Patent ID: 8643621

Claim:
A touch-sensitive user interface comprising: a sensor element having a plurality of sensing areas, each of the plurality of sensing areas being selectively activated when an object is placed by a user in the proximity of a selected one of the plurality of sensing areas; a measurement circuit coupled to the sensor element and operable to acquire at least one measurement signal value indicative of the proximity of the object to the selected one of the plurality of sensing areas; and a processor operable to: receive a first measurement signal value indicating the selection by the user of a first sensing area of the plurality of sensing areas; classify the first sensing area as an activated sensing area; receive a second measurement signal value indicating the selection by the user of a second sensing area of the plurality of sensing areas; determine that the second measurement signal value was received within a predetermined period of time after the first sensing area was classified as an activated sensing area; and in response to determining that the second measurement signal value was received within the predetermined period of time, suppress activation of the second sensing area as the activated sensing area.
