Gestures on smartphones
Most smartphones can register at least 5 touch points.
So, I’m puzzled as to why no manufacturers have implemented gestures that involves more than one finger. Example: 4-finger swipe up for maybe screenshot or something?
Some games may require players to use 4 fingers. But still, the gestures that I am suggesting can be done is such a way that it requires swiping at the same direction (which usually isn’t likely on games). And perhaps a “feedback” when the phone is ready to register the gesture — meaning phone vibrates when it detects 4 fingers to tell user it’s ready to accept command.
