Gesture detection system
The present invention discloses a gesture detection system comprising a linear capacitive slider sensor configured to sense when a finger is close to the sensor surface, or is touching or is lifted or moved away from the sensor surface, and a direction of movements of the finger across the sensor surface, and when the finger is lifted away from the sensor surface, a combination of finger movements across the sensing surface is interpreted as a detectable gesture by the gesture detection system.
