> I explained my app. "Since senior citizens are not good at swiping," I said, "I made it possible for them to play by tapping." I have a similar experience. A few years ago I implemented a traditional Chinese dominoes game on Android for my grandma. (To date she still plays the game every night for two hours.) When I let her tested the game, the first thing I observed was that she was poor at dragging the dominoes to the table. So, I quickly changed dragging to tapping. (Tap a dominoe once to choose it and tap the table once to play it. To cancel a wrong choice, tap the chosen dominoe again.)
