Apparatus and method for recognizing a tap gesture on a touch sensing device

摘要

Methods and apparatus include determine velocity of a detected presence in a first direction relative to a capacitive sensing surface, during a period of time, and determine velocity of the detected presence in a second direction relative to the capacitive sensing surface, during the period of time. Methods and apparatus detect a change in the determined velocity in the first direction at a first time, detect a change in the determined velocity in the second direction at a second time; and recognize a user command based on a difference between the first time and the second time.

1. A method comprising:
using a capacitive sensor, determining capacitance associated with a conductive object through a capacitive sensing surface, during a period of time, to detect a presence of the conductive object; determining a first velocity of the detected presence in a first direction relative to the capacitive sensing surface; determining a second velocity of the detected presence in a second direction relative to the capacitive sensing surface; detecting a change in the first velocity in the first direction at a first time; detecting a change in the second velocity in the second direction at a second time; and recognizing a user command based on a difference between the first time and the second time.
