Lag and precision of Leap Motion controller, Bluetooth trackpad, and USB mouse. We measured the lag and temporal precision of 3 devices (Leap, trackpad, and mouse) for two subjects (S1 and S2). The plot shows that temporal lag (milliseconds on the left, frames on the right) for the mean (horizontal line) as well as each trial (black dot). There are 10 trials per condition per subject, but some data points are overlapping. The mean is denoted by the thick black horizontal line, and the standard deviation by the gray box.
