukrainian. Turn on blind mode new card taken with 'new card sound'. The word is pronounced in Romanian. I know the word. I press vol+ and it turn over card and playback translation in Ukrainian (so I recheck that I remember word correctly). I press vol+ again and it swipe card right and play 'right swipe sound) newcard opened with 'new card' sound. This time translation is shown (ukrainian) and playback in ukrainian language) I do not know the translation so I press vol- it turn around card and pronounce romanian. I press vol- again and the card swiped left for repeat <cykle repeat> Note, with this approach I can even not look at the screen. Hold phone in hend and just pressing vol+ or vol-. I can look at the road but not at phone. Also I could use bluetooth remote with vol+ and vol- so can install such remote at my bike stearing wheel and continue cykling and swiping cards with one finger press buttons on remote controller
