Aggregate keypress distributions for standard character keys in each condition across all users. The respective means and standard deviations (from left to right) are (−1.45±12.62), (−1.75±12.22) and (−1.24±13.99) pixels for the x axis, and (−4.37±9.07), (−3.94±9.60) and (−5.20±9.72) pixels for the y axis
