1. A method comprising:
- determining a first velocity of a detected presence of a conductive object relative to movement of the conductive object in a direction towards a surface of the capacitive sensing device;
determining a second velocity of the detected presence relative to movement of the conductive object in a direction away from the surface of the capacitive sensing device;
detecting a first peak of the first velocity in the direction towards the surface at a first time;
detecting a second peak of the second velocity in the direction away from the surface at a second time; and
recognizing a gesture based on a difference between the first time and the second time.
