Your visual acuity is the limit at which you can distinguish diagonal left and right motions.
In detail, it is the limit at which you can determine whether the left diagonal motion caused by reversal counter phase is predominant or the right diagonal motion is predominant.
When you tap screen, a diagonal motion occurs, and you can change octave of motion by pinching diagonally.
