17. Results Example Probability of the ‘ accidental ’ press in this area is 0.9%. 16 presses in all, 14 of them happened as the last press during a call. – which suggested those presses were intended to end the call, not happened accidentally. The other 2 presses were from 2 users. And one of them happened right before the press on ‘Exit/Back’ Button, which seemed to be an intended press too. So the only accidental press from one user happened to press on the ‘END button. The probability of the accidental ending call was 1.7% (one out of 58) . And the probability of accidental presses was very low: about 0.12% (1658 presses in all) There were 64 presses in this button area. But 38 of them (59%) happened right before ending the call, which suggested these presses were intended to close/back. So the probability of accidental press in here was 1.6% (1658 Presses in all). 83% of the all presses were happened in this area (GNB + Status Bar).
