In one general aspect, a method can include identifying a contact on a surface of a trackpad of a computing device, calculating a value of a first speed of movement of the contact along the surface of the trackpad, calculating a value of a total distance moved by the contact along the surface of the trackpad, and blocking movement of a cursor on a display device based on determining that the value of the first speed of movement of the contact along the surface of the trackpad is less than a fast threshold speed, and based on determining that the value of the total distance moved by the contact along the surface of the trackpad is less than a threshold distance value.
