Touch-sensitive user interface
First Claim
1. 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.

Abstract
A touch-sensitive user interface includes a sensor element providing a plurality of sensing areas, a measurement circuit coupled to the sensor element and operable to iteratively acquire measurement signal values indicative of the proximity of an object to the respective sensing areas, and a processor operable to receive the measurement signal values from the measurement circuit and to classify a sensing area as an activated sensing area for a current iteration according to predefined selection criteria, wherein the predefined selection criteria are such that activation of at least a first sensing area in a current iteration is suppressed if at least a second sensing area has previously been classified as an activated sensing area within a predefined period before the current iteration. Thus a sensing area may be prevented from being activated for a predefined period of time after another sensing area has been activated.
